Answer 1

CT - Computed Tomography
MRI - Magnetic Resonance Imaging 

DIFFERENCES : 
CT is an invasive technique as it uses X-rays while MRI is a non invasive technique as it uses magnetic fields. 

USES :
CT gives 3 dimensional and sectional picture of any part of the body while MRI gives better contrast of softer tissues. MRI, however, cannot be used on patients fitted with pace maker and metal implants.
