Why do we do a left lateral chest?

This will allow radiographers/imaging technologists to image with the side of interest against the image receptor, hence reducing any magnification from an increased SID. Otherwise, a left lateral view is the default and preferred side as it demonstrates better anatomical detail of the heart.

Why is it important to perform a left lateral as part of the routine chest study?

Why is it important to perform a left lateral as part of the routine chest study? It reduces magnification of the heart.

Which is the most preferred standing chest xray view?

Posterior-Anterior (PA) projection The standard chest radiograph is acquired with the patient standing up, and with the X-ray beam passing through the patient from Posterior to Anterior (PA). The chest X-ray image produced is viewed as if looking at the patient from the front, face-to-face.

What is the most optimal position of the patient for examinations of the heart and lungs?

Positioning the patient The optimal position for chest auscultation is sitting in a chair, or on the side of the bed. However, the patient's clinical condition and comfort needs to be considered during the examination and some patients may only tolerate lying at a 45° angle.
