The Central Vein Sign as a Radiologic Tool to Predict the Diagnosis of Radiation Necrosis in Intracranial Metastatic Cancer Patients
Radiosurgery (SRS) is a primary treatment for intracranial metastatic disease, but it can lead to cerebral radiation necrosis (RN) in approximately 25% of cases. Unlike tumor progression (TP), which indicates a lack of response to treatment, RN suggests an effective SRS response. Differentiating RN...

| Summary: | Radiosurgery (SRS) is a primary treatment for intracranial metastatic disease, but it can lead to cerebral radiation necrosis (RN) in approximately 25% of cases. Unlike tumor progression (TP), which indicates a lack of response to treatment, RN suggests an effective SRS response. Differentiating RN from TP is challenging using standard radiological imaging, often necessitating surgical biopsy. This study investigates the utility of the central vein sign (CVS), a novel MRI biomarker associated with immune infiltrate-rich perivascular spaces, to differentiate RN from TP. Overall, our findings suggest that pre-SRS CVS could serve as a non-invasive marker to distinguish RN from TP, aiding in treatment decisions. Further research is needed to validate CVS as a predictive marker in larger patient cohorts and explore its potential in guiding cancer therapy response. |
