KEY FACTS

  • Terminology

    TERMINOLOGY

    • Description

      • Percentage of final reports for patients aged 18+ years undergoing CT with documentation that 1+ of following dose-reduction techniques were used
        • Automated exposure control
        • Adjustment of mA &/or kV according to patient size
        • Use of iterative reconstruction technique
    • Rationale

      • There are estimates that CT scans account for 17% of total imaging procedures performed in United States each year and 49% of collective radiation dose from imaging procedures. Current advances in technology have resulted in several methods to reduce radiation dose for patients undergoing CT. Studies show that CT dose-optimization techniques can reduce radiation dose by 40-50% without sacrificing image quality or diagnostic ability.
    • Instructions

      • This measure is to be submitted each time patient has CT scan during performance period. There is no diagnosis associated with this measure. It is anticipated that Merit-Based Incentive Payment System (MIPS)-eligible clinicians who provide professional component of diagnostic imaging studies for CT will submit this measure.
    • Numerator

      • Final reports with documentation that indicate individualized dose-optimization technique was used for performed procedure. Dose-optimization techniques include following
        • Automated exposure control
        • Adjustment of mA &/or kV according to patient size
        • Use of iterative reconstruction technique
    • Denominator

      • All final reports for patients aged 18+ years undergoing CT
