Mending broken hearts

The causes of "broken heart syndrome" remain a mystery, but doctors will soon have an easier time recognizing and treating this rare, life-threatening condition, thanks to data being reported at the 30th Annual Scientific Sessions of the Society for Cardiovascular Angiography and Interventions (SCAI), May 9-12, 2007, in Orlando, FL.

FDG-PET imaging predicts lung cancer patients' response to chemotherapy

An earlier indication of whether chemotherapy benefits non-small cell lung cancer patients, provided by positron emission tomography (PET) imaging, can guide doctors in offering them better care, according to researchers in the May Journal of Nuclear Medicine.

Attention training is worth examining for disorders with attentional components, like ADHD

Everyday experience and psychology research both indicate that paying close attention to one thing can keep you from noticing something else.

Fluorescent nanoparticles open up new possibilities for cellular imaging

Scientists from the University of Twente, the Netherlands, have successfully exploited the optical properties of fluorescent nanoparticles to broaden the scope of single-cell microscopy.

Ischemic-targeted approach to angioplasty among asymptomatic survivors of heart attack

When compared with intensive drug therapy, percutaneous coronary intervention (PCI, angioplasty) was more beneficial in reducing the long-term risk of major cardiac events among heart attack survivors with "silent ischemia", according to a study in the May 9 issue of Journal of the American Medical Association.

VCU to develop new form of radiation therapy

The National Cancer Institute has awarded a five-year, $10.7 million grant to Virginia Commonwealth University Massey Cancer Center researchers to develop a new form of radiation therapy that will enable the safe administration of more aggressive cancer treatments.

MRI and MRS can provide a 'road map' of the prostate

MRI and MRS can provide a roadmap of the prostate and assist in surgical planning of robotically assisted laparoscopic radical prostatectomy (RALRP), according to a recent study conducted by researchers at the University of California, Los Angeles.

Study provides clues about inability to imitate and empathize in autistic children

New imaging research at UCLA shows that impairments in autistic children's ability to imitate and empathize can be linked to dysfunction in the brain's mirror-neuron system.

Ultra-high-field MRI can detect multiple sclerosis lesions better than MRI

Ultra-high-field (7T) MRI can detect multiple sclerosis lesions better than MRI which can lead to possible earlier diagnosis and treatment, according to a new study by researchers from Ohio State University in Columbus, and Columbia University in New York.

Study provides new understanding of excessive gambling

People process information about financial loss through mechanisms in the brain similar to those used for processing physical pain, according to a new imaging study.

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.

Percutaneous radiofrequency ablation of liver tumors safe and effective

Percutaneous imaging guided radiofrequency ablation (RFA) of hepatocellular carcinoma is a safe and effective technique, with benefits such as reduced post-procedural pain and length of hospital stay, according to a study conducted by researchers from Changi General Hospital in Singapore.

New mapping technique will answer fundamental questions about chromosome structure

Researchers at the University of Illinois have developed a simple and economical technique for imaging and mapping fruit fly chromosomes.

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.
