OBJECTIVE
This study was done to evaluate the role of real-time Elastography (ES) in the diagnosis and staging the severity of acute appendicitis.
METHODS
Forty patients with acute pain in the right iliac fossa were evaluated using ES and sonography. All patients with a diagnosis of acute appendicitis on ES were also staged for the severity of appendicular inflammation and later underwent surgery, and the findings on imaging were confirmed and results compared. The sensitivity and specificity for ES and sonography were then calculated.
RESULTS
Elastography had sensitivity and specificity of 100% each, whereas sonography had sensitivity of 88% and specificity of 100%. Elastography also depicted the severity of inflammation, with 12 patients having mild, 8 having moderate, and 5 having severe appendicitis.
CONCLUSIONS
Combining ES with sonography improves the sensitivity in detection of acute appendicitis and can also be used to triage the severity of inflammation in such patients.
目的
本研究旨在评估实时弹性成像（ES）在诊断和分期急性阑尾炎严重程度中的作用。
方法
对 40 例右髂窝疼痛的患者进行 ES 和超声检查。所有 ES 诊断为急性阑尾炎的患者均进行阑尾炎症严重程度分期，随后行手术治疗，并对影像学检查结果进行确认和比较。计算 ES 和超声的灵敏度和特异性。
结果
ES 的灵敏度和特异性均为 100%，而超声的灵敏度为 88%，特异性为 100%。ES 还可以显示炎症的严重程度，其中 12 例为轻度，8 例为中度，5 例为重度阑尾炎。
结论
将 ES 与超声相结合可以提高急性阑尾炎的检出灵敏度，还可以用于分诊此类患者的炎症严重程度。
