MRI in Pregnancy
The following memo provides an interval update on the UW-Madison Department of Radiology policy for
scanning pregnant patients, including the use of gadolinium contrast agents, approved on 3/16/16 by the UW MRI Safety Committee.
MRI Guidelines
Gadolinium-enhanced MRI/A and Nephrogenic Fibrosing Dermopathy/Nephrogenic Systemic Fibrosis
This document describes modified screening procedures for mitigating the risk of nephrogenic
systemic fibrosis (NSF) in patients with renal failure undergoing gadolinium-enhanced MRI.
Guidelines for Non-Clinical Non-Research Use of MRI
Guidelines for Use of Consent and Waiver of Liability Form for Non-Clinical, Non-Research, MR Exams.

Anxiolytics – Claustrophobia Anxiety Prophylaxis for MRI
Recommendations for patients who may experience claustrophobia during an MRI scan and require prophylaxis,
File: MRI-anxiolytics.pdfGuidelines for MRI in Patients with GI Clips
The purpose of this memo is to provide an update on the status of pre-MRI safety screening in patients who may have had hemostasis clips placed during endoscopy or colonscopy. The concern is that torqueing of a ferromagnetic hemostasis clip
in a strong magnetic field could lead to bleeding or injury at the site of biopsy/polypectomy.
Ferumoxytol Guidelines
The purpose of this document is to establish departmental guidelines for administration of ferumoxytol as a contrast agent for patients undergoing MRI.

The purpose of this document is to establish a systematic approach for safely performing MRI exams of patients with metallic implants of uncertain identity. In all MRI facilities, a recurring challenge occurs whereby MRI safety screening procedures identify a patient with an implanted metallic object of uncertain/unknown identity. Despite the best attempts of the MRI safety team, there are many situations where accurate identification of the implant cannot be determined.

The purpose of this memorandum is to describe the appropriate use of pulmonary MRA for the diagnosis of pulmonary embolus in patients with dyspnea and/or chest pain, including the appropriate use of pulmonary MRA in pregnant patients.
