Identify a true statement about grids used in mammography.

• A. Linear and Honeycomb
• B. Only linear grids exist
• C. All grids are honeycomb
• D. Grids are obsolete

Answer: (A)

Grids in mammography are used to improve image contrast by absorbing scattered photons that would blur details on the detector. There isn’t just one design; two common patterns are linear (parallel) grids and honeycomb grids. Linear grids have straight, evenly spaced lead strips, while honeycomb grids use a hexagonal pattern. Since both designs are used in practice, the statement that linear and honeycomb grids exist is true. Grids are not obsolete, and they aren’t limited to a single design, which is why the other options don’t fit: there are multiple grid patterns, and grids remain an important tool in optimizing image quality depending on factors like breast thickness and exposure setup.
