Minimal dose computed tomography better at detecting new or recurrent lung cancer

Lung cancer is associated with very high mortality, in part because it is hard to detect at early stages, but also because it can recur frequently after surgical removal.

New protocol for reducing the use of SPECT SPI is found to be diagnostically safe

A new stress test protocol that investigates reducing the use of perfusion imaging in low risk patients undergoing SPECT myocardial perfusion imaging for possible angina symptoms was found to be diagnostically safe, revealed a US retrospective analysis.

SAGE announces launch of new international open access journal of sports medicine

SAGE today announces the launch of a new international open access journal, the Orthopaedic Journal of Sports Medicine. This journal was developed by the American Orthopaedic Society for Sports Medicine in collaboration with professional sports medicine organizations from around the world as a global, peer-reviewed open access journal that will publish content for both researchers and practitioners studying orthopeadic sports medicine, arthroscopy, and knee arthroplasty.

Increased accumulation of coronary artery calcium leads to heart attack risk

Patients with increasing accumulations of coronary artery calcium were more than six times more likely to suffer from a heart attack or die from heart disease than patients who didn't have increasing accumulations, according to a recent study published in the Journal of the American College of Cardiology.

PET/CT may enhance detection of inflammatory bowel diseases in the future

Inflammatory bowel diseases, such as Crohn's disease and ulcerative colitis, may be detected and monitored more effectively in the future with positron emission tomography/computed tomography, according to research published in the May issue of The Journal of Nuclear Medicine.

Ocular tuberculosis presents a diagnostic challenge

Mycobacterial ocular inflammation typically arises without concomitant systemic or pulmonary disease and should be suspected in patients who do not respond to anti-inflammatory therapy.

Directed training facilitates out-of-hours emergency brain scans

An intensive teaching session helps emergency department physicians to reliably interpret head computed tomography scans when a radiologist is not on duty, a study shows.

Researchers use contrast-computed tomography for anatomical reconstruction of human heart

On April 18th JoVE (Journal of Visualized Experiments) will publish a new video article by Dr. Paul A Iaizzo demonstrating the anatomical reconstruction of an active human heart. The research uses contrast-computed tomography (CT) to allow in-depth 3-D computer modeling of hearts that can be used for prolonged archiving.

Study shows long-term exposure to fine particle matter air pollution is associated with atherosclerosis

The association between road traffic and heart disease has been suggested in several studies. In 2012 a large prospective cohort study from Denmark showed that traffic noise was significantly associated with risk of heart attack - for every 10 decibel increase in noise exposure (either at the time of the attack or over the five years preceding it) there was a 12% increased risk.

Preclinical study of cabozantinib in prostate cancer bone metastasis model presented at AACR meeting

Exelixis, Inc. announced the presentation of preclinical data that provide insight into the mechanism of action of its lead compound, cabozantinib, with respect to its activity against prostate cancer tumors that have metastasized to the bone.

Researchers develop new imaging system for mouse brain studies

Setting a mouse free to roam might alarm most people, but not so for nuclear imaging researchers from the U.S. Department of Energy's Thomas Jefferson National Accelerator Facility, Oak Ridge National Laboratory, Johns Hopkins Medical School and the University of Maryland who have developed a new imaging system for mouse brain studies.

Researchers develop software tool to noninvasively characterize pulmonary adenocarcinoma

A multidisciplinary team of researchers at Mayo Clinic has developed a new software tool to noninvasively characterize pulmonary adenocarcinoma, a common type of cancerous nodule in the lungs.

Male smokers with low levels of serum bilirubin are at higher risk for lung cancer

Elevated levels of bilirubin in the blood get attention in the clinic because they often indicate that something has gone wrong with the liver. Now researchers have found that male smokers with low levels of the yellow-tinged chemical are at higher risk for lung cancer and dying from the disease.

Penn Medicine study finds lower utilization of CTC for cancer screening

In 2009, the Centers for Medicare and Medicaid Services halted reimbursement for so-called "virtual colonoscopy" for routine colon-cancer screening in asymptomatic patients, in part due to concerns over how this procedure, computed tomography colonography, was being used in the elderly population.

V/Q imaging can detect early stages of COPD

In vivo ventilation/perfusion (V/Q) imaging can detect early changes to the lung caused by cigarette smoke exposure and provides a noninvasive method for studying lung dysfunction in preclinical models, according to research published in the April issue of The Journal of Nuclear Medicine.

Luminex collaborates with Merck to design companion diagnostic device for Alzheimer’s disease

WHITEHOUSE STATION known as MSD outside the United States and Canada, and Luminex Corporation have signed a collaboration and license agreement to develop a companion diagnostic device that will be evaluated to help screen patients for recruitment into Merck's clinical development program for MK-8931, a novel oral beta amyloid precursor protein site cleaving enzyme (BACE) inhibitor and Merck's lead investigational candidate for Alzheimer's disease (AD).

Marsupials shed new light on functional morphology

When, how and why modern humans first stood up and walked on two legs is considered to be one of the greatest missing links in our evolutionary history. Scientists have gone to the far ends of the earth - and the wonderful creatures in it - to look for answers to why we walk the way we walk.

Maxillary sinuses allow nose to change shape, say researchers

Pity the poor maxillary sinuses. Those bulbous pouches on either side of the human nose are known more for trapping mucus and causing sinus infections than anything else. They were thought to be an evolutionary relic of our distant past, with little known present value.
