What Happens During a CT Scan? Step-by-Step Process Explained

Published on September 29, 2025

A CT (Computed Tomography) scan is one of the most advanced imaging tests in modern healthcare. It creates detailed cross-sectional images of the body, helping doctors detect tumors, injuries, and infections with accuracy. For patients visiting Quadra Diagnostics, widely recognized as the Best Diagnostic Centre in Kolkata, understanding what happens during a CT scan can ease anxiety and ensure a smooth experience.

Step 1: Preparation Before the Scan

Before the test begins, patients may be asked to avoid food or drink for a few hours if contrast dye is required. Jewelry and other metallic items are removed to prevent interference. At Quadra Diagnostics, the most trusted diagnostics centre in Kolkata, trained staff guide you through every step, review your medical history, and make sure you are comfortable before starting the procedure.

Step 2: Getting into Position

You will be asked to lie on a padded table that slides into the CT scanner — a large, circular machine. To maintain accuracy, pillows or straps may be used to keep you steady. Technicians remain in touch throughout the scan. As a facility also known for Advanced MRI in Kolkata, Quadra ensures that patients feel safe and informed at every stage.

Step 3: The Scanning Process

During the scan, the table moves slowly while the scanner’s X-ray tube rotates around your body, capturing detailed images. The procedure is painless, though you may hear whirring sounds. If contrast dye is used, it is injected through an IV line to highlight blood vessels or specific organs. At Quadra Diagnostics, often considered the Best MRI facility in Kolkata, these steps are handled with precision, ensuring accurate results for every patient.

Step 4: After the Scan

Once the scan is complete, any IV line is removed, and most patients can return to daily activities immediately. Radiologists at Quadra Diagnostics analyze the results carefully and prepare a detailed report for your doctor. Being the Best Diagnostic Centre in Kolkata, Quadra ensures reports are delivered quickly, helping doctors make timely treatment decisions.
