What does CFDI mean in PHOTOGRAPHY & IMAGING

Colour Flow Duplex Imaging (CFDI) is an ultrasound imaging technique used to visualize the blood flow within body vessels. It combines duplex scanning and digital colour flow mapping to provide an image of the blood vessel and its flow characteristics.

CFDI visualization works by using ultrasound signals to measure the size, velocity, and direction of blood flow in any given artery or vein. The signals are then used to generate a detailed map of the area being studied, providing insight into arterial or venous issues that may be present.

CFDI can be used to detect many different types of vascular conditions including occlusions, stenosis, thrombosis, emboli, irregularities in veins or arteries due to disease progression or trauma, as well as assessing shunt flow in bypass grafts or dialysis access sites.

The length of time needed for a CFDI scan depends on what area is being scanned and the complexity of the problem at hand. Typically it takes approximately 10-15 minutes for a full examination which includes multiple vessel segments imaged bilaterally.

A CFDI scan is usually considered safe but as with any medical procedure there are potential risks such as infections from bacteria carried by the patient's own bloodstream during examination due to handling probes etc., though these risks have been found to be rare in practice.
