A older patient is guided into a CT scanner — an essential diagnostic tool whose life-saving power is now being weighed against growing concerns about long-term radiation exposure. Computed tomography ...

A new study has set off alarm bells, attributing the overuse of computed tomography – or CT – scans to around 5% of new cancer diagnoses annually. Since 2007, this imaging technology has seen a 30% ...

Medical imaging scans that create detailed images of the body’s internal structures are widely used in medicine. Doctors need them to detect and manage certain types of cancer, assess the extent of ...

Recently, a patient came to the hospital where I work with a persistent cough. Their doctor had ordered a CT scan – a type of imaging that creates detailed cross-sectional pictures of the body’s ...

While these advanced imaging tools save lives by detecting injuries and illness, mounting evidence suggests they may come with long-term consequences that patients need to understand before agreeing ...

A new analysis estimates that more than 100,000 cancer cases per year could be caused by radiation from CT scans. In some cases, the information provided by a CT scan could also be obtained from other ...

Medical professionals use CT scans to help diagnose and stage bladder cancer. While CT scans can provide valuable information, they are not perfect and have certain limitations. However, CT scans may ...
