PET-CT is better for early detection of muscular lymphoma than CT alone

For the study, PET-CT was used to image 305 patients with lymphoma. Twelve of these patients had muscular involvement in which 10 were biopsy proven and two were proven by imaging follow-up.

New option for soft-tissue imaging in interventional radiology procedures

Soft-tissue cross-sectional imaging acquired on a flat panel C-arm fluoroscopic unit located in the interventional radiology area is feasible and useful for interventional radiology procedures, avoiding the necessity of sending patients out to a CT scanner, according to a new study by researchers from the Baptist Cardiac & Vascular Institute in Miami, FL.

MR imaging helps predict recurrence in prostate cancer patients

MR images taken of prostate cancer patients prior to treatment that show that the cancer has spread outside the prostate gland capsule help predict whether the cancer will return, according to a recent study conducted by radiologists at the University of California-San Francisco.

Multitasking mental cells

In the mid-1990s, scientists at the University of Parma, in Italy, made a discovery so novel that it shifted the way psychologists discuss the brain. After researchers implanted electrodes into the heads of monkeys, they noticed a burst of activity in the premotor cortex when the animals clutched a piece of food.

MDCT eliminates need for catheter angiography for aortic injury diagnosis

Contrast-enhanced 64-MDCT that definitively reveals acute trauma to the aorta does not need confirmation from invasive catheter angiography, which saves valuable time in treating patients in trauma centers, according to a new study by researchers from the Medical University of South Carolina in Charleston.

Intense trauma can have long lasting effects on the brain and behavior of healthy people without causing a clinical disorder

Exposure to trauma may create enough changes in the brain to sensitize people to overreact to an innocuous facial gesture years later, even in people who don't have a stress-related disorder, says new research.

Computer-aided detection with computed radiography is effective in the detection of breast cancer

The study included 53 cases with breast cancer that were evaluated using a CAD system. The researchers assessed the sensitivity of cancer detection by CAD, and the mammmographic density as well as cancer sizes.
