CT radiation exposure is associated with increased risk of cancer development in patients, as ionising radiation is a known carcinogen agent. Radiologists know it is crucial to limit medical imaging exposure and are increasingly adamant on finding ways to avoid unnecessary testing and reduce CT doses. In a new study published in the BMJ , researchers...Read more

Computed tomography (CT) is commonly used to measure calcium, a component of plaque, in the coronary arteries. CT can also measure calcium in the abdominal aorta, the large vessel that carries oxygenated blood to the lower extremities. New research published in the journal Radiology finds that CT-based measures of calcification in the abdominal...Read more

Technological advancements and the ever-increasing use of computed tomography (CT) have greatly increased the detection of incidental findings, including tiny pulmonary nodules. The management of many "incidentalomas" is significantly influenced by a patient’s history of cancer. However, new research shows a significant number of CT requisitions do...Read more

A new study shows increased use of CTs in patients with non-serious injuries, such as fractures or neck strain, treated in emergency departments at California hospitals. The UCSF-led study, which tracked the use of the imaging from 2005 to 2013, found that CTs were more likely to be ordered in hospitals that were designated high-level trauma centres....Read more

Radiographic images, such as x-rays, mammograms and computed tomography (CT), help detect diseases like cancer in its early stages when treatment can be most effective. As these images are in black and white, detecting the difference between healthy tissue and abnormalities can be difficult. Now, a new technology called spectral (colour) computed tomography...Read more
