^(67)Ga显像对活动性肺结核的诊断价值

The diadynamic value of 67 gallium scintigraphy of active pulmonary tuberculosis

目的 探讨 6 7Ga显像对活动性肺结核的诊断价值。方法 对 16 0例非肿瘤患者 6 7Ga显像结果进行回顾性分析 ,诊断活动性肺结核 10 0例 ;陈旧性肺结核 2 6例 ;普通肺炎 2 9例 ;淋巴结核 5例。结果 活动性肺结核患者 6 7Ga阳性显像率 72 .0 0 % (72 /10 0 ) ,明显高于陈旧性肺结核 2 3.0 8% (6 / 2 6 )及普通肺炎 17.2 4 % (5 / 2 9) ,活动性肺结核患者中 ,痰菌阳性患者 6 7Ga阳性显像率 79.73% (5 9/ 74 ) ,明显高于痰菌阴性者 5 0 .0 0 % (13/ 2 6 )。结论 6 7Ga显像可能在判断肺结核活动性中具有一定价值。

Objective To evaluate the the diadynamic value of 67 gallium scintigraphy of active pulmonary tuberculosis.Methods Retrospective analysis was used at 160 non tumour patiens of 67 gallium scintigraphy, including 100 active pulmonary tuberculosis, 26 oboslete tuberculosis, 29 pneumonia and 5 tuberculous lymphadenitis. Results The positive scanning rate of active pulmonary tuberculosis was 72.00%, and was significantly higher than that of inactive pulmonary tuberculosis 23.08%(6/26)and pneumonia 17.24%(5/29) In patients of active pulmonary tuberculosis, the positive 67 Ga scanning rate of smear positive patients 79.73% (59/74)was significantly higher than that of smear negative patients 50.00%(13/26). Conclusion 67 Ga scans may be useful in determining the degree of activity of pulmonary tuberculosis.
