The radiation involved with CT may result in an increased lifetime risk of mri Magnetic field and radio frequency pulses surround the entire body, or a specific part, to create an image Best for showing soft tissues, such as muscles, ligaments, and internal organs MRI scans are more susceptible to motion artifacts than CT scans. The type of anatomy the health care provider is trying to visualize may affect their decision to order an MRI or a CT scan. For example, anatomy that contains calcium or air may not be visualized as well on an MRI scan, as compared to a CT scan. When describing findings on MR, we use words that refer to signal intensity. "Attenuation" used in CT does not apply in MR. However, like CT, abnormalities are described by their relationship to the intensity of a reference structure (brain tissue, CSF etc.).

This likely reflects the increased conspicuity of the mesentery on CT enterography and suggests that mural fe … CT (computed tomography) and MRI (magnetic resonance imaging) are both used to diagnose and stage cancer. Many people do not know the difference between the two methods or why one might be selected over the other.

The biggest difference is that MRIs (magnetic resonance imaging) use radio waves and CT (computed tomography) scans use X-rays. Where MRI really excels is showing certain diseases that a CT scan cannot detect.

A 4D image is a 3D image with the additional dimension of time. This CT could allow 0.5 mm true isotropic voxel data to be acquired much faster than the present 16-channel MDCT. MR imaging is rapidly advancing.
