摘要：

Purpose: To define the value of contrast-enhanced MR mammography in ductal carcinoma in situ (DCIS). Material and methods: In a group of 35 patients with DCIS, the results of MR imaging were compared to histopathology and immunohistochemistry in a retrospective study. Results: In 35 patients with DCIS, a signal enhancement was found in 25 cases (72 %). In 15 of these cases,the signal time curve was typical for malignancy. The other 10 patients had non-specific signal curves. Six of 35 patients (11 %) had no enhancement within the tumour region. Four of 35 patients (11 %) had bilateral diffuse signal increase, and regions of DCIS could not be identified clearly. Three DCIS were visualised exclusively by MR mammography. The configuration of signal enhancement was sharp (32 %), unsharp (48 %) or dendritic (20 %). DCIS of the comedo type showed a significantly higher enhancement than the non-comedo type. A significant correlation between the grade of vascularisation in immunohistochemistry and signal enhancement in MR mammography could not be demonstrated. Conclusion: Dynamic MR mammography does not reliably visualise DCIS.
