Introduction to MRI of the brain

Imaging Planes
- Axial: Horizontal cut through the patient, offering a top-down view.
- Coronal: Vertical cut separating the front and the back.
- Sagittal: Vertical cut offering a profile view by separating the left and right sides.
- Image Presentation: Understanding the orientation of different planes and how the patient's right and left are presented in images.

Structural Overview
- Meninges and Layers: Understanding the layers between the skull and brain, including details about the subarachnoid space and the role of different layers.
- Brain Components: Detailed overview of cerebellum, brain stem, and cerebral hemispheres.
Cerebrospinal Fluid (CSF) Spaces
- Ventricles and Sulci: Learning about spaces filled with CSF and understanding their roles in the brain.
Brain Lobes and Matter
- Lobes: Identifying different lobes such as frontal, parietal, and temporal lobes, and understanding their functions.
- Gray and White Matter: Differentiating between these two and understanding their components and functions.
Blood Supply and Drainage
- Arterial Supply: Overview of the circle of Willis and its role in supplying blood to the brain.
- Venous Drainage: Learning about venous sinuses and their role in brain drainage.

T1 and T2 sequences: Understanding the differentiation and application of these main types of sequences.
Modifications: Utilizing intravenous contrast to highlight abnormalities and modifying sequences for optimal results.
MRA and MRV: Techniques to focus on the arterial (MRA) and venous (MRV) systems, highlighting blood vessels effectively.

Objective: Applying MRI techniques and brain anatomy knowledge to analyze various case studies.
Case Variety: Discussing a range of symptoms including confusion, drowsiness, and visual changes presented by different patients.
Diagnoses Derived from MRI
- Strokes: Identifying and understanding the MRI presentations of chronic infarcts.
- Tumors: Recognizing different brain tumors such as glioblastoma and primary CNS lymphoma through MRI imagery.
- Other Conditions: Learning to identify conditions like intracranial aneurysms and demyelination through MRI analysis.
- Comparative Analysis: Understanding the importance of comparing pre and post-contrast images for accurate diagnoses.

Recap: Brief review of the topics covered, including MRI techniques and brain anatomy.
Application: Emphasizing the importance of applying the acquired knowledge to recognize different pathologies through MRI imaging.
