Credentialing in radiology: Current practice and future challenges

Table 2 A complete case example of credentialing in radiology, from the Royal Australian and New Zealand College of Radiologists computed tomography colonography accreditation programme guidelines[27]

Modality/country and Institute	Credentialing requirements
CTC	Minimum of 60 CTC cases required by practitioner for independent performance:
RANZCR, through the Abdominal Radiology Group of Australia and New Zealand, 2013[27]	Cases should be worked up from raw data on a workstation by applicant 50 cases must be validated by surgery or endoscopy
	10 cases should be "live" where: Practitioner must be personally present for duration of examination

	Practitioner must be named on examination report as the co-reporting CTC trainee
	Form of evidence: RIS record ± logbook
	Case training can be acquired through the following:
	Hands-on workshops
	Abdominal imaging fellowships
	On-site training via the supervision of a CTC specialist
	Mentored electronic library cases
	On-going competency: To maintain CTC competency a minimum of 30 examinations per year must be interpreted
	All cases worked up by applicant from raw data on a workstation
	All cases must be recorded in RANZCR CTC logbook
	In their annual RANZCR CPD returns CTC specialists must declare whether they have completed their on-going requirements. Their declaration will be subject to random audit and CTC specialists may be asked to provide evidence to substantiate their logbook recordings
	Those who do not maintain competency requirements will be suspended from the register, until a logbook of 30 cases is submitted[27]
