Technetium-99m tetrofosmin scintigraphy for detecting malignant lymphoma

The aim of this study was to assess the use of Tc-99m tetrofosmin (Tc-TF) scintigraphy for detecting malignant lymphomas. In the study, before any chemotherapy, 50 patients with malignant lymphoma underwent Tc-TF scintigraphy, which was performed 10 minutes after intravenous injection of 20 mCt Tc-TF. Tc-TF scintigraphy detected malignant lymphoma in 44 (88%) patients. However, there were no significant differences in the incidences of positive and negative Tc-TF scintigraphic results between female versus male patients, HD versus NHL patients, stage I-II versus stage III-IV patients, age > 40 years versus < or = 40 years patients and patients with B symptoms false-negative results occurred in 4 (8%) infradiaphragmatic malignant lymphoma. We conclude patients with that Tc-TF scintigraphy appears suitable for detecting malignant lymphoma, especially supradiaphragmatic lesions.
