Information for Scheduling the Exam
1. Fasting beginning 2 hours
prior to arriving. However, the
patient can take all medications as usual with small sips of water.
2. Patient should arrive 2
hours prior to their appointment time for registration and for the
administration of oral contrast.
3. Oral contrast is Volumen
beginning 1 hour before scanning. Drink 1 bottle (450 ml each) every 20 minutes
for a total of 3 bottles (i.e. a total of 1350 ml).
4. If the patient has outside
prior exams and reports, the patient should bring them to their MRI appointment
for comparison review.
5. There are no post
instructions after the MRI study. The patient can eat and drink accordingly.
Information for MRI Technologists
Background
- Surface Coil
- Philips Achieva- SENSE Body coil,
centered on umbilicus.
- GE Optima 450W- Torso Coil
- Siemens Espree- Use 2 contiguous
anterior coils (upper & lower abdomen).
i. NOTE: For the Siemens
Espree, separate series of the upper and lower abdomen need to be performed so
that the upper and lower abdomen, respectively, are isocenter.
- Prone
position is preferred. Note that images should be corrected and sent
to iSite PACS oriented supine.
- To avoid wraparound artifact, the
patient’s arms should be place superior to the surface coil, preferably above the head. If
the patient cannot tolerate this, the arms should be placed as close to
the body as possible.
