When performing a lateral projection of the patella, which statement is true?

• A. Image receptor must be placed in the bucky tray.
• B. Leg is rotated 45 to the affected side.
• C. Technique is reduced to prevent overexposing.
• D. Inferior-superior axial position is most frequently used.

Answer: (C)

In a lateral patella view, the main idea is to use the lowest exposure factors that still yield a diagnostic image, because the patella is a small, high-contrast structure and excessive technique can wash out bone detail and increase the dose without improving image quality. So the best choice is to reduce technique to prevent overexposing. Positioning also matters: this view requires a true lateral with the knee flexed so the patella sits in profile and the patellofemoral joint is clearly demonstrated. Rotating the leg or misaligning the patella would blur or misplace the structure, reducing diagnostic value. The inferior-superior axial (tangential) projection is a different view used specifically to evaluate the patellofemoral articulation from below, not the lateral patella projection. While using the bucky tray can be common to take advantage of a grid, the key point for this view is accurate lateral positioning and appropriate exposure, not a fixed requirement about receptor placement.
