Imaging findings OR Procedure details

•It is important for the general radiologist to be familiar with indications and contraindications, equipment and patient positioning, imaging basics, the ACR BI-RADS® lexicon, common artifacts, common lesions, post-treatment evaluation, and silicone implant evaluation.

•With a focus on the basic imaging principles of breast MRI rather than on mathematical equations, this exhibit will show a practical approach to imaging protocols that helps radiologists increase their diagnostic effectiveness.

MRI protocol was standardized in all cases. Diagnostic enhanced breast MRI was performed at 1.5T and 3.0T clinical MR imaging system by using a bilateral, dedicated phased-array 8-Channel Breast Array breast coil with the patient in the prone position. The protocol included an axial localizer sequence followed by sagittal and axial fast spin-echo T2 and T1-weighted and STIR sequences. This was followed by Multifunctional sequences, which included DWI, SWI, IDEAL, dynamic contrast enhanced MRI and Spectroscopy.
