MRI Brain Common Pathologies II (Anatomy) - Video Lesson

Hey, everyone. Welcome to the second 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. Let's get started. First, let's address pituitary adenomas. These are benign tumors caused by abnormal cell growth. Triggers include genetic mutations or hormonal imbalances. Pituitary adenomas can disrupt hormone levels, causing symptoms like headaches or vision changes. These adenomas can be classified into two categories, macroadonomas and microadenomas. Macroadenomas measure greater than ten millimeters, while microadenomas are less than ten millimeters. Macroadenomas commonly cause vision issues as the size of the adenoma may put pressure
