To evaluate the clinical utility of two dimensional (2D) ultrasound combined with spatiotemporal image correlation (STIC) in diagnosing interrupted aortic arch (IAA) in fetal life.
A total of 53 cases of fetal IAA were diagnosed using 2D ultrasound combined with STIC, and 53 normal fetuses of the same gestational week were selected. These cases were retrospectively analyzed to assess the utility of employing 2D ultrasound combined with STIC in the diagnosis of IAA.
2D ultrasound combined with STIC detected 22 cases of type A IAA, 24 cases of type B IAA, and seven cases of type C IAA. Furthermore, combining 2D ultrasound with STIC enabled dynamic visualization of the IAA, aiding in prenatal diagnosis. The diagnostic coincidence rate of IAA was found to be higher in the HD-flow combined with STIC than that in the 2D combined with HD-flow.
HD-flow combined with STIC can assist in diagnosing fetal IAA, and this technique has important clinical value.
评估二维（2D）超声联合时空关联成像（STIC）技术在胎儿主动脉弓中断（IAA）中的临床应用价值。
采用二维超声联合时空关联成像技术对 53 例胎儿 IAA 进行诊断，并选取同期 53 例正常胎儿作为对照，回顾性分析二维超声联合时空关联成像技术在诊断胎儿 IAA 中的应用价值。
二维超声联合时空关联成像技术共检出 22 例 A 型 IAA、24 例 B 型 IAA 和 7 例 C 型 IAA。同时，二维超声联合时空关联成像技术还可对 IAA 进行动态可视化，有助于产前诊断。与二维联合高分辨率血流（HD-flow）成像比较，HD-flow 联合 STIC 对 IAA 的诊断符合率更高。
HD-flow 联合 STIC 有助于诊断胎儿 IAA，具有重要的临床应用价值。
