Radiologic Technologist Practice Exam

For the optimum image of the right kidney during urography, what position should the patient be in?

1. Right posterior oblique (RPO)

2. Left posterior oblique (LPO)

3. Lateral

4. Supine

The correct answer is: Left posterior oblique (LPO)

To achieve the optimum image of the right kidney during urography, positioning the patient in the left posterior oblique (LPO) is the most effective choice. This position allows the right kidney to be more perpendicular to the X-ray beam, enhancing the visibility and detail of the anatomy being examined. When the patient is in the LPO position, the right kidney is better aligned for imaging, reducing superimposition of surrounding structures, thus providing a clearer view of the renal contours and any potential pathology. This positioning takes advantage of the anatomical layout, as the right kidney is typically situated slightly lower compared to the left due to the presence of the liver. This technique is also favorable in evaluating kidney morphology or any potential obstruction, making it a critical positioning strategy in urographic examinations. Other positions may not provide the same level of clarity or could obscure vital structures, leading to less diagnostic utility.
