Seminars in Ultrasound, CT and MRI, 1999
This article reviews gray-scale and Doppler evaluation of the adexae and endometrium. Color Doppler is useful in distinguishing between cystic and solid masses. However, spectral Doppler is of limited utility in improving the gray-scale morphologic impression of a mass being either benign or malignant.

Ultrasound in Medicine & Biology, 1990
Doppler spent more than twelve years in Prague, during which time he not only produced the majority and the most famous of his scientific works, but also married a devoted wife who bore him five children during their stay in the golden city. It is therefore not out of place here to take a brief look at Christian Doppler, not so much as a scientist, but

Tissue Doppler echocardiography
Current Opinion in Cardiology, 1999Tissue Doppler echocardiography (TDE) is a relatively recent addition to the diagnostic ultrasonographic examination. This is similar to routine Doppler ultrasonography to assess blood flow, but technologic features focus on lower velocity frequency shifts. Two techniques are used to assess myocardial function: pulsed TDE and color-coded TDE.

Doppler, Inertial, and Doppler-Inertial Techniques
Navigation, 1964The flight characteristics of the supersonic aircraft are such that strong recommendations have been made for self-contained, accurate navigation and flight stabilization equipment. This paper discusses three types of equipment that can supply the required information: Doppler radar navigation systems, inertial navigation systems, and combined Doppler-
