TUMOR AND INFECTION LOCALIZATION IN AIDS PATIENTS - GA-67 AND TL-201 FINDINGS

Use of these methods is the adopted approach at this institution in AIDS pat ients for localizing sites of tumor or infection involvement. A Ga-67 scan is the most common nuclear medicine examination performed on AIDS patients. Sequential Tl-201 and Ga-67 scans have a role in differenti ating Kaposi's sarcoma from malignant lymphoma and opportunistic infec tions. For intracranial lesions, Tc-99m MIBI or Tl-201-201-201-201 chl oride can differentiate malignant from benign inflammatory lesions.
