COLOR-CODED DUPLEX SONOGRAPHY (ANGIODYNOGRAPHY)

Colour coded duplex sonography is a relatively new method of diagnostic imaging. Compared with conventional duplex sonography it has advantages in respect of simplicity and speed in several applications. The main application of colour coded duplex sonography is for the detailed demonstration of a limited area. A comprehensive demonstration of blood vessels remains the province of angiography. Clinical applications include vessels in the neck, lateral soft tissue anatomy of the neck, arteries and veins in the extremities, haemodialysis shunts, transplanted kidneys and acute abnormalities in the scrotum. In the abdomen the method is of only limited application.
