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.

Combining fMRI and PET scanning creates a way to compare different measurements of the brain's function concurrently

Clinical researchers from the University of Pennsylvania Health System (UPHS) are the first to combine fMRI and PET scanning in radiology, creating a way to compare different measurements of the brain's function concurrently. This analysis could lead to better diagnosis and treatment in patients suffering from brain disorders, like Alzheimer's disease.

Electron-beam computed tomography - a more accurate replacement for coronary catheterizations

Electron-beam computed tomography (EBCT) is more accurate than conventional catheter angiography for detecting a dangerous congenital heart abnormality that could cause sudden death, according to research by a Saint Louis University radiologist published last month in Catheterization and Cardiovascular Interventions: Journal of the Society for Cardiovascular Angiography and Interventions.

Patients in level I trauma centers were nearly 20 percent less likely to die than those in level II centers

Patients who are taken to a level 2 trauma center after suffering serious injury are significantly more likely to die than comparable patients treated at a major level 1 trauma center, according to researchers at the Keck School of Medicine of the University of Southern California.

Large tumors that block the sinuses can be removed endoscopically through the nose

The endoscopic approach worked well not only to remove large inverted papillomas in 18 patients ages 36 to 74 but also to watch for regrowth of the tumors that have a high recurrence rate and a small chance of becoming cancer. Patients were treated as outpatients and 56 percent remained disease-free at 29 months.

PET imaging with FDG represents one of the most promising tools for diagnosis of Alzheimer's

Positron emission tomography (PET) imaging--with the radiotracer fluorodeoxyglucose (FDG)--is a promising tool in detecting Alzheimer's disease in patients who have mild cognitive impairment (MCI), according to a study reported in the October issue of the Society of Nuclear Medicine's Journal of Nuclear Medicine.

Combining optical tomography with standard ultrasound imaging can help distinguish early-stage breast cancer

A new study shows that combining a technology called optical tomography with standard ultrasound imaging can help distinguish early-stage breast cancer from non-cancerous lesions--and potentially reduce the number of breast biopsies performed. The study appears in the October issue of the journal Radiology.

Still a long way to go in diagnostic evaluation of all patients who suffer ischemic strokes

Women who survive a stroke are less likely than men to get crucial tests of their heart and neck arteries that can help improve their treatment and reduce their risk of a second stroke, a new University of Michigan study finds.

Experimental radioactive compound can show images of heart damage up to 30 hours after a brief interruption of blood flow and oxygen

The discovery may help physicians in emergency rooms and in their offices determine whether a patient's chest pain, which may have subsided hours earlier, is related to heart disease or something else, such as indigestion.

PET brain scans of a brain chemical messenger system may prove sensitive enough to help plan brain surgery for epilepsy

When drugs fail to control epilepsy, brain surgery is often the only remaining therapeutic option. However, identifying the correct spot for surgery has traditionally required a separate preliminary -- and inherently risky -- surgical procedure.

First clinical guidelines to help improve the diagnosis and treatment of people with normal pressure hydrocephalus

An international team of medical experts led by a Virginia Commonwealth University researcher has established the first clinical guidelines to help improve the diagnosis and treatment of people with normal pressure hydrocephalus, a debilitating condition in the brain that often goes undiagnosed or is misdiagnosed as Alzheimer's or Parkinson's disease.

Key neural system at risk from prenatal exposure to alcohol

In a study of adult monkeys who were exposed to moderate amounts of alcohol in utero, scientists have found that prenatal exposure to alcohol - even in small doses - has pronounced effects on the development and function later in life of the brain's dopamine system, a critical component of the central nervous system that regulates many regions of the brain.

SARS can infiltrate brain tissue

Severe acute respiratory syndrome (SARS), by its very name, indicates a disease of the respiratory tract. But SARS can also infiltrate brain tissue, causing significant central nervous system problems, according to an article in the Oct. 15 issue of Clinical Infectious Diseases, now available online.

Enhanced imaging techniques could improve medical diagnosis

Chris Wyatt is a Virginia Tech electrical engineer who is attempting to provide the medical community with better, quicker, and more relevant images of the human body. The side effects are not bad either - lower medical costs, new treatments, and earlier disease detection.

Anorexia may be caused by change in brain chemical

A new study has found that women who have had a certain type of anorexia nervosa show a change in the activity of a chemical in their brain that is widely associated with anxiety and other affective disorders, for as long as one year after recovery.

Study indicates that patients with a cervical spinal injury may harbor additional spinal damage not visible on regular x-rays

In fact, more than a third of patients who were thought to have low-risk injuries actually have additional damage that may include significant fractures with the potential to produce serious spinal problems if not detected and treated properly.

Anorexia nervosa linked with alteration of the activity of serotonin in their brain

Women who have had a certain type of anorexia nervosa show an alteration of the activity of a chemical in their brain that is widely associated with anxiety and other affective disorders more than one year after recovery, according to a study in the September issue of Archives of General Psychiatry.
