Hepatectomies are performed increasingly more often, mainly because indications for liver resection are continuously being extended. ImageJ and OsiriX ® yield results comparable to the radiological software iNtuition ®.

Prospective hepatic CT volumetry with ImageJ or OsiriX ® is reliable and can be accurately used on a PC by nonradiologists. There were no major differences in total liver volumes, resection volumes, or tumour volumes for these three software packages. 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). 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). ResultsĪ total of 15 patients (8 men, 7 women) with a median age of 63 years (48–79 years) were included. Resection volumes were compared with the actual weights of the liver specimens removed during surgery, and differences between the measured liver volumes were analyzed. A radiologist also measured these volumes with CT scanner-linked Aquarius iNtuition ® software.

Two surgeons and one surgical trainee measured volumes of total liver, tumor, and future resection specimen prospectively with ImageJ and OsiriX ®. Patients scheduled for a right hemihepatectomy were eligible for inclusion. 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. ImageJ and OsiriX ® are both free, open-source image processing software packages.

A small remnant liver volume is an important risk factor for posthepatectomy liver failure.
