What is a CT Scan?
Computed Tomography (CT) scan is a non-invasive imaging technique that uses X-rays to create detailed cross-sectional images of the brain and other body parts. In mental health, CT scans are valuable for identifying structural abnormalities and injuries that may affect mental functioning.
How it's Performed
Preparation
- Screening: Inform your doctor about any allergies, especially to contrast dye, and provide a full medical history.
- Clothing and Accessories: You’ll need to remove metal objects and wear a hospital gown.
During the Procedure
- Positioning: You will lie on a motorized table that slides into the CT scanner, a large doughnut-shaped machine.
- Imaging Process: The scanner rotates around you, taking X-ray images from different angles. You might be asked to hold your breath briefly to avoid blurring the images.
- Contrast Dye: In some cases, a contrast dye is injected to enhance image clarity. It may cause a warm sensation or metallic taste.
- Duration: The scan typically takes 10 to 30 minutes.
Post Procedure
- After the CT scan, the images are reviewed and analysed by a radiologist. The radiologist interprets the detailed cross-sectional images of your brain or other examined areas, looking for abnormalities or conditions that may affect your mental health. This analysis is compiled into a comprehensive report and shared with your doctor.
