Volumetric assessment of MRI images is associated to an intrinsic risk of miscalculation. OsiriX showed the shortest analysis time. For the actual tumors, the estimated volumes with all three software tools showed a low coefficient of variability, but the mean volume estimates differed among the tools. The mean volume estimated by all three software programs differed significantly from the true volume of the phantoms, but OsiriX and BrainLab gave estimates that were not significantly different from each other. The software was compared with regard to accuracy and reproducibility of the measurements and time required for analysis. We performed volumetric measurements on phantoms with predefined volumes (0.1 to 8.0 ml) and tumors seen on 32 head MRI scans from eight NF2 patients with BrainLab, ITK-Snap, or OsiriX. We present a statistical and methodical comparison of three volumetric image analysis tools. Volumetric tumor measurements are essential to assess the efficacy of new therapies. Hallmarks are bilateral benign vestibular schwannomas, which can lead to deafness or brainstem compression. Perhaps I will chg it to a 5 afterwards.Neurofibromatosis type 2 is a neurogenetic disorder with an incidence of about 1:33.000. However, rest assured I will be putting it to the test as I have a plethora (can you say “plethora”?) of discs w X-rays, CT’s. However, I no longer have to worry about buying OsiriX, which I wouldn’t do anyways bc when you’re living on an extremely limited fixed income, such niceties become even more extremely difficult to justify even a penny to it,Īnyways it does for the most part what it says it does & I’m sure most of the quirks I encountered were due to my lack of experience w the app. I’m giving it 4 stars bc it’s still got some quirks. I decided to look in the app store & voila, this beautiful little app which not only worked great (so far) but it’s entirely free to boot! Recently I had more X-rays & decided to try looking at them after the VA gave me a disc. They had one you could buy but my experience w the free one was so poor that there was no way I was going to buy it.

Then I was living in the woods for 4 yrs (long story, another adventure) & when I finally got to a place where I could use my old G4 the app was bad. Years ago (like 10 maybe? I’m blessed w ADHD so I have absolutely no concept of time) I had downloaded that OsiriX when it was free & was viewing all my MRI’s, etc.
