Answer:
True
Explanation:
In medical imaging, particularly in mammography, it is generally desired that the shadow of the vertical edge of the compression paddle should not be visible on the image. The compression paddle is used to flatten and spread out breast tissue, providing a clearer and more uniform image. If the shadow of the paddle edge is visible on the image, it may obscure details and affect the diagnostic quality of the mammogram. Proper positioning and technique are crucial to ensure accurate and clear images in breast imaging.
