Anyone been for an MRI because of multiple fibroids/bulky uterus? Just wondering how claustrophobic the whole experience is, how long it generally takes and if your head is inside the scanner. I'm a bit anxious as I hate enclosed spaces. Also, do you have to remove wedding and engagement rings if they aren't magnetic? Mine have been stuck on my finger for the last 16 years and can't get them over my knuckle!
