Why the study?
Does suprasternal ultrasonography accurately measure the diameters of the aortic arch, right pulmonary artery, and left atrium compared to angiography in healthy and diseased subjects?
Does suprasternal ultrasonography accurately measure the diameters of the aortic arch, right pulmonary artery, and left atrium compared to angiography in healthy and diseased subjects?
Suprasternal ultrasonography is a reliable, non-invasive method for measuring the diameters of the aortic arch, right pulmonary artery, and left atrium, demonstrating excellent correlation with angiography.
No takes yet. Share an insight, caveat, or question.
Should not yet change aortic arch measurement practice; leaves open prospective validation against angiography.
Barry B. Goldberg (1971) studied this question.
