Caution urged over overuse of CT scans in South Florida

The CT scan — a medical darling for its detailed images, diagnostic power and big profits — is being overused in South Florida and nationally so much that some experts worry the radiation may cause cases of cancer.

New reports this year assert that computed tomography scans expose patients to small but significant doses of radiation that can add up over time, findings that CT defenders dismiss as alarmist.

The reports warn doctors to limit CT radiation exposure to patients, especially children and small adults who are at elevated risk, and to use radiation-free ultrasound and magnetic resonance imaging (MRI) if possible.
