The boxed sets are great gifts. The pie and baking boxes are good for the holiday season pastries and whatnot, but the general cooking/grilling box sets are very good gifts for people who do those kinds of cooking. I use a lot of their herbs and the granulated garlic (both roasted and plain), but my favorite blends are Northwoods, Greek, and the Creamy Peppercorn (it’s listed as a dressing/dip mix, but I use it as the seasoning for pork chops).
MRI sometimes uses a non-radioactive contrast depending on what you’re trying to get images of. MRI is probably the safest imaging modality, but it’s very expensive, kind of difficult sometimes due to how long it takes, and isn’t useful for every kind of imaging that needs to be done.
