Magnetic Resonance Imaging (MRI): Computer reformatted digital display of multiplanar images developed from the capture of radiofrequency signals emitted by nuclei in a body site excited within a magnetic field
Other Imaging: Other specified modality for visualizing a body part
Plain Radiography: Planar display of an image developed from the capture of external ionizing radiation on photographic or photoconductive plate
Ultrasonography: Real time display of images of anatomy or flow information developed from the capture of reflected and attenuated high frequency sound waves
