Radiologists urge judicious use of radiation-based imaging in children

A CT scan can mean the difference between an accurate and a wrong diagnosis, timely and delayed treatment and, in some cases, life and death. But because CT scans and other tests that use X-ray technology expose the body to often large doses of radiation, their unnecessary, repeated and excessive use may increase cancer risk, especially in children.

Study analyses CT for screening of coronary artery calcification in radiation-induced cancer cases

A study based on computer modeling of radiation risk suggests that widespread screening for the buildup of calcium in the arteries using computed tomography scans would lead to an estimated 42 additional radiation-induced cancer cases per 100,000 men and 62 cases per 100,000 women, according to a report in the July 13 issue of Archives of Internal Medicine, one of the JAMA/Archives journals.

Study finds certain MRI sequences as accurate methods of assessing stent stenosis

Researchers have found that magnetic resonance imaging (MRI) may be sufficient for the routine surveillance of some great vessel (primary blood vessels [e.g., aorta and vena cavae]) stents that are commonly used to treat congenital heart defects (a defect in the structure of the heart and great vessels that is present at birth) in children and young adults, according to a study in the October issue of the American Journal of Roentgenology (www.ajronline.org). MRI is a noninvasive medical test that helps physicians diagnose and treat medical conditions.

New computerized catheter makes surgical treatment of atrial fibrillation faster, cheaper and more effective

Atrial fibrillation is a heart disorder that affects more than two million Americans, and is considered a key contributor to blood clots and stroke. Now researchers from North Carolina State University are developing a new computerized catheter that could make the surgical treatment of atrial fibrillation faster, cheaper and more effective - while significantly decreasing radiation exposure related to the treatment.

Study to assess impact of radiation exposure on multiple cancer risk

It is well known that exposure to radiation has multiple harmful effects - including causing cancer - but until now, it has been unclear to what extent such exposure increases a person's risk of developing more than one cancer. The first large-scale study of the relationship between radiation dose and risk of multiple cancers among atomic bomb survivors in Hiroshima and Nagasaki, Japan reveals a similar risk in the development of first and second subsequent cancers.

Emergency physicians to present research studies at Research Forum 2010

The risks associated with boarding admitted patients in the emergency department – including patient mortality – as well as proposed solutions will be key themes of Scientific Assembly, the annual meeting of the American College of Emergency Physicians. In addition, emergency physicians will present more than 450 research studies during 2010 Research Forum, the premier, annual scientific research event focused on the latest advances in the practice of emergency medicine.

BARDA awards contract to develop treatment for ionizing radiation exposure

The U.S. Department of Health and Human Services' Biomedical Advanced Research and Development Authority (BARDA) today awarded a $153 million contract to Cellerant Therapeutics, Inc. of San Carlos, Calif., to continue developing a new way to treat an illness caused by exposure to high levels of ionizing radiation which can damage the body's cells - the type of radiation that would come from a nuclear blast.

Study shows molecular imaging benefits treatment planning for wide spectrum of cancers

A series of studies published in the September Journal of Nuclear Medicine (JNM) show that molecular imaging plays a critical role in the evaluation and treatment planning for a broad spectrum of cancers, including thyroid cancer and lymphoma.

MRI recordings at one fiftieth of a second

"Please hold absolutely still": This instruction is crucial for patients being examined by magnetic resonance imaging (MRI). It is the only way to obtain clear images for diagnosis. Up to now, it was therefore almost impossible to image moving organs using MRI. Max Planck researchers from G-ttingen have now succeeded in significantly reducing the time required for recording images - to just one fiftieth of a second.

Nanotherapeutics files NanoDTPA IND for treatment of radiation exposure

Nanotherapeutics, Inc., announced that it has filed an Investigational New Drug (IND) Application with the Food and Drug Administration (FDA) for NanoDTPA™ an orally administered capsule that is a less invasive treatment alternative to the FDA approved injectable Zn-DTPA (diethylenetriamine pentacetic acid). DTPA is used to remove radioactive compounds from the body to help eliminate the contamination. The NanoDTPA™ capsule is a unique orally-bioavailable fine particle formulation that allows DTPA to be absorbed into the body from the gastrointestinal tract.
