Shift in imaging modalities of the urinary tract over a 25-year period and its impact on ionizing radiation doses given to patients.

Objectives: To explore the shift in imaging modalities used when examining the urinary tract over the period 1979-2003 and to see how this shift, together with a radiation protection policy, have influenced the doses of ionizing radiation used.

Material And Methods: Activity reports from a department of radiology were reviewed. Relevant radiation dose estimates were obtained from the Norwegian Radiation Protection Authority.

Shift in imaging modalities of the spine through 25 years and its impact on patient ionizing radiation doses.

Study Design: Retrospective.

Objective: To explore the shift in modalities when diagnosing the spine in the years 1979-2003. To see how this shift, together with a radiation protective policy, have influenced on the ionizing radiation doses.
