- If Eovist is ordered, follow the Eovist protocol.
- The MRCP sequences must be performed BEFORE the Eovist administration. Otherwise, the dense contrast blacks out the MRCP sequences.
- Void before exam
- Send ADC maps
- FOV: do not include patient’s arms
- Scan on expiration.
- Monitor that patient is breath-holding. Breathe the patient slowly so they have time to follow instructions. Do not start scan until the patient has stopped breathing.
- Give 2L O2 if it will help with breath-holds UNLESS PATIENT HAS COPD OR ANOTHER REASON NOT TO GIVE O2.
