摘要
目的探讨22 MHz超高频超声与13 MHz高频超声用于浅表性婴幼儿血管瘤病情评估的效果。方法分别应用22 MHz与13 MHz超声探头采集33例深度〈1 cm的浅表性婴幼儿血管瘤患者瘤体同一断面的二维及彩色血流图像,彩色血流图像选取探头正下方1 cm×1 cm,采用Image Magick软件分析。将二维图像按瘤体边界能否辨别进行分类,比较两者的瘤体边界辨别能力;将彩色血流图像自0.5 cm深度进一步细分为浅、深两部分,比较两者在相同深度的彩色血流显示能力。结果 22 MHz超高频超声对瘤体边界的辨别能力与13 MHz高频超声比较差异无统计学意义（χ^2=0.44,P=0.51）;22 MHz超高频超声与13 MHz高频超声对瘤体血流的显示能力在不同深度比较差异有统计学意义（0-0.5 cm：t=-9.38,P〈0.05;0.5-1.0 cm：t=4.59,P〈0.05）;但总的血流显示能力比较差异无统计学意义（t=-1.63,P=0.11）。结论 22 MHz超高频超声对瘤体深度〈0.5 cm的浅表性婴幼儿血管瘤的病情评估较13 MHz高频超声可提供更清晰的二维图像及血流信号更丰富的彩色图像。
Objective To compare the efficacy of 22 MHz ultra-high-frequency ultrasound and 13 MHz high-frequency ultrasound in assessing the clinical condition of superficial infantile hemangiomas. Methods We collected the two-dimensional ultrasound images and color Doppler flowimages of the same section of 33 patients whose tumor＇s depth was less than 1cm with 22 MHz and 13 MHz ultrasound separately,selected the 1 cm × 1 cm areas just under the probe from these color Doppler flowimages and analyzed them by software Image Magick. After that,we classified these two-dimensional ultrasound images according to whether the boundary of the tumors could be recognized and compared the results. We then separated every color Doppler flowimage into two parts from the depth of 0. 5cm to compare the two types of ultrasounds＇ ability to display the blood flow. Results 22 MHz ultra-high-frequency ultrasound was inferior to13 MHz high-frequency ultrasound in distinguishing the boundary of tumors（ χ^2= 0. 44,P = 0. 51）. There was no difference between the two types of ultrasounds in identifying the depth of tumors in color Doppler flowimages（ 0-0. 5 cm ： t =- 9. 38,P〈0. 05; 0. 5-1. 0 cm ： t = 4. 59,P〈0. 05）. There was no difference in displaying total bloodflow（ t =- 1. 63,P = 0. 11）. Conclusion Compared with 13 MHz high-frequency ultrasound,22 MHz ultra-high-frequency ultrasound can provide clearer two-dimensional ultrasound images and color Doppler flowimages with more blood flowabout a superficial infantile hemangioma when the depth of the tumor is less than 0. 5 cm.
