A comparison of semi-automated volumetric vs linear measurement of small vestibular schwannomas

Objective Accurate and precise measurement of vestibular schwannoma (VS) size is key to clinical management decisions. Linear measurements are used in routine clinical practice but are prone to measurement error. This study aims to compare a semi-automated volume segmentation tool against standard l...

Description
Summary:Objective Accurate and precise measurement of vestibular schwannoma (VS) size is key to clinical management decisions. Linear measurements are used in routine clinical practice but are prone to measurement error. This study aims to compare a semi-automated volume segmentation tool against standard linear method for measuring small VS. This study also examines whether oblique tumour orientation can contribute to linear measurement error. Study design Experimental comparison of observer agreement using two measurement techniques. Setting Tertiary skull base unit. Participants Twenty-four patients with unilateral sporadic small (
