Abstract

Purpose: To develop and integrate interactive features with automatic methods for accurate liver cyst segmentation in patients with autosomal dominant polycystic kidney and liver disease (ADPKD).

Methods: SmartClick and antiSmartClick were developed using iterative region growth guided by spatial and intensity connections and were integrated with automated level set (LS) segmentation and graphical user interface, forming an intelligent rapid interactive segmentation (IRIS) tool. IRIS and LS segmentations of liver cysts on T2 weighted images of patients with ADPKD (n = 17) were compared with manual segmentation as ground truth (GT).

Results: Compared to manual GT, IRIS reduced the segmentation time by more than 10-fold. Compared to automated LS, IRIS reduced the mean liver cyst volume error from 42.22% to 13.44% (p < 0.001). IRIS segmentation agreed well with manual GT (79% dice score and 99% intraclass correlation coefficient).

Conclusion: IRIS is feasible for fast, accurate liver cyst segmentation in patients with ADPKD.

Keywords: intelligent rapid interactive segmentation; lesion segmentation; liver cyst.

Liver cyst segmentation by (a) manual as ground truth (GT), (b) automated level set (LS), and (c) IRIS. LS included substantial vasculature (b), which was cleaned up rapidly using antiSmartClick (c). Small cysts missed on manual GT were captured on IRIS (arrows in (c)).

Scatter plots of liver cyst volume measurements by (a) LS and (b) IRIS against GT. IRIS improved regression slope and regression coefficient. GT = ground truth segmentation, LS = automatic level set segmentation, and IRIS = intelligent rapid interactive segmentation.

Bland–Altman plots for (a) LS and (b) IRIS for cyst volume measurements. LS had a bias of 8.53%, STD of 61.61%, lower limit of agreement (LLA) of −112%, and upper limit of agreement (ULA) of 129%. (a). IRIS had a bias of −5.49%, STD of 15.94%, LLA of −37%, and ULA of 26%. GT = ground truth segmentation, LS = automatic level set segmentation, IRIS = intelligent rapid interactive segmentation, and STD = standard deviation.

Liver cyst segmentation by manual GT (a), automated LS (b), and IRIS (c). The voxels in the space between neighboring cysts (arrows in (c)) were easily included in the manual GT, contributing to the observed segmentation errors. GT = ground truth segmentation, LS = automatic level set segmentation, and IRIS = intelligent rapid interactive segmentation.
