核素淋巴显像在血液病诊断中的临床应用

The clinical application of lymphoscintigraphy for the diagnosis in hematological diseases

报道了对７８例临床疑诊恶性淋巴瘤及白血病病人核素淋巴显像结果的分析，以评价淋巴显像在血液病诊断中的应用。经病理证实恶性淋巴瘤３０例，非恶性淋巴瘤２４例，核素淋巴显像诊断恶性淋巴瘤的灵敏度为８３．３％，特异性为６２．５％；与ＣＴ及Ｂ超相比，临床符合率分别为８３．３％、６６．７％和２２．２％；经骨髓穿刺证实白血病９例，非白血病１５例，核素显像诊断白血病的灵敏度为８８．９％，特异性为５３．３％；与ＣＴ相比，临床符合率分别为８８．９％和５０％。核素淋巴显像在恶性淋巴瘤以及白血病诊断方面有较高的灵敏度。

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.
