Discordant uptake of Tc-99m PMT and Tc-99m GSA by two hepatocellular carcinoma lesions.
نویسندگان
چکیده
Tc-99m PMT and Tc-99m GSA can be taken up by hepatocellular carcinoma (HCC), but there has been no report concerning HCC showing accumulation of both of Tc-99m PMT and Tc-99m GSA. In this paper we describe a case of two simultaneously developed HCCs, one of which took up both tracers but the other took up neither of them.

Imaging of medullary thyroid carcinoma with Tc-99m (V) DMSA [Persian]
Twenty-one patients with medullary thyroid carcinoma were studied prospectively with Tc-99m (V) DMSA after surgery. Pentavalent DMSA scintigram demonstrated abnormal uptake in 13 and equivocal uptake in 6 patients. Finally, seven patients with surgical or other imaging documentation were selected for this paper. Most of these patients were asymptomatic. Six patients had hypercalcitonemia ...
متن کاملBromocriptine enhances the uptake of 99mTc-MIBI in patients with hepatocellular carcinoma
(99m)Tc-methoxyisobutyl isonitrile (MIBI) is a suitable transport substrate for the multidrug resistance gene product P-glycoprotein (P-gp) and widely used for tumor imaging. Bromocriptine has been shown to inhibit the ATPase activity and the function of P-gp. We hypothesized that bromocriptine could promote the accumulation of MIBI by inhibiting P-gp activities, a feature that can be taken adv...

Objective(s): 99mTc-PSMA SPECT/CT is a cost effective alternative for 68Ga-PSMA PET/CT. The aim of this study was to directly compare these two techniques in patients with prostate cancer. Methods: 28 man with prostate cancer were studied using 99mTc-PSMA SPECT/CT and 68Ga-PSMA PET/CT in a shor...
متن کاملQuantitative assessment of hepatic function during liver regeneration in a standardized rat model.
UNLABELLED Reliable assessment of hepatic function during liver regeneration is crucial after liver surgery or liver transplantation. (99m)Tc-galactosyl human serum albumin ((99m)Tc-GSA) scintigraphy, (99m)Tc-mebrofenin hepatobiliary scintigraphy (HBS), the indocyanine green (ICG) clearance test, and the galactose elimination capacity (GEC) are common quantitative liver function tests. However,...

Tc-99m-EC is a new renal radiopharmaceutical introduced as an alternative for Tc-99m MAG3. Twenty-three normal volunteers and patients in different .stages of renal disease were evaluated with Te-99m EC and Tc-99m DTPA. The mean initial uptake of EC was significantly higher as compared to DTPA. There was a high correlation between rectangular and hand-drawn ROls for kidney and background,...
