Description

Technegas is a specialized gaseous radiopharmaceutical agent used for diagnostic lung ventilation imaging. Its unique ultrafine aerosol properties allow for superior and stable distribution within the pulmonary alveoli, providing high-quality diagnostic images. This product is essential for nuclear medicine departments and radiopharmacies serving hospitals and diagnostic imaging centers globally for the evaluation of pulmonary embolism and other lung ventilation disorders. Technegas CAS NO 112263-77-1 represents a critical tool in modern respiratory diagnostics.

Application

• Pulmonary Ventilation Scintigraphy (V/Q Scan): Primary application for imaging lung ventilation, typically paired with a perfusion agent to diagnose pulmonary embolism.
• Diagnosis of Chronic Obstructive Pulmonary Disease (COPD): Used to assess regional lung function and ventilation defects.
• Pre-operative Lung Function Assessment: Evaluates ventilation capacity prior to lung resection surgery.
• Research & Development: Utilized in clinical studies investigating new applications for lung aerosol deposition and respiratory physiology.
• Quality Control in Nuclear Medicine: Serves as a reference standard in the development and validation of lung ventilation imaging protocols.
