Motivation: Brain metastases are common and difficult to diagnose accurately post-stereotactic radiosurgery (SRS), particularly in distinguishing true tumor progression (TP) from radiation necrosis (RN) non-invasively.
Goal(s): To develop a machine learning (ML) model using chemical exchange saturation transfer (CEST) imaging and MRI sequences to differentiate TP from RN.
Approach: Radiomic features from APT, NOE, and asymmetry CEST images, along with FLAIR, T1, and T2 MRI sequences, were extracted to train ML models for TP and RN classification.
Impact: These findings suggest that AI-driven analysis of combined CEST and MRI features could serve as an effective diagnostic tool in clinical practice, potentially improving patient management without the need for further invasive procedures.
