    Notes: Abstract We performed blinded visual evaluation of MR angiography (MRA) films in 44 patients with unilateral carotid artery stenosis to determine whether a flow gap and poststenotic signal attenuation on 3 D-PC MRA were useful signs of severe carotid artery stenosis. Although nine patients with a flow gap alone had various degrees of stenosis ranging from 22.2 to 77.3 % without any decrease in regional cerebral blood flow (rCBF), 13 patients with both a flow gap and poststenotic signal attenuation had severe stenoses of 80 % or more, with a definite decrease in baseline rCBF. The presence of both a flow gap and poststenotic signal attenuation on 3 D-PC MRA appeared to be a reliable marker of severe carotid artery stenosis with a decrease in rCBF.

    Comparison of delayed hepatobiliary imaging using 99mTc-Sn-N-pyridoxyl-5-methyltryptophan and 67Ga-citrate imaging for diagnosis of hepatocellular carcinoma (1988)

    Notes: Abstract Images were obtained both with a biliary agent, 99mTc-Sn-N-pyridoxyl-5-methyltryptophan (99mTc-PMT), and with 67Ga-citrate in 40 cases of hepatocellular carcinoma and in 43 cases of other hepatic diseases and results were compared. Positive results were obtained by delayed 99mTc-PMT imaging in 25 (63%) of 40 cases of hepatoma: the hepatic tumor showed increased uptake in 18 cases (45%) and equilibrated uptake in 7 cases (18%). Positive 67Ga-citrate imaging was found in 28 (70%) of the 40 cases of hepatoma: increased uptake was seen in 24 cases (60%) and equilibrated uptake in 4 cases (10%). Of 15 cases of hepatoma giving negative results in the 99mTc-PMT study, 7 cases (47%) took up 67Ga-citrate, and 6 of these showed increased 67Ga-citrate uptake by the hepatic tumors. A certain relation existed between the degree of histological differentiation of hepatomas and the intensity of 99mTc-PMT uptake by those tumors, while such a histological correlation was denied for 67Ga-citrate uptake by the tumors. Delayed 99mTc-PMT imaging is preferable to 67Ga-citrate imaging for increasing the specificity of diagnosis of hepatoma. 67Ga-citrate should be used in those cases that do not give positive results with 99mTc-PMT.
