- Abstract
Background: Diffusion Weighted Imaging with Back-ground Suppression is a new technique which uses the same concept of diffusion weighted imaging yet has the privilege of back-ground suppression and acquisition at a wider range of b-values hence increasing sensitivity and specificity. Objective: to determine the accuracy of DWIBS MR imaging in comparison to the DEC MR imaging in characterizing suspicious mammography lesions. Patients and Methods: twenty patients were included in the study, all with suspicious breast lesions from Ain-Shams University mammography clinic. A cross-sectional study was held where all the patients under-went MRI breast protocol which included DCE and DWIBS sequences. The MRI of all the patients was read by two expert radiologists blinded to each other's opinion. Biopsy was then done for histopathological correlation. The results were statistically analyzed. Results: seventy percent of the patients included in our study had malignant lesions and 30% had benign lesions. Both DWIBS and DCE showed comparable efficacy of 90% and 95% respectively. Conclusion: DWIBS can be used as an adjunct to DCE breast MRI improving its sensitivity and specificity. It can as well be used instead of DCE sequences in cases of renal impairment.
