HL-91延迟显像在乳腺良恶性病变鉴别诊断中的价值

The Value of HL-91 Delay Imaging in the Diagnosis of the Breast Disease

目的:探讨HL 91延迟显像及半定量分析在乳腺癌诊断中的价值。方法:52例早期HL 91显像有 局灶性放射性增高的病人在注射显像剂6h后再进行延迟显像,根据延迟显像变化,病人分为两组:A组34例 延迟显像UR值变化不大,与早期显像UR值相比(P>0.05);B组18例延迟显像UR值明显降低或病灶消失, 与早期显像UR值相比(P<0.05)。两组病例进行随访。结果:经病理及临床最后证实A组均为乳腺癌,B组 均为良性病变。结论:延迟显像及半定量分析可提高乳腺良恶性病变诊断的准确性。

Objective:To explore the value of the HL-91 delayed imaging and semi-quantitave analysis method for the diagnosis of breast cancer. Methods:52 patients who had abnormal hypermetabolic foci for HL-91 early imaging underwent delayed image at 6 hours after injection. Patients were divided into two groups by the uptake ratio (UR) of L/N in the HL-91 delayed imaging. Group A(34 cases) included patients who had unchanged or increased UR value in the HL-91 delayed imaging as compared with early imaging. UR values of Group B(18 cases) decreased and were significant different with regard to their early imaging results(P<0.05).We followed up all of the patients by operation and pathology. Results:All of patients in group A were with breast cancer confiormed through biopsy, and were with benign diseases of the breast in group B. Conclusion:In the HL-91 scanning,the delayed image semi-quantitave analysis methods could improved the diagnostic accuracy greatly for the detection of breast neoplasms.
