Multislice CT Scan

What are CT Scans?

CT (Computed Tomography) scans, also known as CAT (Computerized Axial Tomography) scans, are advanced medical imaging procedures that utilize X-rays and computer technology to create detailed cross-sectional images of the body. These images provide valuable diagnostic information for a wide range of medical conditions, allowing doctors to make accurate diagnoses and treatment plans.

How Do CT Scans Work?

During a CT scan, the patient lies on a table that moves through a doughnut-shaped machine called a CT scanner. The scanner emits X-rays from various angles around the body, which are detected by sensors on the opposite side. A computer then processes these signals to create detailed cross-sectional images, or "slices," of the body. These images can be viewed individually or reconstructed into 3D representations for further analysis by doctors.

Types of CT Scan

1. Routine CT Scan: Used for general imaging purposes, such as evaluating injuries, detecting tumors, or assessing the extent of internal injuries.
2. Contrast-Enhanced CT Scan: Involves the administration of a contrast dye, usually through injection or ingestion, to enhance the visibility of certain structures or abnormalities.
3. CT Angiography (CTA): Specifically focuses on imaging blood vessels to detect blockages, aneurysms, or other vascular conditions.
4. CT Bone Scan: Used to evaluate bone health and detect abnormalities, such as fractures, tumors, or infections, within the skeletal system.
5. Head CT: Produces detailed images of the head and brain, assisting in the diagnosis of conditions such as head trauma, strokes, tumors, or infections.
6. CT Chest Scan /Lungs: Examines the chest and lungs to detect conditions such as pneumonia, lung cancer, or pulmonary embolism.
7. CT Scan Neck: Provides detailed images of the neck area, including the thyroid gland, lymph nodes, and blood vessels, aiding in the diagnosis of conditions such as thyroid disorders or neck tumors.
8. Pelvic CT Scan: Offers detailed imaging of the pelvic area, assisting in the diagnosis of conditions affecting the reproductive organs, bladder, or gastrointestinal tract.
9. CT Scan Kidneys: Specifically focuses on imaging the kidneys and surrounding structures, aiding in the diagnosis of kidney stones, tumors, or other kidney-related conditions.
10. CT Scan of the Spine: Examines the spinal column and surrounding tissues to detect abnormalities such as fractures, herniated discs, or spinal tumors.
11. CT Guided Tissue Biopsy: Biopsy material is taken through deeper organs under CT scan guidance.
12. CT KUB Scan : Used to evaluate the kidneys, ureters, and bladder for conditions such as kidney stones, infections, or tumors. It provides clear cross-sectional images to assess urinary tract obstructions and abnormalities.
13. Sinus CT Scan : Provides detailed imaging of the nasal cavities, sinuses, and surrounding facial bones. It helps detect sinusitis, polyps, infections, or structural deformities affecting breathing and sinus drainage.
14. HRCT Scan (High-Resolution CT): Specialized CT scan of the lungs that produces high-definition images to detect interstitial lung disease, fibrosis, bronchiectasis, and other subtle lung abnormalities.
15. CECT Scan (Contrast-Enhanced CT): Involves the use of contrast dye to highlight blood vessels and soft tissues. It helps detect tumors, infections, vascular conditions, and internal organ pathologies with enhanced clarity.
16. Brain CT Scan : Generates detailed cross-sectional images of the brain and skull to diagnose stroke, hemorrhage, head injury, tumors, infections, and other neurological disorders.
17. CT PNS Scan (CT Paranasal Sinus): Focuses on the paranasal sinuses to identify inflammation, infections, cysts, or structural defects. Commonly advised for chronic sinusitis and pre-surgical evaluations.
18. Abdominal CT Scan : Provides detailed, cross-sectional 3D images of the abdomen, internal organs, blood vessels, and surrounding structures, helping diagnose conditions like liver disease, kidney stones, abdominal pain, or tumors.

Understanding CT Scan Results

After your CT scan test, the images will be interpreted by a radiologist, who will generate a report detailing their findings. Your CT scan centre doctor or healthcare provider will then discuss the results with you and explain their implications for your health.

• Identification of abnormalities, such as tumors, cysts, or fractures.
• Evaluation of the size, shape, and location of organs and tissues.
• Assessment of blood flow and vascular conditions.
• Detection of inflammation or infection.
• Confirmation or ruling out of suspected medical conditions.

FAQs on CT Scan

Is a CT scan painful?

No, undergoing a CT scan is generally painless. You may experience mild discomfort from lying still during the procedure or from the sensation of the contrast dye injection, if required. However, the scan itself is not painful.

How long does a CT scan take?

The duration of a CT scan varies depending on the area being scanned and the specific protocol. Most scans take only a few minutes to complete.

Do I need to prepare for a CT scan?

Preparation requirements may vary depending on the type of CT scan being performed. Your doctor or healthcare provider will provide specific instructions, which may include fasting or avoiding certain medications. For a contrast study normal renal function (s.creatinine) is required.

Are there any side effects of a CT scan?

While CT scans are generally safe, some people may experience allergic reactions to contrast dye or discomfort from lying still during the procedure. Rarely, there may be complications related to contrast dye administration.

Can I undergo a CT Scan Service if I'm pregnant?

Generally, CT scans are avoided during pregnancy unless essential for medical reasons. Inform your healthcare provider if you are pregnant or suspect you might be before scheduling a CT Scan Service.

What can a CT scan diagnose?

CT scans are used to diagnose a wide range of medical conditions, including but not limited to injuries, tumors, infections, bone disorders, and vascular diseases.
