What's inside (67 total slides)
| Section | Slides |
|---|---|
| Cover | 1 branded title slide |
| 6 Category Dividers | Congenital / Vascular / Neoplastic / Infective / Demyelinating / Metabolic-Traumatic |

| Agenesis of Corpus Callosum | Sagittal T1/T2 + axial FLAIR — colpocephaly, parallel ventricles |
| Chiari I | Sagittal T1 — peg tonsils below foramen magnum |
| Dandy-Walker | Sagittal T2 — enlarged posterior fossa cyst |
| Holoprosencephaly | Axial T2 — monoventricle, fused thalami |
| Lissencephaly | Axial T2 — smooth brain, thick cortex |
| Tuberous Sclerosis | Axial T2 + GRE — subependymal nodules + cortical tubers |
| Glioblastoma | Axial Gd-T1 — butterfly pattern crossing corpus callosum |
| Ischemic Stroke | DWI + ADC — posterior circulation restriction |
| Multiple Sclerosis | Sagittal FLAIR — Dawson fingers perpendicular to ventricles |
| Medulloblastoma | Sagittal T1 Gd + axial T2 — midline posterior fossa mass |
