Researchers visualize ruptures of atherosclerotic plaques with multi-color CT and gold nanoparticles

Researchers from Mount Sinai School of Medicine have for the first time developed a way to visualize coronary artery plaques vulnerable to rupture using multi-color computed tomography (CT), an innovation that will lead to better and earlier diagnosis of cardiovascular disease. The data are published in the September issue of Radiology.

Scientists develop new imaging technique to create three-dimensional images of melanoma

Melanoma is one of the less common types of skin cancer but it accounts for the majority of the skin cancer deaths (about 75 percent).The five-year survival rate for early stage melanoma is very high (98 percent), but the rate drops precipitously if the cancer is detected late or there is recurrence.So a great deal rides on the accuracy of the initial surgery, where the goal is to remove as little tissue as possible while obtaining "clean margins" all around the tumor.So far no imaging technique has been up to the task of defining the melanoma's boundaries accurately enough to guide surgery.Instead surgeons tend to cut well beyond the visible margins of the lesion in order to be certain they remove all the malignant tissue.Two scientists at Washington University in St. Louis have developed technologies that together promise to solve this difficult problem.

Hybrid scanner helps to enhance visibility of skin cancer cells

Scientists are reporting development of a substance to enhance the visibility of skin cancer cells during scans with an advanced medical imaging system that combines ultrasound and light. The hybrid scanner could enable doctors to detect melanoma, the most serious form of skin cancer, in its earliest and most curable stages, the report in the monthly journal ACS Nano indicates.

Scientists identify chemical system effective in cocaine-addiction cure

UT Southwestern Medical Center researchers have identified a chemical system in the brain that reacts differently in cocaine addicts, findings that could result in new treatment options for individuals addicted to the drug."We found that the amount of blood flow in areas of the brain known to be involved in the rewarding effects of cocaine and craving was different in cocaine addicts, compared with healthy subjects," said Dr. Bryon Adinoff, professor of psychiatry at UT Southwestern and lead author of a study that appeared in Neuropsychopharmacology. "Now we have a new target for pharmacologic intervention."

Vena cava blood clot filters may cause potential life-threatening complications: Study

Two specific types of vena cava filters, devices used to prevent blood clots from reaching the lungs, appear to have evidence of fracturing inside the body, with some fractured fragments traveling to the heart and causing potentially life-threatening complications, according to a report posted online today that will appear in the November 8 print issue of Archives of Internal Medicine, one of the JAMA/Archives journals.

New perfusion CT algorithms maintain image quality at half of the radiation dose

In recent years, advances in CT scanner technology have made perfusion computed tomography (CT) imaging an important diagnostic tool for patients with suspected stroke. Now, researchers at Mayo Clinic are working to reduce radiation dosages used to acquire perfusion and other CT images. Mayo Clinic medical physicist Cynthia McCollough, Ph.D., and her group of researchers presented their findings related to CT dose reduction at the 52nd Annual Meeting of the American Association of Physicists in Medicine on July 20 in Philadelphia.
