通过磁共振成像 (MRI) 和计算机断层扫描 (CT) 对 30 名患者的 70 个包虫囊肿进行了研究；所有病例均经手术确诊。当局限于实体器官时，MRI 可以检测到所有囊肿，而当位于腹膜腔时，小尺寸囊肿 (≤2 cm) 可能会被漏掉。小于 3 厘米的包虫囊肿（非复杂性）没有包虫病的具体表现。 MRI 结果提示包虫病，表现为相对较厚的包虫囊壁、子囊和生发膜脱离。事实证明，T2 加权图像在显示包虫囊壁厚度、生膜脱离和子体囊肿方面优于 T1 或 PD 加权图像。在所有自旋回波序列中，母体囊肿内容物呈现出比子体囊肿高得多的信号强度。这种信号强度的差异在 T2 加权图像中更为明显，但复杂的感染病例除外。 CT 在显示壁钙化方面被证明优于 MRI。
Seventy hydatid cysts in 30 patients were studied with magnetic resonance imaging (MRI) and computed tomography (CT); all cases were confirmed surgically. MRI detected all cysts when confined to solid organs, whereas small-sized cysts (≤2 cm) may be missed when located in the peritoneal cavity. Hydatid cysts of less than 3 cm (noncomplicated) present no specific findings of hydatid disease. MRI findings suggesting hydatid disease demonstrate a relatively thick hydatid cyst wall, daughter cysts, and germinal membrane detachment. T2-weighted images proved to be superior to T1 or PD-weighted images in demonstrating hydatid cyst wall thickness, germinal membrane detachment, and daughter cysts. In all spin-echo sequences, the maternal cystic content presented much higher signal intensities than that of daughter cysts. This difference in signal intensity is more obvious in T2 weighted images, except in complicated, infected cases. CT proved to be superior to MRI in demonstrating wall calcifications.
