HIGH RESOLUTION ULTRASOUND OF THE JOINTS

Abstract
The rapid expansion of technical improvements of the ultrasound (US) transducers as well as in the software of the equipment has led to a new role of US in the assessment of the joints and other musculoskeletal structures (1-7). US provides useful information in assessing both the normal anatomy then a wide range of joint disorders. Although US is operator-dependent and has definite limitations in evaluating some intraarticular structures, it has several advantages over other imaging modalities including time and cost effectiveness, superior spatial resolution, and possibility to perform a dynamic examination in a patient comfortable position. The purpose of this article is to describe the possibilities of US in the evaluation of normal anatomy and main disorders affecting the joints. As for all imaging techniques knowledge of the normal anatomy and normal imaging appearance is a prerequisite to detect and characterize the different pathologic alterations. In the first part of this review we will describe the US anatomy of the different joint components. Then the US appearance of the most common joints disorders will be presented.
