LETT-NeXt: A Lightweight RECIST-Guided Model for 3D CT Lesion Segmentation
Sebastian Aas, Elias Stenhede, Arian Ranjbar
RECIST diameter measurements are widely used for tumor response assessment, but they provide only a limited 2D description of lesion extent. We present LETT-NeXt, a lightweight RECIST-guided model that predicts 3D lesion masks from CT volumes and RECIST markers for the CVPR 2026…
