CT Scan: Preparation, Procedure, and Its Side Effects

 

CT scan is an imaging process that produces cross-sectional images of the human body and precisely represents body structures. The images are much more detailed than conventional X-rays and make it easier, for example, to find a tumor. However, the ct scan Mandurah examination is also comparatively expensive and exposes the body to a higher radiation level than the classic X-ray procedure. 

What is a CT scan? 

Like conventional X-rays, CT scan uses X-rays to make the inside of the human body visible, in contrast to MRI, where magnetic fields are used to create sectional images of the human body. This is achieved in a tunnel or gantry device - often referred to colloquially as a "tube." With a ct scan of Mandurah, the patient is driven into a rotating X-ray tube. This rotates around the patient lying down, sends out X-rays, and creates several thousand cross-sectional images per rotation. The body tissue attenuates the radiation and thus becomes visible. High-density tissue, such as bone, appears light in the images, while low-density tissue appears dark. 

Across from the tube are detectors that collect the X-rays. A computer then combines the individual images into one image. In contrast to conventional x-rays, a CT scan allows body structures to be displayed in high resolution without overlaying them. Since the inside of the body is recorded worldwide, three-dimensional recordings can also be displayed, allowing viewing from many angles. This makes it easier to diagnose a wide variety of diseases and injuries. CT scan Mandurah is used for tumor detection, to determine vascular diseases, or to identify fractures, joint diseases, and injuries. 

What are the side effects of a CT scan? 

With computed tomography, there are no direct side effects that result from the examination. Side effects can only occur because of the allocation of contrast media.

The following side effects can occur from contrast media: 

• Nausea
• A headache
• Itching
• Sweat
• Hyperthyroidism
• Impaired kidney function
• Consequences of radiation exposure  

Preparation and procedure 

The patient does not have to come to the CT examination on an empty stomach. Before the computed tomography, a thorough anamnesis and a consultation with the doctor take place. If a CT with a contrast agent is planned, certain previous illnesses and intolerances must be excluded. These include, for example, an over-or underactive thyroid, kidney dysfunction, and allergies to the contrast agent. In the consultation, patients also find out whether they have to be sober for the examination. If a ct scan Mandurah with contrast agent is performed, the patient either takes it orally as a drink or is administered via venous access.

For the computed tomography, the patient usually lies on his back on a mobile examination table. The patient is then moved into the tomograph together with the table. Depending on the application area, the patient is moved into the CT device, either entirely or only in the body's area to be examined. 

During the examination, the patient must lie as still as possible and hold their breath briefly when examining the lungs. This is because, like photos, movement affects the quality of the images. The less movement, the calmer the patient, the better the results of the ct scan Mandurah.
