MRI Brain Common Pathologies I - Video Lesson

Hey, everyone. Welcome to today's lesson on common pathologies associated with MRI exams of a routine brain. In this lesson, we will discuss characteristics of routine pathologies seen in MRI and scanning techniques associated with those pathologies. It is important to remember there are many pathologies seen in MRI. These are just a few common ones a technologist should be familiar with. There are many different types of tumors that can be an indication for a brain scan. These fall into two specific categories, intraaxial and extraaxial. Intraaxial tumors originate within the brain tissue itself. These can include types of gliomas, like an astrocytoma or metastatic lesions. Extraaxial tumors originate outside the brain tissue, but in a contiguous area like the meninges. These can include types of meningiomas or schwannomas. It is important to use gadolinium contrast for tumors of any type. Gadolinium contrast can
