Abstract

PURPOSE: To assess whether rotating delivery of excitation off resonance (RODEO) breast magnetic resonance (MR) imaging can help detect ductal carinoma in situ (DCIS) lesions, determine tumor extent, and differentiate pure DCIS from DCIS with an invasive component. MATERIALS AND METHODS: Twenty-two patients with DCIS lesions were evaluated with three-dimensional RODEO MR imaging. Nineteen patients had available mammograms for review. RESULTS: MR imaging enabled detection of all 22 cases of DCIS, DCIS with microinvasion, or invasive ductal carcinoma with extensive intraductal component. A clumped enhancement pattern was seen on MR images in all cases of pure DCIS. Spiculated enhancement was seen in four of six (67%) patients who had DCIS with microinvasion and in nine of 11 (82%) who had invasive ductal carcinoma with extensive intraductal component. RODEO MR imaging enabled accurate determination of tumor extent in 21 of 22 (95%) patients. Mammography depicted 18 of 19 DCIS lesions. No mammographic feature helped differentiate pure DCIS from DCIS with microinvasion. Mammography enabled accurate determination of tumor extent in 14 of 19 (74%) patients. CONCLUSION: Three-dimensional RODEO MR imaging can be an adjunct to mammography because of its ability to enable better determination of tumor extent and differentiation of pure DCIS from DCIS with an invasive component.
