V\/Q scanning has a high sensitivity of 96 &#8211; 97.4% for detecting perfusion abnormalities.<br \/>\nBut V\/Q scan being not very specific, its diagnostic utility is low. It can only be used as an initial screening test. Any abnormal test requires addition diagnostic imaging like CT (computed tomography) pulmonary angiogram, MRI (magnetic resonance imaging) or invasive (catheter based) pulmonary angiogram for establishing the diagnosis of thromboembolic pulmonary disease.<\/p>\n<p><a href=\"\/professional\/lung-ventilation-perfusion-scintigraphy-cardiology-mcq\/\"><strong>Back to question<\/strong><\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Lung ventilation-perfusion scintigraphy has a negative predictive value of nearly &#8212;
