Ultrasound Imaging of the Abdominal Aorta: A Comprehensive Review
Nov 5, 2021 · Ultrasound imaging as an imaging modality for the abdominal aorta (AA) is highly valuable due to its high diagnostic yield coupled with advantages that include a noninvasive approach, cost-effectiveness, capability for point-of-care imaging, absence of procedure-related complications, lack of ionizing radiation and iodinated contrast use, and re...
Ultrasound Imaging of the Abdominal Aorta: A Comprehensive …
Jul 2, 2021 · In this review, we highlight the value of ultrasound imaging of the AA; review the anatomy, image acquisition, and measurement protocols; describe the AA's normal flow profile; provide data and illustrations of the various disorders that are detected and/or assessed by two-dimensional (2D), color, and spectral Doppler imaging; discuss the ...
With the patient in a supine decu-bitus position, scanning from the subcostal window to the level of the umbilicus allows visualization of the AA in its entirety. The longi-tudinal view is obtained in the sagittal plane with the transducer positioned along the long axis of the AA and its notch pointing to-ward the patient’s head (Figure 2, ).
Ultrasound Assessment of the Mesenteric Arteries
Jul 1, 2007 · Ultrasound visualization of the CA origin is best accomplished in the sagittal (longitudinal) plane, whereas its main branches are best seen in the transverse orientation. The CA arises from the anterior aspect of the aorta just superior to the SMA and bifurcates shortly after its point of origin (see Fig. 5 C ).
Duplex Ultrasonography of the Mesenteric Circulation
Jul 20, 2021 · An anterior-posterior midline approach, just below the xyphoic process, is used to obtain a sagittal scan of the proximal abdominal aorta. While the SMA is almost always appreciated in the sagittal plane, often the celiac artery and branches are best visualized in …
