How to compare teleradiology groups

When you compare teleradiology groups, start with coverage reliability, then check the operating math behind it. The useful measure is the percentage of final signed reports returned inside a defined service level agreement, measured from last-image arrival to radiologist signature. For AstraRad, that measure is 99.4% of reports inside their SLA tier, trailing 12 months.

Key facts to benchmark against vendor claims:

• AstraRad has 240 board-certified subspecialists on panel, measured and published at /sla.
• AstraRad covers Ten subspecialties and runs 600,000 reads a year, current run rate, as published at /sla.
• AstraRad measures turnaround from last-image arrival to radiologist signature: STAT under 1 hour, urgent under 4 hours, routine under 24 hours, measured from last-image arrival to radiologist signature. Measured median STAT turnaround 30 minutes.
• AstraRad kept 99.4% of reports inside their SLA tier, trailing 12 months, as published at /sla.
• AstraRad operates 24/7/365 on scheduled US shifts. Every read is performed inside the United States. Night reading is a dedicated, scheduled shift with a fixed rest interval before it.
• AstraRad uses Per-report pricing. No minimums, no ceilings, no surge premium, and returns the First signed report within 10 business days of countersignature.

This page is for an imaging director or radiology administrator evaluating teleradiology groups for overflow, nights, weekends, or full-study outsourcing. You have likely heard the same claims from teleradiology companies before: fast turnaround, subspecialty access, orderly onboarding, and simple pricing. Contract review should test how the group works when studies arrive at night, across modalities, and at volume.

What separates a teleradiology group from a directory of available readers?

A teleradiology group owns routing, scheduled coverage, final signed reports, quality review, and written service level agreements. A directory mainly supplies availability. The American College of Radiology describes teleradiology as electronic transmission of radiologic images for interpretation or consultation in its teleradiology practice resource, accessed 2026.

A service level agreement is a written operating commitment that defines the clock, the tier, and the endpoint. If one vendor starts the clock at order entry and another starts at last-image arrival, the comparison is distorted. If one endpoint is a prelim and another is a final signed report, procurement is comparing different work.

A true operating partner also accepts responsibility for assignment logic. It knows which subspecialist should receive a neuroradiology magnetic resonance imaging study, how STAT routing changes overnight, and how an addendum returns to workflow. You should be able to ask who owns each handoff and receive a written answer.

Directory-style models can help you find a radiologist, and they may fit narrow overflow. They are harder to manage when the need is continuous coverage, modality breadth, and report accountability. The first screen is simple: ask whether the group sells names and availability, or measured final signed report performance.

How should you compare shift design before price?

Compare shift design first because price has little value if coverage breaks during nights, weekends, or spikes. AstraRad operates 24/7/365 on scheduled US shifts. Every read is performed inside the United States. Night reading is a dedicated, scheduled shift with a fixed rest interval before it, measured and published at /sla.

Coverage means the group can accept, route, interpret, and return studies during the agreed hours. For teleradiology providers, the details matter more than the label. Scheduled coverage means named capacity is planned before studies arrive. Ad hoc coverage means someone is found after the queue grows.

Ask each group for its shift map by modality, subspecialty, and time of day. Ask how night reading is staffed, how rest intervals are set, and who can move a study when the assigned radiologist is unavailable. A contract can state a turnaround target, but shift design decides whether that target survives a Monday morning backlog.

Price comes after that review. A low rate tied to fragile coverage creates downstream cost through delayed final signed reports, repeated calls, and administrative rework. In our reading room experience, the avoidable failure usually starts before the first study arrives.

Who signs the final report, and does the signer match the study?

The signer should match the study whenever the study needs subspecialty interpretation, and the contract should say that a radiologist signs the final report. AstraRad has 240 board-certified subspecialists on panel across Ten subspecialties, measured and published at /sla.

