To study the density of lesions in the lumens of extrahepatic bile ducts through computed tomography examinations, and to compare their characterisations with the results of pathology and/or endoscopic retrograde cholangiopancreatography (ERCP).
The density of lesions along extrahepatic bile ducts were measured and compared with pathology and/or ERCP. The lesions were evaluated in two main groups: benign or malignant. The bile duct wall enhancement, intrahepatic bile ducts, and gallbladder were also evaluated.
The study was conducted with computed tomography scans of 197 cases (93 females, 104 males) who had optimal imaging. The results regarding density of extrahepatic intraductal lesions that were studied at BT were compared with pathology and magnetic resonance cholangiopancreatography results. Of 197 lesions, 125 (63.5%) were reported as benign and 72 (36.5%) were reported as malignant. The results for benign lesions showed an average density of 66.67 ± 17.30 Hounsfield units (HU), and for malignant lesions the average density was 82.38 ± 13.67 HU.
Lesion density level (HU) gives valuable information for the differentiation between benign and malign lesions in intraluminal extrahepatic bile ducts.
通过计算机断层扫描检查研究肝外胆管管腔内病变的密度，并将其特征与病理结果和/或内镜逆行胰胆管造影（ERCP）结果进行比较。
测量肝外胆管沿线病变的密度，并与病理结果和/或ERCP结果进行比较。病变主要分为两组进行评估：良性或恶性。同时对胆管壁强化、肝内胆管和胆囊进行评估。
对197例（93例女性，104例男性）进行了最佳成像的计算机断层扫描。将在BT研究的肝外导管内病变的密度结果与病理结果和磁共振胰胆管造影结果进行比较。在197个病变中，125个（63.5%）报告为良性，72个（36.5%）报告为恶性。良性病变的平均密度为66.67±17.30亨氏单位（HU），恶性病变的平均密度为82.38±13.67 HU。
病变密度水平（HU）为肝外胆管管腔内良性和恶性病变的鉴别提供了有价值的信息。
