目的分析讨论彩色多普勒超声诊断视网膜母细胞瘤与核磁共振(MRI)的临床效果比较。方法 31例视网膜母细胞瘤患儿,均接受彩色超声多普勒检查与核磁共振检查,并以病理检查结果作为准断的参考标准,比较两种检查手段的准确性。结果 31例患儿中34只眼睛接受检查,彩色超声多普勒检查的准确率为94.12%、误诊率为5.88%;核磁共振检查的准确率为67.65%、误诊率为32.35%;17例患儿肿瘤发生不同程度的钙化,彩色超声多普勒与核磁共振的检出率分别为88.24%、58.82%,比较差异具有统计学意义(P<0.05)。两种检查方法灵敏度比较差异有统计学意义(P<0.05)。结论对于视网膜母细胞瘤的筛查,临床可应用彩色多普勒超声进行,具有较高的检出率,可以准确对肿瘤位置、钙化程度做出判断,且费用较低,更容易被患儿接受,值得推广。
Objective To analyze and compare the clinical effects of color Doppler ultrasound in diagnosing retinoblastoma and magnetic resonance imaging (MRI). Methods Thirty-one children with retinoblastoma underwent color Doppler sonography and magnetic resonance imaging. The pathological findings were used as the reference standard to determine the accuracy of the two methods. Results 34 eyes of 31 children were examined. The accuracy of color Doppler ultrasound examination was 94.12%, the rate of misdiagnosis was 5.88%. The accuracy rate of MRI was 67.65% and the rate of misdiagnosis was 32.35%. Seventeen patients Children with different degrees of calcium calcification, color Doppler ultrasound and nuclear magnetic resonance detection rates were 88.24%, 58.82%, the difference was statistically significant (P <0.05). The sensitivity of the two methods were significantly different (P <0.05). Conclusion For the screening of retinoblastoma, the clinical application of color Doppler ultrasound, with a high detection rate, can accurately determine the location of the tumor, the degree of calcification, and the cost is lower, more easily in children Accepted, it is worth promoting.
