PURPOSE The purpose of the study was to determine if increasing radiologist reading speed results in more misses and interpretation errors. METHODS We selected a sample set of 53 abdomen-pelvis CT scans of variable complexity performed at a teaching hospital during the study period. We classified the CT scans into 4 categories based on their level of difficulty, with level 4 representing the ...
AIM The authors evaluated radiation and skin doses absorbed by the eye lens, as well as the parotid and thyroid glands, during a low dose maxillary spiral computed tomography (CT). METHODS Three spiral CTs were carried out, one after the other, changing from time to time MAS, pitch factor, Kv and consequently, CTDI/Vol, until the minimum values detectable by the equipment were reached (MAS 28...
Contrast-enhanced 16-slice multi-detector row spiral computed tomography (MDCT) has been shown to be useful for non-invasive visualization of aortocoronary bypass grafts (CABG). This new-generation scanner could be a good alternative to the common invasive coronary angiography. In this article, we report a patient operated on with the St. Jude Medical, Inc, Symmetry Bypass System (Aortic Connec...
