Enhancement of Colorectal Carcinoma Liver Metastasis:Comparison of Contrast-Enhanced Ultrasound and Contrast-Enhanced Computed Tomography

Department of Ultrasound, Zhongshan Hospital, Fudan University, Shanghai 200032, China

摘要

摘要: 目的: 比较结直肠癌肝转移灶超声造影与增强CT血流灌注的异同。方法: 对比60例60个结直肠癌肝转移灶超声造影与增强CT动脉期及门脉期的增强表现。结果: 60个病灶超声造影动脉期均增强,53.3%(32/60)周边增强,46.7%(28/60)整体增强；增强CT见 78.3 %(47/60)的病灶周边增强,16.7%(10/60)整体增强,5%(3/60)未见增强(P＜0.01 )。动脉期病灶的增强程度方面,超声造影示93.3%(56/60)的病灶增强程度高于肝实质,6.7%(4/60)增强程度低于肝实质；增强CT示 91.2%(52/57)的病灶增强程度高于肝实质,8.8%(5/57)增强程度低于肝实质(P＞0.05)；门脉期,超声造影示100%(60/60)的病灶增强减退,较周围肝实质呈低回声,增强CT门脉期示 100%(60/60)的病灶较周围肝实质呈低密度,两种影像方法所示的转移灶增强程度均低于肝实质(P＞0.05)。结论: 结直肠癌肝转移灶的超声造影和增强CT增强表现不完全相同,超声造影在反映部分结直肠癌肝转移灶动脉血流灌注方面较增强CT有一定优势。

Abstract: Objective: To compare blood perfusion visibility of contrast-enhanced ultrasound (CEUS) in colorectal carcinoma (CRC) liver metastasis with contrast-enhanced computed tomography (CECT). Methods: Sixty cases of CRC liver metastasis in Zhongshan Hospital, Fudan University were enrolled in this study and were analyzed with both CEUS and CECT. Results: At arterial phase, 53.3%(32/60) lesions showed rim-like enhancement and 46.7% (28/60) lesions showed total enhancement on CEUS,while on CECT, rim-like enhancement, total enhancement and no enhancement were detected in 78.3% (47/60) lesions, 16.7% (10/60) lesions and 5% (3/60) lesions lesions, respectively (P＜0.01). At peak enhancement, 93.3% (56/60) lesions showed higher enhancement and 6.7% (4/60) lesions showed lower enhancement on CEUS,which were detected in 91.2%(52/57) lesions and 8.8%(5/57) lesions at arterial phase of CECT, respectively (P＞0.05). At portal venous phase, all lesions showed lower enhancement on both CEUS and CECT (P＞0.05). Conclusions: The blood perfusion appearance of CRC liver metastasis with CEUS is not identical as that of CECT. Among some cases, CEUS is superior to CECT on arterial perfusion visualization of liver metastasis.
