Study finds spinal bleeding in young children with abusive head trauma

A new study found that spinal bleeding is found often in young children who are victims of abusive trauma. The findings support performing complete spine imaging for children undergoing brain magnetic resonance imaging (MRI) for moderate or severe traumatic brain injury and suggest a pathway for distinguishing between abusive and accidental injury.

CT scans appear to help in diagnosis of gout

According to research presented at the Nov 2011, American College of Rheumatology Annual Scientific Meeting in Chicago, a type of computed tomography scanning (commonly called CT scans) appears to help in the diagnosis of gout by detecting the urate crystals that are often a symptom of the disease.

Annual chest radiographic screening does not reduce lung cancer mortality

In a trial that included more than 150,000 participants, those who underwent annual chest radiographic screening for up to 4 years did not have a significantly lower rate of death from lung cancer compared to participants who were not screened, according to a study in the November 2 issue of JAMA.

Chest X ray for lung cancer fails to improve survival compared to no screening: Study

This study followed 154,901 participants, about half of whom were women. About 10 percent were current smokers, and the rest were nearly evenly divided between former smokers and people who never smoked. Subjects were either offered a chest X-ray or no screening at all.

CT scans can help detect COPD among men smokers

Among men who were current or former heavy smokers, undergoing lung cancer screening with computed tomography (CT) scanning identified a substantial proportion who had chronic obstructive pulmonary disease (COPD), suggesting that this method may be helpful as an additional tool in detecting COPD, according to a study in the October 26 issue of JAMA.

CJC publishes paper on safety of cardiac imaging methods

Canadian Journal of Cardiology has published a paper on the safety of cardiac imaging methods. This study is important for patients worried about radiation exposure during X-ray based studies of the heart. X-ray based methods have greatly improved the diagnosis of heart disease, but they can produce significant levels of radiation exposure.

Virtual 18F-FDG PET/CT bronchoscopy may accurately detect NSCLC metastases

For patients with non-small cell lung cancer (NSCLC) the accurate determination of the lymph node status before therapy is critical to develop an individualized treatment plan. Research from the October issue of the Journal of Nuclear Medicine highlights a new way for this information to be collected -- a virtual fly-through three-dimensional 18F-FDG PET/computed tomography (FDG-PET/CT) bronchoscopy that has high diagnostic accuracy for the detection of regional lymph node metastases.
