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

Ultrasound predicts spontaneous onset of labor and successful delivery in prolonged pregnancies

Wendy Despain

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



Ultrasound assessment of cervical length in first pregnancies past 41 weeks can serve as an independent predictor of the likelihood of spontaneous labor and successful vaginal delivery. Cervical length was shorter in women who experienced spontaneous onset… 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

Large screening mammography study restores faith in CAD

H. A. Abella

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



A new study based on nearly a quarter million mammograms suggests screening mammography with computer-aided detection is more sensitive than double reads. The findings contradict a key study published last year questioning its effectiveness.



CAD's potential for yielding too many false… Continue

Navigational MRI charts language map of brain

Larry Schuster

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



With help from navigational MRI, researchers at the University of California, San Francisco have assembled the largest composite map of the brain's language sites ever to appear in the medical literature. They found far greater variability in the location of these sites than other models of language… Continue

Reasons for computed or digital radiography vary, but both do the job

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

Most U.S. healthcare facilities have digital imaging technology in the form of either CR or DR. The decision is not when to go digital, but which technology is the most appropriate for each location.



Faced with limited budgets and space and other constraints, managers must… Continue

Ultrasound matches MRI and gold standard tests in detecting extent of Crohn’s disease

Wendy Despain

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



Color Doppler flow and sonographic wall thickness are as good as — and in some cases better than — contrast MRI for showing the extent of Crohn's disease. Both ultrasound and MRI match clinical results from barium studies, surgery, and colonoscopy.
