DWI adds little to PET/MRI for female pelvic malignancies
CHICAGO - Adding diffusion-weighted imaging (DWI) to FDG-PET/MRI to stage women with primary or recurrent pelvic malignancies contributes minimal value and is not worth the additional scan time, according to a study from Germany presented on Sunday at RSNA 2014.

Payment cuts drive MRI to hospital outpatient setting
The number of MRI scans performed in hospital outpatient imaging departments has surpassed the amount performed in private offices. The change is due in part to reimbursement cuts that have made private-office MRI considerably less economically viable, according to a study published online November 15 in the Journal of the American College of Radiology.

MRI may hurt patients with cochlear implants
South Korean researchers are sending out a warning about the use of MRI in patients with cochlear implants after discovering that the strong electromagnetic field from 1.5- and 3-tesla scanners could cause pain and discomfort, as well as displacement of the cochlear implant magnet.

Images of a 39-year-old who underwent screening mammography. Right craniocaudal (left) and mediolateral oblique (middle) views from preoperative mammography show suspicious grouped fine pleomorphic calcifications (arrows). After biopsy showed ductal carcinoma of situ (DCIS), patient underwent breast-conserving surgery, yielding final diagnosis of ductal carcinoma in situ (intermediate grade, hormone receptor positive). (Right) Screenshot of an output of a commercial AI tool applied to preoperative mammography. AI detected right breast lesion with score of 95% on both views (concentric colored circles). Present study’s reviewing radiologist deemed AI marking to correspond with site of DCIS.

Could AI scoring help with managing DCIS?
Axial contrast-enhanced CT scan in a 28-year-old premenopausal woman shows an incidentally detected solid-appearing left ovarian lesion (solid arrow) anterior to the uterus (U), associated with trace ascites in the right adnexa and cul de sac (dashed arrows). At pathologic analysis, this was shown to be ovarian dysgerminoma. Two readers misdiagnosed this lesion, one as a leiomyoma and one as an ovarian fibroma.
