Teleradiology for solo imaging centers: no minimums

It is late on a Tuesday afternoon and a referring office is on the phone about a knee MRI done that morning. Your technologist is mid-exam in the other room. The study is complete, archived, and sitting there with nobody on the premises qualified to interpret it, because your center has never had a radiologist on staff. Teleradiology for solo imaging centers is the arrangement that closes that gap: every study your site produces routes to a contracted panel of board-certified radiologists, each one licensed in the state where your patient is located and privileged at your facility, and each study comes back as a final signed report inside a turnaround tier you agreed to in writing. You pay per signed report. A light week costs less than a heavy one, and nothing accrues in the months when the schedule thins.

This page is written for whoever runs a single-site outpatient imaging center: the owner, the practice administrator, or the lead technologist who inherited the vendor relationship. It covers who is allowed to read your studies, why buying full coverage is a different transaction from buying overflow, how a center with no integration budget starts sending, what per-report pricing does to a quiet month, and where a part-time local radiologist is still the smarter purchase.

Who reads the studies when a solo imaging center has no radiologist on staff?

A contracted teleradiology practice reads them. The interpreting physician is a board-certified radiologist who holds an active license in the state where your patient is physically located, holds privileges at your facility through your credentialing process, and is qualified for the specific modality being interpreted. You keep the scanners, the technologists, and the archive.

Three requirements sit behind that sentence, and every one of them is checkable before you sign anything. Licensure follows the patient, so the reader's home state is irrelevant and your patients' state is not. Privileging follows your facility, which means the vendor supplies a credential file per reader that your medical staff process or your accrediting body will ask to see.

Qualification follows the modality, and that one is written down. The ACR-AAPM-SIIM Technical Standard for Electronic Practice of Medical Imaging states that the interpreting physician must demonstrate qualifications as delineated in the appropriate ACR practice parameter or technical standard for the particular diagnostic modality being interpreted, and that physicians using an image data management system for official interpretation should understand the basic technology of image acquisition, transmission, manipulation, retrieval, and display, including its strengths, weaknesses, and limitations. The same document defines the official interpretation as the written report, plus any supplements or amendments, that attaches to the patient's permanent record.

What stays with you is more than the equipment. Your technologists acquire to your protocols, your front desk fields the call from the referring office, and your center remains the entity billing the technical component.

A remote reader can advise on a protocol question and can call your technologist back for an extra sequence. A remote reader cannot walk into the room, supervise a contrast reaction, or stand at the ultrasound machine while a difficult study is being acquired. That is the honest boundary of this arrangement, and the section below on part-time local coverage takes it seriously.

Full coverage is a different purchase from overflow

Overflow is a relief valve attached to a reading room that already exists. Full coverage means the vendor is your reading room. The two arrangements share a rate card and share almost nothing else, and single-site operators get burned when they buy the first while needing the second.

The difference shows up in the failure modes. When an overflow vendor runs late, a study sits a little longer in a queue that your own radiologists are still watching. When a full-coverage vendor runs late, a referring physician calls your front desk and your staff has no answer to give. Depth of panel, breadth of modality coverage, and the escalation path all have to be sized for the second case.

This table sets the two purchases side by side on the questions a single-site operator actually has to answer.

Question	Overflow reads	Full single-site coverage
What routes out	The studies your readers cannot reach	Every study the site produces
Whose turnaround your referrers experience	Yours, with the vendor absorbing peaks	The vendor's, on every study
Modality breadth required	Whatever the in-house roster is short on	Every modality on your floor, mammography included
Credentialing scope	Enough readers to cover the peak	Enough readers to cover the whole schedule, including holidays
Effect of a missed turnaround tier	A study waits in a queue you still control	A referring office calls your front desk
Subspecialty gaps	Filled selectively, study by study	Filled permanently, across the whole study mix
Cost of stopping	You return to your baseline roster	You have no baseline roster to return to

Read the last row twice. A center with no staff radiologist has handed a clinical function to a vendor, so the contract has to carry a real exit: a notice period you can actually live inside, a commitment to keep reading through the transition, and a clean export of your reports. Month to month with 30 days notice is the shape to ask for. If you are adding coverage on top of an existing roster instead, the mechanics are different and the economics are documented on our page about overflow radiology reads.

