Presence of osteoarthritis influences bone bruise prognosis
By Shalmali Pal
Bone bruises are thought to result from microfractures of the medullar trabeculae. They are often radiographically occult and hidden on arthroscopy. In a new paper in the September issue of American Journal of Roentgenology, Dutch radiologists looked at whether the natural course of bone bruises, as seen on MRI, had any prognostic value.

Fused MRI and PET improve specificity of breast MRI
By Wayne Forrest
Researchers at New York University's School of Medicine have found that the combination of functional information from F-18 FDG-PET and anatomic localization from MR imaging can provide a valuable diagnostic method for the detection of primary and recurrent breast cancer. The study noted that fused PET and MRI images substantially increased the specificity of MRI, but, at the same time, decreased MRI's sensitivity in the group of patients analyzed.

Presence of invasive cancer may cause MR-guided biopsy to miss DCIS
By Shalmali Pal
MRI-guided vacuum-assisted breast biopsy has been deemed safe, fast, and accurate for evaluating MRI-detected lesions, but the procedure may fail to completely characterize the target lesion, even when a 9-gauge device is used, according to a group from Memorial-Sloan Kettering Cancer Center (MSKCC), who assessed the underestimation rate of ductal carcinoma in situ (DCIS) with MR biopsy.

Case study: Acute avulsion fracture of ischial tuberosity in adolescent soccer player
Avulsion fractures of the ischial tuberosity are associated with forceful flexion of the hip (usually with the knee extended). This injury is easily misdiagnosed due to similar presentation to other injuries involving the hamstrings. Medical student Adam Sharp and Dr. Douglas Beall share their experience with this common injury in young athletes.

Total process management for efficient MRI suites
By Tobias Gilk
Today, financial pressures are compelling diagnostic imaging facilities to maximize referrals and squeeze more patients in and out of the scanner in a limited time period. Simultaneously, MRI safety is a major concern with organizations like the American College of Radiology releasing new guidance on MRI safety. These recommendations insist on changes that may not be anticipated. In order to comply, which do you choose: throughput or safety? And is a third option -- both -- a realistic one? The experts from MRIPlanning.com offer some answers to these questions.

MRI beats US for breast screening of at-risk women, but yields more biopsies
By Shalmali Pal
A new study in Radiology has found that MRI beats ultrasound when used as a complement to mammography in monitoring women at high risk of developing breast cancer. The study adds further weight to arguments that MRI should play a major role as an adjunct in screening high-risk women.

MRI depicts small lesions, predicts malignancy in lung cancer
By Shalmali Pal
CT plays a major role in lung cancer imaging, with support from molecular imaging, sonography, and angiography. MRI also contributes to a greater understanding of small nodules, particularly with the recent introduction of improved protocols. Two new studies suggest that dynamic MRI and 3-tesla MRI can depict clinically significant small nodules, and also distinguish between benign and malignant lesions. In a related paper, Japanese nuclear medicine specialists looked at the value of MR for assessing cerebral lesions from metastatic lung cancer.
