Inversion-recovery MRI falls short in brain tumor detection
Inversion-recovery (IR) imaging has made significant strides in brain MR, offering higher T1-weighted contrast and improving the contrast ratio of tumor to white matter. But IR imaging still cannot best spin-echo (SE) MRI for detecting brain metastases, according to radiologists from China. They compared the two MR protocols in 31 patients treated at the First Affiliated Hospital of Anhui Medical University in Hefei.

Multimodality studies tackle benign but evasive nerve-sheath tumors
Separating neurofibromas from schwannomas, also known as neurilemomas, is crucial in guiding surgical resection. Historically, diagnosis has been achieved clinically and with biopsy. But making the all-important differential diagnosis isn't easy with either approach. Which imaging modality is up to the task? Musculoskeletal experts in Taiwan explored the role of ultrasound, while a group from the U.S. laid out the imaging appearance of these nerve-sheath tumors.

MR study reveals 'novel' findings on whiplash pathophysiology
Two years ago physical therapist James Elliott, Ph.D., and his co-authors conducted a study that pinpointed a connection between the chronic pain associated with whiplash and MR signs of fatty infiltrate in the cervical extensor muscles. In their latest work, they investigated the presence of fatty infiltrate in patients with nonwhiplash-related neck pain, and found that not all chronic neck pain is created equal.

Disease-free survival, mortality uphold novel radiotherapies for prostate cancer
Prostate cancer research is abuzz with advances in both diagnosis and treatment. Proposed diagnostic tools include a vaccine and a urine-based test that may beat the prostate-specific antigen gold standard. Meanwhile, treatment methods range from high-dose radiation alone to combining radiotherapy with hormone therapy. Two recent papers offer updates from long-term, randomized trials.

Missed turn: What makes MRI detour in diagnosing meniscal tears?
On the whole, MR imaging negotiates the twists and turns of the knees with the greatest of ease. But there is one type of injury where MRI often hits a roadblock: meniscal tears. A recent study by researchers at the Madison-based University of Wisconsin School of Medicine and Public Health took a closer look at why these tears are sometimes missed at MRI, and whether certain clinical factors are in the modality's blind spot.

Ultrasound shows promise as a screening tool for wrist pain
More than 2.2 million people in the U.S. turn up at their doctor's office with complaints of wrist pain, but ordering up costly MRI and MR arthrography exams -- or radiation-laden CT arthrography -- is not always feasible. Orthopedic specialists from Tucson's University of Arizona have proposed ultrasound-based exams as a screening tool for wrist ligaments.

Total tumor biology impacts cervical cancer regression during EBRT
Cervical tumor volume may be an insufficient marker for changes during fractionated radiotherapy, according to a study in the January issue of the International Journal of Radiation Oncology, Biology, Physics. Instead, researchers from Toronto have developed a multivariate strategy to better predict tumor response during treatment.

Examples in two patients. (Top) Abnormal leukocyte accumulation was observed in the right 1st to 5th toes, with the radioactive lesions extending to the bone, indicating osteomyelitis (left panel, MIP image; right panel, axial SPECT/CT). Two spherical VOIs were drawn on diabetic foot infections (DFIs) and the highest SUVmax was 4.2 (higher than the cutoff of 1.1) Despite intensive treatment, the infection progressed, leading to the patient undergoing right below knee amputation 43 days after SPECT/CT. (Bottom) Mild focal abnormal leukocyte accumulation was detected in the right 3rd and 4th toes. The lesions were in contact with the bone, which raised a suspicion of osteomyelitis (left panel, MIP image; right panel, axial SPECT/CT). A circular VOI was drawn on DFIs and the SUVmax was 1.0 (lower than the cutoff of 1.1). After 10 weeks of antibiotic treatment, the infection was successfully resolved, and the foot was preserved.
