Radiologists tackle legal challenges and policies for evaluating outside studies

As more patients are referred to tertiary care center with previous images, a new study from researchers at the Westchester Medical Center shows how radiologists are tackling the challenges of interpreting outside studies and reviewing discordance opinions. "Outside studies were becoming a problem in our institution," said Dr. Zvi Lefkovitz, co-lead for this study. "We were receiving a lot of disjointed, fly-by-night examinations, and we had no formalized policy for reviewing these exams." Lefkovitz and his team began a comprehensive process of overhauling their procedures, ...

New standards for treating traumatic shoulder injuries improve patient care

Shoulder injuries are among the most frequently encountered musculoskeletal injuries treated in emergency departments. One new study shows how radiologists can more effectively identify these injuries and improve patient outcomes. "The severity of shoulder injuries are often underestimated," said Dr. Scott Sheehan, lead author for the study. "Subtle injuries can have significant consequences if not recognized and treated promptly." Sheehan and his co-authors began studying the effects of traumatic shoulder injuries after one of his radiology mentors suffered a shoulder ...

New imaging protocols help improve systemic functioning for living renal donors

A new study from UCLA shows how magnetic resonance angiography (MRA) and computed tomography angiography (CTA) are equivalent in delineating anatomy in living renal donors. In a study that examined 30 patients and 60 kidneys, both modalities were "excellent" in detecting the number of renal arteries and veins. Dr. Mittul Gulati, lead author for the study noted, "either MRA or CTA are great tools for helping surgeons remove kidneys safely, identifying donor and recipient veins and vessels, and identifying incidental findings." The results could potentially reduce radiation ...

Children neglected in clinical drug trials

BOSTON – Although children are more likely than adults to suffer from many diseases, few clinical trials are being conducted to test drugs in pediatric patients, according to a study to be presented Saturday, April 28, at the Pediatric Academic Societies (PAS) annual meeting in Boston. Drug studies in children are important because children often respond differently to medications than adults. However, there is widespread concern about the lack of clinical evidence available to guide physicians in prescribing pharmaceuticals to children. Florence Bourgeois, MD, MPH, ...

New standards for treating traumatic shoulder injuries to improve patient care

Traumatic shoulder injuries that result in a patient visit to the ER often contain a secondary injury that can cause pain and discomfort in that part of the body after the primary injury has healed. By focusing on the primary injury, radiologists sometimes miss the secondary injury, which can compromise treatment effectiveness. Trainees in the Brigham and Women's Hospital Radiology Residency Program developed new protocols aimed at drawing ER radiologists' attention to the potential presence of secondary should injuries. Better identification of these injuries could lead ...

Pacific islands may become refuge for corals in a warming climate, study finds

Scientists have predicted that ocean temperatures will rise in the equatorial Pacific by the end of the century, wreaking havoc on coral reef ecosystems. But a new study shows that climate change could cause ocean currents to operate in a surprising way and mitigate the warming near a handful of islands right on the equator. As a result these Pacific islands may become isolated refuges for corals and fish. Here's how it would happen, according to the study by Woods Hole Oceanographic Institution scientists Kristopher Karnauskas and Anne Cohen, published April 29 in the ...

Huge study finds brain networks connected to teen drug abuse

Why do some teenagers start smoking or experimenting with drugs—while others don't? In the largest imaging study of the human brain ever conducted—involving 1,896 14-year-olds—scientists have discovered a number of previously unknown networks that go a long way toward an answer. Robert Whelan and Hugh Garavan of the University of Vermont, along with a large group of international colleagues, report that differences in these networks provide strong evidence that some teenagers are at higher risk for drug and alcohol experimentation—simply because their brains work differently, ...
