摘要

目的：使用 18 MHz 探头的高频超声（18 MHz-HFUS）在评估周围神经损伤（PNI）方面发挥着重要作用。使用 70-MHz 探头的超高频超声（70 MHz-UHFUS）具有更高的空间分辨率，可以更好地检测 PNI。本研究旨在比较高频超声和超高频超声在 PNI 检测中的诊断性能：在这项回顾性研究中，选取了 2022 年 7 月至 2024 年 4 月间因临床怀疑外伤性前臂 PNI 而接受 HFUS、UHFUS 和神经传导研究（NCS）的 61 例患者。计算并比较了 HFUS 和 UHFUS 检测 PNI 的敏感性、特异性、阳性预测值（PPV）、阴性预测值（NPV）和诊断准确性。NCS 被用作参考标准。采用非参数统计检验。结果比较 PNI 检测的诊断性能，70 MHz-UHFUS 的灵敏度和诊断准确性明显高于 18 MHz-HFUS，分别为 98.0% 对 82.4% (p = 0.0205) 和 95.1% 对 82.0% (p = 0.0468)。除此之外，特异性、PPV 和 NPV 均无明显差异：结论：与 HFUS 相比，UHFUS 在 PNI 检测中表现出更高的灵敏度和诊断准确性。

The Role of 70-MHz Ultrahigh-Frequency Ultrasound in the Peripheral Nerve Injury.

Aim: High-frequency ultrasound with an 18-MHz probe (18 MHz-HFUS) plays a relevant role in the evaluation of peripheral nerve injury (PNI). Ultrahigh-frequency ultrasound with a 70-MHz probe (70 MHz-UHFUS) offers higher spatial resolution and could allow a better detection of PNI. This study aimed to compare the diagnostic performance of HFUS and UHFUS in PNI detection.

Materials and methods: In this retrospective study, were selected, between July 2022 and April 2024, 61 patients underwent HFUS, UHFUS, and nerve conduction study (NCS) for clinical suspicion of traumatic forearm PNI. Sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and diagnostic accuracy of HFUS and UHFUS in PNI detection were calculated and compared. NCS was used as the reference standard. Nonparametric statistical tests were used. A p value of < 0.05 was considered statistically significant.

Results: Comparing the diagnostic performance in PNI detection, the 70 MHz-UHFUS showed a sensitivity and diagnostic accuracy significantly higher than 18 MHz-HFUS, respectively, 98.0% versus 82.4% (p = 0.0205) and 95.1% versus 82.0% (p = 0.0468). Otherwise, not significantly difference were in specificity, PPV, and NPV.

Conclusions: UHFUS compared to HFUS demonstrated a higher sensitivity and diagnostic accuracy in PNI detection.

期刊介绍： The Journal of Clinical Ultrasound (JCU) is an international journal dedicated to the worldwide dissemination of scientific information on diagnostic and therapeutic applications of medical sonography. The scope of the journal includes--but is not limited to--the following areas: sonography of the gastrointestinal tract, genitourinary tract, vascular system, nervous system, head and neck, chest, breast, musculoskeletal system, and other superficial structures; Doppler applications; obstetric and pediatric applications; and interventional sonography. Studies comparing sonography with other imaging modalities are encouraged, as are studies evaluating the economic impact of sonography. Also within the journal''s scope are innovations and improvements in instrumentation and examination techniques and the use of contrast agents. JCU publishes original research articles, case reports, pictorial essays, technical notes, and letters to the editor. The journal is also dedicated to being an educational resource for its readers, through the publication of review articles and various scientific contributions from members of the editorial board and other world-renowned experts in sonography.
