Value of ultrasound in the anatomical evaluation of the brachial plexus: correlation with magnetic resonance imaging.

Objective: To assess the accuracy of ultrasound in the visualization of the brachial plexus and to determine the value of the method in comparison with that of magnetic resonance imaging (MRI).

Materials And Methods: This was an anatomical study of the brachial plexuses of 20 asymptomatic adults (40 plexuses), comparing ultrasound and MRI in terms of their accuracy. In the ultrasound study, a high-frequency linear transducer was used, and a neurovascular coil was used in the MRI study.

Ultrasound of tropical and infectious diseases that affect the scrotum.

Ultrasonography of the scrotum permits assessment of testicular and extratesticular masses with high sensitivity. It can differentiate a variety of conditions involving the scrotum, testicles, and epididymis with similar clinical manifestations, including infectious and tropical diseases. The authors performed conventional and color Doppler ultrasonographic examinations in 76 patients who presented with scrotal pain, swelling, and/or tenderness.
