CT Scan: Purpose, Procedure, Side Effects and CT Scan Cost.


Understanding the CT Scan: An Overview.

CT Scan – sometimes called a CAT Scan – is short-form (acronym) for a Computerized Axial Tomography Scan. A CT Scan typically combines multiple rotating X-Rays along with hi-end computerized processing to produce a more detailed ‘picture’ of the inner structures of a body – including bones, tissues and organs. A CT Scan offers significantly greater detail and clarity as compared to a regular X-Ray (it’s a bit like looking inside a slice of bread, instead of an outer view of the entire loaf). A CT Scan is typically done on our spine, heart, head, chest, abdomen, abdomen and knee. During a CT Scan, the body is made to pass through a tunnel-like machine which rotates through a 360 degree arc as it takes X-Ray images in rapid succession. These images are subsequently fed into a computer to produce an ‘all around’ 2D snapshot of any part of the body. A minimally invasive and painless procedure, a CT Scan can be done on any part of the body in little time. While essentially 2D in nature (ie, producing two dimensional image slices), a CT Scan can also be employed to create 3D images.

A CT Scan cost depends on the body parts which you want to scan. Below table showing a CT scan cost in Delhi NCR, India.

Why is a CT Scan Done?


A CT Scan can secure high quality images of blood vessels, soft tissues, lungs, brain, abdomen, bones, the pelvis and other parts of the body. It may be recommended by a doctor or medical professional for a variety of reasons. Some of the reasons a CT Scan is performed are:

  • To detect disorders in the bones, joints and muscles – such as a complex bone fracture or a tumor.

  • To help measure bone density and spine health.

  • To investigate or study internal structures and blood vessels.
  • To detect changes in conditions such as liver mass, heart ailments, emphysema and cancer.

  • To extract vital information regarding the brain – such as swelling in the arteries, bleeding, presence of tumor and others.

  • To evaluate the intensity or magnitude of internal damage or internal bleeding.
  • To detect an infection, a blood clot, excess fluid in the body, inflammation or a tumor.

  • To influence treatment decisions and roadmaps in cases of surgeries, radiation therapy and biopsies.

  • To aid a medical professional figure out the efficacy or progress of ongoing medication or treatment.


What is the Procedure For Doing a CT Scan?

A CT Scan is usually done in a hospital or radiology clinic, and is performed by a qualified radiology technologist. The patient may be advised by the guiding medical professional or doctor to abstain from eating or drinking for a few hours before the procedure begins. When it is time for the Test, the patient will be required to lie on a table – usually on the back, though sometimes it may be sideways or face-down as well. The table then starts to make its way slowly inside a large and circular (donut shaped) CT Machine that contains circling X-Ray beams within. As the body passes through the circle, the X-Ray beams capture a ring-like, cross-sectional image of the ‘slice’ of the body directly in its ‘gaze’ or range. After every ‘X-Ray shot’, the table (on which the patient is lying) will move a bit, enabling the machine to take the next ‘shot’. These shots are subsequently scanned and processed digitally to generate a series of 2D ‘slices’ of the body, each slice providing a detailed image of the bones, tissues, blood vessels and organs. The patient has to remain as still as possible during the scanning process to ensure ‘best results’. When the Scan is operation, nobody is allowed to be present in the room – with the exception of the patient, of course. During the process, the patient can communicate with the radiologist professional who is conducting the Scan via intercom – and vice versa. A CT Scan can take anywhere between a few minutes to a half-hour at the max, and one can usually return home almost immediately once the procedure has been completed.


What is a CT Scan With Contrast?

While a CT Scan will generate clear images of ‘dense organs and structures’ (ie, those with a high density), substances with a low density can turn out hazy and hard to detect. To make the latter more clearly visible, the patient may be administered a special ‘dye’ – technically referred to as a ‘Contrast Material’ – via injection (done to make the liver, gall bladder, urinary tract or blood vessels stand out sharper in the Scan results), orally (to enhance images of the digestive tract) or via Enema (this refers to instances when greater clarity is required for the intestines, and the Contrast Material is inserted through the rectum). To help the kidneys remove the Contrast Material after the procedure is over, one may be advised to drink a lot of fluid.


What Are the Risks Involved in a CT Scan?

A CT Scan essentially involves X-Rays, which in turn, are about ionized radiation. Technically, this does put one at the risk of DNA damage, thyroid complications and cancer. In reality, however, the probability of one contacting a fatal illness simply due to a CT Scan is considered by experts to be no more than 0.0005. Indeed, this quantum of radiation is understood to be the same as humans are ‘naturally’ (ie, via normal exposure to the environment) subjected to – in a time duration ranging between several months to several years. Pregnant women and children however may need to take suitable precautions – such as a Setting adjustments in the CT Scan machine – and a medical professional must be contacted in such cases.


What are the Side Effects of a CT Scan?

A CT Scan doesn’t come with too many side effects, except the bit we discuss under ‘Risks’. If someone is allergic to the Contrast Material (this is not uncommon), there may be a mild rash or slight itchiness, but nothing of a serious nature. Nonetheless, the medical professional in charge of the case may prescribe close monitoring of the health condition for a short period of time after the CT Scan is over. It is important, however, to disclose any medical condition or history (such as allergy to seafood, iodine or any ongoing medication), any kidney issue or whether one is taking Metformin (for diabetes) to one’s doctor or medical supervisor before the CT Scan.


What Does a Normal CT Scan Reading Mean?

A CT Scan that doesn’t show any visible indication(s) of tumor or blood clot, or any anomaly or disorder in the structure or conditions of bones, tissues or the organs of the body, is considered to be ‘normal’.
