That’s so weird! My doctor and I were talking about that recently and I asked if anyone still uses metal and she said the last time she ever saw it was when she was in med school years ago. I hope they warm it up first!

It depends on the facility, and also the department.

Plastic are used once and throw away. The metals ones are sent to sterilization.

Radiology normally uses the metal ones and they come in several different sizes from 3, 4, 5, 6, and 7.5 inches.

7.5 is rarely used and it will turn some heads when you see how big it is in person.
