目的分析139例乳腺癌影像表现和分型,旨在提高对本病诊断的准确性。方法回顾性观察139例经全数字化平板乳腺摄影(FFDM)检查、手术及病理证实的乳腺癌的X线表现和分型。结果139例乳腺癌中肿块结节型88例,单纯钙化型39例,局部结构紊乱型11例,导管阻塞型1例。肿块结节型中检测到小于1cm的微小癌和小癌16例。除导管阻塞型乳腺癌外其他各类型中均有钙化出现,钙化总显示率为80.57%,单纯钙化型乳腺癌的钙化分布、数目、密度和形态有别于其他类型。临床扪及包块的乳腺癌见于肿块结节型和局部结构紊乱型,未扪及包块乳腺癌仅见单纯钙化型和导管阻塞型。结论乳腺癌不同类型有其特有X线表现,FFDM对乳腺癌的影像表现显示清晰,对小病灶探测率高,显示小于0.1mm的微小钙化等有利于乳腺癌的诊断和分型。
Objective To analyze the imaging manifestations and classification of 139 cases of breast cancer so as to improve the accuracy of the diagnosis of this disease. Methods We retrospectively reviewed the X-ray findings and classification of 139 cases of breast cancer confirmed by surgery and pathology with digitalized flat-panel mammography (FFDM). Results Among 139 cases of breast cancer, 88 were nodular masses, 39 were calcified only, 11 were localized and 11 were ductal obstruction. Tumor nodules detected in less than 1cm of small and small cancerous 16 cases. In addition to duct obstruction type breast cancer in all other types of calcification appear, the total rate of calcification was 80.57%, simple calcification of calcification distribution, number, density and morphology are different from other types. Clinical palpable mass of breast cancer found in the mass of nodular and local structural disorders, palpable breast cancer was only seen with simple calcification and ductal obstruction. Conclusion Different types of breast cancer have their own characteristic X-ray manifestations, FFDM imaging of breast cancer showed a clear, high detection rate of small lesions, showed less than 0.1mm of tiny calcifications and other conducive to the diagnosis and classification of breast cancer.
