This procedure may also be used to determine blood flow to … This concept of a Doppler shift is used to measure blood flow velocity whereby the shift in sound-wave frequency is detected by the ultrasound transducer after encountering active blood flow. • Doppler US is used to detect moving blood cells or other moving structures and measure their direction and speed of movement. • Color Doppler US uses a computer to convert the Doppler measurements into an array of colors. A scrotal wall abscess may form as a complication from scrotal wall cellulitis (Fig. Pancreatic ultrasound can be used to assess for pancreatic malignancy, pancreatitis and its complications, as well as for other pancreatic pathology. Do you use ultrasound for suspected peritonsillar abscess (PTA)? Findings on three-dimensional ultrasound and power Doppler which have been associated with malignancy include vascular flow in the center of the mass (“central flow”), blood flow within septations and excrescences, and a complex appearance of the vascular architecture. Pelvic ultrasonography (US) remains the imaging modality most frequently used to detect and characterize adnexal masses. ... Urethral diverticulum / cyst / abscess. A tubo-ovarian abscess (TOA) typically presents as a complex adnexal mass with solid and cystic components, thick walls, hyperemia, and an indistinguishable ovary. Because sonography is not 100% sensitive, Color Doppler ultrasound findings may be normal (blood flow maintained) despite the presence of ovarian torsion.
