Very-high-flow injection rate for upper abdominal CT angiography.

Background: The purpose of this study was to compare a very-high-flow injection-rate method (group A) and a conventional injection-rate method (group B) for visualization of upper abdominal arteries by multidetector helical computed tomography (MDHCT).

Methods: The subjects were 240 patients suspected to have abdominal lesions. They were randomly assigned to group A (120 patients) and group B (120 patients).

Peripancreatic arteries in thin-section multislice helical CT.

Background: The normal and pathologic anatomies of the peripancreatic arteries were demonstrated using thin-section multislice computed tomography (CT).

Methods: Triple-phase dynamic CT was performed in 304 consecutive patients without pancreatic pathology and in 22 patients with pancreatic carcinoma. CT angiographies images (2.

[Visualization of abdominal arteries by super-high-flow venous injection using multidetector helical CT].

The purpose in this study was to compare the ratio of visualization of upper abdominal arteries using MDHCT between the super-high-flow injection method (Group A) and the conventional injection method (Group B). The subjects ects were 200 patients who were randomly divided into Group A (100 patients) and Group B (100 patients). In Group A, visualization of the large arteries, including the CE, SMA, HA and LGA, was possible at a rate exceeding 96%, and that of the small arteries, including the DPA, SPDA, RGA and Cyst A, was more than 79%.

[Therapeutic effect of TAE in patients with hepatocellular carcinoma using color Doppler imaging with intravenous ultrasound contrast agent].

We evaluated the therapeutic effect of TAE in 9 nodules with hepatocellular carcinoma (HCC) using color Doppler flow imaging with an intravenous ultrasound contrast agent. The intratumoral color signal enhancement that was detected in 7 nodules resulted in complete disappearance after TAE. The other 2 nodules without color signal enhancement showed well-differentiated HCC with fatty degeneration on histological study.

[A hypertensive crisis during surgery in a patient with neuroblastoma].

Neuroblastoma is the most common solid tumour in infancy and childhood. The tumour usually produces large amounts of catecholamines. Few patients with neuroblastoma, however, were reported to have become hypertensive because of catecholamine metabolism within the tumour itself.
