Imaging Explained: What X-rays, CTs, MRIs and Ultrasounds Really Tell You

Many patients are told to "get imaging" without a clear explanation. In this episode Nurse Jessi explains what common diagnostic imaging tests actually show, why clinicians choose one over another, how to read basic findings, and what risks to know before you say yes. We'll walk through X-ray, CT, MRI, and ultrasound—how each works, typical uses, limitations, and when results are reassuring versus when they need follow-up. You’ll learn how contrast agents work, what radiation exposure means for your care, and simple questions and scripts to ask your clinician so you get the right test at the right time. This episode gives practical language to advocate for safer, smarter imaging decisions and three concrete takeaways you can use at your next appointment.
