摘要:

Musculoskeletal ultrasonography (MSUS) has been refined by improved examination techniques and higher frequency transducer technology. Sonography is the modality of choice in the screening of tendon disorders. The accuracy in diagnosing tendon lesions has improved with better understanding of the sonographic anatomy and the pathophysiology of tendons. The sonographic appearance of tears, tendon dislocations, tendinitis, tenosynovitis, insertion tendinopathy, ganglion cysts, and bursitis is described. Normal variants that mimic tendon disease are shown. The tendons of the shoulder, elbow, wrist, hand, knee, ankle, and foot are considered.

摘要:

Because of the results of the North American Symptomatic Carotid Endarterectomy Trial (NASCET), there is increasing emphasis on screening for carotid atherosclerotic disease. There has been a long history of utilization of duplex sonography, combining ultrasound imaging and pulsed-gated Doppler in this regard. Refinements in duplex sonography, including the addition of color Doppler, have solidified the role of carotid ultrasound in this regard. Carotid ultrasound is an accurate method for assessing carotid stenosis; it has a sensitivity and specificity approaching 90% for stenoses >50%. In addition, this technique is able to evaluate plaque morphology, carotid dissection, and neck masses. Given the accuracy, absence of morbidity, and low cost of carotid ultrasound, it is unlikely that it will be replaced by competitive modalities such as magnetic resonance angiography (MRA) in the near future.
