A diabetic patient presents for oncology FDG PET with a capillary glucose of 305 mg/dL. Which action is most appropriate?

WHYHyperglycaemia competes with FDG at the GLUT transporter and lowers lesion conspicuity. Insulin is the trap: it drives FDG into skeletal muscle and myocardium, degrading the study further. Extending uptake or raising activity does not overcome the competitive block.

Who can sit it

One route requires an active NMTCB CNMT, ARRT(N) or CAMRT(RTNM) certification together with a minimum of 700 hours of clinical experience on a dedicated PET scanner. Separate routes exist for certain ARRT and CAMRT certificants, with additional coursework and competency requirements.

The PET credential is time limited and expires after seven years, which is worth planning for rather than discovering later.

How this question bank maps to the exam

The 200 questions are distributed to match the published outline: 70 diagnostic procedures, 60 instrumentation and quality control, 50 radiopharmaceuticals and 20 radiation protection. That is the same 35/30/25/10 split the board uses, so practice time lands where the marks are.

Two hundred is also the number of scored items on the real exam, so the bank is a full exam's worth of practice rather than an arbitrary round number.
