Radiculography with non-ionic contrast medium: routine bed rest is unnecessary

Clin Radiol. 1984 Jul;35(4):287-8. doi: 10.1016/s0009-9260(84)80095-1.


In a prospective study into the occurrence of side-effects, 200 patients who had undergone iopamidol radiculography were randomly allocated into two groups, one being confined to bed for 24 h and the other allowed to be fully ambulant. We found that the incidence of side-effects was not increased by allowing the patients to remain ambulant and that headache and dizziness were significantly less frequent than in a comparable study in which we had used metrizamide.
