This is a non-contrast lung CT scan showing both perfusion and ventilation using a mathematical algorithm. The FDA recently cleared the perfusion portion of the CT:QV software from 4D Medical. The technology has been compared in studies to both nuclear and spectral and contrast enhanced CT. #RSNA2025 | Radiology Business

The respiratory process consists of three components. Ventilation, diffusion and perfusion. Ventilation consists of two parts: - Inspiration, which is the expansion of the chest with a negative intrapulmonary pressure when air flows into the thorax; and - Expiration, when the intrapulmonary pressure is higher than the atmosphere, air will flow out of the lungs. Diffusion is the process whereby gases move from an area of high pressure to low pressure. This includes during: - Internal respiration
