Abstract
99mTc-Dextran (99mTc-D) was evaluated as an iliopelvic lymphoscintigraphic agent in 49 patients with malignant lymphoma and the results were compared with ultrasound (US), lymphangiography (LA) and CT where available. Scintigrams were obtained by a gamma camera at 2 h postinjection and evaluated by comparing opposite sides. In 29 of 49 patients, normal lymphoscintigrams of excellent quality, deliniating the iliopelvic and paraaortic lymph nodes bilaterally were obtained. In 20 patients lymphoscintigraphy (LS) was positive. US was performed in 46 patients, 20 had positive and 26 negative findings. There was one false positive and one false negative in LS compared to US. Ten patients had LA and 3 had CT. These results were in complete agreement with LS. There was also a positive correlation between the clinical stages and the results of LS. This study showed that99mTc-D is an excellent radiopharmaceutical for the visualization of the lymph system with high correlation with other imaging modalities.
