Pulmonary ventilation/perfusion scan?

1 Answer

Answer :

DefinitionA pulmonary ventilation/perfusion scan is a pair of nuclear scan tests. These tests use inhaled and injected radioactive material (radioisotopes) to measure breathing (ventilation) and circulation (perfusion) in all areas of the lungs.Alternative NamesV/Q scan; Ventilation/perfusion scan; Lung ventilation/perfusion scanHow the test is performedA pulmonary ventilation/perfusion scan is actually two tests. These tests may be performed separately or together.During the perfusion scan, a health care provider injects radioactive albumin into your vein. You are placed on a movable table that is under the arm of a scanner. The machine scans your lungs as blood flows through them to find the location of the radioactive particles.During the ventilation scan, you breathe in radioactive gas
