Consider the following regarding the differences between CT scan and MRI.

1. A computed tomography (CT) scanner is a good tool for examining tissue composed of elements of a higher atomic number (such as bones) than the tissue surrounding them. MRI, on the other hand, is best suited for soft tissues.
2. MRI is also best suited for cases when a patient is to undergo the exam several times successively in the short term, unlike CT which exposes the patient to the hazards of ionizing radiation.

Which of the statements is/are correct?

A computed tomography (CT) scanner uses X-rays, a type of ionizing radiation, to acquire images, making it a good tool for examining tissue composed of elements of a higher atomic number than the tissue surrounding them, such as bone and calcifications (calcium based tissues) within the body. MRI, on the other hand, uses non-ionizing radio frequency (RF) signals to acquire its images and is best suited for soft tissue. (Hence, statement 1 is correct.) MRI is also best suited for cases when a patient is to undergo the exam several times successively in the short term, because, unlike CT, it does not expose the patient to the hazards of ionizing radiation. (Hence, statement 2 is also correct.)
