SPECIFIC CLINICAL CONTRAINDICATIONS TO PET/CT INCLUDE: Pregnancy or suspected pregnancy
Clinical contraindications rendering the patient medically unfit to undergo the scan include:
Chest drains in situ, Influenza, Chickenpox (Varicella Zoster Virus), Measles (Rubella), Mumps, Clostridium Difficile (may only be scanned at static
centres), Whooping cough (Bordetella pertussis), Active Shingles (Herpes Zoster), Diphtheria (Corynebacterium diphtheriae)
Additional physical and technical contraindications to PET-CT include:
Inability to cooperate with the scan process - For instance, inability to lie relatively still for 1-2 hours and to lie supine for 30-60 minutes
Blood Glucose Level - If the patient’s blood glucose level is outside the ARSAC certificate holder’s agreed limits. In patients with diabetes this must be
adequately
controlled prior to attendance for the PET-CT scan. Uncontrolled blood glucose levels may result in sub-optimal or undiagnostic image
quality and therefore in these circumstances the patient’s appointment may be cancelled and re-scheduled for an alternative date when
diabetic control has been established
Chemotherapy/Radiotherapy - If the patient’s appointment date is outside the ARSAC certificate holders agreed time limits
Patient body habitus above scanner dimensions - Scanner Bore Diameter 70cm (distance from scanner bed to roof of scanner approximately 50cm).
If it is uncertain if a patient’s body habitus will prevent us from proceeding with the scan the patient may be invited to attend the scanner prior to their
appointment date to undergo a trial run through the scanner gantry
