Studies establish primacy of uterine fibroid embolization for most patients

Sarah Jersild

--------------------------------------------------------------------------------



Two major studies have concluded that uterine artery embolization is as good as or better than hysterectomy for treatment of uterine fibroids. Embolization patients recovered faster and were hospitalized for less time than patients who underwent hysterectomy or myomectomy.… Continue

Lower cost ultrasound beats gold standard in assessment of psoriatic arthritis

Wendy Despain

--------------------------------------------------------------------------------

Standard musculoskeletal ultrasound is better than gold standard radiography at detecting overall joint pathology in the hands and feet of patients with psoriatic arthritis. MR imaging showed marginally better sensitivity at detecting joint effusions and synovitis, while… Continue

Cheap drug protects against CT contrast-induced nephropathy

H. A. Abella

--------------------------------------------------------------------------------



As the number of patients undergoing contrast-enhanced CT scans grows, so does the risk of contrast-induced nephropathy. What can physicians do to protect their patients from kidney damage? Ask them to pop an N-acetylcysteine pill before the exam, according to a study by University of Michigan… Continue

Sonographer experience translates into fewer unnecessary ovarian tumor surgeries

Allison Fromm

--------------------------------------------------------------------------------



Unnecessary surgeries for suspected, but ultimately benign, ovarian tumors could be reduced if ultrasonography is improved, according to a recent report in The Lancet Oncology. The study showed that the number of surgeries for suspected cancers was significantly higher… Continue

MRI detects occult breast cancer in Paget’s disease patients

Marjorie Preston

--------------------------------------------------------------------------------



Women with Paget's disease of the nipple can be more assured that MRI will detect otherwise hidden malignancies, leading to opportunities for breast conserving therapy, following research from the Memorial Sloan-Kettering Cancer Center in New York City.

Multiphoton microscope tracks plaques in mouse model

Don Rauf

--------------------------------------------------------------------------------



Long considered a sentinel factor for Alzheimer's disease, beta-amyloid proteins can accumulate in the brain in aggregations called senile plaques with amazing speed, affecting neurodegeneration just as readily, according to researchers at Harvard Medical School. Using in vivo multiphoton microscopy, Dr.… Continue

Concept of gaps helps bridge image retrieval divide

Douglas Page

--------------------------------------------------------------------------------

Promising new technologies such as content-based image retrieval can enrich medical informatics. Yet this technology is not well established in PACS, in spite of the advantages. The cause for this lag is usually attributed to its inability to bridge the divide between low-level computational pixel analysis… Continue
