传统的超声内镜（EUS）在诊断实性肿块方面存在局限性。由于大多数被描述为低回声肿块，没有细胞学或活检，因此很难区分炎性肿块和恶性肿瘤。最近开发的对比增强谐波 EUS (CH-EUS) 通过描绘微血管和实质灌注改善了消化道病变的表征，特别是用于区分胰腺癌与其他胰腺实体病变、识别导管内乳头状粘液性肿瘤中的附壁结节以及估计胃肠道间质瘤的恶性潜力。 CH-EUS 与 EUS 引导的细针抽吸术互补，用于诊断胰腺病变、分期和预测化疗反应。
Conventional endoscopic ultrasonography (EUS) has limitations in the diagnosis of solid masses. Because most are depicted as a hypoechoic mass, without cytology or biopsy, it can be difficult to distinguish inflammatory masses from malignancy. Recently developed, contrast-enhanced harmonic EUS (CH-EUS) has improved characterization of digestive lesions by depicting microvessels and parenchymal perfusion, particularly for differentiating pancreatic cancer from other pancreatic solid lesions, identifying mural nodules in intraductal papillary mucinous neoplasms, and estimating malignant potential of gastrointestinal stromal tumors. CH-EUS is complementary to EUS-guided fine-needle aspiration for diagnosing pancreatic lesions, staging, and predicting chemotherapy response.
