Study reveals increased risk of leukemia among Chernobyl cleanup workers

A 20-year study following 110,645 workers who helped clean up after the 1986 Chernobyl nuclear power plant accident in the former Soviet territory of Ukraine shows that the workers share a significant increased risk of developing leukemia. The results may help scientists better define cancer risk associated with low doses of radiation from medical diagnostic radiation procedures such as computed tomography scans and other sources.

Anti-TNF-α therapy reduces CVD risk in patients with rheumatoid arthritis

Patients with rheumatoid arthritis exhibit a sub-clinical vasculitis that may underlie their increased risk for cardiovascular disease, shows research.

Combination of phase contrast tomography and EST can produce high-quality 3D breast images

Like cleaning the lenses of a foggy pair of glasses, scientists are now able to use a technique developed by UCLA researchers and their European colleagues to produce three-dimensional images of breast tissue that are two to three times sharper than those made using current CT scanners at hospitals. The technique also uses a lower dose of X-ray radiation than a mammogram.

Study shows few adolescent females undergo pregnancy testing in hospital emergency department

Few adolescent females undergo pregnancy testing in the hospital emergency department, even when they complain of lower abdominal pain, or before they are exposed to radiation for tests or examinations, according to an abstract presented Friday, Oct. 19, at the American Academy of Pediatrics National Conference and Exhibition in New Orleans.

Parametric response mapping could improve diagnosis and treatment of COPD

A new approach to lung scanning could improve the diagnosis and treatment of a lung disease that affects approximately 24 million Americans and is the country's third-highest cause of death.

NVIDIA video cards can help reduce radiation exposure from X-ray and CT scans

Video gamers are generally the biggest consumers of computer graphics cards, using the devices to boost the speed and resolution of their digital quests to fend off invading extraterrestrials or outwit hostile dragons. But researchers at Rensselaer Polytechnic Institute seek to harness the power of these computer graphics cards to solve one of the world's most pressing health care technology challenges: radiation exposure from X-ray and CT imaging scans.

Longer looks: The smells to treat PTSD; Nudging healthy choices; When a disabled daughter was shunned

On an Orlando college campus, veterans and active duty soldiers suffering from post-traumatic stress disorder inhale the unmistakable smell of burning tires, rotting garbage and Middle Eastern spices as part of a virtual reality treatment for the psychological wounds of war. Participants sit in a chair wearing a head-mounted display and video goggles connected to a computer system and a scent machine that puffs out the odors, recreating their memories of war.

CT shows promise in predicting COPD exacerbation risk

Measurement of the pulmonary artery-to-aorta ratio can predict the risk for exacerbations in patients with chronic obstructive pulmonary disease, particularly those that require hospitalization, say the authors of a US study.

Smoker's pack-years, age and area of emphysema are strong predictors of mortality in COPD

Identifying an individual's the smoking history could help doctors to predict survival time in people with COPD.

CT scan appears to predict risk of chronic obstructive pulmonary disease exacerbations

The respective size of two major arteries, visible on a simple computed tomography, or CT, scan, is a strong predictor of the risk of exacerbation of chronic obstructive pulmonary disease, according to new research from the University of Alabama at Birmingham published online Sept. 3, 2012, in the New England Journal of Medicine.

Fractional flow reserve CT shows potential to non-invasively identify coronary artery disease

A study published in the most recent issue of the Journal of the American Medical Association (JAMA) presented encouraging news regarding physicians' ability to determine blood flow and associated coronary artery disease (CAD) using noninvasive CT scanning technology.

FISH assay identifies only few lung cancer patients who could benefit from crizotinib

Break apart a couple worm-like chromosomes and they may reconnect with mismatched tips and tails - such is the case of the EML4-ALK fusion gene that creates 2-7 percent of lung cancers. Almost exactly a year ago, the FDA approved the drug crizotinib to treat these ALK+ lung cancer patients, who were likely never smokers. Informed doctors use the test called a FISH assay to check for the EML4-ALK fusion gene, and then if the test is positive, ALK+ patients benefit greatly from crizotinib.

Edge CT now available in NYU Langone's Department of Radiology clinical practice

NYU Langone Medical Center is the first in the country to offer patients access to the new Siemens Somatom Definition Edge single-source computed tomography system (Edge CT), one of the world's fastest CT scanners capable of generating high quality, 3-D diagnostic images using extremely low radiation.

Miniaturized wireless sensors can save lives of wounded soldiers

Early detection of blood loss to save the lives of soldiers wounded on the battlefield is the goal of a three-year research and development project to be launched this fall at Worcester Polytechnic Institute (WPI). Funded by a $1.9 million grant from the U.S. Army, the research will be conducted in collaboration with the University of Massachusetts Medical School (UMMS).

Coronary artery calcium tool proves effective in detecting risk of cardiovascular disease

Heart calcium scans are far superior to other assessment tools in predicting the development of cardiovascular disease in individuals currently classified at intermediate risk by their doctors, according to researchers at Wake Forest Baptist Medical Center.

NYU Langone offers chance to participate in lung cancer early detection study

NYU Langone Medical Center is a pioneer in lung cancer screening and offers comprehensive screening for individuals at risk for lung cancer. The NYU Langone Lung Cancer Screening Center is distinguished by its multidisciplinary approach and wealth of experience and is under the direction of the Divisions of Pulmonary Medicine, Thoracic Radiology and Thoracic Surgery.

Early CT ‘definitive’ for subarachnoid hemorrhage diagnosis

Cerebrospinal fluid analysis is only necessary for patients with thunderclap headache and a negative computed tomography scan if they undergo imaging more than 6 hours after headache onset, research suggests.

SPECT/CT with 99mTc-HMPAO-WBC can improve diagnosis of infectious endocarditis

When combined with standard diagnostic tests, functional imaging procedures have been shown to reduce the rate of misdiagnosed cases of infectious endocarditis. According to new research published in the August issue of The Journal of Nuclear Medicine, single photon emission computed tomography (SPECT)/computed tomography (CT) with 99mTc-hexamethylpropleneamine oxime-labeled white blood cells (99mTc-HMPAO-WBC) can improve the diagnosis of infectious endocarditis in hard-to-diagnose cases.
