Requesting Radiology Images for a Legal Case

Requesting radiology images for a legal case means asking the facility that performed each exam for the image study as well as the written report. The request names the patient, the facility, the exam type, body part and date, and the delivery format, usually DICOM on a disc or by secure download. Check the images against the reports on arrival.

Radiology images versus radiology reports in a legal case

A radiology report and a radiology image study are two different records. The report is a short document in which a radiologist describes what the images show. The image study is the set of pictures the scanner produced. In a legal case they are often stored in different systems, released by different staff and sent on different days.

The report is what most medical record sets already contain. It arrives with the visit notes as a page or two of text, dated and signed. It is easy to file, easy to quote in a chronology and easy to number with the rest of the pages.

The image study is a different kind of file. A CT or MRI exam can hold hundreds of individual images grouped into series, and it is usually stored in the facility's image archive rather than in the chart. A request for "all medical records" from a hospital may bring back the radiology reports and no images at all, because the release of information desk treats images as a separate request.

An expert who reviews imaging usually needs both. The report tells the expert what the original radiologist saw and when. The images let the expert look again, compare one exam with a later one, or check something the report does not mention. A case file that has the report but not the images forces that expert to rely on someone else's reading.

Ask for both records together and track them as separate items. If the report arrives and the images do not, the request is not finished.

Who holds the radiology images for a case?

The radiology images for a case are held by the place that performed the exam. That is usually a hospital imaging department, an outpatient imaging center, or a radiology group that reads studies for several sites. The ordering doctor's office often has only the report, because it receives the result, not the image files.

Start from the reports and bills already in the file. Each radiology report names the facility where the exam was done and the date. A facility bill or an explanation of benefits often shows the same exam with a place of service. Together they tell you where each study was performed.

A few patterns cause misdirected requests:

• The ordering doctor. An orthopedic or primary care office may list an MRI in its notes and keep a copy of the report. It rarely holds the images. Sending the image request there produces a polite "we do not have them" letter weeks later.
• The radiology group. The radiologist who signed the report may belong to a separate group with its own records process. The images still usually sit in the facility's archive, but the group may hold the report and its billing.
• Emergency department exams. X-rays and CT scans done in an emergency department are held by the hospital's imaging department, not by the emergency physicians' group.
• Merged or closed centers. An outpatient center that closed or changed owners may have moved its archive to a parent system or a storage company. The successor is the holder now.

The HIPAA right of access rule gives one useful backstop. Under 45 CFR 164.524 on the eCFR, paragraph (d)(3), a covered entity that does not keep the requested information but knows where it is kept must tell the individual where to direct the request. That paragraph is written for the patient's own access request, so do not count on the same pointer in a reply to a subpoena. (The eCFR text was current through 2026-10-14 when read on 2026-10-16.)

What a radiology image request should name

A radiology image request should name the patient, the facility, the study and the format clearly enough that the imaging department can find the exam without calling you. That means patient identifiers, the facility name, the study type and body part, the exam date or date range, the delivery format, and a request for the matching report.

Which legal basis the request rests on, a patient authorization, a patient's own access request, a subpoena or a court order, is covered in the guide to which authorization a records retrieval request needs. The rules for subpoenas and authorizations vary by state and by court, so confirm what a given request needs with the attorney on the case. Disclosures for court cases fall under 45 CFR 164.512(e) on the eCFR, which that guide walks through.

Radiology image request checklist

Every value in this table is fictional and is here only as an example.

Format deserves its own line in the request. The right of access rule, in paragraph (c)(2)(ii) of 45 CFR 164.524, says that when information is kept electronically and the individual asks for an electronic copy, the covered entity must provide it in the electronic form and format requested if it is readily producible that way. That applies to the patient's own request. For requests on other legal bases, state the format anyway; a facility that is not told will choose for you.

Copy fees for images vary by facility and by the legal basis of the request. What providers may charge is covered in the post on how much providers can charge to copy medical records.

A certification of the delivered studies can be requested at the same time. What such a statement says is explained in what a custodian of records affidavit states.

Radiology image formats a law firm receives

Radiology images reach a law firm in three main forms: a DICOM study, usually on a disc with a viewer or through a download link; printed or exported pictures such as JPEG or PDF files; and, for older exams, physical film. Only the DICOM study keeps the full set of images in the form the scanner produced.

