Exam Preparation

• A CDI representative will call you prior to your appointment to provide specific instructions, and review health and insurance information.
  
• Please bring previous imaging study results (x-ray, MRI, CT, etc.) such as reports, films, and CD-ROMS, if available.
  
• Please arrive 15 minutes early to verify your registration and health information.
  
• Please notify a CDI representative if there is a chance you could be pregnant.

During the exam – what to expect

• Your exam will take approximately 30 minutes.
  
• You will be given a list of instructions that you will be asked to sign and to follow for several days following the treatment.
  
• A radiologist specialized in nuclear medicine will talk to you about the treatment, instructions and answer any questions you may have.
  
• You will be given a capsule to swallow and asked not to have anything to eat or drink for 1 hour following the treatment.

After the exam – what to expect

• The radiologist prepares a diagnostic report to share with your doctor.
  
• Your doctor will consider this information in context of your overall care, and talk with you about the results.
  
• Most of the radioactivity passes out of your body in urine or stool. The rest simply disappear through natural loss of radioactivity over time.
