How To Scan The Uterine Artery | Doppler Ultrasound Probe Positioning | Transducer Placement USG Patient Positioning: The patient should be lying in the supine position Probe Selection: Choose a curved array transducer, commonly referred to as a "convex" or "abdominal" probe. A frequency of 2-5 MHz is typically used for transabdominal imaging. Probe Placement: Place the transducer on the lower abdomen, just above the pubic symphysis, with the probe marker oriented towards the patient's head. Sweep the probe side-to-side and up-and-down to visualize the uterus in both the sagittal and transverse planes. Identifying Uterine Arteries: The uterine arteries are usually identified as they cross over the external iliac arteries. They can be seen as pulsatile vessels on color Doppler, at the internal cervical os, the junction between the uterine body and cervix. The uterine arteries are located on either side of the uterus, so visualizing the uterus itself can help identify the position of these vessels. The uterine arteries run along the cervix, so identifying the cervix can be a useful landmark. Color Doppler can be used to distinguish the uterine arteries from surrounding structures. The uterine arteries show pulsatile blood flow, which can help differentiate them from nearby veins. Doppler Imaging: To evaluate blood flow, switch to Doppler mode. Place the Doppler sample volume over the uterine artery, and adjust the scale to capture the pulsatile flow. Measure peak systolic and end-diastolic velocities, as well as the resistance index (RI) and pulsatility index (PI) if required. Sampling Gate: 2mm Angle Of Insonation: Less than 30 degrees 3 consecutive waveforms are sufficient for spectral doppler evaluation #uterinearterydoppler #uterineartery #uterinearteryultrasound