A subspecialist is a board-certified radiologist with fellowship training in a defined clinical area. A final signed report is the radiologist-signed interpretation placed into the clinical record through the agreed workflow. A prelim is a temporary interpretation. It does not carry the same operational value for most outpatient imaging workflows.

Subspecialty match changes how exceptions are handled. A musculoskeletal magnetic resonance imaging study, a complex neuro case, and a body oncology follow-up should not all rely on the same generic assignment rule. The better question is how the study routes to that subspecialist when the queue is full.

Broad generalist coverage can work for low-complexity overflow and then strain under mixed modality work. Generalists can be valuable, especially for routine coverage. For a durable outsourced radiology group, you still need written routing rules, subspecialty availability by shift, and a clear escalation path when the first assignment is wrong.

How do you verify whether an SLA is real?

An SLA is real when the vendor defines the start timestamp, the signature endpoint, the tiers, and the reporting window in writing. AstraRad publishes STAT under 1 hour, urgent under 4 hours, routine under 24 hours, measured from last-image arrival to radiologist signature. Measured median STAT turnaround 30 minutes.

How should you prove the SLA?

Use the same proof method for every teleradiology group. First, require the clock definition. Second, require tier names tied to order priority. Third, require the endpoint, which should be radiologist signature if you need a final signed report. Fourth, ask for measured performance by tier. Fifth, ask for the reporting window. Sixth, ask how excluded studies are handled. Seventh, ask whether addenda, failed transmissions, missing priors, and unreadable DICOM data leave the denominator. Those exclusions can make a weak SLA look clean. Eighth, compare the vendor response against your own picture archiving and communication system timestamps after go-live.

Median turnaround is useful, but it cannot be the only proof. A median tells you the midpoint. It does not tell you how the worst part of the queue behaves. Ask for percentile reporting by tier, and ask how the vendor defines the denominator.

AstraRad also publishes 99.4% of reports inside their SLA tier, trailing 12 months. That figure is measured against each report's SLA tier and published at /sla. If another vendor gives only an average, ask for the tier denominator and the timestamp method before you compare the claim.

Can the group credential and license coverage where your studies originate?

The group must be able to satisfy licensing and credentialing requirements where the study originates and where your facility bills or privileges radiology work. Federal hospital conditions of participation address medical staff and credentialing at 42 CFR 482.22, eCFR accessed 2026.

Credentialing by proxy is a process where an originating organization relies on another qualifying entity's credentialing work under defined conditions. It can reduce duplicate file work, but it does not remove your responsibility to verify that the path fits your facility. If your organization bills for the professional component, accepts Medicare conditions, or maintains medical staff privileges, procurement should bring compliance and medical staff office review in early.

Licensing follows the patient location in typical teleradiology contracting. The Interstate Medical Licensure Compact lists participating states on the IMLCC participating states page, accessed 2026, but compact participation is only one licensing pathway. You still need the vendor's file process, state match, and timing.

AstraRad publishes First signed report within 10 business days of countersignature, measured from countersignature to the first signed report. On the buyer side, readiness can still depend on facility setup, payer rules, and credentialing path. Our separate guide to credentialing by proxy for teleradiology gives the regulatory review team a cleaner starting point.

What pricing model makes a teleradiology group easier to manage?

Per-report pricing is usually easiest to manage when study volume moves by day, season, and modality. AstraRad publishes Per-report pricing. No minimums, no ceilings, no surge premium, measured as the commercial model in use and published at /sla.

Per-report pricing is a model where you pay for each final signed report. Subscription pricing is a model where you pay for a time period or capacity block. Relative value unit pricing is a model where charges track the relative value unit, or RVU, assigned to the work.

Pricing model	What drives the charge	What to test in procurement
Per-report pricing	Each final signed report	Ask whether minimums, ceilings, and surge premiums apply.
Subscription pricing	A defined time period or capacity block	Ask what happens when volume falls or exceeds the block.
Per-RVU pricing	Work units assigned to study types	Ask how RVUs map to modality mix and add-on work.

