2. Why MRI – Brain Angio & Neck Angio Is Important
Early diagnosis of vascular abnormalities in the brain and neck can prevent life-threatening conditions like strokes or brain hemorrhages. Many neurovascular problems do not show early symptoms but can progress silently. MRI – Brain Angio & Neck Angio helps in early detection and treatment planning.
Key reasons this scan is important:
-
Detects and maps blood flow obstructions
-
Identifies aneurysms before rupture
-
Evaluates vascular health post-surgery or stenting
-
Assesses brain perfusion after trauma or ischemic events
-
Supports neurosurgeons and cardiologists in comprehensive diagnosis
In patients with dizziness, vision problems, transient ischemic attacks (TIAs), or unexplained headaches, MRI angiography provides clear insights into the cause and severity of vascular changes.
3. Benefits of MRI – Brain Angio & Neck Angio
This diagnostic test offers multiple clinical and patient-friendly benefits:
-
Non-invasive test: No catheters or incisions are required.
-
No radiation exposure: MRI uses magnetic fields and radio waves instead of X-rays.
-
High-resolution images: Detailed visualization of veins, arteries, and blood flow patterns.
-
Early detection: Enables doctors to identify vascular issues before symptoms worsen.
-
Quick and accurate: Results are generated in a short time with high diagnostic precision.
Patients also benefit from enhanced comfort, since modern MRI systems are quieter and completed within 30–45 minutes.
4. How MRI – Brain Angio & Neck Angio Is Performed
The procedure is safe, quick, and painless. Patients are advised to remove all metallic objects before entering the MRI suite. The scan is performed with or without a contrast dye, depending on the indication.
Steps involved:
-
The patient lies on the MRI table, which slides into the scanner.
-
The technologist monitors the scan from an adjacent room.
-
If contrast is used, a small injection may be given through an IV line.
-
The scanner captures detailed 3D images of blood vessels in the brain and neck.
-
The data is processed and reviewed by a radiologist for abnormalities.
Typically, the scan takes about 30–60 minutes. Results are available within 24 hours for most diagnostic centers.
Parameters and Reporting
Common MRI angiography parameters include:
-
Imaging of Circle of Willis (Brain Angio)
-
Carotid and vertebral artery assessment (Neck Angio)
-
Contrast-enhanced Time-of-Flight (TOF) and Phase-Contrast sequences
-
Stenosis percentage and vessel lumen visualization
-
Flow velocity and perfusion mapping
The final report highlights vessel integrity, narrowing, flow direction, and possible vascular anomalies.
