CT Cerebral Angiography (CT Cerebral Angio) – Advanced Brain Vessel Imaging
CT Cerebral Angiography (CTA) is a specialized non-invasive imaging procedure that provides detailed visualization of the blood vessels in the brain. Using advanced computed tomography (CT) scanning and a contrast dye, this technique helps detect vascular abnormalities, blockages, aneurysms, and strokes with high precision.
Key Features:
✅ High-Resolution 3D Imaging – Captures detailed cross-sectional and 3D images of cerebral blood vessels.
✅ Non-Invasive & Fast – Quick scan time (typically 5–15 minutes), minimizing patient discomfort.
✅ Contrast-Enhanced Visualization – Uses iodine-based contrast dye to highlight arteries and veins.
✅ Comprehensive Brain Vessel Mapping – Ideal for evaluating blood flow and detecting abnormalities.
✅ Seamless Digital Integration – Compatible with PACS and DICOM for efficient storage and sharing.
Applications:
🔹 Stroke Detection: Identifies blockages, stenosis, and ischemic changes.
🔹 Aneurysm & Vascular Malformations: Detects aneurysms, AVMs, and other abnormalities.
🔹 Pre-Surgical Planning: Helps neurosurgeons prepare for vascular interventions.
🔹 Brain Tumor Evaluation: Assesses vascular supply and tumor-related angiogenesis.
🔹 Traumatic Brain Injury (TBI): Examines blood vessel damage after head trauma.
Benefits:
✔ Accurate & Fast Diagnosis – Essential for time-sensitive conditions like strokes.
✔ Minimally Invasive – Requires only IV contrast injection, avoiding catheter-based procedures.
✔ Low Radiation Exposure – Optimized imaging protocols ensure patient safety.
✔ Enhanced Treatment Planning – Provides neurosurgeons and neurologists with crucial insights.
✔ Advanced 3D Reconstruction – Helps visualize complex vascular structures with precision.
Technical Specifications:
- Procedure Time: 5-15 minutes
- Slice Thickness: 0.5–1.0 mm for high-definition imaging
- Contrast Agent: Iodinated contrast (typically 50–100 mL)
- Imaging Modes: Axial, coronal, sagittal, 3D reconstruction, and maximum intensity projection (MIP)
