Merrill's Atlas of Radiographic Positioning & Procedures Ch. 5 When doing the AP projection, neutral rotation, where does the CR enter? - ANS 1 in Inferior to the coracoid process Describe the epicondyles of the humerus when the patient is in position for the AP shoulder projection? - ANS Parallel to the IR Describe the position of the hand when the patient is positioned for an AP shoulder, internal rotation - ANS Hand is pronated until the the posterior aspect of the hand rest against the thigh What are the two preferred exposure/ breathing methods for the transthoracix lateral projection of the shoulder? - ANS 1. Long exposure, full inspiration 2. Long exposure, shallow breathing What is the main evolution criterion for evaluation of the scapular Y projection? - ANS No superimposition of the scapular body over the bony thorax What change must one make in the routine if the patient must be in the posterior oblique position for demonstration of the lateral scapula? - ANS Use an SID of 72 in Describe the position of the hand when performing the supine tagential projection for the intertubercular groove. - ANS externally rotated until anterior aspect is facing forward Describe the central ray, direction and degree of angulation fot the AP axial projection of the clavicle on the supine patient. - ANS 30 degrees cephalic Describe the D&D for the PA Axial projection of the clavicle. - ANS 30 caudal What is the main evaluation criterion for the AP projection of the scapula? - ANS Lateral portion of the scapula is free of superimposition of the ribs List for of the important and unique guidelines for demonstration of the AC joints - ANS 1.
