DWI & ADC in Stroke — Bright vs Dark Made Simple 🔍 Understanding the difference between DWI and ADC is key in identifying acute stroke. ✅ DWI: Bright in acute stroke (restricted diffusion) ✅ ADC: Dark in acute stroke (low diffusion values) Always compare both maps to confirm true diffusion restriction and avoid T2 shine-through errors. radiologysimplifide — one concept at a time 💡 #RadiologySimplified #RadiologyEducation #StrokeImaging #MRI #DWIMRI | Radiology Simplified

Stroke occurs when blood supply is reduced or stopped (seen here by the lack of perfusion in the ASL) to the brain, depriving brain tissue from getting oxygen and nutrients. MRI has a high degree of sensitivity and specificity for the diagnosis of stroke in the early progression of the disease. Diffusion weighted imaging (DWI) is especially helpful as it can detect areas of the brain with restricted diffusion caused by the stroke. In the acute phase, there will be high signal on the DWI and corr
