Helium-based MRI scans may one day allow closer look at smoker lungs

Aided by a powerful imaging technique, scientists have discovered they can detect smoking-related lung damage in healthy smokers who otherwise display none of the telltale signs of tobacco use.

Researchers improve delivery of health care for pediatric patients

Having a young child scheduled for a magnetic resonance imaging (MRI) or computed tomography (CT) scan to diagnose a potentially serious condition can be worrying for parents.

Initial experience of FDG-PET/CT guided IMRT of head and neck carcinoma

Doctors have discovered that combining images derived from positron emission tomography and computed tomography in the planning and delivery of radiation treatment for patients with head and neck cancer leads to more accurate delivery of the radiation dose and an increased chance for survival.

Body weight alone is not a sufficient indicator of higher risk of mortality in men

A new study by Queen's University shows for the first time that visceral fat in the abdomen is directly associated with a higher risk of mortality in men.

Positron emission tomography identifies esophageal cancer patients who will respond well to treatment

New research at Wake Forest University Baptist Medical Center shows that Positron Emission Tomography (PET) is more accurate than conventional imaging in identifying patients who have good responses to chemotherapy and radiation treatment - a finding that could one day help some patients avoid surgery.

Better tests needed for fuller view of head injuries

Concussion patients with a normal head CT scan may believe they are free of brain injury, but CT scans often miss damage at the molecular level, warns a University of Rochester Medical Center study.

Magnetic resonance imaging can help rule out acute appendicitis in pregnancy

Magnetic resonance imaging (MRI) can help rule out acute appendicitis in pregnancy when ultrasound findings are inconclusive, according to a study in the March issue of Radiology.

Certain chemicals in the blood may indicate brain injury

Researchers at Children's Hospital of Pittsburgh have found that increased levels of certain proteins in the blood or spinal fluid may signal brain injury in infants with vomiting, fussiness and several other common symptoms.

UT Southwestern embraces robotic technology to advance future of surgery

Having a surgeon with four arms is one of the advantages of the latest robotic technology now being studied at UT Southwestern Medical Center.

Tumor size serves as a prognostic indicator for curability

Smaller tumors in the lungs appear to be less likely to have spread than larger tumors among patients with asymptomatic lung cancer, suggesting that early screening may be useful in detecting cancers that are still curable, according to a new article in the Archives of Internal Medicine.

Even asymptomatic former smokers should consider CT screening

Smokers and former smokers should be screened for lung cancer even if they don't have symptoms, according to a new study led by physician-scientists at NewYork-Presbyterian Hospital/Weill Cornell Medical Center.

Simple diagnostic imaging procedure changes treatment for lower back pain

A simple diagnostic imaging procedure can help identify patients with lower back pain who would benefit from spinal injections and spare those who would not, according to a study appearing in the February issue of Radiology.

First description of female-specific Ischemia Syndrome

Although ischemic heart disease - the reduction of blood flow that can lead to heart attacks - is often considered a "man's disease," it takes the lives of more women than men each year. In fact, in 2000, about 60,000 more women than men died from cardiovascular disease.

European markets for cardiac catheterisation imaging systems

With a sharp increase in the incidence of cardiovascular disorders and mortalities in Europe, the need for early detection as well as cardiac interventional procedures has created enhanced scope for the uptake of cardiac catheterisation imaging systems.

Smokers with a family history of lung cancer encouraged to undergo screening

To detect invasive lung cancer in its early stages, researchers urge current and former smokers who have a strong family history of the disease to take a lung function test and undergo screening with spiral computed tomography. The test is especially important should the previously diagnosed relative be young (around 50).

Buttock injections do not provide proper dose

Women may not be getting the most out of vaccines and other injections, according to a study presented at the annual meeting of the Radiological Society of North America (RSNA).

Breast CT may be better than mammography at detecting breast lesions

Breast CT, an investigational technology for early breast cancer detection, may be better than mammography at detecting breast lesions and is much more comfortable for women, researchers from the University of California, Davis reported at the annual meeting of the Radiological Society of North America in Chicago.

Stenting of the carotid artery significantly improves cognitive speed

Stenting of the carotid artery significantly improves cognitive speed and may improve memory function in some patients, according to research presented at the annual meeting of the Radiological Society of North America (RSNA).

Diabetic black men have lower amounts of atherosclerosis than diabetic white men

In a surprising outcome, investigators at Wake Forest University Baptist Medical Center found that diabetic black men have dramatically lower amounts of atherosclerosis, or hardening of the arteries, than diabetic white men.

Intensity modulated radiation therapy (IMRT) for head and neck cancer

Results from a University of Pittsburgh study evaluating intensity modulated radiation therapy (IMRT) for head and neck cancer determined the ideal doses for lessening treatment side effects. The findings were presented today at the 47th Annual Meeting of the American Society for Therapeutic Radiology and Oncology (ASTRO) in Denver.
