How should we measure IPMN for an optimal follow-up?

IPMN is very common and most patients are only followed-up with an MRI. This study shows that simple manual evaluation in the axial plane is reliable and reproducible.

Key points:

  • MRI measurements by different radiologists can be used for IPMN follow-up.
  • Both diameter and volume measurements demonstrate excellent interobserver and intraobserver reproducibility.
  • Manual axial measurements show the highest interobserver reproducibility in determining size.
  • Axial and coronal volume measurements show similar limits of agreement.
  • Manual axial measurements show the lowest variability in agreement range.
