用体部ＣＴ对７５例乳房肿块进行了检查，其中４２例为乳癌。增强扫描癌灶有显著增强，绝大部分病例比平扫ＣＴ值增加３０ＨＵ以上，因此可显示常规Ｘ线摄影中未显示出的或与周围乳腺增生病变不能分辨的癌灶。本组乳癌ＣＴ诊断的敏感性９５．２４％，特异性８９．３９％，准确率９２．６６％，与干板摄影互补准确率达９６％。讨论了乳癌ＣＴ检查的鉴别诊断及其难点。作者认为ＣＴ扫描可补常规乳房Ｘ线摄影之不足。
Twenty-five breast lumps were examined by body CT, of which 42 were breast cancers. The enhanced scanning foci are significantly enhanced, and most cases are more than 30 HU higher than the CT value of the plain CT scan. Therefore, they can show foci that are not shown in conventional radiographs or are indistinguishable from surrounding breast hyperplasia. In this group, the sensitivity of CT diagnosis of breast cancer was 95.24%, specificity was 89.39%, accuracy was 92.66%, and the complementary accuracy with dry plate photography was 96%. The differential diagnosis and difficulties of CT examination of breast cancer were discussed. The authors believe that CT scans can compensate for the lack of conventional mammography.
