Spatial resolution
The resolution of CT is superior to the resolution of magnetic resonance imaging (MRI), which is typically 1–2 mm for most sequences and more than adequate for most clinical applications of CT.
Does MRI have high spatial resolution?
It features full three- dimensional (3-D) capabilities, excellent soft-tissue contrast and high spatial resolution. Furthermore, MRI allows functional, diffusion and perfusion imaging to be performed.
Which modality has the lowest spatial resolution?
Spatial resolution of Ultrasound and Magnetic Resonance is more complex due to the physics of these imaging modalities. Of all the above modalities Nuclear Medicine has the lowest spatial resolution with PET/CT having a resolution of 2 mm.
