X-Ray Phase Tomography Enhanced with Synchrotron Radiation

2014 23 Oct

A recent study has confirmed the effectiveness of x-ray phase tomography with synchrotron radiation in detecting cancerous tissue in a mouse model. "Phase-contrast imaging" produced images with much enhanced contrast, making a clear differentiation between cancerous tissue and healthy tissue, according to researchers. The findings have been reported... Read more

Cardiac Imaging May Pose Radiation Risk

2014 04 Oct

According to a recent statement by the American Heart Association, doctors should ensure that patients understand the radiation-related risks of heart imaging tests before they undertake the procedures. These heart imaging tests may include nuclear stress tests, cardiac CT scans and fluoroscopy.  According to Dr. Rana Fazel, MD, MSc, chair of... Read more

2014 01 Oct

The American Heart Association (AHA) has issued a new scientific statement stressing the importance of clinicians to understand the risks of heart imaging involving radiation and to discuss these with patients before ordering such tests. The advisory came out amidst increasing reliance on the use of medical imaging to diagnose and treat patients with... Read more

Low-Dose CT Beats X-Ray in Lung Cancer Detection

2014 05 Sep

Ultra-low-dose computed tomography (CT) technology worked better than x-ray examination in detecting lung cancer, according to results of a pilot study conducted in Norway. Researchers tried to determine which imaging modality works best for the diagnosis of lung cancer by evaluating both x-ray images and ultra-low-dose CT scans of a small sample of... Read more

Children’s Heart Imaging-Associated Cancer Risk Initially Low

2014 10 Jun

The levels of low radiation, which children with heart disease are exposed to during X-rays, does not increase their lifetime cancer risk in a significant way, however as they undergo further complex imaging examinations involving higher radiation doses, the risk of cancer does increase slightly. These are the findings of a study conducted by... Read more

Radiation Risks in Paediatric CT: An Evaluation

2014 16 May

An online survey of members of a national Canadian PEM physician association was conducted to gauge possible malignancy risks from diagnostic tests that are conducted on children in the emergency department. The study was specifically related to head computed tomography (CT).     There is no doubt that CT is one of the most important diagnostic... Read more
