CHICAGO—According to a study presented today at the annual meeting of the Radiological Society of North America (RSNA), the best way to detect cocaine in the body of a human drug courier, known as a mule, is through the use of CT.
"Cocaine from South America is making its way to Europe through Africa," said Patricia Flach, M.D., a radiologist at University Hospital of Berne and Institute of Forensic Medicine of Berne in Switzerland. "From Africa, drug mules most commonly try to enter the European Union and Switzerland.

People With Sleep Apnea at Higher Risk for Aggressive Heart Disease
CHICAGO—People with obstructive sleep apnea (OSA), a sleep disorder associated with obesity, have more non-calcified or "bad" plaque in their coronary arteries, according to a study presented today at the annual meeting of the Radiological Society of North America (RSNA).
"Our study reveals that individuals with obstructive sleep apnea are prone to developing an aggressive form of atherosclerosis that puts them at risk for impaired blood flow and cardiovascular events," said U. Joseph Schoepf, M.D., professor of radiology and medicine and director of cardiovascular imaging at the Medical University of South Carolina in Charleston, S.C.

New Study Reports Effects of Endurance Running
CHICAGO—Using a mobile MRI unit, researchers followed runners for two months along a 4,500-kilometer course to study how their bodies responded to the high-stress conditions of an ultra-long-distance race, according to a study presented today at the annual meeting of the Radiological Society of North America (RSNA).
"Due to the exceptional setting of this study, we could acquire huge amounts of unique data regarding how endurance running affects the body's muscle and body fat," said Uwe Schütz, M.D., a specialist in orthopedics and trauma surgery in the department of diagnostic and interventional radiology at the University Hospital of Ulm in Germany. "Much of what we have learned so far can also be applied to the average runner."

Annual Breast Cancer Screening Beginning at Age 40 Reduces Mastectomy Risk
CHICAGO—Having a yearly mammogram greatly reduces the risk of mastectomy following breast cancer in women between the ages of 40 and 50, according to a study being presented today at the annual meeting of the Radiological Society of North America (RSNA).
"The results of this study support the importance of regular screening in the 40 to 50 age group," said lead author Nicholas M. Perry, M.B.B.S., F.R.C.S., F.R.C.R., director of The London Breast Institute at The Princess Grace Hospital in London. "Women in this age group who had undergone mammography the previous year had a mastectomy rate of less than half that of the others."

Belly Fat Puts Women at Risk for Osteoporosis
CHICAGO—For years, it was believed that obese women were at lower risk for developing osteoporosis, and that excess body fat actually protected against bone loss. However, a study presented today at the annual meeting of the Radiological Society of North America (RSNA) found that having too much internal abdominal fat may, in fact, have a damaging effect on bone health.
"We know that obesity is a major public health problem," said the study's lead author, Miriam A. Bredella, M.D., a radiologist at Massachusetts General Hospital and assistant professor of radiology at Harvard Medical School in Boston. "Now we know that abdominal obesity needs to be included as a risk factor for osteoporosis and bone loss."

Diagnosis Uncertainty Increases Anxiety in Patients…
CHICAGO—Have you ever felt uneasy sitting in a doctor's waiting room or climbed the walls waiting for your test results? That feeling of anxious uncertainty can be more stressful than knowing you have a serious illness, according to a study presented today at the annual meeting of the Radiological Society of North America (RSNA).
"Not knowing your diagnosis is a very serious stressor," said the study's lead author, Elvira V. Lang, M.D., associate professor of radiology at Harvard Medical School in Boston. "It can be as serious as knowing that you have malignant disease or need to undergo a possibly risky treatment."

Virtual Biopsy May Allow Earlier Diagnosis of Brain Disorder in Athletes
CHICAGO—In a study of retired professional athletes, researchers found that a specialized imaging technique called magnetic resonance spectroscopy (MRS) may help diagnose chronic traumatic encephalopathy (CTE), a disorder caused by repetitive head trauma that currently can only be definitively diagnosed at autopsy. Results of the study were presented today at the annual meeting of the Radiological Society of North America (RSNA).
"The devastating effects of brain injuries suffered by professional football players who repeatedly suffered concussions and sub-concussive brain trauma during their careers have put the spotlight on CTE," said Alexander P. Lin, Ph.D., a principal investigator at the Center for Clinical Spectroscopy at Brigham and Women's Hospital in Boston. "However, blows to the head suffered by all athletes involved in contact sports are of increasing concern."

Acupuncture Changes Brain's Perception and Processing of Pain
CHICAGO—Using functional magnetic resonance imaging (fMRI), researchers have captured pictures of the brain while patients experienced a pain stimulus—with and without acupuncture—to determine acupuncture's effect on how the brain processes pain. Results of the study, which the researchers say suggest the effectiveness of acupuncture, were presented today at the annual meeting of the Radiological Society of North America (RSNA).
"Until now, the role of acupuncture in the perception and processing of pain has been controversial," said lead researcher Nina Theysohn, M.D., from the department of diagnostic and interventional radiology and neuroradiology at University Hospital in Essen, Germany. "Functional MRI gives us the opportunity to directly observe areas of the brain that are activated during pain perception and see the variances that occur with acupuncture." fMRI measures tiny metabolic changes that take place in an active part of the brain, while a patient performs a task or is exposed to a specific external stimulus.
