CONCLUSION: Blood flow in the appendiceal wall or right lower quadrant mass on color Doppler US scans suggests. whilst ensuring a sweep speed of 100 mm/s is used in stenosis. Both groups were diagnosed by color Doppler ultrasound. Seventy-six patients were diagnosed with hyperthyroidism based on clinical and laboratory data at our hospital. Both color and spectral Doppler imaging should be performed at favourable Doppler angle ≤ 60°. Testicular torsion can be complete, partial, or intermittent. Color Doppler images from an apical 4-chamber view. In the case of ultrasound colour flow imaging (CFI) (known also as colour Doppler imaging), a colour map depicting movement is superimposed on the PE image (figure 2). 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. Acute appendicitis was identified in 34 of 39 patients (87%) on color Doppler US scans with a sensitivity of 87%, specificity of 97%, and accuracy of 93%.
