Description
Estimated cost for Color Doppler Ultrasound of the Neck Vessels at general public hospitals in China is about ¥140-320, and at Grade 3A hospitals about ¥200-400, varying by hospital tier and region.
Main Uses
The primary purposes of a Color Doppler Ultrasound of the Neck Vessels include: 1. Evaluating the presence and degree of carotid artery stenosis, 2. Assessing the risk of stroke, 3. Monitoring the progression of atherosclerosis, 4. Guiding treatment decisions for vascular diseases, 5. Preoperative assessment for carotid endarterectomy or stenting, 6. Investigating causes of dizziness, syncope, or transient ischemic attacks (TIAs).
Normal Range
For a Color Doppler Ultrasound of the Neck Vessels, normal ranges typically include: Intima-media thickness (IMT) <1.0 mm, no plaques or stenosis, and blood flow velocity within expected parameters for the carotid and vertebral arteries. Normal peak systolic velocity (PSV) in the internal carotid artery is usually less than 125 cm/s, and end-diastolic velocity (EDV) is less than 40 cm/s.
Low Values - Possible Causes
血管狭窄或闭塞、低血压状态、心脏泵血功能减弱、严重贫血、脱水
High Values - Possible Causes
High values, like increased blood flow velocities, may indicate: 1. Atherosclerotic plaque causing arterial stenosis, 2. Post-stenotic dilatation, 3. Increased cardiac output, 4. Hyperdynamic circulation states (e.g., hyperthyroidism), 5. Collateral vessel development in response to chronic arterial obstruction.
