ABOUT Computed Tomography Scan - CT-Scan
A CT scan, also known as a computed tomography scan or CT scan, is a non-invasive medical imaging technique used in radiology to provide comprehensive pictures of the body for diagnostic reasons. Radiographers or radiology technologists are the people who do CT scans.
CT scanners analyze X-ray attenuation by various tissues inside the body using a revolving x-ray tube and a row of detectors in the gantry. CT scans provide more information than traditional X-rays.
A beam of energy is focused towards the bodily portion being analyzed in traditional X-rays. The fluctuations of the energy beam as it passes through skin, bone, muscle, and other tissue are captured by a plate behind the body part.
While a conventional X-ray can provide a lot of information, it lacks a lot of detail about interior organs and other structures.
The X-ray beam of a CT scan moves in a circle around the body. This enables a variety of perspectives of the same organ or structure, as well as a greater level of detail.
The X-ray data are transferred to a computer, which analyses it and presents it on a monitor in two-dimensional form.
What should I do to prepare for a CT scan?
When you book an appointment for a computed tomography angiography (CTA) or a virtual colonoscopy, you will be given precise instructions.
PRECAUTIONS: Please consult your doctor before booking the exam if you are pregnant or suspect you may be pregnant.
YOU MIGHT BE REQUIRED TO CHANGE INTO A PATIENT GOWN.
If this is the case, you will be given a robe. Any piercings should be removed, and all jewelry and valuables should be left at home.
MEDIA WITH CONTRAST: Contrast may be recommended for your exam.
The contrast medium aids the radiologist's ability to detect aberrant structures and better comprehend normal anatomy. Iodine-based contrast media should not be used in some patients. If you have any concerns about your renal function, please let your radiologist know ahead of time. They might be able to do the scan without the contrast medium or locate another imaging exam.
The double-contrast study is the most frequent form of CT scan with contrast, and it requires you to consume a contrast media before your test begins in addition to the IV contrast. The more contrast you can drink, the easier it is for the radiologist to see your digestive tract on the photographs.
What are the dangers of having a CT scan?
⦁ If you are pregnant or suspect you are pregnant, you should tell your doctor right away.
⦁ A CT scan exposes you to a little quantity of radiation. You might want to inquire with your doctor about the quantity of radiation utilized during the CT treatment, as well as the hazards associated with your specific scenario.
⦁ Tell your doctor ahead of time if you feel claustrophobic or quickly feel worried. To make you more comfortable, you may be given a light sedative to consume before the treatment.
What Is Its Purpose?
CT scans are ordered for a variety of reasons by doctors:
⦁ CT scans can reveal abnormalities with the bones and joints, such as complicated bone fractures and malignancies.
⦁ CT scans can detect or aid in the detection of conditions such as cancer, heart disease, emphysema, and liver tumors.
⦁ Internal bleeding and injuries, such as those caused by a vehicle collision, are visible.
⦁ They can aid in the detection of a tumor, clot, excess fluid, or infection.
⦁ They're used by doctors to help them plan treatment and operations including biopsies, surgeries, and radiation therapy.
⦁ CT scans may be compared by doctors to see if specific therapies are effective.
What Are the Negative Consequences?
The contrast materials can cause allergic reactions in certain persons. The majority of the time, the response is modest. Itchy skin or a rash are possible side effects.
In a small number of cases, the dye can cause a life-threatening response.
As a result, your health care provider may want to keep an eye on you following your CT scan for a while. Tell your doctor if you have any drug, seafood, or iodine allergies.
If you have diabetes and are taking the medicine metformin, let your doctor know.
They'll tell you if you need to cease taking your prescription before or after the surgery.
