MRI Brain With Diffusion Studies
What is MRI Brain With Diffusion Studies?
Diffusion-weighted imaging (DWI) uses MR imaging to measure the water particles movement within a tissue. It uses radio waves and a magnetic field to produce brain images, tissues, and the skull. The swollen cells or tumors have lesser movement of water particles and appear in high signal density in DWI. The test detects stroke, cysts, Alzheimer’s disease, Dementia, tumors, and reduced blood flow to the brain. The symptoms of brain damage are dizziness, vertigo, double vision, difficulty in speaking, coordination loss, severe headaches, seizures, personality or memory changes, vomiting, fatigue, drowsiness, sleep, and memory problems.
The test takes 30-45 minutes to perform. The scan's sensitivity is about 88%–100% and is a safe, painless, and radiation-less test. Pregnant women should inform the doctor before the scan.
Why is MRI Brain With Diffusion Studies done?
- To distinguish between the brain tumors and intracranial infections
- To detect any infection in the brain and CSF (cerebro spinal fluid) region like meningitis, hydrocephalus, encephalitis
- To find out any congenital cranial nerve blockage or under developed brain structures from the childhood.
- To diagnose vascular brain strokes and edema due to accidental injury or trauma.
