Patients with chronic and recurrent conditions receive radiation exposures that may put them at increased risk for cancer via medical imaging, according to a study published in the May edition of the Journal of the American College of Radiology, which found that the proportion of these patients who received estimated total effective doses of greater than 50 mSv within three years was significantly higher for those diagnosed most recently.
To improve pediatric residents' ability to make decisions regarding imaging exams, radiologists must educate the residents with uniform case-based and didactic sessions, as each decision made by a resident reflects individual training, said an article published in the May edition of the Journal of the American College of Radiology.
Melanin-covered nanoparticles provide a novel approach to protection of bone marrow from ionizing radiation based on prevention of free radical formation by melanin, according to research published online April 24 in the International Journal of Radiation Oncology, Biology and Physics.
Researchers have determined the crystal structures of red fluorescent protein TagRFP and its derivative, the blue fluorescent protein mTagBFP and have also proposed a chemical mechanism by which the red color in fluorescent proteins is formed from blue, according to study results published April 23 in Chemistry & Biology.
Mario J. Garcia, MD, a cardiologist who helped develop and clinically implement cardiac CT angiography, has been recruited as co-director of the Montefiore-Einstein Heart Center and as chief of cardiology within the department of medicine at Montefiore Medical Center in New York City.
Chest ultrasound is a viable alternative to chest CT in evaluating pediatric patients with pneumonia and parapneumonic effusion, according to a study published in the December issue of the American Journal of Roentgenology.
Educating physicians about ventilation-perfusion (V/Q) scanning as an alternative to CT for the diagnosis of pulmonary embolisms led to a 23 percent decrease in patient exposure to radiation, according to a study presented today in Boston at the 2009 annual meeting of the American Roentgen Ray Society.
Scientists at Albert Einstein College of Medicine of Yeshiva University in New York City have piggybacked antibodies onto radioactive payloads to deliver radiation dosages that selectively target and destroy microbial and HIV-infected cells.

Medical imaging overutilization--a growing concern in the U.S.--exposes patients to unnecessary radiation, while also adding to rising healthcare costs, according to a study published online Aug. 24 in Radiology. In an interview, William R. Hendee, PhD, lead author, reviewed various methods by which medical imaging could be curtailed.
Dedicated contrast-enhanced (CE) breast CT delivered significantly improved conspicuity of malignant breast lesions, including ductal carcinoma in situ (DCIS), compared with unenhanced breast CT and mammography, according to a study published in the September issue of Radiology.
CT, ultrasound and MRI have helped shift biopsy techniques away from more invasive approaches toward image-guided percutaneous techniques, according to a study published in the September issue of Radiology. The trend toward less-invasive approaches translates into enhanced safety and efficiency and could lead to more interaction between patients and radiologists.
The Centers for Medicare & Medicaid Services’ (CMS) EHR incentive payments are not considered reimbursement for money expended on EHR technology, but are intended to offset the cost associated with adoption and ongoing meaningful use, according to CMS during an Aug. 12 webinar.
Funding incentives for EHR use is the main goal of the Centers for Medicare & Medicaid Services' (CMS) meaningful use initiative, and there are incentive programs for both hospitals and eligible professionals, according to Elizabeth Holland, health insurance specialist at the Department of Health and Human Services, who spoke during a CMS-sponsored webinar Aug. 8.
Stage 1 requirements for meaningful use incentives aim to strike a balance between the overall goal of EHR use and widespread adoption, while avoiding added work, said Jonathan Teich, MD, PhD, chief medical informatics officer at Elsevier Health Services, during a HIMSS webinar titled “Meaningful Use: Safety and Quality of Care.”
