Results (1) Osteitis and destruction of end-plate showed long T1 and long T2.(2) Anterior and lateral abscess had long T1 and long T2 presenting even and structure-less signal.(3) The intervertebral discs showed normal or only degeneration at the early stage, and destroyed at later stage.(4) With Gd-DTPA enhancement, fibrotic granulation around abscess and destroyed area was well demonstrated.(5) Abscess in the bone and/or paraspinal abscess, destruction of end-plate were the important evidence for early diagnosis.

结果 (1)椎体骨炎及终板破坏呈长T1长T2信号，(2)椎旁或椎前冷脓肿呈长T1长T2均匀无结构信号，且上下跨越范围较大，(3)早期椎间盘信号正常或只出现退变，晚期则被破坏，(4)Gd-DTPA增强扫描可清楚显示冷脓肿周围纤维肉芽组织及椎管内侵犯，(5)骨内小脓肿和/或椎旁脓肿、椎体终板破坏是MRI诊断早期脊柱结核的重要依据。
