TABLE 1

¹⁸F-FDG Radiation Dosimetry for Adults and Children

Patient	Intravenously administered activity, MBq/kg (mCi/kg)	Organ receiving the largest radiation dose, mGy/MBq (rads/mCi)	Effective dose, mSv/MBq (rems/mCi)
Adult	370–740 (10–20)	Bladder, 0.16^* (0.59)	0.019 (0.070)
Child (5 y old)	5.18–7.4 (0.14–0.20)	Bladder, 0.32^† (1.2)	0.050 (0.18)

↵* Voiding interval, 3.5 h. Changes in bladder wall dose are approximately linear with changes in voiding interval; therefore, for a voiding interval of 2.0 h, dose to bladder wall would change by a factor of 2/3.5.
↵† Voiding interval, 2.0 h.

TABLE 2

Summary of PET/CT On-The-Job Training Requirements

Training	Board certification	No. of PET/CT interpretations (supervised)^*	No. of CT interpretations (supervised)^†	PET/CT CME credits	CT CME credits
Nuclear medicine	ABNM	150	500	8	100
Diagnostic radiology (recent CT)^‡	ABR	150		35
Nuclear radiology (recent CT)^‡	ABR	150		8
Radiology (recent CT)^‡	ABR and ABNM	150		8
Diagnostic radiology (no recent CT)	ABR	150	500	35	100

↵* Supervision should be performed by qualified nuclear medicine physicians or diagnostic radiologists who have interpreted more than 500 PET/CT studies.
↵† Supervision should be performed by qualified diagnostic radiologists as defined in American College of Radiology Practice Guidelines for Performing and Interpreting Diagnostic Computed Tomography. CT cases should include reasonable distribution of head and neck, chest, abdomen, and pelvis.
↵‡ Includes radiologists or nuclear radiologists with recent experience in body CT (100 body CT cases/y for preceding 5 y).
ABNM = American Board of Nuclear Medicine.
