Acute torsion of a wandering spleen: diagnosis by CT and duplex Doppler and color flow sonography.

Orbital Varix

A case of orbital varix is presented in which the lesion is well demonstrated by color flow Doppler sonography. Correlation is made with CT and MR studies. We believe that color flow sonography should be used as the initial screening test in cases of suspected orbital varix.

Techniques for color flow sonography of the lower extremity.

Color flow sonography permits noninvasive examination of the deep venous system in the lower extremity. In many patients, the modality is sufficiently accurate to serve as the sole diagnostic procedure for suspected deep venous thrombosis. Over 1,500 color flow sonographic examinations of the lower extremity have been performed at our institutions with various scanning techniques. For the inexperienced sonographer, we describe our current technique, which is easy, quick, accurate, and well tolerated by patients.
