Ultrasound is a non-invasive imaging technique that uses ultrasound without X-rays to generate images. The advantages of ultrasound are; Its low cost when compared to MRI or computed tomography, its high resolution and dynamic character to make a detailed diagnosis of the superficial anatomical structures and moving joints. It guides interventions such as infiltrations, puncture, wash-out and aspirations of some calcifications. Ultrasound coupled with Doppler provides important information about, the vascularisation of the tumor and inflammatory lesions, arterial and venous circulation and allows the evaluation of valves and heart function.
