| Abstract | PURPOSE: To evaluate the clinical usefulness of dynamic multidetector-row CT (dynamic MD-CT) for the detection of intraductal extension of breast cancer. MATERIALS AND METHODS: Dynamic MD-CT was performed in 31 patients with breast masses (26 invasive ductal carcinomas, 4 non-invasive ductal carcinomas and one benign lesion). We grouped the cases into four categories according to the degree of intraductal extension of the main tumor: IDS1: intraductal component less than 1 cm, IDS2: intraductal component 1 cm to 2 cm, IDS3: intraductal component 2 cm to 3 cm, IDS4: intraductal component more than 3 cm. To achieve complete CT-pathologic correlation, we retrospectively reconstructed MPR in the same plane as the histological cross-section. RESULTS: Thirty breast carcinomas (100%) showed strong enhancement in both the first and second phases of contrast enhanced dynamic MD-CT. The sensitivity and specificity of dynamic MD-CT for the detection of the intraductal component were 80.0% (12/15) and 100% (15/15). The accuracy of detection for the four tumor categories was 100% (15/15) for IDS1, 25% (1/4) for IDS2, 42.9% (3/7) for IDS3, and 100% (4/4) for IDS4. CONCLUSION: Dynamic MD-CT of the breast was found to be effective for the detection of intraductal extension of breast carcinoma and thought to be useful in the preoperative assessment of indications of breast-conserving surgery. |
