全数字化乳腺摄影对临床未触及肿块乳癌的诊断价值

目的　探讨全数字化乳腺摄影对临床未触及乳癌的诊断价值。方法　收集 2 0 0 3 -0 4～ 0 7门诊及体检 412例中遇到的 3 4例乳癌 ,其中临床触及肿块的 2 2例 ,未触及肿块的 12例。全部病例采用全数字化乳腺摄影机检查 ,并经病理证实 ,检查体位常规采用CC位 (头尾位 )、MLO位 (内外斜位 ) ,必要时加照侧位及局部点片。对临床未触及包块的乳癌 ,均行术前定位。结果　 2 2例临床触及肿块的乳癌中 ,髓样癌 4例 ,硬癌 2例 ,浸润性导管癌 16例。 12例临床未触及包块的乳癌中 ,X线呈现微小钙化 6例 ,其中癌前病变 1例、导管原位癌 2例、导管浸润性癌 3例 ;呈现微小结节 2例 ,其中 1例导管原位癌、1例导管浸润癌 ;呈现微小结节半结节内微小钙化 2例 ,1例导管原位癌、1例导管浸润癌 ;呈现结构紊乱区 1例 ,为小叶原位癌 ,结构紊乱区伴微小钙化 1例 ,为浸润导管癌。结论　全数字化乳腺摄影能清晰显示乳腺癌的直接及间接征象 ,尤其对临床未触及包块的乳癌具有更重要的诊断价值

Diagnostic Evaluation of Full-field Digital Mammography for Nonpalpable Breast Cancer

Objective To evaluate the clinical significance of full-field digital mammography(FFDM) for nonpalpabal breast cancer.Methods 34 cases breast cancer(palpable breast cancer 22 cases,nonpalpable breast cancer 12 cases) were all examined using FFDM and all cases were proved by pathology.Craniocaudal(CC) view and mediolateral oblique(MLO) view were conducted for every patient. Mediolateral view or spot view was achieved if necessary. Preoperative localization was conducted for every patient with nonpalpable breast cancers.Results There were five X-ray findings for 12 cases with non palpable breast cancers in our group: microcalcification 6 cases; nodule 2 cases; nodule with microcalcification 2 cases; architectual distortion 1 case; architectual with microcalcification 1 case.Conclusion FFDM has very important evaluation for nonpalpable breast cancers.
