目的研究MRI与CT诊断胫骨平台 骨折的临床效果。方法 选取我院105例胫 骨平台骨折患者为研究对象，受检者均行 MRI、CT检查，将检查结果与手术病理诊 断结果进行比较，以分析胫骨平台骨折患 者MRI与CT检查特点。结果 两种检测方 式对骨折粉碎、骨折移位、骨缺损、骨 折部位显示效果比较无统计学意义(P＞ 0.05)；手术病理证实B1型27例、B2型20 例、B3型11例、C1型28例、C2型11例、 C3型8例，CT诊断符合率分别为88.89%、 95.00%、100.00%、82.14%、90.91%、 87.50%，与MRI 100.00%、100.00%、 100.00%、92.86%、100.00%、100.00%比 较无统计学意义(P＞0.05)，但MRI部分 骨型诊断符合率偏高；CT诊断骨折及分 型准确率分别为93.33%、90.48%与MRI诊 断98.10%、97.14%比较较低，其中分型 符合率比较有统计学意义(P＜0.05)。结 论 MRI与CT均为胫骨平台骨折诊断有效方 式，两者比较以MRI价值偏高。

Objective To study the clinical effect of MRI and CT in diagnosis of tibial plateau fractures. Methods 105 cases of patients with tibial plateau fractures in the hospital were selected as the research object. All of the subjects received MRI and CT examination. The examination results were compared with the results of surgical and pathological diagnosis to analyze the features of MRI and CT for patients with tibial plateau fractures. Results The differences in the display results of the two kinds of detection methods for comminuted fracture, displacement fracture, bone defect, fracture sites were not statistically significant (P>0.05); surgical pathology confirmed that there were 27 cases of type B1, 20 cases of type B2, 11 cases of type B3, 28 cases of type C1, 11 cases of type C2 and 8 cases of type C3. The diagnose accordance rates of CT diagnosis respectively were 88.89%, 95%, 100.00%, 82.14%, 90.91% and 87.50%. There was no significant difference, compared with 100.00%, 100.00%, 100.00%, 92.86%, 100.00% and 100.00% (P>0.05)but the diagnose accordance rates of MRI diagnosis for parts of the bone types was too high; the accuracy of CT in diagnosis of fracture and classification of types were 93.33% and 90.48% which were relatively lower than 98.10% and 97.14% of MRI diagnosis. The coincidence rate of classification of types was statistically significant (P<0.05). Conclusion MRI and CT were effective ways for diagnosis of tibial plateau fractures, while between the two, the value of MRI was higher.
