| Frontiers in Physiology
Abstract Background: Spinal tuberculosis is the most common extrapulmonary manifestation of tuberculosis. Magnetic resonance imaging (MRI), particularly fat-suppressed T2-weighted imaging (FS-T2WI), is the modality of choice for preoperative evaluation; yet indistinct lesion boundaries render manual delineation subjective and poorly reproducible. Although deep learning segmentation has advanced considerably, its “black-box” nature and limited interpretability remain critical obstacles.

| Frontiers
Abstract Objectives: To evaluate the diagnostic value of quantitative 99mTc-MDP SPECT/CT metabolic, CT attenuation, and adjacent vertebra integrated parameters for differentiating spinal tuberculosis (STB) from spinal metastases (SM). Materials and methods: This retrospective study included 212 patients who underwent quantitative 99mTc-MDP SPECT/CT, including 94 with STB and 118 with SM.
