Sonography of the gastrointestinal (GI) tract is a practical, safe, inexpensive, and reproducible diagnostic tool for the evaluation, diagnosis, and follow-up of infectious bowel disease. The modality is rapidly gaining prominence among clinicians on a global scale. In the United States, however, ultrasound of the bowel remains underutilized primarily due to insufficient experience among radiologists and sonographers in performing sonographic bowel assessment. This lack of experience and knowledge results in misinterpretations, missed diagnoses, and underutilization of this modality in patients with acute abdomen, with the majority of GI pathology on sonography discovered incidentally.
This article aims to demonstrate the characteristic sonographic findings associated with GI infectious processes as well as provide dedicated ultrasound protocols for evaluation of the GI tract.
This article serves a twofold purpose, raising awareness of the utility of this imaging modality within the radiology community and also providing practical teaching points for sonographic evaluation of infectious disorders of the GI tract.
胃肠（GI）道超声检查是一种实用、安全、廉价且可重复的诊断工具，可用于评估、诊断和随访传染性肠道疾病。这种方式在全球范围内得到了临床医生的广泛关注。然而，在美国，由于放射科医生和超声科医生在进行超声肠道评估方面经验不足，肠道超声的应用仍然不足。这种经验和知识的缺乏导致了对肠道超声的误解、漏诊和低估，而在急性腹痛患者中，这种情况更为常见，大多数胃肠道疾病都是偶然发现的。
本文旨在展示与 GI 感染过程相关的特征性超声表现，并提供专门用于评估胃肠道的超声协议。
本文有两个目的，一方面是提高放射科医生对这种影像学方式的认识，另一方面是为胃肠道感染性疾病的超声评估提供实用的教学要点。
