The procedure described by CPT® Code 78588 involves pulmonary perfusion imaging, which is a diagnostic test used to evaluate the blood flow to the lungs. In this procedure, the physician administers radioactive particles that are intentionally designed to be too large to pass through the capillaries within the lungs. This characteristic is crucial as it allows for the visualization of blood flow patterns and potential blockages. A specialized imaging camera is employed to track the distribution of these particles as they accumulate in the lung tissue. The accumulation of particles provides valuable information regarding the presence of pulmonary embolism, a condition where blood clots obstruct blood flow in the lungs. Additionally, this imaging technique assesses the overall ventilation of each lung, offering insights into the functional capacity of the pulmonary system. The combination of perfusion and ventilation imaging enhances the physician's ability to diagnose and manage various pulmonary conditions effectively.
