Posterioranterior: Posterior anterior refers to entrance of xray beam posteriorly and exit anteriorly (PA). With anterior chest facing casette and proper distance of tube from patient, the least magnification of heart shadow occurs. Misinterpretation of enlarged heart is less likely to occur. Patient is standing for examination.
