Utility of triple channel injection of contrast material with mixture of saline, with acquisition in the cephalic direction for arterial trees in the thorax using multislice computed tomography

Right Heart: Split-Bolus Injection of Diluted Contrast Medium for Visualization at Coronary CT Angiography

“…Flushing with saline solution only avoids pooling of contrast material in the injection system and in the arm veins, leading to better contrast material utilization (11) and improved bolus shaping, with more consistent and homogeneous attenuation of target vessels (6). Disturbing streak artifacts from in- flowing contrast material in the SVC and the right cardiac cavities, which may result in diagnostic pitfalls, such as artifactual stenosis of the proximal RCA due to overlying streaks (12), can be effectively avoided (6,10,14).…”

New classification of aortic dissection during the cardiac cycle as pulsating type and static type evaluated by electrocardiogram-gated multislice CT

“…MSCT is a useful tool for the diagnosis of coronary artery [20][21][22][23][24][25], myocardial [15,[26][27][28][29][30][31][32][33][34], congenital cardiac [35][36][37][38] and aortic diseases [39][40][41][42][43], and since the number of acquisition systems has increased up to 256-320 [44][45][46], ECG-gated acquisition is readily available for clinical use. One of the demerits of the procedure is that the total radiation exposure in ECG-gated acquisition in the thorax is approximately 2 times higher than that of non-ECG gated acquisition following conventional protocols using a constant tube voltage and current.…”

Positive influence of aging on the occurrence of fat replacement in the right ventricular myocardium determined by multislice-CT in subjects with atherosclerosis

“…MSCT is a useful tool for the diagnosis of coronary artery [17][18][19][20][21][22], myocardial [23][24][25][26][27][28][29][30][31][32], congenital heart [33][34][35][36], and aortic diseases [37][38][39][40][41]. Furthermore, it is also one of the most important diagnostic modalities for investigating FR in the RVM for the diagnosis of ARVC; as presented as Fig.…”
