| 摘 要 目的 探究参量成像在不同程度的继发性甲状旁腺功能亢进的应用价值。方法 本研究回顾2021年1月至2021年9月在本院进行甲状旁腺常规超声和超声造影检查的SHPT患者56例，而后进行PI成像分析。根据血清iPTH结果分为轻中重三组，常规超声测量体积、内部回声后进行超声造影，用PI分析分析视频片段并测量最早到达时间（AT1）、最晚到达时间（AT1）和行程时间（△T），用TIC成像测量造影剂开始进入甲状旁腺时间（ATm）。PI的定量参数包括灌注模式（均匀、向心、离心、偏心）、增强均匀与否、有无非增强区及增强早晚。结果 在大体积SHPT造影后的测量造影剂开始进入时间更推荐使用PI成像。轻度和中度SHPT的PI表现大多以均匀性灌注模式为主，呈均匀增强；重度SHPT的PI表现以向心性灌注模式为主，呈不均匀增强。三组SHPT的PI表现为与甲状腺的造影剂进入几乎同步，轻度SHPT的AT1最早。结论 PI模型和定量参数有助于评估SHPT的严重程度。 |

| Abstract Objective To assess the severity of secondary hyperparathyroidism (SHPT) using contrast-enhanced ultrasound (CEUS) parametric imaging.Methods 56 SHPT patients who underwent conventional and CEUS examination of the parathyroid gland in our hospital from January 2021 to September 2021, followed by PI imaging analysis. They were divided into light, moderate and severe group as per parathyroid hormone (PTH). After conventional ultrasound measurement of volume and internal echo, CEUS was performed, then PI was used to analyze the video clips and the earliest Arrival Time (AT1), last Arrival Time (AT1) and travel time (△T) were measured. TIC imaging was used to measure the time of the contrast agent entering the parathyroid (ATm). The quantitative parameters of PI include the perfusion pattem (uniform, centripetal, centrifugal, eccentric), non-uniform, uniform enhancement, non-enhancement area and enhancement time.Results PI imaging is more recommended to measure the start time of contrast agent entry after mass SHPT imaging. The PI manifestations of light and moderate SHPT were mainly in uniform perfusion pattems, and showed uniform enhancement; The PI manifestations of severe SHPT were mainly centered perfusion pattern and showed uneven enhancement. PI of SHPT in the three groups was almost synchronous with the entry of thyroid contrast agent, and ArT1 of mild SHPT was the earliest.Conclusion The PI model and quantitative parameters can be benefit for the assessment the severity of SHPT. |
