Multi-detector row CT urography in the evaluation of hematuria.
Hematuria can be well evaluated with a comprehensive contrast material-enhanced multi-detector row computed tomography (CT) protocol that combines unenhanced, nephrographic-phase, and excretory-phase imaging. Unenhanced images are obtained from the kidneys to the bladder and allow optimal detection of renal calculi, a common cause of hematuria. Renal parenchymal abnormalities, particularly mass...
متن کاملMulti-detector row CT: effect of iodine dose reduction on hepatic and vascular enhancement.
PURPOSE To evaluate the impact of different iodine concentrations of intravenous contrast agent on hepatic and vascular enhancement during arterial and porto-venous phase imaging using a 4-channel multi-detector row CT (MDCT). MATERIAL AND METHODS One hundred consecutive patients referred for triphasic abdominal MDCT were randomly assigned into four groups receiving different iodine concentra...
متن کاملEvaluation of patient dose and operator dose in swallowing CT studies performed with a 320-detector-row multislice CT scanner.
Recently, attempts to develop new types of swallowing function analysis with 320-detector-row multislice CT (320-MDCT) have been reported. The present report addresses (1) patient exposure, (2) operator exposure, and (3) spatial dose distribution. For dose measurement, a human-body phantom in which 303 thermoluminescent dosimeter elements were inserted and a survey meter was used. The patient p...
متن کاملSlice wars vs dose wars in multiple-row detector CT.
he short answer is yes. At this oint in time, it seems that the soalled slice wars with regard to the umber of slices provided per comuted tomographic (CT) gantry roation may be reaching a plateau. At he same time, increasing concerns bout radiation dose due to CT exminations are fueling the efforts to educe radiation dose and leading o the beginning of the so-called ose wars. Since 1998, there...
