Researchers have developed a novel patient-specific conditional implicit neural representation (INR) designed to handle missing sequences and varying resolutions in longitudinal multiparametric MRI data. This model treats MRI data as a continuous function of coordinates, time, and modality, enabling spatial and temporal interpolation without fixed voxel grids. Evaluated on pediatric brain tumor patient data, the INR demonstrated statistically significant improvements over linear interpolation for T1CE and FLAIR sequences, achieving a mean MS-SSIM of 0.95 for T1CE.
