PET Skull to Thigh

1. Indications:
   1. Tumor staging, therapy assessment, evaluation of recurrent disease
2. Preparation
   1. See attached Patient Preparation for PET scan guidelines
3. Equipment
   1. Biograph 40
4. Isotope administration
   1. Patient will receive 8-12 mCi of F¹⁸-FDG  administered intravenously in an establish IV line

1. Pediatric dose per nomogram (.15-3 mCi/kg minimum dose 1 mCi)

1. Imaging Parameters
   1. CT topogram to establish scanning limits
   2. CT scan for attenuation correction
   3. PET scan times will be determined from BMI/scan time chart.

1. Scan times maybe increased or decreased based on patients size, ability to cooperate and count rate.

1. Scanning protocol
   1. Technologist will make sure the patient is properly identified and followed all the patient preparations and blood sugar is below 180 mg/dl
   2. Technologist will place an IV catheter in the patient and inject the patient with the radiotracer followed by  10 cc of Saline in the intravenous line.
   3. The patient’s IV is removed and then the patient is placed in the PET uptake room for 60-90 minutes
   4. Patient will empty their bladder just prior to scanning
   5. All metal objects in the field of view are to be removed, changing into a hospital gown maybe necessary
   6. Patient is placed supine on the imaging table with arms extended over their head when possible and immobilized for optimal imaging
   7. Patient is scanned from eyes to mid thighs unless otherwise instructed.
2. Post processing/ Achieve
   1. Images to be created are the Fused Coronals, PET Coronals, Fused Axials, PET Axials, PET Uncorrected Coronals, PET MIP, and additional reconstructions at the request of the radiologist.
   2. Raw Data will be sent to Syngo Via
   3. Raw Data, created images, and patient CT dose will be sent to PAC’s system
   4. All worksheets ,scripts and patient records will be scanned into PAC’s
