Detection of Osseous Spinal Metastasis with T1-Weighted Dynamic Contrast-Enhanced MRI and 18F-FDG PET/CT: Assessing Agreement in Biopsy Proven Cases.

Key Points

This research aims to compare dynamic contrast-enhanced MRI and FDG PET/CT in detecting osseous spinal metastases confirmed by biopsy.
Used T1-weighted dynamic contrast-enhanced MRI alongside FDG PET/CT scans.
Analyzed metrics such as Vp and SUVmax for agreement in detection of metastases.
Evaluated quantitative measures of tumor viability from both imaging techniques.
Vp showed higher levels than SUVmax in identifying viable tumors.
Both imaging methods provided essential complementary information for diagnosis.
Agreement noted between DCE-MRI and FDG PET/CT in biopsy-proven cases.

Abstract

Vp and SUVmax exhibit agreement in detecting osseous spinal metastases. However, when common thresholds for these metrics are applied, Vp exceeds SUVmax in identifying viable tumor. DCE-MRI plays a crucial role in detecting spinal metastases and offers complementary qualitative and quantitative information that can augment diagnosis and characterization of spinal metastases in addition to 18F-FDG PET/CT.
