Clinical Value of Color Doppler Ultrasound in Diagnosis of Children Intussusception

To analyze and evaluate the characteristics and effects of ultrasonography in the diagnosis of intussusception in children, the clinical data of 65 children with intussusception diagnosed by ultrasound were retrospectively analyzed. As a result, this group of children with intussusception confirmed by X-ray air enema reduction or surgery were diagnosed with no false-positive cases by color Doppler ultrasound. The characteristics of intussusception in children were as follows: the cross section of condom was changed concentrically, showing a "target ring" sign, a ring-shaped strong echo was found in the center of the target ring, or gas-liquid mixed echo. The outer circumference of the target ring alternately surrounds the multiple layers of strong and weak echoes. The thickness of the target ring is closely related to the number of layers of the intestine and the edema of the intestinal wall. The longitudinal section of the nested pile shows sleeve-like changes, showing a "sleeve" sign, the length in the range of 3.6 to 6.2cm. Finally, with reference to the characteristic changes of ultrasonic images in pediatric intussusception, it is concluded that the diagnosis of intussusception in children is reliable and accurate, and it is worthy of wide clinical application
