CTE Sessions at EANM’11

EANM’11 – CTE Session I

October 16, 2011, 08:15 – 09:45
Team Working in Clinical Dosimetry Daily Practice

Moderators: G. Testanera (Milan), M. Bardies (Nantes)

C. Canzi (Milan):
Probes and Well Counter in Clinical Dosimetry: Common Practice and Clinical Applications
C. Chiesa (Milan):
Gamma Camera in Clinical Dosimetry: Common Practice and Clinical Applications
K. Bacher (Gent):
Dose Absorption and Protocol Optimization in PET/CT Clinical Practice

Educational objectives:

Upon completion of this session the attendee will have an understanding of:

  1. Introduction to clinical dosimetry
  2. Instrumentation description and calibration
  3. Protocol optimization
  4. Clinical practice application
  5. CT and PET phantom studies
  6. Dose absorption calculation
  7. Administered activity optimization
  8. Radiation protection application
  9. Working team and role of Technologists


Quantitative analysis based on data collected by means of Nuclear Medicine (NM) instrumentation may involve strict cooperation of different professionals operating in NM departments, including physicists and technologists.

Part of the session will deal with how to perform clinical dosimetry calculation with probes, well counter and gamma cameras. It will also consider which clinical applications these procedures may have (pre-therapeutic risk organ dosimetry, post-therapeutic dosimetry, dose optimization) and how technologists can be involved in it.

The third talk will focus on how to calculate dose absorption for a PET-CT examination with FDG or other radiopharmaceuticals (phantom studies). The talk will also analyze how we can optimize protocols and personalize activity administration for lowering patient dose without losing exam diagnostic value.

Key Words:

Clinical Dosimetry, Gamma Camera, PET/CT, Well Counter, Protocol Optimization, Patient Radiation Protection, Team Work
