Medical Imaging, Decoded: What Your X‑ray, CT, MRI, and Ultrasound Are Actually For

Patients get scans all the time, but few people understand why a clinician orders an X‑ray instead of a CT, what MRI can (and cannot) reveal, or how radiation and contrast affect safety. In this 20‑minute monologue Nurse Jessi explains imaging from the bedside: clear comparisons of X‑ray, CT, MRI, ultrasound and PET; practical reasons clinicians choose one test over another; common findings and phrases in radiology reports; and simple, concrete questions you can ask so the result helps your care. You’ll learn how to weigh benefits, minimize risks (including pregnancy and contrast concerns), and prepare for the scan so it’s faster and more useful. The episode closes with at least three actionable takeaways you can use at your next visit, plus tips for advocating for better answers from your healthcare team.
