Pulmonary ventilation visualization

Pulmonary ventilation visualization is a diagnostic imaging modality rather than a therapeutic molecular target, used to assess the spatial distribution of airflow within the lungs (StatPearls, NBK442017). It encompasses various techniques, such as ventilation-perfusion (V/Q) scintigraphy and hyperpolarized gas MRI, which are essential for identifying regional ventilation defects in diseases like chronic obstructive pulmonary disease (COPD), asthma, and pulmonary embolism (NIH, Lung Imaging). While not a protein or enzyme that drugs bind to for therapeutic effect, it serves as a critical functional biomarker for evaluating the efficacy of respiratory treatments in clinical development (Radiology, 10.1148/radiol.2021210141). The process typically involves the inhalation of contrast agents or radiopharmaceuticals, such as Technetium-99m DTPA or Xenon-129, which allow for the quantification of lung impairment (PubMed, 33872043). Consequently, this visualization is a vital tool for patient stratification and monitoring disease progression in pulmonary medicine.
