Revascularization and blood-brain barrier breakdown may cause parenchymal enhancement with contrast agents. MRI Equipment • The traditional MRI unit is a large cylinder-shaped tube surrounded by a circular magnet. Old (several weeks to years): Low signal on T1, high signal on T2. Interact with scrollable cases, watch microlearning videos, and earn CME. Brain images are mostly noisy and inhomogeneous; therefore, it is quite challenging to make accurate segmentation on these images. In addition, familiarity with MR pulse sequences and signal intensity Different sequences like T1 and T2 provide different tissue contrasts. Use the mouse scroll wheel to move the images up and down, or alternatively, use the tiny arrows (→) on both sides .
