Multidetector CT of emergent biliary pathologic conditions.
Various biliary pathologic conditions can lead to acute abdominal pain. Specific diagnosis is not always possible clinically because many biliary diseases have overlapping signs and symptoms. Imaging can help narrow the differential diagnosis and lead to a specific diagnosis. Although ultrasonography (US) is the most useful imaging modality for initial evaluation of the biliary system, multidet...
متن کاملStaging of laryngeal cancer using 64-channel multidetector row CT: comparison of standard neck CT with dedicated breath-maneuver laryngeal CT.
BACKGROUND AND PURPOSE With a 64-channel multidetector row CT, imaging acquisition during speech, swallowing, or phonation has become feasible. However, the actual benefit of these additional focused images should be critically evaluated with respect to radiation dose. The purpose of this study was to determine if dedicated laryngeal CT using breath-holding and straw-blowing improved the accura...
متن کاملWhole brain perfusion CT imaging and CT angiography with a 64-channel CT system
Due to the development of new computed tomography (CT) techniques over the last 30 years, there are a vast amount of new diagnostic options available today. When Sir G.N. Hounsfi eld invented CT [1] (based on the preliminary works of A. MacLeod Cormack), the acquisition of a single slice took more time than CT-angiography of the complete supraaortic circulation today. And, of course, the image ...
متن کاملComparison of Image Quality of Low Voltage 64-slice Multidetector CT Angiography with the Standard Condition in Patients Suspected of Pulmonary Embolism
Introduction: Reduction of peak kilovoltage (kV) setting has been a useful approach to d creating radiation dose; however, it may have varied effects on noise and the accuracy of diagnosis. Thus, we compared image quality between low (80 kV) and standard kilovoltage (100 kV) protocols. Material and Methods: This triple blind non-randomized parallel quasi-experimental study was conducted on 140 ...
