We use lung scintigraphy to examine both pulmonary circulation and pulmonary ventilation. This method is considered the most sensitive diagnostic procedure for detecting a pulmonary embolism.
During the exam, two images of your lungs are captured: The visual scan of pulmonary circulation is completed in the first step. The distribution of inhaled air in both lobes of the lung is observed. To do this, you will take four or five breaths of a special air through a system of hoses; the air contains a low concentration of radioactive particles. The gas has no side effects whatsoever and will in no way adversely affect your well-being.
The gamma camera then takes a three-dimensional, high-resolution image of the pulmonary ventilation. The three-dimensional technique thereby further enhances the accuracy of the method and allows us to make an even more detailed diagnosis.
In a second step, radioactive albumin particles are administered to you intravenously. The gamma camera circulates around your chest a second time and detects the location of the albumin in your pulmonary vessels. It is thus possible for us to make a high-resolution, three-dimensional image of the pulmonary circulation. The examination takes approx. 45 minutes.