Three clauses do most of the work in a full-coverage agreement, and none of them is standard boilerplate. The first is an escalation path that reaches a radiologist by phone, with a named contact and a stated time to answer, because your front desk is going to need one on a Saturday. The second is a monthly performance report broken out by turnaround tier, listing every study that fell outside its tier with a cause attached, which is the only way a single site can tell a bad week from a bad vendor.

The third is a written critical results pathway that names who calls whom. At a hospital, a critical finding reaches an emergency physician who is already in the building. At your center, the patient is usually in a car on the way home and the ordering clinician is at a different address, so the vendor has to phone the ordering practice directly and document the call with a time and a recipient. Get that written down before the first study moves.

One panel across every modality your one site scans

One panel that reads everything you scan is worth more to a single site than a marginally better rate on one modality. Your floor produces plain film, ultrasound, and cross-sectional work, often mammography, sometimes nuclear medicine. Splitting that across three vendors means three contracts, three credential packets, three report formats, and three phone numbers when something goes wrong at four in the afternoon.

Subspecialty routing is what makes consolidation safe. A knee MRI goes to a musculoskeletal reader, a screening mammogram to a breast imager, a staging PET-CT to a nuclear medicine physician, and a stroke protocol head CT to a neuroradiologist. AstraRad routes by modality and body part before interpretation begins, across a panel of board-certified, fellowship-trained subspecialists covering ten subspecialties: neuroradiology, musculoskeletal, body, chest and thoracic, cardiac, breast, pediatric, emergency and trauma, nuclear medicine and PET-CT, and oncologic imaging. Turnaround and quality commitments sit on the SLA and quality page.

Mammography is the modality that most often falls out of a general teleradiology contract, and it is the one with the strictest federal floor. Under the Mammography Quality Standards Act regulations at 21 CFR 900.12, an interpreting physician has to satisfy initial qualification requirements, continuing experience measured in interpreted examinations over a defined period, and continuing education measured in credit hours. A vendor either maintains readers who meet that standard or it does not read your mammograms. Ask directly, and see telemammography coverage for how the requirement is handled in practice.

The rest of the mix is more ordinary but no less worth confirming in writing. X-ray and ultrasound reads usually make up the bulk of a single site's volume by count, while MRI teleradiology carries the studies where subspecialty training changes the report. Our segment page on teleradiology for imaging centers sets out how the whole mix is priced and covered together.

Starting with no PACS project: portal upload or DICOM push

There are two ways to send studies and neither one is an integration project. Route DICOM directly out of your PACS or modality-attached archive over a site-to-site VPN or TLS, with priors and order data attached. Or upload through a browser portal. Nothing installs on your side in either case.

Portal upload is how many single-site centers start, often on day one, because it needs no cooperation from an equipment vendor and no scheduled downtime. DICOM push is where most of them end up, because it removes a manual step from the technologist's day and carries the prior studies automatically. Running the portal for the first few weeks while the DICOM route is configured and tested is a normal sequence.

Image fidelity is a written standard, not a vendor preference. The ACR technical standard for electronic image transfer states that the image data set created by the modality for diagnostic interpretation should be transferred with full spatial resolution and full contrast resolution, and that the DICOM standard is to be used for those transactions. The same standard notes that images interpreted off-site need not be stored at the receiving facility provided they are stored at the transmitting site or its designee, which is why your archive stays yours and your retention policy stays your retention policy.

What travels with the study matters as much as how it travels. A remote reader who receives images with no clinical indication, no ordering physician, and no prior comparison will either produce a thinner report or call your technologist to ask, and incomplete order data is the most common reason a study bounces back at a single site. Build the fields into the modality worklist entry once and the problem stops recurring.

Reports come back the way results already come back. A PDF in the portal covers a center with no downstream system. An HL7 ORU^R01 message drops the signed report into your RIS. A FHIR DiagnosticReport does the same for a modern EHR, so reports land in Epic, Cerner, Meditech, or Athena the same way any other result does, and your referring physicians see them where they already look. The connection detail for each path is on our guide to PACS integration for teleradiology.

What per-report pricing does to a month that came in light

Per-report pricing means a light month is a cheap month. You pay one price per signed report, priced by modality and complexity, with a multiplier for each faster STAT speed printed on the rate card and itemized on every invoice line. No minimum, no subscription, no platform fee, no per-seat charge, no onboarding or integration fee.

