Found insideThis is particularly true in medical imaging. The result is that it is now virtually impossible to produce a "single author" book that can cover the field or even a subdivi sion of it. You will be asked to inhale a slightly radioactive gas and given an injection of slightly radioactive material. Diagnosis of pulmonary embolism is most commonly accomplished with CT angiography, although ventilation/perfusion scanning is sometimes required. Pulmonary embolism is caused by a blocked artery in the lungs. A ventilation/perfusion lung scan, also called a V/Q lung scan, or ventilation/perfusion scintigraphy, is a type of medical imaging using scintigraphy and medical isotopes to evaluate the circulation of air and blood within a patient's lungs, in order to determine the ventilation/perfusion ratio.The ventilation part of the test looks at the ability of air to reach all parts of the lungs, … A VQ scan is carried out in two parts.
