| 内容記述 | To distinguish hepatocellular carcinoma (HCC) from normal liver tissue, a color map was made by dynamic contrast-enhanced 256-detector row CT developed at our institute. Dynamic enhanced CT of the liver of three patients with HCC was studied. The CT has 912 (transverse) x 256 (cranio-caudal) elements, each measuring approximately 0.5 mm x 0.5mm at the center of rotation. Scanning for 10 s (1.0 s/rotation) was started 30 s after intravenous injection of contrast medium. The reconstruction increment was 0.62 mm with a time interval of 0.1s and a matrix size of 512 x 512 x 256. Color maps were generated to show the gradient of the regression line of the time-density change. Due to volume acquisition, the 3D color map can be created using continuous 10-s scanning. The densities of the HCC and liver were decreased and increased during scanning, respectively. The HCC was detected clearly in the color map as a downward-sloping region. Dynamic enhanced 256-detector row CT could be useful for detecting malignant tumors in the liver with a short scan time. | |||||
