Studies and Analyses

Medical procedures such as iodine therapy, a popular thyroid treatment, can result in patients triggering radiation detectors for up to three months after treatment, according to a study presented today at the annual meeting of the Radiological Society of North America (RSNA).

Diagnostic nuclear medicine procedures, including FDG PET scans, bone scans and cardiac scans, can have a similar effect, although for shorter periods. “The nuclear medicine community has been aware that p

As many as 28,000 patients die each year in the U.S. because of catheter-related bloodstream infections, but doctors and nurses who implement simple and inexpensive interventions can cut the number of deaths to nearly zero, according to a study by Johns Hopkins researchers.

“This type of improvement has never been demonstrated, but there is no reason that ICU’s across the country can’t implement these interventions to achieve similar results,” said Sean Berenholtz, M.D.

Study shows capacity exists to screen population within one year

More than 41 million Americans who are candidates for colorectal cancer screening have not been screened for this second-leading cancer killer, the first time the unscreened population has been quantified. According to a study published today in the American Gastroenterological Association (AGA) journal Gastroenterology, sufficient capacity exists to screen the unscreened population within one year using fecal occult b

Panoramic dental x-rays can be used to help identify postmenopausal women with low skeletal bone mineral density (BMD), meaning that screening for spinal osteoporosis could begin in the dentist’s office a new study shows.

The study included 316 postmenopausal women who had no symptoms of osteoporosis. The women were divided into two groups: 159 had no history of hysterectomy, oophorectomy or estrogen use, the remaining 157 had one or more of these histories. All had panor

In laboratory studies at Cincinnati Children’s Hospital Medical Center, researchers have successfully treated the most common malignant abdominal tumor of childhood: neuroblastoma tumors. Researchers successfully treated the tumor in mouse models by administering a treatment based on a weakened version of the herpes simplex virus.

The study appears in the current online issue of Pediatric Blood and Cancer, the journal of the American Society of Pediatric Hematology/Oncolo

When people lie, they use different parts of their brains than when they tell the truth, and these brain changes can be measured by functional magnetic resonance imaging (fMRI), according to a study presented today at the annual meeting of the Radiological Society of North America. The results suggest that fMRI may one day prove a more accurate lie detector than the polygraph.

“There may be unique areas in the brain involved in deception that can be measured with fMRI,” said
