Observer error in computed tomography pelvimetry is significant, particularly for anteroposterior outlet measurements. This variability raises doubts about the clinical utility of these pelvic measurements.

Area of Science:

  • Radiology
  • Obstetrics
  • Pelvic Anatomy

Background:

  • Computed tomography pelvimetry is utilized in clinical settings for assessing pelvic dimensions.
  • Quantifying observer error is crucial for determining the reliability of these measurements.

Purpose of the Study:

  • To quantify observer error in computed tomography pelvimetry measurements.
  • To assess the confidence level in classifying pelvic measurements as adequate or inadequate.

Main Methods:

  • Five observers measured anteroposterior inlet, anteroposterior outlet, transverse inlet, and interspinous distances from CT pelvimetry examinations at two institutions.
  • Intraobserver and interobserver variation were analyzed using analysis of variance.
  • Reliability was assessed using intraclass correlation coefficient, and combined error was calculated.

Main Results:

  • Standard errors of measurement for bony pelvic dimensions were: anteroposterior inlet, 2.0 mm; anteroposterior outlet, 6.9 mm; transverse inlet, 1.3 mm; interspinous distance, 2.1 mm.
  • The 95% confidence interval for a recommended anteroposterior outlet of 100 mm was 88.5-111.3 mm.
  • Significant observer variation was noted for anteroposterior outlet measurements.

Conclusions:

  • Observer variation in anteroposterior outlet measurement is substantial.
  • The large measurement error calls into question the clinical utility of anteroposterior outlet measurements in computed tomography pelvimetry.
