Patients with metabolic syndrome and moderate calcium levels in the coronary arteries have greater chance of blocked arteries

Conditions such as abdominal obesity, high blood pressure, abnormal cholesterol levels and high blood sugar are problematic enough for people all on their own.

Routinely reformatting computed tomography (CT) scans to view organs from several different directions may help radiologists improve diagnosis

"You can see things in one view that you might miss in another," said Craig Barnes, M.D., section head of pediatric radiology at Wake Forest Baptist's Brenner Children's Hospital. "It costs no more as relates to scan time or radiation exposure, and we believe it provides added value in diagnosis."

Women more vulnerable to chronic drinking than men are

A study in the May issue of Alcoholism: Clinical & Experimental Research addresses this gap in research, using computed tomography (CT) to examine brain atrophy in the brains of alcoholic men and women. The findings support and build upon a prior hypothesis that women develop alcohol-related brain damage more readily than men.

Breast CT may improve on mammography - more gentler, more accurate

A new breast screening technology that may be able to detect tumors earlier than mammography -- without the need for uncomfortable breast compression -- is being tested in patients at the University of California, Davis, Medical Center.

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

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.

Survey of ED doctors shows team-based stroke care, risk-reducing measures, needed to increase use of tPA

Forty percent of emergency physicians say they're unlikely to give stroke patients the only FDA-approved drug shown to improve their prognosis, even in an ideal setting, mostly because of the fear of causing brain bleeding.

Discrimination leads to coronary artery calcification in African-American women

The more discrimination African-American women report, the more likely they are to have coronary artery calcification, a buildup of calcium in the vessels that is associated with atherosclerosis, according to a study presented at the American Heart Association's 45th Annual Conference on Cardiovascular Disease Epidemiology and Prevention.

Smokers who receive abnormal results using computed tomography to screen for lung cancer are more likely to quit

According to a new study, smokers who receive multiple abnormal results using computed tomography (CT) to screen for lung cancer are more likely to quit, suggesting an opportunity for doctors to motivate smokers to quit smoking.

Movie techniques, MRI/CT data combine with computer modeling of knee/patella to aid surgery

Take the kinds of movie techniques that allow animation with true-life action, throw in an anatomically-based muscle, ligament, tendon, bone and soft-tissue geometries dataset, and add individual patient MRI or CT scan data.

Benefits of lung cancer screening with CT questioned

Annual screening with helical computed tomography (CT) can help radiologists detect lung cancers at their earliest, most curable stage, but has not been shown to reduce mortality from the disease, according to a study published in the April issue of the journal Radiology.

Combining PET and CT scans leads to more accurate radiation therapy for lung cancer patients

Using Positron Emission Tomography in addition to Computed Tomography can reduce the amount of radiation exposure to normal tissue in some lung cancer patients

PET and CT scans provides accurate detection and localization of foot infection in diabetic patients

Pioneering research with combined positron emission tomography (PET) and computed tomography (CT) scans provides accurate detection and localization of foot infection in diabetic patients, according to an article in the March issue of the Journal of Nuclear Medicine.

Whole-body computed tomography (CT) is not a cost-effective screening method

The use of whole-body CT as a screening tool for cancer and other diseases is the focus of an ongoing debate. Proponents of whole-body CT emphasize the potential benefit of early detection of disease, but others caution that the costs, false-positive findings and unnecessary radiation might render the procedure more harmful than beneficial.

Blood clots in the lungs could be prevented with computed tomography (CT) scans of the legs

Researchers found that indirect CT venography (CTV) could identify blood clots in the legs that have the potential to break free, travel to the lung and block an artery--a life-threatening condition known as pulmonary embolism.

25 Jan 2005

Researchers can now predict the likelihood of developing lung cancer

For the first time, researchers can predict the lung cancer risk for social smokers as well as habitual smokers.

Virtual colonoscopy raises issues for further study

The American Society for Gastrointestinal Endoscopy (ASGE) has reacted with caution to claims of the benefits of computed tomography (CT) colonography, also referred to as virtual colonoscopy, compared to standard colonoscopy.

Early results shed light on lung cancer screening advance

One in three smokers or former smokers screened for lung cancer at a baseline and one year follow-up visit using a recent advance in computed tomography tested positive according to a new study. Of those, 12 percent had lung biopsies, and 7 percent were diagnosed with lung cancer.
