A 2-year period of training in the complementary specialty subsequent to the base specialisation in either radiology or nuclear medicine is recommended. The practical incorporation and training of this will vary from country to country, but it is recommended that a period of circa 18 months be dedicated to cross-sectional imaging techniques of the complementary specialty, i.e., to PET and SPECT for radiologists, and CT and MRI for nuclear physicians.
This would allow a 6-month period to be used in acquiring additional knowledge of the core principles of the complementary specialty. It is recommended that national authorities allow 12 months of training in the complementary specialty to be recognised as part of the training in the base specialty for accreditation purposes. This time structure would allow completion of full specialisation plus competency in multimodality imaging within a period of 6 years. A common trunk approach to training is not supported by this curriculum.
