Which statement about the RT Vertebral artery waveform is NOT true?

The statement regarding the diameter being consistent with healthy vertebral flow is not true because in cases of pathology, such as stenosis or occlusion in the vertebral artery, changes in the diameter and flow characteristics can occur. In healthy vertebral flow, we expect a normal waveform with specific characteristics that indicate adequate blood flow. However, if the flow is disrupted due to an occlusion or significant stenosis, it would lead to an abnormal waveform and potentially a change in the diameter of the vessel.

Understanding the vertebral artery waveform is crucial for diagnosing vascular conditions. The nature of the waveform can provide significant insights; for instance, a disturbed pattern might indicate the presence of a lesion leading to compromised hemodynamics. Therefore, recognizing what constitutes a 'normal' waveform versus altered flow patterns aids clinicians in determining vascular health and diagnosing possible conditions.
