Area of Science:

  • Medical Imaging
  • Vascular Surgery

Background:

  • Sequential volumetric analysis of abdominal aortic aneurysms (AAA) aids in endoleak exclusion post-aortic endostent placement.
  • Operator experience is a potential variable affecting the accuracy of volumetric calculations.

Purpose of the Study:

  • To compare the effect of varying operator experience levels on the accuracy of abdominal aneurysm volume calculations.
  • To establish a margin of error for AAA volume measurements based on operator expertise.

Main Methods:

  • Four operators with distinct experience levels (high, moderate, low) performed volumetric calculations on 10 AAA patient scans at two separate time points.
  • Volume calculations were performed using a GE Advantage 4.0 workstation.
  • Operators were categorized by their experience in 3D/CT analysis.

Main Results:

  • Statistically significant differences (p < 0.005) were observed in volume measurement accuracy based on operator experience.
  • Average percent volume differences were 1.2% (experienced), 3.2% (moderately experienced), and 5.8-6.0% (low experience).

Conclusions:

  • A direct correlation exists between operator experience level and the percent margin of error in AAA volume measurement.
  • Accurate diagnosis of endoleak, relying on aneurysm volume changes in serial scans, must consider the operator's experience level.
