As we continue our efforts to inspire excellence in imaging, this week we will feature another What’s Wrong with this Image blog. You can check out our previous vascular blogs from this series: Carotid Long Axis CCA Carotid ICA Prox As consultants, we review many vascular images, as we help our clients prepare for accreditation. In […]

Central venous pressure (CVP) or right atrial pressure (RAP) waveform tracings can oftentimes provide useful insight into a patient’s right ventricle
What’s wrong with this image? Modality: Carotid Vascular View: Color Right ICA Prox Measurement: RICA Prox – Peak/end diastolic velocity Answer: The angle is not parallel to the vessel. The image label is missing location (prox, mid, distal) Tips for correct angle placement: […]

Ultrasonography (US) of the carotid arteries is a common imaging study performed for diagnosis of carotid artery disease. In the United States, carotid US may be the only diagnostic imaging modality performed before carotid endarterectomy. Therefore, the information obtained with carotid US must be reliable and reproducible. Technical parameters that can affect the accuracy of carotid US results include the Doppler angle, sample volume box, color Doppler sampling window, color velocity scale, and color gain. Important factors in diagnosis of atherosclerotic disease of the extracranial carotid arteries are the intima-media thickness, plaque morphology, criteria for grading stenosis, limiting factors such as the presence of dissection or cardiac abnormalities, distinction between near occlusion and total occlusion, and the presence of a subclavian steal. Challenges to the consistency of carotid US results may include lack of a standard protocol, poor Doppler technique, inexperience in interpretation of hemodynamic changes reflected in the Doppler waveform, artifacts, and physical challenges. Hindrances in the classification of problematic carotid artery stenoses may be overcome by following a standard protocol and optimizing scanning techniques and Doppler settings. © RSNA, 2005
The renal veins are paired blood vessels that return blood back to the IVC. The left renal vein is the longer one and courses between the superior mesenteric artery and aorta. It is important to vi…
