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

Point-of-care ultrasonography has distinct advantages over computed tomography (CT) in terms of portability, cost, lack of ionising radiation, and improved spatial resolution. Still, CT has superior diagnostic accuracy in many urgent and emergent conditions. Contrast-enhanced ultrasound (CEUS) using intravascular microbubbles holds promise to close...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
