Background
A small remnant liver volume is an important risk factor for posthepatectomy liver failure. ImageJ and OsiriX
®
are both free, open-source image processing software packages. The aim of the present study was to compare ImageJ and OsiriX
®
in performing prospective computed tomography (CT) volumetric analysis of the liver on a personal computer (PC) in patients undergoing major liver resection.
Methods
Patients scheduled for a right hemihepatectomy were eligible for inclusion. Two surgeons and one surgical trainee measured volumes of total liver, tumor, and future resection specimen prospectively with ImageJ and OsiriX
®
. A radiologist also measured these volumes with CT scanner-linked Aquarius iNtuition
®
software. Resection volumes were compared with the actual weights of the liver specimens removed during surgery, and differences between the measured liver volumes were analyzed.
Results
A total of 15 patients (8 men, 7 women) with a median age of 63 years (48–79 years) were included. There was a significant correlation between the measured weights of resection specimens and the volumes calculated prospectively with ImageJ and OsiriX
®
(
r
 = 0.89;
r
 = 0.83, respectively). There was also a significant correlation between the volumes measured with radiological software iNtuition
®
and the volumes measured with ImageJ and OsiriX
®
(
r
 = 0.93;
r
 = 0.95, respectively).
Conclusions
There were no major differences in total liver volumes, resection volumes, or tumour volumes for these three software packages. Prospective hepatic CT volumetry with ImageJ or OsiriX
®
is reliable and can be accurately used on a PC by nonradiologists. ImageJ and OsiriX
®
yield results comparable to the radiological software iNtuition
