Must Know Facts Before Getting A CT in Kannur | Shaji's MRI

Doctors can examine inside your body with the help of computed tomography (CT ) scan. It produces images of your bones, organs, and other tissues using a combination of X-rays and a computer. It provides more information than just a standard X-ray.

A CT scan can be performed across any area of the body. It takes just a few minutes and is quick and painless. This read will help you to get more knowledge before getting a CT in Kannur.

How Do CT Scans Work?

A small X-ray beam circles around one region of your body.  This generates a set of photos from multiple perspectives. This data can be used for a computer to build a cross-sectional image. This two-dimensional (2D) scan reveals a "slice" of the inside of your body, similar to one piece of bread.

This procedure will be repeated in order to obtain a large number of slices. To build a detailed image of your organs, bones, or blood vessels, the computer layers these images one on top of the other. A surgeon, for example, would utilise this type of scan to examine all sides of a tumour in preparation for a surgery.

How Are CT Scans Done?

A scan would most likely be performed at a hospital or radiology facility. Before the procedure, your doctor may advise you not to eat or drink for a few hours. You may also need to put on a medical gown and take off any metal jewellery.

The CT scan will be performed by a radiology technologist. You'll lie on a table inside a giant, doughnut-shaped CT machine during the test. The X-rays swirl around your body as the table goes slowly through the scanner. Hearing a whirring or buzzing noise is common. Because movement can cause the image to blur, you'll be required to remain completely motionless. At times, you may need to hold your breath. The length of the scan will be determined by whatever portions of your body are being scanned. It can take anywhere from a few minutes to half an hour to complete. Most of the time, you'll be able to return home the same day.

What Is Its Purpose?

CT scans are recommended for a variety of reasons by doctors:

• CT scans can reveal abnormalities with the bones and joints, such as complex bone fractures and malignancies.

• CT scans can detect or aid in the detection of conditions such as cancer, heart disease, emphysema, and liver tumours.

• Internal bleeding and injuries caused by a road accident, are visible.

• They can aid in the detection of a tumour, clot, excess fluid, or infection.

• They're used by doctors to help them plan treatment and operations like biopsies, surgeries, and radiation therapy.

• CT scans can be compared by doctors to see if specific therapies are effective. Scans of a tumour over time, for example, can reveal if it is responding to chemotherapy or radiation.

What Is a CT Scan with Contrast?

Dense substances, such as bones, are easily seen on a CT scan. Soft tissues, on the other hand, do not show up as well. In the photograph, they may appear to be dim. A special dye known as a contrast substance may be required to help them appear more clearly. They look white on the scan and block X-rays, highlighting blood arteries, organs, and other structures.

Iodine or barium sulphate are the most common contrast materials. You could get these medications in one of three ways:

• Injection: The medications are injected into a vein directly. This is done to make your blood vessels, urinary tract, liver, and gallbladder more visible in the image.

• Orally: Drinking a drink containing the contrast material can help scans of your digestive tract, which is the conduit via which food passes through your body, go more smoothly.

• Enema: The contrast material can be injected into your rectum if your intestines are being scanned.

You'll need to drink plenty of fluids after the CT scan to help your kidneys flush out the contrast material.

Are There Any Potential Risks?

X-rays, which create ionising radiation, are used in CT scans. According to studies, this type of radiation can harm your DNA and cause cancer. However, the risk is extremely low: your chances of developing a fatal malignancy as a result of a CT scan are roughly 1 in 2,000.

However, the effects of radiation accumulate over time. As a result, each CT scan you get raises your risk. Ask your doctor about the risks and benefits of the treatment, as well as why the CT scan is required.

Children may be more vulnerable to ionizing radiation. This is due to the fact that they are still developing. They will also be exposed to radiation for a longer period of time. You should ask the doctor or technician if the CT machine's settings have been modified for a youngster before the operation.

If you're expecting a child, tell your doctor. If you need imaging of your stomach, your doctor may suggest an ultrasound or another non-radiation procedure.