DICOM stands for Digital Imaging and Communications in Medicine. The DICOM Standard overview on dicomstandard.org, read on 2026-10-16, describes it as the international standard for medical images and related information, implemented in almost every radiology device such as X-ray, CT, MRI and ultrasound. The same page says it is recognized as ISO 12052 and that NEMA serves as its secretariat.

The standard's own text explains why a DICOM study arrives as many files. DICOM PS3.10, chapter 7 on the DICOM file format (edition 2026d, read on 2026-10-16) says each file contains a single SOP instance, which in practice usually means one image or one object per file. A disc for one MRI can therefore hold hundreds of files with names that mean nothing to a person.

A disc made to the standard also carries an index. DICOM PS3.10, chapter 8 says a single file with the file ID DICOMDIR shall be included in each file-set. The same chapter calls it the DICOM Media Storage Directory, the index that references the DICOM files in the file-set. The standard's General Purpose CD-R, DVD and BD interchange profiles in PS3.11 define how images and related objects are exchanged on those discs.

Prints and exported pictures are a different thing. A JPEG or PDF holds whatever the person exporting it chose to show: a few images, at one brightness and contrast setting, without the rest of the series. A reviewer cannot scroll through slices, adjust the window, or measure from a print the way a DICOM viewer allows. Prints are fine for a demonstrative exhibit chosen by an expert. They are a poor substitute for the study itself.

Film still exists for older exams. If a facility offers film only, ask whether it can digitize the film or lend the originals, and record which you received.

Where the delivered images sit in the case file, and how they are named next to the reports, is covered in the guide to which folders a legal case record set needs.

Radiology image retention limits and purged studies

Radiology image retention is not the same everywhere. How long a facility keeps a study depends on state law, any federal rule for that exam type, and the facility's own policy. An exam from many years before the case may already have been purged, even when its report survives in the chart.

Mammography is one exam with a federal floor. Under 21 CFR 900.12 on the eCFR, paragraph (c)(4)(i), a facility that performs mammograms must keep the original mammograms and reports for the longest of three periods: at least 5 years, at least 10 years if the facility performs no more mammograms of the patient, or any longer period required by state or local law. (eCFR text current through 2026-10-14, read on 2026-10-16.) Other exam types do not share that rule, and their retention periods vary by state and by facility. Ask counsel which rules apply in the case's jurisdiction rather than assuming a number.

Purged images create a specific problem: the report says an exam happened, and the images cannot be produced. Treat that as a documented gap, not an open one.

• Ask for a written reply. Request a letter stating that the images for the named study and date were searched for and are no longer held, and if possible when they were destroyed.
• Ask what survives. Some facilities keep a compressed or reduced copy, a teaching copy, or film. Ask before accepting "none".
• Check other holders. A study may have been sent to another facility for comparison or to a specialist. That facility may still have a copy.

A written "no images" reply belongs in the file next to the report it refers to. The general method for these replies is in the post on no-records certifications when the gap is real.

Why won't a radiology image disc open?

A radiology image disc usually fails to open for one of a few delivery reasons: the viewer is missing or will not run, the disc holds only part of the study, the download link has expired, or the files arrived without their index. Most of these show up in the first ten minutes of checking.

The common problems, and what each looks like:

• No viewer, or a viewer that will not run. Many discs include a viewer program built for one operating system. On a different computer, or where software installs are blocked, nothing happens. A separate DICOM viewer can often read the files if the DICOMDIR file, the index the DICOM standard requires in each file-set, is present.
• Missing index. If files were copied off the original disc without the DICOMDIR file, a viewer may not list the studies at all.
• Partial series. The disc opens, but a CT shows two series when the report describes contrast and non-contrast images, or an MRI is missing a sequence the report discusses.
• Expired or locked link. Secure download links often expire after a set number of days or downloads. A link opened late, or by the wrong person, may no longer work.
• Wrong patient or wrong study. A disc labelled correctly can still hold another exam. Always check the patient name and exam date inside the viewer, not just on the label.

On-arrival check against the reports

Compare what arrived with the radiology reports already in the file. The example below is fictional.

Log the check with the date, who did it and what was found. When something is missing, send the follow-up with the study date and accession number from the report, so the imaging department can find exactly what is short.

Schema Care does not request or read image studies. It reads text documents such as medical records and billing statements into structured fields, as listed on the homepage list of document types.
