Technetium-99m tetrofosmin scintigraphy for detecting malignant lymphoma

The aim of this study was to assess the use of Tc-99m tetrofosmin (Tc-TF) s cintigraphy for detecting malignant lymphomas. In the study, before any che motherapy, 50 patients with malignant lymphoma underwent Tc-TF scintigraphy , which was performed 10 minutes after intravenous injection of 20 mCt Tc-T F Tc-TF scintigraphy detected malignant lymphoma in 44 (88%) patients. Howe ver, there were no significant differences in the incidences of positive an d 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 less than or equal to 40 years patients and patients with B sy mptoms false-negative results occured in 4 (8%) infradiaphragmatic malignan t lymphoma. We conclude patients with that Tc-TF scintigraphy appears suita ble for detecting malignant lymphoma, especially supradiaphragmatic lesions .
