How do they do a lung vq scan on a person?
A doctor has provided 1 answer
Two steps procedure: A lung scintigraphy has two components. The ventilation part (v of v/q) which consists in inhalation of 99mtc-gaz or aerosols and the perfusion part ( q of v/q) which involves the intravenous injection of 99mtc-maa which are used to see the perfusion of the lungs. Usually a lung scan is performed to detect pulmonary emboli ( blood clots in the lungs) or to perform a preoperative evaluation
