Key radiological magnetic resonance imaging (MRI) and computed tomography (CT) findings. F1 indicates a round vertebral signal intensity change (metastasis of prostate cancer); F2 indicates a band-like vertebral signal intensity change (osteoporotic vertebral fracture [OVF]); F3 indicates a diffuse vertebral signal intensity change (metastasis of lung cancer); F4 indicates a superior sharp protrusion of the posterior wall border (OVF); F5 indicates a smoothly blunt protrusion of the posterior wall border (metastasis of bladder cancer); F6 indicates an anterior vertebral convexity (metastasis of bladder cancer); F7 indicates a paravertebral solid mass (lymphoma); F8 indicates a sclerotic band beneath the end plate (OVF); F9 indicates a cleft fluid sign (OVF); F10 indicates an asymmetry in signal intensity (metastasis of kidney cancer); F11 indicates a pedicle involvement (metastasis of kidney cancer); F12 indicates a single-peaked posterior wall protrusion (OVF); F13 indicates a double-peaked posterior wall protrusion (metastasis of prostate cancer); F14 indicates a vertebral fracture without osteolysis (OVF); F15 indicates an osteolytic destruction (metastasis of lung cancer)
