The suprasternal notch view is a valuable tool for assessing the aorta and identifying signs of thoracic aortic dissection. Proper technique is essential to obtain a clear image and improve diagnostic accuracy.
Steps to Obtain the Suprasternal Notch View:
Position the Patient:
Ideally, place the patient in a supine position.
If the patient cannot tolerate lying flat, the scan can be performed with the patient in an upright position.
Probe Selection & Orientation:
Use a phased array probe in cardiac mode.
Direct the probe marker slightly toward the patient’s left shoulder (or right hip if using abdominal mode).
Optimize Patient Positioning:
Ask the patient to extend their neck to improve visualization.
Having the patient rotate their head to the side may further enhance imaging.
Placing a rolled towel under the shoulders can help achieve optimal neck extension.
Probe Manipulation:
Angle the probe inferiorly toward the chest.
Adjust the depth to clearly visualize the aortic arch.
