Challenge of prostate MRI segmentation on T2-weighted images: inter-observer variability and impact of prostate morphology

Montagne, Sarah Hamzaoui, Dimitri Allera, Alexandre

Background:Accurate prostate zonal segmentation on magnetic resonance images (MRI) is a critical prerequisite for automated prostate cancer detection. We aimed to assess the variability of manual prostate zonal segmentation by radiologists on T2‑weighted (T2W ) images, and to study factors that may influence it.Methods:Seven radiologists of...

Prostate volume prediction on MRI: tools, accuracy and variability

Hamzaoui, Dimitri Montagne, Sarah Granger, Benjamin

OBJECTIVE: A reliable estimation of prostate volume (PV) is essential to prostate cancer management. Theobjective of our multi-rater study was to compare intra and inter-rater variability of PV frommanual planimetry and ellipsoid formulas.METHODS: Forty treatment-naive patients who underwent prostate MRI were selected from a localdatabase. PV...

Reference standard for the evaluation of automatic segmentation algorithms: Quantification of inter observer variability of manual delineation of prostate contour on MRI

Molière, Sébastien Hamzaoui, Dimitri Luzurier, Anna

The purpose of this study was to investigate the relationship between inter-reader variability in manual prostate contour segmentation on magnetic resonance imaging (MRI) examinations and determine the optimal number of readers required to establish a reliable reference standard. Materials and methods: Seven radiologists with various...
