Methods to Improve Fiber Reconstruction at DTI-Based Tractography in the Area of Brain Tumor: Case Illustration and Literature Review

Background and Aim: Diffusion Tensor Imaging (DTI)-based tractography can help us visualize the spatial relation of fiber tracts to brain lesions. Several factors may interfere with procedure diffusion-based tractography, especially in tumors. The current study aims discuss several solutions improve reconstruction adjacent or inside Illustrative cases are also presented. Methods Materials/Patients: paper is a narrative review methods that DTI-based area To provide up-to-date information, we briefly reviewed related articles extracted from Google Scholar, Medline, PubMed. Results: We proposed five techniques reconstruction. Technique 1 very low Fractional Anisotropy (FA) application. 2 includes resampling techniques, such as q-ball High Angular Resolution (HARDI). 3 by defining separated Region Interest (ROIs). 4 explains selection ROIs according functional Magnetic Resonance (fMRI) since anatomical configuration distorted neoplasm. 5 consists using unprocessed images for preoperative planning correlation clinical situation. Conclusion: DTI highly sensitive noise artifacts. application imaging tumors edema.
