PET/CT Preparation

DO NOT eat or drink (except water) for at least 4 hours before  your scan. If you take medication, take it with plain water.  Longer fasting and drinking plenty of water improves scan  quality.
The day before your exam avoid sugar, sweets like cookies, ice cream, fruit and soda, and do not eat shellfish such as mussels or oysters. It is recommended to eat  protein-rich foods such as chicken, nuts, eggs, cheese.

Diabetics should NOT take insulin or oral anti-hyperglycemic for   at least 4 hours prior to your appointment. Blood sugar levels will be checked and the procedure may have to be rescheduled  for blood sugar >200.

DO NOT  perform any strenuous activity for at least 24 hours before your appointment.  This includes exercise in any form.
