To evaluate the use of spiral CT in the diagnosis of breast lesions.
93 female patients with suspicious or uncertain mammographic findings were examined by CT before and after contrast enhancement according to the following practical method: table movement, 6 mm/s, slice thickness 6 mm, increment 4 mm, contrast 200 ml, injection rate 3 ml/s, scan start 50 s after the beginning of the injection. Histological confirmation was present in 85 patients.
All 44 invasive carcinomas were recognised. They were characterised by intensive focal contrast uptake. Only 2 out of 7 intraductal carcinomas were not shown by CT. 36 out of 38 benign lesions were correctly diagnosed. 2 out of 11 fibroadenomas showed strong enhancement and were incorrectly diagnosed. The examinations provided valuable additional information compared to mammography and sonography.
Spiral CT is very useful for elucidating problems in the diagnosis of breast lesions. Its advantages consist in the speed of the method, comfort for the patient, absence of movement artifacts, easy standardisation and wide applicability.
评估螺旋CT在乳腺病变诊断中的应用。
93例乳腺钼靶检查结果可疑或不确定的女性患者，按照以下实际方法在增强扫描前后进行CT检查：检查床移动速度6mm/s，层厚6mm，层间距4mm，对比剂200ml，注射速率3ml/s，注射开始后50s开始扫描。85例患者有组织学确诊结果。
44例浸润性癌均被识别。其特征为局部对比剂强化明显。7例导管内癌中仅2例CT未显示。38例良性病变中36例被正确诊断。11例纤维腺瘤中有2例强化明显，诊断错误。与乳腺钼靶和超声检查相比，CT检查提供了有价值的额外信息。
螺旋CT对阐明乳腺病变诊断中的问题非常有用。其优点包括检查速度快、患者舒适度高、无运动伪影、易于标准化及广泛的适用性。
