How the Exchange works for Hospitals, Imaging Centers, Physician Offices, and Night Reads

After you have signed up and been connected by our PACS partner, completed studies are auctioned to qualified radiologists for competitive bidding. When you sign up, you have the option of setting a maximum price for each type of study to ensure costs are controlled. The auction process allows qualified radiologists to bid competitively to drive down the price you’ll have to pay to have your study interpreted. You can allow any qualified radiologist in your state to bid on a study or restrict bidding to your preferred or sub-specialized radiologists. RadBay only lets radiologist that are caught up on their work to bid. Once a study is auctioned, the radiologist is required to interpret it and sign off on the report in a pre-specified time. The time is different based on the priority (stat, ASAP, routine) of each study. You may use your own transcriptionist or allow us to connect you to a preferred transcription service. You are then billed by RadBay and the radiologist is paid by RadBay, thus completing the transaction. With a vast pool of radiologists and the ability to add and remove radiologist with ease, quality can be maintained to the highest standard and the fastest report turnaround can be achieved. In addition, radiologist have the opportunity to give technologist feedback on every study. You can get reports from this feedback, allowing you to see how you can improve the quality of your studies.

Summary of RadBay Benefits


The auction process allows the hospital or imaging center to pay the lowest rate for interpretations on each study, keeping more of the global charge.


Imaging centers and hospitals can pick from a list of all licenced radiologist in their state, regardless of geographic location. If they experience problems with the reports of a radiologist, they just remove him/her from their list. There is no longstanding contract with a radiologist, politics, or privilege issues to prevent removal from the list.

Every study can be read by a radiology sub-specialist, giving even the smallest communities the level of radiology care previously only achievable at large academic centers.

Radiologists can easily give electronic feedback on every study, so radiology directors can get hard data on what can be improved in their department.

With or without a local PACS, our cloud PACS can act as a backup PACS for your facility (without additional charge).

Rapid delivery of care

RadBay monitors the workload of each radiologist and does not let them bid on new work until they are caught up, insuring rapid report turnaround.

Credentialing/ Governmental

You can do your own credentialing from the information that we collect from radiologist when they sign up, or pick from a list of radiologists that are credentialed through a Joint Commission Certified process. With patient studies archived in the cloud PACS, if a patient goes to a different center or even a different state, their images are readily available, moving toward the federal government’s goal of easy access to electronic medical records.


The American Radiology Exchange, LLC believes in supporting local communities and seeks to donate a portion of every dollar earned on RadBay to support local nonprofits. Imaging centers are encouraged to recommend a local non-profit for RadBay to support.

FAQs by Hospitals & Imaging Centers

Q: We prefer certain radiologists to interpret our studies. Can we restrict bidding to these radiologists?
A: Yes, but the more radiologists you allow to bid on a study, the less you are likely to pay and the report turnaround will be faster.
Q: I already have a PACS, do I have to use yours?
A: Your studies will be sent to both your PACS and the RadBay PACS. Most imaging centers are required to have offsite backup storage, so you may also save by having RadBay be your backup storage and PACS.
Q: How can I be sure that I am not paying too much for each study?
A: Administrators can set a maximum interpretation price per CPT code. This allows you to ensure profitability.
Q: How are reports sent to my imaging center?
A: You can receive reports by email, fax, and electronically to your RIS. You can also have a report automatically sent to the referring physician.
Q: How quick is the report turnaround?
A: While the required times may be changed in the future, the are currently set at:
Studies are auctioned for 15 minutes.
Stat: 1 hr to read, 1 hr to sign
ASAP: 3 hrs to read, 3 hrs to sign
Routine: 8 hrs to read, 16 hrs to sign
Q: Can call report studies be auctioned?
A: Yes. All the necessary information is transmitted to the winning radiologist.
Q: How much does RadBay Cost?
A: RadBay charges a small per-study fee to cover the cost of the hosted PACS and a small percent of the auction price, but these fees may be waived for Beta customers. Facilities experience a net savings over contracting directly with radiologists and radiology groups.
Q: What if no one bids on my study?
A: Because of the efficiency of the free market system, if you have not severely restricted the number of bidders, almost all studies should have a successful auction. If your study is not auctioned, you can choose to be notified or have a RadBay backup reader interpret the study at our fixed rate.
Q: What do I do if I am unhappy with interpretations by a particular radiologist?
A: RadBay allows each imaging center to exclude any radiologist from bidding on the imaging center’s studies.
Q: What if a technologist has a question about a study that has been ordered?
A: When the referring physician or the imaging center medical director is unable to answer a question, a RadBay radiologists is on duty to provide advice for such questions. Users agree to receive calls from technologists with medical questions for the protocoling of studies. RadBay attempts to distribute these calls in proportion to the amount of work won on RadBay for that imaging center. In addition, RadBay can provide imaging centers with generally accepted protocols at the imaging center’s request.
Q: What type of studies can I submit for auction?
A: Currently, we allow the auction of CRs (plain films), CT, MRI, Nuclear Medicine (including PET), mammography, and Ultrasound. Post processed CTA and MRA can also be auctioned. There may be some limitations on 3D imaging based on our PACS (this can be discussed with our PACS partner upon sign up).
Q: Are old studies available for radiologist comparison?
A: Yes, technologists are allowed to upload old studies for comparison without charge. In addition, any studies previously auctioned on RadBay are available for comparison as long as the imaging center uses the same patient identification number.
Q: Does RadBay provide credentialing?
A: We collect credentialing information from the radiologists and provide it to the imaging centers. The imaging center can contact the radiologist directly if they need more information before allowing him/her to bid on any studies. In addition, you can also pick from a list of radiologists that are credentialed through a Joint Commission Certified process.
Q: Are you HIPAA compliant?
A: Yes. RadBay handles auctioning the studies. Patient information stays on the PACS server and is never transmitted to RadBay. The winning radiologist, referring physician(s), and imaging center personnel are the only ones that can see the images on each study.
Q: How do I track my studies if we don’t use accession numbers?
A: If you do not use accession numbers, RadBay will create a unique number to track studies on RadBay and the RadBay PACS.
Q: What about contrast coverage?
A: There are various ways to integrate contrast coverage with the system which we can discuss with you.
Q: Can I use RadBay as a “nighthawk” service?
A: Yes, you can use RadBay for preliminary and final interpretations 24/7.
Q: What web browsers are supported by RadBay?
A: RadBay supports the following browsers: Internet Explorer 8, Firefox 4, Chrome, and Safari 4. Please note the PACs system used by RadBay requires IE.
