Jennifer Worman is a fashion influencer. But this past November, she traded her usual luxury look for a hospital gown in downtown Chicago. She got a full-body MRI – something many celebrities have touted on social media in the last few years as the must-have test for early diagnosis. If you catch anything – no matter how minor – in your body, after all, that's better than not catching it, right?

Worman, 49, laid on a flat surface for the SimonONE test like a typical MRI, after draping on that gown and cleansing her system with an enema. A technician told her what to do (and how to breathe). Even though she doesn't love small spaces, she didn't feel claustrophobic as the machine scanned her organs. Her brain, her liver, everything from her head to her pelvis. Beep. Beep. Beep. The whole process too less than an hour, like laying down to take a nap.

Four days later, her phone rang. They found something. She needed a CT scan. Gulp. It revealed "a very tiny aneurysm," she says.

A neurologist examined it further, noting it was "small enough that there was no emergency."

Whew.
