Implication

Retrospective study establishes national reference levels for SPECT imaging in adults, indicating lower radiation doses than regional standards.

Key Points

  • Establish national diagnostic reference levels (DRLs) for routine adult single-photon emission computed tomography (SPECT) examinations in Bahrain to optimize radiation dosing.
  • Conducted a retrospective multicenter analysis collecting administered radiopharmaceutical activities (MBq) from two major nuclear medicine centers representing most national services in Bahrain.
  • Included 1,098 studies from adult patients weighing 70 kg ± 20% undergoing standard SPECT procedures.
  • Calculated proposed DRLs using the 75th percentile of administered activity in accordance with ICRP Publication 135 guidelines.
  • Variations in administered activity were observed between the two participating nuclear medicine centers.
  • Proposed national DRLs were lower than previously reported regional values from Kuwait and Saudi Arabia and were within range of European benchmarks.
