Abdominal imaging studies may be performed for various indications in patients known to have sarcoidosis. To assess magnetic resonance imaging (MRI) and sonographic ability to detect abnormalities in sarcoidosis patients with abdominal involvement, a prospective study on 18 selected patients was performed. Besides organomegaly, when present, ultrasound demonstrated normal or increased hepatic parenchymal echogenicity, coarsening of the liver parenchyma with or without discrete nodules, focal calcifications, as well as contour irregularity. Splenic discrete nodules were seen on ultrasound in a single patient. Besides organomegaly, MRI abnormalities include abnormal hepatic signal intensity, discrete nodules, contour irregularity, speculation of small hepatic vascular branches, and a high periportal signal intensity. MRI splenic abnormalities include contour irregularity, nodularity, and abnormal signal intensity. The data presented in this study reveals the spectrum of ultrasound and MRI findings in sarcoidosis patients with abdominal organ involvement, potentially enabling the evaluation of the severity of the disease. MRI appears more sensitive than ultrasound for study of abdominal sarcoidosis.
对于已知患有结节病的患者，可出于各种指征进行腹部影像学检查。为评估磁共振成像（MRI）和超声检测腹部受累结节病患者异常情况的能力，对18例选定患者进行了一项前瞻性研究。除了器官肿大（若存在）外，超声显示肝实质回声正常或增强、肝实质粗糙伴或不伴离散结节、局灶性钙化以及轮廓不规则。在一名患者的超声检查中发现了脾脏离散结节。除了器官肿大外，MRI异常包括肝脏信号强度异常、离散结节、轮廓不规则、肝小血管分支增粗以及门静脉周围高信号强度。MRI脾脏异常包括轮廓不规则、结节状以及信号强度异常。本研究呈现的数据揭示了腹部器官受累结节病患者的超声和MRI表现范围，可能有助于评估疾病的严重程度。对于腹部结节病的研究，MRI似乎比超声更敏感。
