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.

Use of combined PET/CT can confirm suspected colorectal cancer recurrence at early stage: Study

The use of combined positron emission tomography and computed tomography can confirm a suspected colorectal cancer recurrence at an early stage, helping significantly in treatment planning and improved targeted patient care, according to a study to be presented at the ARRS 2010 Annual Meeting in San Diego, CA.

Pay-for-performance may create unintended financial incentives for doctors to discriminate against obese patients

Pay-for-performance reimbursement models may create unintended financial incentives for doctors to discriminate against obese patients, measuring a patient's waist circumference may be more effective in predicting surgical outcomes than the more traditional body mass index measure, and childhood obesity doubles the risk of developing colon cancer, according to data being presented at Digestive Disease Week- 2010.

Colorectal pre-cancer can be detected through stool DNA testing: Mayo Clinic study

Research teams led by Mayo Clinic have demonstrated for the first time that two types of colorectal pre-cancers can be detected through noninvasive stool DNA testing. The two studies being presented demonstrate that stool DNA testing may be useful for detection of premalignant dysplasia in patients with inflammatory bowel disease and of an important type of colorectal pre-cancer called serrated polyps.

Data shows rates of colorectal cancer screening vary by race, ethnicity and method

Rates of colorectal cancer screening vary by race and ethnicity as well as method, according to data being presented at Digestive Disease Week- 2010. Scientists examine data on minority and older populations as well as utilization rates of virtual and optical colonoscopies to better understand adherence to recommended screening guidelines.

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.

Health outcomes explored at DDW 2010

Non-alcoholic fatty liver disease, which may soon be the leading indication for liver transplant, is found to be significantly associated with worse transplant outcomes. In addition, a new tool for diagnosing NAFLD represents an alternative to liver biopsy, which is more expensive and prone to complications, and ultrasound and alfafeprotein blood test screening are an effective alternative to CT scan and MRI for patients with cirrhosis at high risk for hepatocellular cancer.

CT Dose Summit to establish freely available guidelines for performing CT scans

A national "CT Dose Summit" in Atlanta, GA this week will bring together some of the world's leading experts on medical imaging to lay the foundation for assembling optimized guidelines for performing CT scans -- a common medical imaging procedure that uses X-rays to show cross-sectional images of the body.

Endovascular repair and surveillance appear to be safe alternatives for patients with small aneurysms

While repair of large abdominal aortic aneurysms (AAA's) is well accepted, randomized clinical trials have failed to demonstrate benefit for early surgical repair of small aneurysms over surveillance, according to researchers from New York-Presbyterian Hospital in New York.

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.
