Radiographic characteristics of single and multiple osteoporotic vertebral compression fractures. The sagittal T2-weighted fat suppression MR imaging of single (a–c) and multiple (d–f) vertebral compression fractures. a A 78-year-old male complaining back pain for 5 days after fell on ground showed vertebral bone marrow edema in the cranial half of L1 vertebrae. The anterior and posterior height (red line) of fractured vertebrae was measured to quantify the degree of vertebral compression. b A 79-year-old female without spine trauma complained back pain for 1 week and showed diffused type of vertebral bone marrow edema in L1. c A 66-year-old female complained back pain for 4 days after heavy lift injury showed vertebral bone marrow edema in the caudal half of L3. d Two acute vertebral compression fractures in adjacent (T12 and L1) were detected in a 81-year-old male complaining back pain for 1 month without spine trauma. e Two acute vertebral compression fractures (L1 and L3) intermittent with one intact vertebrae (L2) were detected in a 74-year-old female complaining back pain for 1 month without spine trauma. f Four acute vertebral compression fractures (T8, T11, T12, and L1) with three in adjacent were detected in a 81-year-old female complaining back pain for 2 weeks without spine trauma
