This physical phenomenon is related to change in wave frequency that is observed when the wave is moving or when it is reflected off a moving object. M-mode, color flow and spectral Doppler have higher outputs which can cause more heating at the site of examination. This study (JABTS BC-04 study) was aimed at confirming the usefulness of our CD diagnostic criteria. 16 Rose et al showed that in 3) On color doppler imaging, the mass shows increased vascularity and feeding vessels. The introduction of transvaginal ultrasound has improved visualization of normal ovarian function and ovarian tumors, and much work has been done to define and standardize ovarian tumor characteristics [3, 13–16]. It is useful to carry out a dynamic ultrasound of the gallbladder by changing the patient’s position. Recently, color-doppler ultrasound, spleen and liver stiffness measurements via point shear wave elastography have shown promise in potentially serving as non-invasive methods to assess for dysfunction[12-16]. 900.

Both spectral Doppler and color flow imaging depict mild flow disturbance as an increased range of velocities present within the sampled volume. The use of color and spectral Doppler is discouraged when imaging an embryo to avoid crossing a theoretical thermal index threshold. With this technique it became possible to directly "observe" blood flow within the heart. The epididymal tail is the most affected region, and reactive hydrocele and scrotal wall thickening are frequently present. Of these imaging methods, transcranial Doppler (TCD) is an interesting tool that provides a non-invasive, portable and radiation.
