摘要
目的探讨64排螺旋CT和MRI检查用于直肠癌术前分期诊断中的临床价值。方法经术后病理证实的72例直肠癌患者,其中36例用64排螺旋CT检查;36例用1.5T MRI检查比较两组患者的直肠癌分期的灵敏度。结果 MRI组直肠癌术前T分期N分期诊断灵敏度优于CT组,差异有统计学意义(P<0.05)。结论在直肠癌术前分期诊断中64排螺旋CT和MRI均有理想效果,但二者相比,MRI灵敏度、特异度更高,同时检查费用也更高,在临床选择中,应该根据实际情况合理应用。
Objective To investigate the clinical value of 64-slice spiral CT and MRI in the preoperative staging diagnosis of rectal cancer.Methods Seventy-two patients with rectal cancer confirmed by pathology after menstruation were collected,of which 36 patients were examined by 64-slice spiral CT before operation as the CT group.The remaining 36 patients underwent preoperative 1.5 T MRI examination as the MRI group.The sensitivity of rectal cancer staging was calculated and compared between the two groups.Results The sensitivity of preoperative T-staging and N-staging diagnosis of rectal cancer in the MRI group were both significantly better than those in the CT group,with a statistically significant difference(P<0.05).Conclusion 64-slice spiral CT and MRI have ideal effects in the preoperative staging diagnosis of rectal cancer.The sensitivity and specificity of MRI are higher than the those of 64-slice spiral CT.However,the cost of MRI examination is higher than that of the 64-slice spiral CT.So,they should be reasonably applied in the clinical selection according to the actual situation.
