Area of Science:

  • Neurosurgery
  • Radiology
  • Oncology

Background:

  • Accurate measurement of vestibular schwannoma (VS) size is crucial for monitoring tumor growth and treatment efficacy.
  • Existing radiographic techniques for VS size assessment include maximum linear dimension (MLD), orthogonal volumetric analysis (OVA), and segmented volumetric analysis (SVA).
  • The precision and reproducibility of these methods can vary, impacting clinical decision-making.

Purpose of the Study:

  • To compare the precision and reproducibility of three radiographic measurement techniques for assessing vestibular schwannoma (VS) tumor size.
  • To evaluate interobserver agreement and the smallest detectable difference for each measurement technique.

Main Methods:

  • Twenty patients with unilateral, sporadic, untreated vestibular schwannomas were included.
  • Thin-slice T1-weighted, post-contrasted magnetization-prepared rapid acquisition gradient echo images were analyzed.
  • Three measurement techniques (MLD, OVA, SVA) were performed, with interobserver agreement and repeatability coefficients calculated.

Main Results:

  • Segmented volumetric analysis (SVA) demonstrated the highest interobserver correlation coefficient.
  • SVA exhibited the lowest repeatability coefficient (174.8 mm³) and a smaller smallest detectable difference (30.6%) compared to MLD and OVA.
  • Subgroup analysis revealed SVA's increased precision for larger tumors (>14 mm).

Conclusions:

  • Semi-automated segmented volumetric analysis (SVA) is more precise for reporting vestibular schwannoma (VS) tumor size than MLD or OVA.
  • SVA becomes increasingly precise for larger tumors.
  • Tumor volume and change over time using SVA may offer more sensitive surveillance of VS compared to current methods.
