How images are obtained  
 

MRI images are displayed in shades of gray, like radiographs and CTs. The shade of gray that a given structure appears on MRI will vary with the MRI technique used to obtain the image. This will be discussed later in this module.

Images can be obtained directly in the axial, coronal, or sagittal plane. Like CT, axial images are viewed as though looking at the patient from the foot towards the head, placing the right side of the patient on the left of the image. Like radiographs, coronal images are viewed as though looking at the front of the patient, placing the right side of the patient on the left of the image. Sagittal images are viewed such that anterior is on the left of the image and posterior on the right.
