A CT scan, or computed tomography scan, is a medical imaging technique that uses specialized X-ray equipment to create detailed cross-sectional images of the body. These images provide valuable information about the internal structures, organs, and tissues, helping doctors diagnose and treat various medical conditions.

CT scans are performed for a variety of reasons, including:

1. Diagnosis: They are used to detect and diagnose a wide range of medical conditions, including injuries, infections, tumors, and abnormalities in organs or tissues.

2. Monitoring: CT scans can be used to monitor the progression of certain diseases or the effectiveness of treatment, such as chemotherapy or radiation therapy.

3. Guidance for Procedures: Ct Scan in Pitampura can provide precise guidance for medical procedures such as biopsies, surgeries, and needle aspirations, helping doctors target specific areas with accuracy.

The procedure for a CT scan typically involves the following steps:

1. Preparation: Depending on the area of the body being scanned, you may be asked to change into a hospital gown and remove any metal objects or jewelry that could interfere with the imaging process. In some cases, you may be instructed to avoid eating or drinking for a few hours before the scan.

2. Positioning: You will lie down on a narrow examination table that slides into the CT scanner, which resembles a large, doughnut-shaped machine.

3. Scanning: The CT scanner emits a series of X-ray beams as it rotates around your body. These X-rays are detected by sensors in the scanner, and the data is processed by a computer to create cross-sectional images of the area being examined.

4. Contrast Injection (if needed): In some cases, a contrast dye may be injected into a vein in your arm to enhance the visibility of certain structures or abnormalities on the CT images. This contrast dye may cause a temporary sensation of warmth or a metallic taste in the mouth.

5. Breath-holding: You may be asked to hold your breath for a few seconds during the scan to minimize motion artifacts and ensure clear images.

6. Image Review: The images obtained during the CT scan will be reviewed by a radiologist or healthcare provider, who will interpret the results and provide a diagnosis.

As with any medical procedure, there are potential risks associated with CT scans, including:

1. Exposure to Radiation: CT scans involve exposure to ionizing radiation, which can increase the risk of cancer, particularly with repeated scans. However, the benefits of CT scans often outweigh the risks, especially when they are necessary for accurate diagnosis and treatment.

2. Contrast Reaction: Some people may experience an allergic reaction to the contrast dye used in CT scans, which can range from mild itching or rash to more severe symptoms such as difficulty breathing or low blood pressure. However, serious reactions are rare.

It's essential to discuss any concerns or questions you have about ct scan in  rohini with your healthcare provider before undergoing the procedure. They can provide personalized guidance based on your medical history and specific circumstances.
