IMIV unit (SHFJ), in collaboration with the Gustave Roussy Institute, has developed the free software platform LIFEx that allows to characterize the tumor heterogeneity from any type of medical images: PET, MRI, scanner, ultrasound. With nearly 900 members, this platform has an international success because it facilitates the realization of radiomic studies, conducted in the context of personalized medicine.
Textural and shape analysis is gaining considerable interest in medical imaging, particularly to identify parameters characterizing tumor heterogeneity and to feed radiomic models. Here we present a free, multiplatform, and easy-to-use freeware called LIFEx, which enables the calculation of conventional, histogram-based textural and shape features from PET, SPECT, MR, CT, and US images, or from any combination of imaging modalities. The application does not require any programming skills and was developed for medical imaging professionals. The goal is that independent and multicenter evidence of the usefulness and limitations of radiomic features for characterization of tumor heterogeneity and subsequent patient management can be gathered. Many options are offered for interactive textural index calculation and for increasing the reproducibility among centers. The software already benefits from a large user community (more than 800 registered users), and interactions within that community are part of the development strategy.Read the French version.
