Abstract：
Ultrasound elastography is gaining attention for its diagnostic potential across various medical fields, and its physical properties make it valuable in modern clinical medicine. However, its specific attributes, especially in the context of recent medical advancements, remain relatively unexplored. This study aimed to identify instrument-specific characteristics and applications of real-time ultrasound elastography, shear wave elastography, and strain elastography, particularly within gastroenterology. Following PRISMA guidelines, the study examined elastography articles on databases like PubMed, resulting in 78 included articles. Data on patient demographics, organ involvement, specificity, sensitivity, accuracy, positive predictive value, and negative predictive value were extracted. Statistical analysis involved SPSS version 21, with significance set at p < 0.05. The majority of patients were male (50.50%), with a mean age of 42.73 ± 4.41 years. Shear wave elastography was the most prevalent technique (48.7%), and liver investigations were predominant in gastroenterology (34.6%). Gastrointestinal applications showed higher sensitivity, positive predictive value, and negative predictive values (p < 0.05) but lower specificity (p < 0.05). Real-time ultrasound elastography exhibited increased specificity, accuracy, and predictive values (p < 0.05). Ultrasound elastography appears more accurate and effective in gastroenterological settings. Nonetheless, its performance depends on instrument-specific and operator-dependent factors. While promising, further studies are necessary to ascertain optimal utilization in both gastrointestinal and non-gastrointestinal conditions.
摘要：
超声弹性成像因其在各个医学领域的诊断潜力而受到关注，及其物理性质使其在现代临床医学中具有重要价值。然而,它的特定属性，特别是在最近医学进步的背景下，相对未被探索。本研究旨在识别实时超声弹性成像的仪器特定特征和应用。剪切波弹性成像，应变弹性成像，特别是在胃肠病学中。按照PRISMA准则,这项研究检查了PubMed等数据库上的弹性成像文章，共收录了78篇文章。患者人口统计数据，器官受累,特异性，灵敏度,准确度,正预测值，提取阴性预测值。统计学分析涉及SPSS版本21,显著性设置为p<0.05。大多数患者为男性（50.50％），平均年龄42.73±4.41岁。剪切波弹性成像是最普遍的技术(48.7%)，和肝脏检查在胃肠病学中占主导地位（34.6％）。胃肠道应用显示出更高的灵敏度，正预测值，阴性预测值(p<0.05)，但特异性较低(p<0.05)。实时超声弹性成像显示特异性增加，准确度,和预测值(p<0.05)。超声弹性成像在胃肠道环境中似乎更准确和有效。尽管如此，它的性能取决于仪器特定和操作员依赖的因素。虽然有希望，需要进一步的研究来确定在胃肠道和非胃肠道疾病中的最佳利用。
