计算机摄影钼靶检查在乳腺癌普查中的应用

目的:探讨计算机摄影(CR)钼靶检查在大规模乳腺疾病普查中的应用价值,提高早期乳腺癌的诊断水平。方法:应用钼铑双靶乳腺机和带有计算机辅助诊断(CAD)软件的CR系统,对8270例普查对象进行乳腺摄影检查,回顾性分析检查结果,其中有手术或病理活检结果的414例。结果:手术或病理活检证实的414例中,乳腺癌59例,其中临床触诊阴性的早期乳腺癌19例。早期乳腺癌主要X线表现为单纯簇状细微钙化、小结节、局部结构不良和小斑片状致密影。结论:乳腺CR钼靶摄影结合CAD是较为可靠的影像学方法,对早期乳腺癌的诊断有价值,可以应用于大规模乳腺疾病普查中。

Application of computed radiography molybdenum target detection in census of breast cancer

【Abstract】 Objective To exploring about CR molybdenum target detection’s application value in large scale census of mammary gland’s desease, elevate earlier period diagnose level of breast cancer. Methods To used molybdenum and rhodium twin target breast X-ray radiography and CR system with computer aided detection（CAD) software, make use of breast X-ray radiography to detection of 8270 census target, retrospective analysis detection result, four hundreds fourteen examples have been confirmed by operation and pathology. Results fifty nine examples are breast cancer in the four hundreds fourteen examples, among the total have nineteen examples earlier period breast cancer which clinical palpation is negative. The main X-ray appearance of earlier period breast cancer are Simple Tuft and Calcification、tuberculum minus、region dysplasia and little patching pykno- shadow. Conclusions mammary gland CR molybdenum target photograph association CAD is a dependable imageology method, it’s very worthiness in earlier period diagnose of breast cancer, and that can application in large scale census of mammary gland’s desease.
