**8. Conclusion**

Refinements in technology continue to expand the capabilities and application of medical ultrasound in many clinical frontiers. One of the areas that has received significant acceptance is in its application to musculoskeletal and Neuro vascular disorders. This has further brought together a variety of clinical specialties such as orthopedics, vascular surgery, podiatry and physical therapy and rehabilitation medicine. The improvement in probe technology has allowed the development of ultra-fast high frequencies, with amazing results in spatial resolution, finer details, increased sensitivity and accessibility to obscure locations. The challenges of operator dependence and lack of standardized protocols have gradually been addressed due to increasing experience and applications by imaging experts [20].

Deployment of Doppler techniques such as Super micro vascular imaging, elastography, ultrafast Doppler and skilled maneuvers allow distinctive visualization of tissues such as joint capsular ligaments, tendons retinacula, fasciae and nerves all of which involve tiny mesenchymal structures whose diameters are in fractions of millimeters [11]. One more critical area of application is in the diagnostic evaluation of obscure masses [21]. These are essentially lesions in locations where conventional imaging modalities are less effective due to poor access. Such lesions include the perineum, vulva/labial regions, skin surfaces, abdominal walls and scalp [21]. The result is better diagnosis, improvement in patient navigation, quicker and easier treatment, less hospital stay, lower cost of health care and better prognosis. It is obvious that the future continues to hold better prospect for the ultrasound imaging of musculoskeletal systems.
