目的探讨X射线位相成像(Phase contrast mammography system,PCM)对乳腺肿瘤的诊断价值,提高对乳腺肿瘤的诊断水平。方法回顾性分析经手术病理证实的117例乳腺肿瘤的X射线位相成像征象特点,其中良性肿瘤52例,乳腺癌65例。结果乳腺良性肿瘤多表现为圆形、椭圆形肿块,边界清楚,周边有或无透明“晕征”。导管内乳头状瘤乳管造影多表现为导管单个或多个充盈缺损,边缘光滑。65例乳腺癌表现为肿块者56例(86%),微钙化25例(38%),肿块伴微钙化18例(28%),局限致密影5例(8%)。结论 X射线位相成像可以清晰地显示乳腺肿瘤的病变结构,对乳腺肿瘤有重要的诊断价值。
Objective To investigate the diagnostic value of phase contrast mammography system (PCM) in breast neoplasms and to improve the diagnosis of breast neoplasms. Methods Retrospective analysis of 117 cases of breast tumors confirmed by surgery and pathology X-ray imaging features, including benign tumors in 52 cases, 65 cases of breast cancer. The results of benign breast tumors showed mostly round, oval-shaped mass, the border is clear, with or without the surrounding transparent “halo sign ”. Intraductal papilloma Ductal angiography manifested as single or multiple catheter filling defect, smooth edges. Of the 65 breast cancers, 56 (86%) showed mass, 25 (38%) were microcalcifications, 18 (28%) were associated with microcalcifications and 5 (8%) were localized densifilm. Conclusion X-ray phase imaging can clearly show the pathological changes of breast neoplasms and have important diagnostic value for breast neoplasms.
