Stumped on a Crossword? Try Decoding This CAT ___ Puzzle!

The crossword question is asking for a four-letter word that completes the phrase “CAT ___“, with the additional hint that it is an alternative to M.R.I. Based on this information and knowledge of medical imaging technology, we can determine that the answer is “SCAN“. An M.R.I. (magnetic resonance imaging) is a type of medical imaging test that uses magnets and radio waves to create detailed images of the body, while a CAT (computed tomography) scan uses X-rays to generate images. Therefore, the phrase “CAT ___” is completed by “SCAN“, as it is another type of imaging test that can be used instead of an M.R.I.”
