Which view best visualizes the RCA from proximal to mid segments?

• A. LAO view
• B. RAO cranial view
• C. Lt Lateral view
• D. LAO caudal view

Answer: (A)

The left anterior oblique projection best visualizes the right coronary artery from proximal to mid segments because it aligns the imaging plane with the course of the RCA along the right atrioventricular groove. This view minimizes overlap with the left coronary system and reduces foreshortening, allowing a longer, clearer view from the origin near the aortic root down through the proximal and mid portions of the RCA. Other views tend to superimpose or shorten the RCA, making it harder to follow along its entire proximal-to-mid path.
