320-slice CT and myocardial bridge.
1 of 2 DESCRIPTION A 29-year-old professional athlete was referred for cardiac evaluation after a syncope occurring during strenuous exercise. Twelve-lead ECG showed Brugada-like pattern ( fi gure 1 ), but both fl ecainide and genetic tests were negative. ECG Holter and echocardiogram were normal. ECG stress test showed no signifi cant ST-segment changes. In order to rule out coronary artery di...
متن کاملInfluence of Thin Slice Reconstruction on CT Brain Perfusion Analysis
OBJECTIVES Although CT scanners generally allow dynamic acquisition of thin slices (1 mm), thick slice (≥5 mm) reconstruction is commonly used for stroke imaging to reduce data, processing time, and noise level. Thin slice CT perfusion (CTP) reconstruction may suffer less from partial volume effects, and thus yield more accurate quantitative results with increased resolution. Before thin slice ...
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 کاملDosimetric evaluation of a 320 detector row CT scanner unit
BACKGROUND The technologic improvements in Multislice scanners include the increment in the X-ray beam width. Some new CT scanners are equipped with a 320 detector row which allows a longitudinal coverage of 160 mm and a total of 640 slices for a single rotation. When such parameters are used the length of the traditional pencil chamber (10 cm) is no more appropriate to measure the standard wei...
متن کاملWhole-Brain CT Perfusion and CT Angiography Assessment of Moyamoya Disease before and after Surgical Revascularization: Preliminary Study with 256-Slice CT
BACKGROUND/AIMS The 256-slice CT enables the entire brain to be scanned in a single examination. We evaluated the application of 256-slice whole-brain CT perfusion (CTP) in determining graft patency as well as investigating cerebral hemodynamic changes in Moyamoya disease before and after surgical revascularization. METHODS Thirty-nine cases of Moyamoya disease were evaluated before and after...
