Computerized tomography scan, short form of CT scan, is a diagnostic imaging procedure done using a series of X-rays and computer technology to generate images of the internal organs of the body. A CT scan report shows detailed images of any part of the body, including the muscles, tissues, fat, organs, blood vessels, or bones.
CT scans are more detailed than standard X-rays. A standard X-ray captures images of a single organ, area of the body at a time and is used to detect only superfluous injuries or issues. It cannot provide in-depth information about the internal organs.
In a CT scan, the beam of light moves in 360 degrees, thereby capturing different views of the same organ or structure, providing greater detail. These images are further processed to create cross-sectional images of the bones, soft tissues and blood vessels inside the body, which are displayed in 2D or 3D forms on a monitor.
It is a non-invasive way of obtaining detailed internal images of the body. A CT scan is usually recommended to examine people who may have internal injuries from accidents, assaults or other types of trauma. These scans visualize in detail all the parts of the body and are used for diagnosing injury \or disease in the internal organs. Using these reports, doctors can plan surgical, medical or radiation treatments for the patients.
Freequently Asked Questions About CT-Scan
Q1. What can CT scans detect?
CT scans can diagnose bone and muscle disorders, such as fractures and bone tumors. They can exactly pinpoint the location of a tumor, blood clot or infection. Doctors use this precise information to guide procedures such as biopsy, surgery and radiation therapy. CT scans are used to detect and monitor diseases and conditions such as cancer, liver masses, lung nodules and heart disease.
CT scans can show bleeding and internal injuries, caused by accidents or trauma. They can help doctors compare scans taken over a period of time to find out if certain treatments are working or not. Scans of a tumor can over a period of time can show whether the patient is responding to radiation or other treatments given.
Doctors can study the shape and size of a tumor and suggest treatments or surgeries accordingly. CT scans can detect internal injuries or problems precisely, helping doctors suggest accurate treatments.Q2. Why would a Doctor Order a CT Scan?
Considering that a CT scan is costlier than an X-ray, you might be wondering why a doctor would suggest a CT scan. But sometimes, doctors need an accurate image of the internal issue to diagnose the right treatment. CT scans can detect joint and bone problems, like complex tumors and fractures.
For conditions like heart disease, cancer, emphysema, or liver masses, a precise image is required for doctors to understand the intensity of the injury or disease. An accurate image helps them suggest the right treatments such as surgeries, biopsies, or radiation. Mostly, doctors order a CT scan if they suspect a tumor or a blood clot in a particular area of the body.
CT scan reports can also help doctors see if the treatment is working or not. They can likewise change the treatment or stop it if they see any improvements in the disease.Q3. What is a CT scan vs MRI?
CT scans and MRIs are both used to capture internal images of the body. The biggest difference between the two is that MRIs (magnetic resonance imaging) use radio waves and CT (computerized tomography) scans use X-rays. They are both low risk scans, but each can prove to be a better option depending upon the circumstances.
MRIs use radio waves and magnets to view objects inside the body. They are used to diagnose problems with joints, wrists, ankles, heart, breasts, brain, and blood vessels. It is a loud machine and the patients are given earplugs to endure the scan.
A CT scan uses 3 dimensional X-raying to produce images of the internal organs. It is used typically to detect issues like tumors, bone fractures, cancer or internal bleeding.
CT scans are more widely used than MRIs as they are less expensive. But MRIs are considered to be superior in regards to getting a more detailed image. CT scans use X-ray, while MRIs use radio waves.Q4. Is CT scan painful?
CT scans are painless, easy and quick. As the machine uses a multidetector apparatus, the amount of time is drastically reduced. The only discomfort a patient may feel is to lie still for several minutes or from the placement of an IV.
A CT scan does not hurt generally. The patient may feel a quick pinch or sting when the IV is started. This IV is given to inject a dye to enable the processing. Some patients can feel warm or flushed or get a metallic taste in the mouth because of the dye. Some may feel nauseous or get a headache.Q5. How much does a CT scan cost?
There are different rates of CT scans depending upon the country, state and also on the area that needs to be scanned.
