It can change the treatment plan in 15-30% of patients with breast cancer. We will discuss the interpretation of breast MRI by looking at: The morphology of a lesion; T1- and T2- . The differences between enhancing and nonenhancing lesions in MRI are obvious. Normally with T1 contrast agents at a usual dosage, the enhancing lesions appear hyperintense on MR images and.
In contrast enhanced breast MRI, lesion detection is usually easy due to the cross-sectional image acquisition and the high contrast between the enhancing lesions and the non- or delayed enhancing background. What requires substantial expertise and personal experience, however, is the. To determine that an enhancing lesion is actually a nipple, viewing the anatomic image without contrast injection, comparing with the other side and performing three-dimensional reformatting can be helpful.