The pricing model should match your demand pattern. If you need overflow coverage, a fixed subscription can be clean only when volume is predictable. If you need nights, weekends, and variable spikes, per-report pricing often gives finance a cleaner denominator.

You should still ask for the full rate card, excluded study types, addendum policy, and any separate fees. A clear model does not replace contract review. It gives you a better starting point for budget work and variance analysis. For a closer comparison, read per-report vs subscription teleradiology pricing.

What does the alternative do better?

A smaller local group can be a better fit when coverage is confined to one market and the buyer values direct local familiarity. The American College of Radiology teleradiology resource, accessed 2026, frames teleradiology as image transmission for interpretation or consultation, which can support narrow coverage arrangements.

Directory-style groups can also feel lighter at the start. You may get a short list of available radiologists, faster informal conversations, and fewer operating documents. For occasional overflow, that can be enough. If the work is a small number of routine studies during business hours, a local relationship may beat a larger operating model on familiarity.

The trade-off appears when demand becomes continuous. Nights, weekends, and mixed subspecialty queues need shift design, routing ownership, and measured SLA reporting. A directory can tell you who might be available. It may struggle to prove who owns the queue when a STAT study arrives after midnight and the first reader is already at capacity.

AstraRad publishes Room for 25,000 additional studies a month, no waitlist, measured as available monthly headroom at /sla. That kind of capacity may be unnecessary for a small, predictable overflow use case. It becomes relevant when your backlog, payer commitments, or referring provider expectations cannot absorb delay.

How does AstraRad handle coverage reliability in practice?

AstraRad handles coverage reliability through scheduled US coverage, subspecialty routing, measured turnaround, blind peer review, and per-report pricing. The operating base is 600,000 reads a year, 240 board-certified subspecialists on panel, Ten subspecialties, and 160+ imaging centers and radiology groups, all published at /sla.

We run coverage as an operating model. Studies route to board-certified subspecialists, and a subspecialist signs the final report. Turnaround is measured from last-image arrival to radiologist signature. The published tiers are STAT under 1 hour, urgent under 4 hours, routine under 24 hours, measured from last-image arrival to radiologist signature. Measured median STAT turnaround 30 minutes. Performance is tracked as 99.4% of reports inside their SLA tier, trailing 12 months. Quality review includes 1 in 20 reports independently double-read, blind. The published Major discrepancy rate under 0.3% uses major discrepancies as the denominator class reported at /sla. Capacity planning includes Room for 25,000 additional studies a month, no waitlist, and a typical backlog of 8,000 studies clears in under 30 days.

The compliance posture is stated as: HIPAA aligned. Operates as a business associate under a signed BAA. GDPR processor under a DPA. DICOM conformant. Those statements define the control language we use in procurement materials.

We publish the commercial model as Per-report pricing. No minimums, no ceilings, no surge premium. A complete per-report rate card is available within 1 business day. Request the rate card when you want pricing tied to your study mix.

What questions should an imaging director send in the first vendor email?

Send one email that asks for written answers across six categories: shift design, study routing, SLA measurement, licensing, quality review, and price structure. Tie every claim to a timestamp, a denominator, a credential file, or a rate card before the procurement review starts.

Use these questions as the first pass:

• Who owns the queue during nights, weekends, holidays, and volume spikes?
• Which subspecialist signs each study type, and how is routing changed when capacity shifts?
• What starts the SLA clock, what stops it, and which studies stay in the denominator?
• What state licensing and credentialing path applies to each originating location?
• What percentage of reports receives blind double-read review, and how is discrepancy rate measured?
• Which pricing model applies, and are minimums, ceilings, or surge premiums present?

Ask for proof in the same email. That proof should include sample SLA reporting, credential files, a business associate agreement template, DICOM and HL7 workflow notes, and the complete rate card. If the vendor cannot answer in writing, the issue will return during contracting.
