As with most radiological procedures, there may be preparations that will be required to be done by you. Below are some preparations needed to ensure a successful and smooth NM scan appointment.
Appointment rescheduling
For Meckel’s scan and gastrointestinal (GI) bleed studies only
If you had gone for a barium study 5 days before your NM appointment, do call our appointment centre and reschedule as there may still be remaining traces of the barium contrast media used in the previous study in your body that may affect the accuracy of the NM examination.
For thyroid and parathyroid studies only
You should only do your NM Thyroid or Parathyroid scan at least 1 month after any Computed Tomography (CT) scans with radiological contrast. Do inform any of our staff and reschedule your appointment.
Fasting (For gastro-intestinal motility studies only)
You are required to fast for 4-6 hours before the scan.
Patient position
Majority of the scans will be performed with you lying in the supine position. There are some that may require you to stand during the procedure or may need you to be in a combination of positions.
Do discuss with your requesting doctor should you have difficulty in any of the above positions before scheduling an appointment.
Pregnancy
Do inform your doctor or any of our staff before scheduling an appointment should you be/ are unsure if you are pregnant.
Medications
For most NM scans, regular prescribed medications can be continued as per normal. However, if you are coming for a thyroid/parathyroid NM scan, some medications are required to be stopped prior to scan. You will be given more information about this when your doctor is scheduling your appointment.
