What is a CT Scan?
Computed Tomography (CT scan) is an advanced non-invasive diagnostic imaging technique that uses X-rays combined with computer technology to produce detailed cross-sectional images of the body. Unlike standard X-rays, a CT scan provides layered (slice-by-slice) images, allowing doctors to examine bones, organs, blood vessels, and soft tissues with good clarity and precision — along with multiplanar and 3D processing techniques.
CT scans are widely used in emergency and routine diagnostics due to their speed, accuracy, and comprehensive imaging capability.
At Durga Diagnostics, all CT protocols follow AIIMS guidelines. Multiphase CT scans are properly timed to ensure the best imaging quality. AI-based reporting updated to current standards is available.
CT Scan with Contrast
A contrast-enhanced CT scan involves a special iodine-based contrast dye injected intravenously. Oral contrast or contrast enema may also be needed in some cases. This contrast agent helps in:
Enhanced visibility of blood vessels
Detecting tumors & infections
Differentiating normal vs abnormal tissues
Accurate diagnosis of complex conditions
Note: Side effects are rare but may include a warm sensation, metallic taste, or allergic reactions. Fasting for 4–6 hours and recent KFT is required before contrast injection.
Advantages of CT Scan

CT Scan Procedure & Preparation
CT scan preparation depends on whether contrast dye is being used. Follow these guidelines for a smooth experience:
For non-contrast CT (brain, chest HRCT, sinuses, renal stones) — no specific preparation needed. For contrast CT — fasting for 4–6 hours and recent kidney function tests (KFT) are mandatory.
Step-by-Step Procedure
1
You will be briefed about the procedure — including lying within the CT gantry and scan duration
2
Remove all metallic objects — jewelry, watches, hairpins, belts — which can cause image artefacts
3
You will lie on the scanning table which moves through the circular CT gantry
4
The scanner rotates around the body, capturing multiple X-ray images processed into detailed cross-sectional views
5
You may be asked to hold your breath briefly for clearer images in chest scans
6
For contrast scans, dye is administered intravenously before or during the scan
7
Not recommended for pregnant women due to radiation exposure — inform doctor if pregnant or planning pregnancy this month
Preparation Checklist
Fasting (Contrast CT)
4–6 hours fasting required. KFT report mandatory before contrast injection
Remove Metal Objects
Remove all jewelry, watches, hairpins and belts before scan
Inform Your Doctor
Tell doctor about contrast allergy, kidney problems, diabetes, thyroid conditions or pregnancy
Comfortable Clothing
Wear loose, comfortable clothes. You may be asked to change into a hospital gown
Appointment & Duration: Appointment recommended for faster service. Waiting time: 10–20 minutes. Non-contrast CT: 2–3 minutes | Contrast CT: 5–20 minutes. CT is significantly faster than MRI, making it ideal for urgent cases.
CT Scan — Frequently Asked Questions
Everything you need to know about CT scans at Durga Imaging Centre.
What is a CT scan and how is it different from an X-ray?
A CT scan uses X-rays combined with computer technology to produce detailed slice-by-slice cross-sectional images. Unlike a standard X-ray which gives a single flat image, CT provides layered images with multiplanar and 3D reconstruction — giving much more detail about bones, organs and blood vessels.
Is CT scan safe? Does it involve radiation?
CT scans involve low-dose radiation exposure and are generally safe when performed under medical supervision. They are not routinely recommended during pregnancy unless absolutely necessary. Modern CT machines have automatic exposure control to minimize radiation dose.
How long does a CT scan take?
Non-contrast CT takes just 2–3 minutes. Contrast CT takes 5–20 minutes. CT is significantly faster than MRI, making it ideal for emergency situations.
Do I need to fast before a CT scan?
For non-contrast CT (brain, HRCT chest, sinuses, kidney stones), no fasting is needed. For contrast CT, fasting for 4–6 hours is recommended and recent kidney function tests must be available before the injection.
What is contrast dye? Is it safe?
Iodine-based contrast dye is used to enhance visibility of blood vessels and organs. It is generally safe but may cause a warm sensation or metallic taste. Rare allergic reactions can occur. Inform your doctor about any allergies, kidney problems, diabetes, or thyroid conditions.
Can CT scan be done for children?
CT can be done for children but is used judiciously due to radiation. Low-dose protocols with automatic exposure control (AEC) are available to minimize radiation while maintaining image quality.
When will I get my CT scan report?
Standard reports are delivered within 24 hours. For emergency cases, reports are available within a few hours. Our radiologists are available 24x7 for telephonic discussion to avoid any delay in patient management.
