To report the magnetic resonance imaging (MR) findings of acute cervical central cord syndrome and to determine their correlation with the prognosis.
MRI findings of 35 patients with acute central cord syndrome were studied and compared with the recovery rate of ASIA score at presentation and in follow-up.
MRI data demonstrated spinal cord compression for 32 patients, spinal cord swelling for 16 patients, and abnormal signal intensity within the spinal cord for 19 patients, including 14 with edema and 3 with hematoma. No significant difference of the recovery rate was noted between the patients treated nonoperatively and operatively (P > 0.05). There was a significant inverse correlation between the recovery rate and the degree of spinal cord compression as shown in MRI scans (P < 0.01). The presence of hematoma in MRI scans was associated with poor prognosis, as demonstrated by a significant difference of the recovery rate (P < 0.01) among the patients with normal intensity, edema and hematoma within the spinal cord.
MRI scans provide an efficient assistance for decision-making and accurate prognostic information regarding neurological function, and therefore should routinely be performed within the early phase of acute central cord syndrome.
报告急性颈髓中央综合征的磁共振成像（MR）表现，并确定其与预后的相关性。
研究35例急性中央脊髓综合征患者的MRI表现，并与就诊时及随访时的ASIA评分恢复率进行比较。
MRI数据显示32例患者存在脊髓受压，16例患者脊髓肿胀，19例患者脊髓内信号强度异常，其中14例为水肿，3例为血肿。非手术治疗和手术治疗患者的恢复率无显著差异（P>0.05）。MRI扫描显示恢复率与脊髓受压程度呈显著负相关（P<0.01）。MRI扫描中血肿的存在与预后不良相关，脊髓内强度正常、水肿和血肿患者的恢复率存在显著差异（P<0.01）。
MRI扫描为急性中央脊髓综合征早期的决策制定和神经功能的准确预后信息提供了有效的辅助，因此应常规进行。
