I. Human Resources
II. Steering Committee Role
III. Software to Track, Archive, Report and Analyse Dosimetric Data
- Detailed acquisition parameters and dose report for each patient study.
- Database export in Microsoft Excel format for further handling.
- Automated monthly reports that are sent via email.
- Automated alerts for high-level dose studies that assist in the fostering of dose awareness of the CT operators. The system provides a justification process for the alerts that allows the users to assess the centring of the patient, the function of the current modulation and the recording of the cause that produced the alert.
IV. Country/Site initiation process
- Each National Health System’s rules and country legislation. For instance, the variations between countries in the reimbursement system that affects the frequency of examinations; the referral criteria that affect the imaging modality choice.
- Differing perceptions of radiologists, referring physicians and patients of CT dose, between countries.
- Differences in workload, study types and patient’s condition between private diagnostic centres and public and/or private hospitals.
- Differences in mentality between the generations of radiologists and radiographers.
- Records and analyses the percentage of alerted high-level dose studies and the percentage of justified alerts;
- Records and analyses the percentages of examinations performed according to the Standardised CT protocols list rules;
- Records and analyses the percentage of protocols performed that are above, within or below the DRLs.
- The amount of ionising radiation exposure from CT is increasing, and there is great variability between patients and geographies for similar examinations.
- A rational strategy is required to both reduce and standardise patient dose over the full range of examination types.
- Affidea, a pan-European medical imaging services provider, has implemented a Dose Excellence Campaign across 7 European countries, involving approximately 190 people.
