This is an abbreviation of computed tomography. X rays are used to create films in CT projection. X Ray is a high rays of energy that are not visible in the eyes. When the X -ray is over, it can be blocked by a cloth. The bone will resist the majority of x-ray. Thus, the white film contains bone parts or calcified details.
Depending on the number of X-rays, the computer program calculates the image of the fabric. The number of x -rays used in CT screening is much higher and can cause side effects. If CT is taken several times, it can cause cancer. The scanner indicates the axial appearance of the texture. Therefore, movies are usually two dimensions. CT now has a three -dimensional film reconstruction system.
MRI is an acronym for a magnetic resonance image. Magnetic waves are used (not harmful as x -play). MRI -Mashina looks like an external CT car. However, the mechanism is completely different. MRI -scrying offers better images on soft textures than CT. Images for brain and spinal cord images are better when checking MRI. MRI can be used during pregnancy because it is true. Because the effect of CT is not recommended to take it during pregnancy. Three -dimensional pictures are used as an MRI -MRIGRIAN
MRI (study on blood vessels)
Compared to CT, MRI requires more time. The patient should be in the machine tube longer. Thus, people who are afraid of the closed parts (claustrophobia) are afraid to face the difficulties in MRI. Computed tomography can be provided by passing. However, MRI requires the cooperation of patients to make a good movie. Simple CT does not require special training, but MRI should be prepared. Metal clamps (dental clamps) and metal details should be removed before the MRI intermediary. Because the metal substances are taken from the magnetic field formed in the car, the patient used in the body cannot receive an MRI -scrying with a metal clamp. MRI is more expensive than CT.
Thus, CT and MRI are a method of visualization for the photo. CT uses x -rai, which can be harmful, but MRI is safer. CT requires less preparation and bone details are clearly visible. The MRI should be easy to prepare for time and soft tissues. MRI offers the best 3D -reflected species than CT. MRI is safer during pregnancy, not CT. The MRI requires a metal environment, but CT does not need it.
