For imaging a transplanted kidney, which positioning is correct?

The correct positioning for imaging a transplanted kidney is supine anterior. This position allows for optimal visualization of the transplanted kidney, which is typically placed in the iliac fossa on the right or left side of the abdomen, below the native kidneys. By having the patient in a supine position, the technologist can obtain a clear view of the transplanted kidney and the surrounding structures while minimizing any potential artifacts caused by positioning.

In this orientation, the patient lies flat on their back, which helps in centering the kidneys' imaging plane directly over the detector for accurate acquisition of the images. Additionally, an anterior view provides excellent access to the relevant anatomical landmarks and allows for proper alignment with the imaging equipment.

The other positioning options may not provide adequate visualization or could introduce oblique angles that complicate interpretation of the images. The upright positions, for example, might not properly align the image capture area with the implanted kidney's position, leading to difficulties in assessing its function or any possible complications.
