Synedra, a free digital imaging viewer, is relevant in assessment of frontal sinus drainage pathway

Abstract

Objective The aim was to evaluate the most relevant free radiological digital imaging and communications in medicine (DICOM) software in analysis of air cells related to the frontal sinus drainage pathway (FSDP). Background DICOM is the leading standard for computed tomography (CT) scan image data management in different paranasal sinuses and rhinology practice. Patients and methods In the present prospective randomized case-series study of 51 patients scheduled for CT scan for nose and paranasal sinuses, six DICOM image viewers (Onis, Synerdra, 3D-Slicer, InVesalius, RadiAnt, and Philips) were compared by two expert head and neck radiologists for analysis of CT FSDP anatomy using modified Bent–Kuhn classification, which presents a total score for 10 commonly used radiological parameters. Each was scored from 0 to 10, and a total score and mean were calculated. Results Synedra software had the highest total mean scores (64.5/100) followed by RadiAnt (45/100), 3D-slicer (29.5/100), Onis (16/100), and Invesalius (15/100), with the least being Philips (14.5/100). Conclusion Synedra could be a relevant free DICOM viewer for analysis of air cells related to the FSDP.
