independent-dr Services

  • Expert Interpretations

    independent-dr provides expert interpretation of MRI, CT, nuclear medicine, ultrasound and plain film radiography from independent imaging centers and attorneys.

  • Guaranteed Accurate and Consistent Readings

    We promise accurate and consistent readings by a board-certified fellowship-trained MRI specialist with a Ph.D. in magnetic resonance.

  • Quick Turnaround Times

    Turn-around time for primary clinical interpretations is usually within 48 hours. Second opinions are usually read within 4 weeks, but upgrades to ASAP can be arranged by phone for an additional fee.

  • Legal Exhibits

    Dr. Herbst makes basic grayscale posters and advanced legal exhibits with colorized and labeled images, PowerPoint presentations, 3D reconstructions, rotating videos of 3D reconstructions, narrated tours of imaging studies, and fly-through videos. Solid 3D-printed models are also available.

Frequently Asked Questions

In most cases, the MRI may be read without any prior images for comparison. However, it is always easier to make a confident MRI diagnosis when you have the priors for confirmation. Tentative diagnoses of calcific tendinitis, osteophytes, myositis ossificans, fibrous dysplasia, fibrous cortical defects, encondromas, hematoma, hemorrhages, and fractures are made obvious when the MRI scan is correlated with plain films or CT scans or bone scans. In fact, about 5-20% of readings change with plain film correlation at the time of the reading. For example, an interpretation without plain films may read ‘narrow desiccated disc bulge or protrusion or osteophyte…’ while the same scan read in conjunction with the plain films can state ‘left posterolateral osteophytes compressing the cord 20% at C4-5.’

If prior images are required, but not delivered within 3 business days, a report will be issued without correlation. Reports done later, after delayed arrival of previous images, will incur new charges as if the images are being read for the first time.

All studies are reviewed without history first, so that the history does not bias the interpretation of the images. Then, the history is reviewed and the study is reviewed again if the clinical question has not been answered, so that the interpretation can be tailored to the needs of the patient.

For the best MRI interpretation, the referring physician should provide a complete history. The reading will address any findings that may be responsible for the patient’s symptoms. Any specific questions will be answered in the impression. A copy of office notes or previous operative notes would be helpful. Any previous films including CT, MRI, nuclear scans or plain films that are supplied will be correlated with the MRI scan and returned promptly.

Of course, attorney reviews are different, because we do not require any prior reports or medical history up front. We review the images alone for whatever they show, and report those findings back to the referring attorney. During a telephone conference that includes showing the images via screen sharing, we ask for any history to see if it changes the interpretation of the images.

We dropped “St. Petersburg” from our name in 2012. Although we are still proud to be in St. Pete and to work in the Tampa Bay area, shortening our name makes it easier to say, reflects our expanding customer base outside the State of Florida, and avoids a confusing acronym. We are now called “Independent Diagnostic Radiology.” You can depend on us for independent, unbiased, expert radiology interpretations, with a smile.
