Need to review a CT scan from remote? There’s an app for that.

A study performed at the University of Virginia indicates that CT scans reviewed using an iPhone are clear enough for correct diagnoses to be made in 99 percent of cases. The findings were presented yesterday at the annual meeting of the Radiological Society of North America.

During the study:

CT examinations of the abdomen and pelvis of 25 patients with pain in the right lower abdomen were reviewed over an encrypted wireless network by five radiologists using an iPhone G3 equipped with OsiriX Mobile medical image viewing software. All of the patients had surgical confirmation or follow-up evaluations to confirm whether or not they had appendicitis.

Lead author, Asim F. Choudhri, MD, who is now a fellow in neuroradiology at Johns Hopkins University, commented on the quality of the mobile phone images compared to viewing original scans in a release:

The scans can be read in full resolution with very little panning, and the software allows the reader to zoom and adjust the contrast and brightness of the image. The radiologist is evaluating actual raw image data, not snapshots.
