Z-axis modulation reduces radiation dose associated with unenhanced CT head scans

Z-axis modulation can significantly reduce the radiation dose associated with unenhanced computed tomography (CT) scans of the head, according to a study to be presented at the ARRS 2010 Annual Meeting in San Diego, CA. Z-axis modulation is a simple technique that radiologists can use to adjust the radiation dose and obtain optimal image quality during CT scans.

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

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.

Whole body MRI helps physicians diagnose and treat breast cancer: Study

Whole body magnetic resonance imaging should be the imaging modality of choice for the detection of breast cancer metastases (when the cancer has spread beyond the breast) as it is highly accurate and can detect bone metastases while a patient is still asymptomatic (shows no symptoms), according to a study to be presented at the ARRS 2010 Annual Meeting in San Diego, CA.

AAA symposium features digital technologies in anatomical reconstruction

Techniques for using digital technology in separating conjoined twins, developing facial prostheses and acquiring data from anthropologic specimens will be among the topics presented at a symposium sponsored by the American Association of Anatomists (AAA; www.Anatomy.org) on April 28. The symposium is part of the Experimental Biology 2010 conference being held April 24-28, 2010 at the Anaheim Convention Center.

Computer-based system automatically tracks radiation dose exposure in patients receiving CT scan

Researchers have developed a computer-based system that can automatically track patient-specific radiation dose exposure (based on a patient's size and weight) on every patient that receives a computed tomography (CT) scan, providing patients with a way to start tracking their cumulative health care-related radiation exposure, according to a study to be presented at the ARRS 2010 Annual Meeting in San Diego, CA.

CACS used to improve classification of risk for prediction of coronary heart disease events

Use of a score based on the amount of calcium in coronary arteries in addition to traditional risk factors improved the classification of risk for prediction of coronary heart disease events, and placed more individuals in the most extreme risk categories, according to a study in the April 28 issue of JAMA.

New 4-D software program promises to improve treatment of lung cancer: Researchers

A new 4-dimensional software program promises to improve the treatment of lung cancer by allowing doctors to take the movement of breathing into account when administering radiotherapy, researchers announced today at the 2nd European Lung Cancer Conference in Geneva, Switzerland.

New method may aid in diagnosing lung cancer more effectively

Doctors may soon be able to diagnose lung cancer more effectively thanks to research performed at the National Institute of Standards and Technology (NIST), where scientists have found ways both to increase the accuracy of computed tomography (CT) scans and to lessen the amount of time necessary to perceive telltale changes in lung tissue.*

ECRI Institute's recommendations for controlling CT radiation dose

The benefits of computed tomography (CT) have increased greatly over the past decade. Now twice as powerful, it offers dynamic images of anatomy, including the beating heart. Future advancements promise to deliver even more clinical benefits. However, CT has always had a downside: it can deliver high radiation doses to patients, putting them at increased risk of developing cancer.

Cancer-related expenditures increase faster than any other area of health care: JAMA

From 1999 through 2006 the use of diagnostic imaging for Medicare patients with cancer increased, with use of positron emission tomography increasing the most significantly, according to a study in the April 28 issue of JAMA. Imaging costs for these patients also increased, outpacing the rate of increase in total costs among Medicare beneficiaries with cancer.

Coronary CTA can be alternative, non-invasive diagnostic imaging test to triage CAD patients: Study

Non-invasive coronary computed tomography angiography is a cost-effective alternative to invasive cardiac catheterization in the care of patients who have positive stress test results but a less than 50 percent chance of actually having significant coronary artery disease, according to a study in the May issue of the American Journal of Roentgenology.

Non-invasive coronary CTA cost-effective alternative to invasive cardiac catheterization for CAD evaluation

According to a study conducted at Thomas Jefferson University (TJU), non-invasive coronary computed tomography angiography (CTA) is a cost-effective alternative to invasive cardiac catheterization in the care of patients who have positive stress test results but a less than 50 percent chance of actually having significant coronary artery disease (CAD). The study will be published in the May issue of the American Journal of Roentgenology.

Protocol adjustments based upon weight can help lower radiation dose for pediatric chest CT scans

Adjusting the radiation dose based upon a child's weight can significantly lower the radiation dose associated with pediatric chest computed tomography (CT) scans, according to a study published in the May issue of the American Journal of Roentgenology (www.ajronline.org). CT scanning combines special X-ray equipment with sophisticated computers to produce multiple images or pictures of the inside of the body.
