Abstract

CTC image on the iMac®, showing small polyp in the ascending colon..CTC reading on the iPhone®. Complete visualization of the entire colon... CTC reading on the iMac®. Exporting JPEG capture of the polyp on the iPhone®.Purpose CT colonography (CTC) is gaining widespread acceptance for minimally invasive evaluation of the large bowel, and has increasingly been used as a diagnostic complement in case of incomplete optical colonoscopy or for colorectal cancer screening purposes. In parallel with the evolution of CT technology and the related improvement of CTC diagnostic accuracy, new tools for visualization and management of CT images have been developed. In this latter setting, open source software (such as... read more Methods and Materials We retrospectively reviewed 67 CTC examinations performed in a colorectal cancer screening setting. CTC images had been acquired in the supine and prone position using a low radiation dose and a fecal tagging protocol based on oral administration of iodinated contrast material. All datasets were wirelessly imported in DICOM format on a iPhone 4® 32GB (Apple Inc, Cupertino, CA) running the OsiriX iPhone app version 1.1.3 (www.osirix-viewer.com) from a Macintosh desktop computer (iMac®... read more Results All lesions diagnosed on the iMac® were also detected on the iPhone®.
