CT angiography not necessary in patients suspected with pulmonary embolism

A new study suggests that computed tomography (CT) angiography might be unnecessary in many patients suspected of having pulmonary embolism (PE), based on the results of risk assessment analysis. PE risk assessment could help reduce radiation exposure and costs associated with CT angiography. The results of the study appear in the online edition and August print issue of the journal Radiology.

Noninvasive carotid artery ultrasound helps avoid coronary angiography

New research from NYU Langone Medical Center shows that a simple, inexpensive and noninvasive carotid artery ultrasound of the neck can be used as a preliminary diagnostic tool for coronary artery disease (CAD). This may be an alternative to the standard, expensive and more invasive coronary angiography.

22 Midwest facilities named Centers of Excellence in accelerated partial breast irradiation

Twenty-two facilities in the Midwest have been named Centers of Excellence in accelerated partial breast irradiation (APBI) for their use of the SAVI® applicator, an advanced therapy for breast cancer as part of breast conservation therapy. The SAVI applicator can provide important advantages for women with early-stage breast cancer.

New recommendations can lower radiation exposure for patients undergoing MPI procedures: ASNC

New recommendations published by the American Society of Nuclear Cardiology (www.asnc.org) could significantly lower radiation exposure for patients undergoing myocardial perfusion imaging (MPI) procedures. Focused on three areas — patient selection, test selection, and technology adoption — ASNC's information statement summarizes best practices for minimizing radiation exposure without sacrificing quality or clinical benefit to the patient.

No clear evidence of a mobile phone and brain cancer link

Use of mobile phones has been under scrutiny for a while now with many claiming a link between mobile phone use and brain cancer. The mild radioactive waves generated from mobile phones have so far been poorly understood. There are no known mechanisms by which mobile phone radiation could cause cancer. Unlike x-rays, mobile phone radiation is non-ionising, and is too weak to break apart DNA, which is necessary to induce other cancers. However scientists do agree that this radiation might speed up a growing brain tumor.

Carcinogenic potential of mobile phone use not clear cut

The most comprehensive international study to date on the association between mobile phone use and brain cancers has not shown a strong causal link between the two but research on their relationship needs to continue, Professor Bruce Armstrong from the School of Public Health says.

Challenges faced in cardiac imaging

When patients present with chest pain or other high-risk symptoms of heart problems, doctors increasingly rely on nuclear imaging and computed tomography (CT) tests to find out whether there is evidence of heart disease, blockages in the coronary arteries or reduced blood flow to the heart. Results of these procedures can help guide life-saving prevention and treatment options.

President's cancer panel focuses on environmental chemicals

An expert panel that advises the president on cancer said Thursday that Americans are facing 'grievous harm' from chemicals in the air, food and water that have largely gone unregulated and ignored. The President's Cancer Panel called for a new national strategy that focuses on such threats in the environment and workplaces.

CT technique is more specific than X-rays in detecting thoracic, lumbar spine fractures: Study

When trauma patients receive a computed tomography scan of the chest, abdomen, and pelvis, a technique called CT spine reformatting eliminates the need for X-rays of the thoracic and/or lumbar spine to detect spinal fractures. This technique can lower cost and overall patient radiation exposure, according to a study to be presented at the ARRS 2010 Annual Meeting in San Diego, CA.
