Endoscopic ultrasound imaging technology has significantly improved over the last decade. Innovative design of equipment and devices has broadened the utility of EUS as diagnostic and therapeutic tools. Lesions as small as 3 mm can be imaged and targeted for endoscopic ultrasound-guided fine needle aspiration (EUS-FNA). EUS imaging with the latest generation electronic radial and linear scopes is excellent and does not vary significantly between models. Miniprobes should not be used in place of routine EUS echoendoscopes when available and technically feasible. The drawbacks of ultrasound miniprobes are the inability to perform fine needle aspiration and the limited depth of imaging. Transpapillary intraductal ultrasound (IDUS) improves staging of biliary tumors and improves imaging of biliary and pancreatic duct strictures. Endoscopic ultrasound-guided celiac plexus neurolysis or block (EUS-CPN/CPB) can be performed with the EUS-FNA needle or a specially designed celiac plexus block needle which distributes the neurolytic agent into the celiac plexus in a radial fashion. Use of the core biopsy needle is safe and should be used with a therapeutic linear scope through the gastric wall.
在过去十年中，内镜超声成像技术有了显著进步。设备和器械的创新设计拓宽了内镜超声作为诊断和治疗工具的用途。小至3毫米的病变都能成像，并可用于内镜超声引导下细针穿刺抽吸术（EUS-FNA）。使用最新一代电子径向和线性探头进行的内镜超声成像效果极佳，不同型号之间差异不大。在有条件且技术可行时，不应使用微型探头替代常规的内镜超声内镜。超声微型探头的缺点是无法进行细针穿刺抽吸，且成像深度有限。经乳头胆管内超声检查（IDUS）可改善胆管肿瘤的分期，并提高胆管和胰管狭窄的成像效果。内镜超声引导下腹腔神经丛神经溶解术或阻滞术（EUS-CPN/CPB）可使用EUS-FNA针或专门设计的腹腔神经丛阻滞针进行，该针以放射状将神经溶解剂注入腹腔神经丛。使用粗针活检针是安全的，应通过胃壁与治疗性线性探头配合使用。
