| 目的 比较不同定位方法99Tcm-PHY淋巴显像检测黑色素瘤前哨淋巴结(SLN)的价值。方法 回顾性纳入60例接受99Tcm-PHY淋巴显像的皮肤黑色素瘤患者,共标记65个SLN。分别采用SPECT/CT定位法和点源定位法进行体表标记;以病理结果为金标准,比较2种方法定位准确率。结果 SPECT/CT定位法总体准确率为96.92%(63/65),高于点源定位法的83.08%(54/65)(P＜0.05)。结论 SPECT/CT定位法检测黑色素瘤SLN总体准确率高于点源定位法。 |

| Objective To compare the value of 99Tcm-PHY lymphoscintigraphy with different localization methods for detecting sentinel lymph nodes (SLN) of melanoma. Methods A total of 60 patients with cutaneous melanoma who underwent 99Tcm-PHY lymphoscintigraphy were retrospectively enrolled, and 65 SLN were marked. SPECT/CT localization and radioactive point localization were used for body surface marking. Taken pathological results as the gold standards, the localization accuracy of the two methods were compared. Results The overall accuracy rate of SPECT/CT localization was 96.92% (63/65), higher than that of radioactive point localization (54/65, 83.08%) (P＜0.05). Conclusion The overall accuracy of SPECT/CT localization for detecting melanoma SLN was higher than that of radioactive point localization. |
