CT Scan

Empowering Diagnosis

With CT Scan

Computed Tomography (CT) scan, also known as Computed Axial Tomography (CAT), is a medical imaging technique that utilises X-ray technology to create a detailed cross-sectional images of the body. CT scan offers comprehensive and accurate insights into the internal structures, organs, and tissues, that enable healthcare professionals to screen, monitor, and diagnose various medical conditions to administer accurate and timely treatment for better patient care. Advancements in CT technology continually improve and enhance image quality, reduce the need for higher radiation dosage, and improve patient care and comfort.

Overview of the Key Aspects of CT Scan

Types of CT Scanners

There are various types of CT scanners available in the field depending on the types of screening and diagnosis needed; including conventional CT, spiral CT, and multidetector CT. These scanners allow for continuous scanning, improved imaging quality, faster scans, and higher resolution images ensuring a better patient outcome.

Procedure: 

●       During a CT scan, patient is made to lie on a table equipped with motors that can slide into the circular opening of the CT scanning machine.

●       It is imperative for patients to remain still during the scanning procedure to avoid blurry images and improper imaging.

●       Patients may be asked to remove metal objects, accessories, or anything that may cause an hindrance during the scanning process.

●       The machine deploys a series of X-rays around the body of the patient to capture images from different angles.

●       It is a relatively painless and quick process.

●       The acquired images are then reconstructed into detailed images through specialised software to identify and assess any abnormalities or complications.

●       The procedure takes 15 minutes to one hour depending on the indication.

●       In cases where detailed scanning is required, a contrast dye may be administered through an intravenous line.

Benefits of CT Scan

●       Painless and relatively quick

●       Generates more detailed imaging as compared to X-rays

●       Effectively screens and monitors conditions related to head, neck, shoulders, spine, and abdomen, among others

●       Can be used to diagnose infections, muscle disorders, tumors, internal injuries, and cardiovascular diseases

●       Often used to guide procedures, surgeries, biopsies, and targeted treatment methods

It is important for the patients to inform their healthcare providers if they have any medical conditions or pregnancy related concerns to avoid aggravation of complication through the use of ionizing radiation or dyes. In addition, patients should refrain from wearing any accessories or metal products during the scan to avoid any risks during the procedure. If patients have any allergies, they should inform the healthcare providers to avoid allergic reactions and complications to the contrast dyes so that the radiologist can scan without the contrast. If contrast dyes are used, the patient is advised to drink a lot of water to remove the dye from the body.
