Combined computed tomography (CT) and positron emission tomography (PET) - may detect the spread of head and neck cancer more accurately

"PET/CT is very helpful in determining where we should pinpoint our biopsies for recurrent disease," said Dr. Carol Shores, assistant professor of otolaryngology/head and neck surgery at UNC and the report's senior author. Shores is a member of the UNC Lineberger Comprehensive Cancer Center.

Virtual colonoscopy for colon cancer

Computed tomographic colonography (CTC) depicts cancers and other clinically important conditions that would be missed with standard colonoscopy and at very little additional cost, according to a study in the August issue of Radiology.

Innovative new brachytherapy planning tool

The Vitesse system is being used in more than 25 hospitals worldwide to speed up planning and enable treatments to take place within a day, avoiding the need for patients to stay in a hospital overnight.

White blood cell called a neutrophil appears to be crucial to abdominal aortic aneurysm formation

Each year, 200,000 Americans find out that the largest blood vessel in their body, the aorta, may burst open at any time. About 20,000 die suddenly from such a rupture. And another 36,000 have surgery to repair or replace the swelling section of aorta before time runs out.

Radiofrequency ablation (RFA) is an effective, longlasting treatment for small kidney tumors in selected patients

Massachusetts General Hospital (MGH) researchers have shown that radiofrequency ablation (RFA) - a minimally invasive way of destroying tissue - is an effective, longlasting treatment for small kidney tumors in selected patients.

Patients who need PET/CT scans should avoid drinking coffee

Patients who need a positron emission tomography (PET)/computed tomography (CT) procedure to evaluate known or suspected malignancies should lay off the java, according to research by Medhat M. Osman, M.D., Ph.D., assistant professor in the department of internal medicine's division of nuclear medicine and director of PET at Saint Louis University Hospital.

Experimental drug therapy could open new window for treatment of deadly stroke

A new type of drug therapy that is currently being tested in Canada could significantly reduce the death rate caused by the deadliest form of stroke. According to the Canadian Heart and Stroke Foundation, new developments in stroke research make it more important than ever that Canadians recognize and react to the warning signs of stroke.

CT screening lowers negative appendectomy rate from 20% to 3% at urban hospital

Five years ago, the negative appendectomy rate at Massachusetts General Hospital (MGH) in Boston was 20%, but since the advent of CT screening, it has dropped to 3%, say MGH researchers. The negative appendectomy rate measures how often patients with symptoms of appendicitis have their appendix removed and then are diagnosed as not having acute appendicitis.

High-tech imaging software locates more accurately the abnormal electrical impulses that produce heart arrhythmias

Loyola University Health System is one of the first hospitals in the United States to employ new high-tech imaging software - in conjunction with a three-dimensional cardiac mapping and navigation system - to locate more accurately the abnormal electrical impulses that produce heart rhythm disturbances (arrhythmias). This technology represents a major breakthrough in treating complex arrhythmias.

Tungsten-antimony breast shield reduces radiation dose to the female breast during chest CT by 43% to 73%

A new custom-designed tungsten-antimony breast shield reduces radiation dose to the female breast during chest CT by 43% to 73% without compromising diagnostic image quality, say researchers from the VCU Health System, Medical College of Virginia Hospitals and Physicians, in Richmond.

Soft tissue injuries can predict risk of facial fractures in trauma patients

Trauma patients with specific types of facial soft tissue injuries should have a CT (computed tomography) scan of the face as well as a standard head scan to determine the presence and severity of facial fractures, according to a study published in the May issue of the Journal of Oral and Maxillofacial Surgery.
