超高频超声与高频超声对浅表性婴幼儿血管瘤诊断价值比较

摘要

Objective To compare the clinical value of the superficial hemangioma in infants by ultra-high frequency ultrasonography and high frequency ultrasonography.Methods Forty-fire infants with superficial hemangioma were selected and tested by 13 MHz high frequency ultrasound probe and 20 MHz ultra-high frequency ultrasound probe,the clarity of the sonogram, different levels and different depth of blood flow proportion were compared.Results In 45 infants,hemangiomas were successfully imaged at both detection frequences(22 MHz and 13 MHz).The 22 MHz ultrasonic probe showed 36 cases with clear images and 9 cases with unclear images,the 13 MHz ultrasonic probe showed 32 cases with clear images and 13 cases with unclear images, the differences between two frequencies ultrasonography were statistically significant(P<0.05).There was no statistically significant difference between two frequencies of ultrasound image characteristics.The proportion of tumor blood flow detected by 13 MHz probe was(21.48±13.48)%,and the proportion of tumor blood flow detected by the 22 MHz probe was was(29.76± 16.84)%,the difference was statistically significant(P<0.05).At the two kinds of detection frequencies,the blood flow proportion of the trmor depth of 0~0.3 cm,0.4~0.6 cm,0.7~1.0 cm were all statistically significant(all P<0.05). Conclusion Ultra-high frequency of 20 MHz ultrasonic detection effect of superficial hemangiomas is superior to 13 MHz high frequency ultrasound detection,and the ability of blood flow imaging is also strong.Its role and the value in the clinical work is relatively high.%目的 比较超高频超声与高频超声诊断婴幼儿浅表性血管瘤的临床价值.方法 选取浅表性婴幼儿血管瘤确诊患儿45例,使用13 MHz高频超声与22 MHz超高频超声探头分别进行检测,比较其声像图清晰程度、不同层次及不同深度的血流比例等情况.结果 45例血管瘤患儿中,两种检测频率(22 MHz和13 MHz)下的血管瘤二维超声均成功显像,其中22 MHz探头显示图像清晰36例,模糊9例;13 MHz探头显示图像清晰32例,模糊13例,两种频率探头成像结果比较,差异有统计学意义(P<0.05).两种频率探头检出声像图特征构成差异无统计学意义.13 MHz探头检出瘤体血流比例为(21.48±13.48)%,22 MHz探头检出瘤体血流比例为(29.76±16.84)%,差异有统计学意义(P<0.05).两种检测频率下,瘤体深度为0~0.3 cm、0.4~0.6 cm、0.7~1.0 cm的血流比例比较,差异均有统计学意义(均P<0.05).结论 22 MHz超高频超声对浅表性血管瘤的检测效果优于13 MHz高频超声,且对于浅层瘤体检测能力更强,在临床工作中其作用及价值较大.
