Why is an oblique angle sometimes preferred in ultrasound examinations?

An oblique angle is preferred in ultrasound examinations primarily because it improves visualization of structures that may not be well-centered or easily viewed with the standard longitudinal or transverse planes. By utilizing an oblique approach, sonographers can angle the transducer in a way that allows them to access and visualize anatomical structures from different perspectives. This can be especially beneficial in assessing complex anatomical regions, where certain structures might be overlapping or obscured in standard views. It enhances the ability to differentiate between adjacent structures and improves the overall diagnostic capability by providing more comprehensive images of the target anatomy.

This technique is particularly important in ophthalmic sonography, where precise visualization of the eye and surrounding structures is critical for accurate diagnosis and management of various conditions.
