葡庚糖酸钙(GH)用~(99m)Tc标记后(~(99m)Tc-GH)静脉注射370～740 MBq、于1～2h和4～6h拍照肝前位、右侧位和后位图像。结果发现31例肝恶性病变(包括转移癌)17例强阳性,占54.8％;6例阳性,占19.4％;总阳性率74.2％。其阳性率低于~(67)Ga-枸橼酸而高于~(99m)Tc-PMT。9例肝良性病变均为阴性(一)。>5cm肝肿瘤~(99m)Tc-GH阳性率明显高于≤5cm者。AFP水平不同对~(99m)Tc-GH肝癌显像结果无影响。
Calcium glucoheptonate (GH) labeled with ~(99m)Tc (~(99m)Tc-GH) intravenously injects 370 to 740 MBq at 1~2h and 4~6h, and photographs the anterior, right and posterior segments of the liver. Bit image. The results found that 31 cases of hepatic malignant lesions (including metastatic carcinoma) were strongly positive in 17 cases, accounting for 54.8%; 6 cases were positive, accounting for 19.4%; the total positive rate was 74.2%. The positive rate was lower than ~(67)Ga-nonanoic acid and higher than ~(99m)Tc-PMT. Nine cases of benign hepatic lesions were negative (I). The positive rate of >5cm liver tumor ~(99m)Tc-GH was significantly higher than ≤5cm. Different levels of AFP had no effect on the results of ~(99m)Tc-GH liver cancer imaging.
