Cyclomedica is a radiopharmaceutical company providing clinicians with the ability to improve patient care outcomes. Cyclomedica is well-known for its Technegas Generator. For more than 30 years, Technegas is the leading technology for diagnosing pulmonary embolism. Technegas provides functional lung imaging through ventilation lung SPECT which now is an emerging diagnostic contribution to the clinical management of patients with airways diseases such as COPD and Asthma. The technology produces ultrafine dispersion of radioactive labeled carbon nanoparticles called Technegas which is inhaled by a patient. In as little as 3 to 4 breaths, Technegas allows multiple views and tomography imaging under a SPECT camera to diagnose various types of pulmonary and ventilation disorders.
