An image-based skeletal dosimetry model for the International Commission on Radiological Protection reference newborn accounts for the unique 3D microstructure of newborn marrow cavities and bone trabeculae as seen under microCT imaging, suggesting that radiation doses to newborn bone marrow have been overestimated by existing clinical skeletal models, according to an article published in the March 5 issue of Physics in Medicine and Biology.
Humanetics obtained a global exclusive license from the Henry M. Jackson Foundation for the Advancement of Military Medicine for patents covering the use of BIO 300 as a medical radiation countermeasure.
According to a recent study published in the March 8 issue of Archives of Internal Medicine, prostate cancer patients who visit a urologist with or without a medical oncologist consultation are treated more frequently with hormone therapy, watchful waiting or a radical prostatectomy, while those who visit a radiation oncologist appear more likely to receive radiation therapy for the treatment of their disease.
In February, the Alliance for Radiation Safety in Pediatric Imaging expanded the Image Gently radiation dose initiative from CT and interventional radiology to computed radiography (CR) and digital radiography (DR) exams by hosting a Digital Radiography Summit at the Mallinckrodt Institute of Radiology at Washington University in St. Louis.
Project ProSPECTus is attempting to develop a new technology for next-generation SPECT imaging which will shorten imaging time, lower radiation doses, improve future diagnosis of cancer and the probability of successful cancer therapy while enabling a higher throughput of patients in hospitals.
Siemens Healthcare has introduced its Excel Edition 16- and 64-slice CT scanners, the Somatom Emotion and Somatom Definition AS CT, which are reportedly equipped with features to help reduce radiation dose.

CTC safe & effective for elderlyCT colonography (CTC), or virtual colonoscopy, is a safe and effective screening modality for the older patient population in the screening of colorectal cancer, according to a retrospective analysis published in the February issue of Radiology.
In a study evaluating the use of induction chemotherapy followed by radiation for larynx preservation in head and neck cancer patients, researchers of the Bretonneau Hospital in Tours, France found that half of patients reported no trouble eating or swallowing and most had a low-risk of voice disability after procedure, according to a presentation Feb. 25 at the Multidisciplinary Head and Neck Cancer (MHNC) Symposium.

ATLANTA--Currently, cardiovascular imaging accounts for 30 percent of all the medical radiation that people receive in the U.S., noted Andrew Einstein, MD, cardiologist and assistant professor of clinical medicine at Columbia University College of Physicians and Surgeons in New York City, during a symposium at the 59th annual American College of Cardiology (ACC) annual conference on Monday. Einstein also spoke to whether the current levels of radiation are appropriate, as well as strategies for reducing radiation exposure.
Royal Philips Electronics of the Netherlands launched the Gemini LXL, a new PET/CT scanner, and DoseAware, a new dose-reducing solution for interventional procedures at the European Congress of Radiology (ECR) 2010 this week in Vienna.
An Arkansas widower has filed a class action lawsuit against Lester E. Cox Medical Centers in the case involving the overradiation of 76 patients with brain cancer at CoxHealth of Springfield, Mo.
“Ultrasound is the established modality of choice to evaluate the female pelvis, so why do patients with pelvic masses or pain get a CT scan? In my opinion, doing a CT scan first for female patients with lower abdominal pain is dangerous and wasteful, a drain of much-needed healthcare dollars,” wrote Beryl Benacerraf, MD, in an editorial published in the March issue of the Journal of Ultrasound in Medicine.
Surgery with molecular fluorescence imaging using a dual fluorescent plus a magnetic marker decreases residual cancer, improves survival and MRI-guided clinical staging, according to two studies published in the March issue of Proceedings of the National Academy of Sciences.
Proton beam radiation therapy showed encouraging results for patients with locally advanced sinonasal malignancies, according to a study presented Feb.25 at the Multidisciplinary Head and Neck Cancer Symposium in Chandler, Ariz.

Concern for imaging-based patient radiation dose continues its surge. Recent patient radiation overexposure cases in the U.S., multiple studies relating CT scans to higher incidences of cancer and extensive media reporting on radiation exposure have given the issue of radiation exposure during imaging exams an increasingly high profile.

The use of health IT to reduce rehospitalizations will be welcome but also disruptive, said Stephen Jencks, an independent consultant in healthcare safety during a Feb. 24 webinar on the potential use of health IT to mitigate rehospitalizations, sponsored by the Agency for Healthcare Research and Quality (AHRQ).
During the Health IT Standards Committee meeting on Feb. 24 in Washington, D.C., the Clinical Operations Workgroup sought to gather comments on proposed recommendations on implementation specifications for content exchange, vocabulary and code set standards for the Interim Final Rule of meaningful use.
In 2006, the Center for Devices and Radiological Health (CDRH), a branch of the FDA, began examining the number of medical device reports they received. Over the past two years, the number of submitted reports has increased, sparking a demand for the CDRH to make a move to electronic reporting.
A new hospital breaking ground usually isn’t breaking news. But the vision of patient care at one new facility, tentatively named Palomar Medical Center West (PMC West), is currently illegal under California state law.
