Abstract

Starting Carotid Ultrasonography: Patient PositionFor carotid ultrasonography, there are two options for the relative position between the patient and examiner.One is the overhead position, in which the examiner sits beyond the patient's head beside the end of the examination table and use two hands for ultrasonography.In this position, the examiner should use his right hand for the right carotid artery and use his left hand for the left carotid artery.The benefit of this position is that the examiner can use both hands and there are plenty of positions possible for the ultrasonography probe.The sonic window can be made wider and offers a clear view of the carotid artery especially from the posterolateral projection.The examiner should be familiar with using both hands, which requires some practice.Another position is the usual lateral sitting position, which is used for most other ultrasonography examinations.The examiner uses his right hand for both carotid arteries.This position makes it easy to control the machines.However, the right posterior projection is a bit more difficult.Between these two choices, the overhead position for Doppler ultrasonography of the carotid artery is recommended.A pillow is not necessary.In fact, it produces a poorer window for the carotid artery.The optimal patient head position is tilted about 45° away from the artery being examined.The neck of the patients should be relaxed.Contractions of the sternocleidomastoid muscle cause poor sonic penetration and make positioning of the probes difficult.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
