Types of radiography, Biology

Types of Radiography:

Positron Emission Tomography  (PET)

Uses high-energy physics and computer techniques to  study  lung function; useful for quantitative measurement of regional puImonary perhsion  and for studying ventilation-perfusion relationships.

Magnetic Resonance  Imaging

Magnetic Resonance Imaging (MRI) is the use of magnetic fields rather than radiation to create images of body  structures. MRI  is used much  like CT scan. The MRI  is more definitive than CT because  it  creates more detailed images of anatomic structures.

Fluoroscopy

Enables roentgenologist to view heart, lungs, and diaphragm in  the dynamic (moving) state.

Barium  Swallow

Outlines the esophagus and  reveals displacement of esophagus and encroachment on  its  lumen by  cardiac, pulmonary, and mediastinal abnormalities. The procedure has already been  discussed in BNSL-106.