A single site's volume is not a smooth line, and the operator knows it better than any vendor does. A snowstorm empties a morning schedule and those studies never come back, because the patients rebooked with somebody closer to home. A referring practice's senior physician takes two weeks off and the ultrasound room goes quiet for exactly those two weeks. A payer changes a prior authorization rule and MRI volume steps down for a quarter while everybody adjusts. A new scanner arrives and volume steps up faster than anyone forecast. None of that is manageable, and none of it should be expensive. Under a per-report model the invoice moves with the schedule in both directions, which is the only pricing shape that matches the underlying business. Under a minimum, the quiet months are the ones that hurt twice: less revenue in, and a floor you still have to pay. That is why the absence of a minimum matters more at one site than at twenty, where the law of averages does the smoothing for you.

Benchmarking is harder than it looks, because the headline rate is rarely the whole price. Many buyers anchor on the professional component published in the CMS Physician Fee Schedule as a floor, then compare quotes against it. That works only if you also count the line items that never appear in a headline rate: minimums, platform and portal fees, per-radiologist licensing charges, critical results callback fees, annual escalators, and exit penalties. We catalogued the ones that show up most often in hidden fees in teleradiology contracts, and the shape of the model itself is on the per-report pricing page.

The comparison that actually settles it takes an afternoon. Price your last full month of studies, broken out by modality and priority tier, against each vendor's complete rate card as a single mock invoice with every fee applied. Divide by the study count. That number is your real cost per read, and it is frequently not the vendor with the lowest advertised rate.

Where a part-time local radiologist still beats outsourcing

A local radiologist who comes in one or two days a week beats a remote panel for everything that requires a physician in the building. Fluoroscopy and ultrasound-guided procedures need a body in the room. So does supervision of contrast administration under most state and accreditation rules, and so does a same-room conversation with a technologist about how a difficult study should be acquired.

There is also the relationship layer, which is easy to undervalue until it is gone. A radiologist who lives in your referral area knows the orthopedic group by name, takes their calls, and tells them things a report never will. That familiarity brings volume. No teleradiology contract reproduces it, and any vendor that claims otherwise is selling you something.

Accreditation is the third piece. Programs generally expect a supervising or medical director physician who is accountable for the imaging performed at your facility, and that role sits more naturally with someone who is periodically on site. A remote panel can supply the interpretations and the peer review data that the program asks about, and it does not by itself supply the supervising physician.

The arrangement that works for a lot of single sites is both. A part-time local physician holds the on-site duties, the medical direction, and the referral relationships. The remote panel carries the interpretation volume, the modality breadth no single reader covers, the evenings, the weekends, and the vacation weeks that would otherwise stall the schedule. Our comparison of in-house versus outsourced radiology works through where each side of that split pays for itself.

How AstraRad covers a single-site imaging center

Every study your center sends is read and signed by a board-certified, fellowship-trained subspecialist matched to the study by modality and body part, and licensed in the state where your patient is located. Turnaround runs on contractual tiers, STAT under 4 hours, with 2-hour and 1-hour STAT available on request at a higher multiplier, and routine 24 to 48 hours, measured from last-image arrival to radiologist signature, with the measurement methodology published in full. Nights are a committed, scheduled shift with a fixed rest interval for the reader, and every read is performed inside the United States.

Every report is final. There is no preliminary tier, which matters more at your site than at a hospital, because a preliminary read has to be finalized by a qualified physician and your center does not employ one. The clinical and billing consequences of that distinction are worked through in our page on preliminary, STAT and final reads.

The commercial terms are built for a business with one schedule and one bad week at a time. Per signed report, no minimums, no subscriptions, no platform fee, no per-seat charge, no onboarding or integration fee. Each faster STAT speed carries its own multiplier, printed on the rate card and visible on every invoice line. The agreement runs month to month with 30 days notice, and a complete written rate card arrives within one business day of a request.

On the diligence questions, plainly. AstraRad operates as a business associate under a signed BAA, is HIPAA aligned, is built to the HIPAA Security Rule safeguard categories, and is DICOM conformant. AstraRad does not hold SOC 2, ISO 27001, HITRUST, or Joint Commission accreditation, and says so instead of implying otherwise. No AI pre-read, no AI triage, and no AI-drafted report text happens anywhere in the workflow, and no client imaging is used to train any model. Every interpretation is performed and signed by a physician.

If your center runs without a radiologist on staff, the fastest way to price the change is to send us your study mix by modality and priority tier for a recent full month. A complete written rate card comes back within one business day, and you can set it against what that month cost you.
