Today, there are few who can say that he has never heard of an MRI or a CT scan. We’ve all heard of these two body imaging methods. But certainly many people don’t know the difference between these two methods and sometimes mistakenly move their scan name. In this article, we are going to say in simple language how MRI scans are different from CT scans.
CT scans and MRI scans are two different methods of medical imaging that create detailed images of the internal parts of the body, such as bones, joints and organs.
Doctors prescribe CT scans or MRI scans to help diagnose a range of diseases and anatomical conditions. Both types of scans have similar applications, but they produce images in different ways. The CT scan uses X-rays, while MRI scans use strong magnetic fields and radio waves.
In this paper, we will discuss the differences between CT scan and MRI scan as well as their use, methods and safety.
CT scans and MRI scans are two different ways to create detailed images of the inner parts of the body. Doctors can then analyze images to detect abnormalities such as bone fractures, tumors on limbs or joint damage.
Some people call CT scans as CAT scans, which stands for Computed Tomography. During the CT scan, the person lay on a large X-ray machine called a CT scanner. The device sends images to the computer.
MRI stands for Magnetic Resonance Imaging. This type of scan uses radio waves and magnets to create images. During an MRI scan, the person lays in an MRI machine, a device that creates a constant magnetic field and uses radio waves to mutate water molecules and fat cells in the body. The MRI device also sends images to the computer.
CT scans are more common and less costly than MRI. However, MRI scans produce a better picture than a CT scan.
The applications of CT scans and MRI are very similar. CT scans are more common because it costs less and offers good body details. When your doctor needs to have more detailed images and read more of the body, he or she may prescribe an MRI scan.
Common applications of CT scans include checking or searching for:
Doctors usually use MRI scans to diagnose problems with bones, organs and joints, including:
In both scans, the person usually has to lie on the bed and then move inside the device. Patients must remain very inhabited and motionless during the scan so that the devices can take clear images. In both cases, technicians leave the room during the scan, but the person can talk to them via a voice communication link (intercom).
The CT scanner takes several X-ray images of the body from different angles. The good news is that CT scanners are almost silent. But in front of them, MRI scanners are very noisy, and a technician may suggest a listening person or headphones to reduce the sound.
CT scans and MRI scans are both very safe procedures. However, there may be minor risks, which vary between types of scans.
During a CT scan, the person receives a very small dose of radiation, but doctors usually do not consider this amount harmful.
CT scan uses ionized radiation that has the potential to affect biological tissues. According to the U.S. National Institute of Biomedical Imaging, the risk of cancer due to exposure to CT scan radiation is generally low.
The use of MRI and CT scans is very similar. Your doctor is based on a wide range of factors such as:
Medical reason for the scan
The level of detail required for images
Is a woman pregnant
Does a person have a classrophobia or other factors that may make mri scans difficult for them.
MRI scans create a more accurate picture of soft tissue, ligaments or organs. Problems that may be easier to see with MRI scans include soft tissue damage, ligament tears and disc herniation.
Doctors may use a CT scan to create a public image of a body part or to capture images of limbs or head fractures.
CT scans may not be safe during pregnancy, so doctors may prescribe mri scans or ultrasound scans instead.
MRI scans do not use radiation. However, they use strong magnetic fields. Individuals should notify their technicians to avoid potential risk if they have any type of medical implants, such as a pacemaker, insulin pump, or cochlear implant.
MRI scans produce loud noises, so people usually use earphones or headphones to reduce sound. People with lorophobia may find it difficult to tolerate MRI scanners, although there are many different types of open MRI scanners currently available to solve this problem. Because the duration of the MRI scan is much longer than the CT scan.
For both CT scan and MRI devices, your doctor may recommend using contrast paint to make images more transparent. Some people may react badly to certain types of color.
In general, it can be said that CT scans and MRI are two methods of imaging the internal organs of the body. They have similar applications but produce images in different ways. The CT scan uses X-rays while MRI scans use strong magnets and radio waves.
CT scans are generally good for larger areas, while MRI scans create a better overall picture of the tissue under investigation. Both have risks but are relatively safe methods. Depending on a range of factors, your doctor will advise the patient which scan is right for the individual.
The Specialized Website of Scan Teb has set up a panel for the convenience of patients to obtain medical scans and medical imaging so that patients can easily choose the date of the scan and their medical imaging center. Through the link below, you can choose the scan turn, the type of scan, the city you want to scan and the date and time of your scan.
