Preop MRI reliable for soft-tissue necrosis in hip patients
By Wayne Forrest
Wednesday, November 28 | 11:00 a.m.-11:10 a.m. | SSK10-04 | Room E451APreoperative MRI using metal artifact suppression parameters can visualize extra-articular fluid collection, and is a reliable modality to show soft-tissue necrosis in patients presenting for additional surgery following primary total hip arthroplasty with metal-on-metal components, according to researchers from Massachusetts General Hospital.

DCE- and DWI-MRI show neoadjuvant chemotherapy results in breast cancer
By Wayne Forrest
Tuesday, November 27 | 11:10 a.m.-11:20 a.m. | SSG01-05 | Arie Crown TheaterBoth dynamic contrast-enhanced (DCE) and diffusion-weighted (DWI) MRI can accurately reflect response to neoadjuvant chemotherapy among breast cancer patients during treatment with minimum apparent diffusion coefficient (ADC) as the most predictive marker of pathologic response, according to a study to be presented on Tuesday.
