Most imaging of the liver is performed to evaluate focal disease. MR imaging contrast media development likewise has centered on enhanced capability to eva... PF Hahn,S Saini - 《Radiologic Clinics of North America》 被引量: 210发表: 1998年 Liver-specific agents for contrast-enhanced MRI: role...
A special emphasis is placed on the clinical use of non-specific and liver-specific contrast agents for differentiation of focal liver lesions. This may aid in the accurate diagnostic workup of patients in order to avoid invasive procedures, such as biopsy, for lesion characterization. A ...
3.动态对比增强磁共振成像(dynamic contrast enhancement magnetic resonance imaging,DCE-MRI)(证据级别:中,推荐强度:弱): 肝纤维化的进展伴随着肝内血流动力学和血管微环境的改变,且血流动力学改变早于形态学改变,准确检测肝纤维化的...
(HCC) lesion segmentation. Methods: The proposed deep learning model utilizes 4D information on dynamic contrast enhanced (DCE) magnetic resonance imaging (MRI) images to assist liver tumor segmentation. Specifically, a shallow U-net based 3D CNN module was designed to extract 3D spatial domain ...
To determine whether dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) could monitor progression of liver fibrosis in a piglet model, and which DCE-MRI parameter is most accurate for staging this disease.Materials and MethodsSixteen piglets were prospectively used to model liver fibrosis ...
These TPE-2Gd nanoparticles can be excreted gradually via renal filtration due to the disassembly of the nanoparticles into small molecules during circulation. TPE-2Gd could thus potentially be used as a liver specific MRI contrast agent for clinical diagnosis. 展开 ...
