Phase Mismapping - Video Lesson

Hey everybody, and welcome back to our course on MRI artifacts. In this lesson, we will discuss phase mismapping, including its appearance, the causes and potential impact on diagnosis, and how to troubleshoot to avoid it. Understanding phase mismapping and the strategies used to control it is essential for anyone working an MRI. Recognizing when an artifact is present and knowing how to respond helps prevent misinterpretation, improves diagnostic accuracy, and enhances patient care. Let's get started. First, let's discuss what phase mismapping is. MRI requires precise collection and organization of signal data to form accurate images. And as we've discussed in previous lessons, one of the challenges is patient movement. Phase mismapping is a phenomenon that occurs when motion from a patient interferes with the orderly collection of phase information. Understanding this phenomenon is essential because it can significantly impact image quality and could potentially lead to diagnostic errors.
