Results of lymphoscintigraphy in 78 patients with clinically suspected malignant lymphoma and leukemia were reported and its clinical value for in diagnosis of hematological diseases were evaluated. Confirmed by pathological examination

30 cases were diagnosed as malignant lymphoma and 24 cases non-malignant lymphoma. In malignant lymphoma

the sensitivity of lymphoscintigraphy was 83.3% and the specificity 62.5%

where the sensitivity of CT and ultrasound

were 83.3%

66.7% and 22.2% respectively. Confirmed by bone marrow biopsy

leukemia was found in 9 cases and non-leukemia in 15. In leukemia

the sensitivity of lymphoscintigraphy was 88.9% and specificity 53.3%. Whereas the sensitivity of CT

was 50%. Therefore

the lymphoscintigraphy have comparatively high sensitivity for the diagnosis of malignant lymphoma and leukemia.
