Since the development of X-rays in the late 1800s, medical imaging technologies have advanced significantly. The CT scan, or computed tomography, is one of the most widely utilized imaging techniques today. Using X-ray technology, this non-invasive method creates precise photographs of the inside body components. However, what precisely takes place during a CT scan procedure, and how is it different from other imaging modalities like MRI?
The patient is placed on a table that glides into a device called a CT scanner, which has the shape of a doughnut. The scanner takes several images of the body from various angles using X-rays. The cross-sectional image that results from the computer’s combination of these photos can aid medical professionals in the diagnosis and treatment of a number of illnesses. For the early detection of cancer, bone fractures, and internal bleeding, CT scans are extremely helpful.
There are also portable CT scanners that may be helpful in an emergency or for those unable to travel to a hospital or imaging facility. However, depending on the features and specifications, the price of a portable CT scanner can range greatly, from $50,000 to more than $300,000.
Magnetic resonance imaging, or MRI, is another imaging technique that is frequently contrasted with CT scans. A strong magnetic field and radio waves are used in MRI to produce precise images of the inside organs. MRI uses no ionizing radiation, in contrast to CT scans, making it a safer option for some patients, such as expectant mothers. However, MRI procedures might cost more money and take longer to complete than CT scans.
Also brought up is body tomography, or body tom. As both terms refer to the same imaging technique, CT scans and this phrase are frequently used interchangeably. However, “body tomography” is a more precise word that denotes the use of CT scans to image the entire body.
An MRI procedure can be a scary or claustrophobic experience for those who are anxious or have a claustrophobia. The patient might be given a little sedative or prescribed medication to help calm their anxieties in such circumstances. Additionally, some imaging facilities use open MRI machines, which are less enclosed and may be more pleasant for people who are claustrophobic. Rarely, individuals may require general anesthesia in order to undergo an MRI.
In conclusion, imaging techniques like MRI and CT scans are crucial for both identifying and treating a wide range of medical disorders. Despite the fact that each imaging technique has benefits and drawbacks, doctors can select the best imaging technique based on the requirements and health of the patient. You should talk to your doctor or another trained medical practitioner if you have any worries or inquiries about having an imaging treatment done.
