Focal liver lesion is a common disease of liver, which represents a wide range of pathologic types. Its diagnosis is very difficult in some cases with trad... D Jing,H Lin - 《Progress in Modern Biomedicine》 被引量: 1发表: 2010年 The benefit of contrast-enhanced ultrasound in biopsies ...
Screening of the liver for hepatic lesion detection and characterization is usually performed with either ultrasound or CT. However, both techniques are su
Small liver lesions in oncologic patients: characterization with CT, MRI and contrast-enhanced US. Focal liver lesions (FLLs) are frequently discovered during ultrasound examinations either in healthy subjects without a clinical history of cancer or duri...

Liver metastases generally involve both lobes of the liver, occurring as a solitary lesion only 20% of the time.77 Liver metastases are most commonly associated with malignancy from the gastrointestinal tract (commonly the colon, esophagus, and stomach), pancreas (including neuroendocrine tumors), ...
Heat maps obtained from different feature layers with and without DSM from layers 1–4. (a) without DSM (b) with DSM. Full size image In contrast, with DSM (Fig. 5b), the highlight of the liver area at the shallow layer is significantly enhanced. As the layers of the network increase...
Nodules located in different liver segments were analysed separately with individual boluses of contrast. Within the same segment, only one target nodule was included for analysis based on best visualization criteria. CT and/or MRI, when typical for HCC or definitely benign (haemangioma, hepatic fat...
For diagnosis of hepatocellular carcinoma, dynamic contrast-enhanced MRI (DCE-MRI) can yield a higher sensitivity than contrast-enhanced CT. However, most studies on automatic liver lesion segmentation have focused on CT. In this study, we present a deep learning-based approach for liver tumor ...
Distinguishing FNH and hepatocellular adenoma (HCA) is important; HCAs can hemorrhage or transform into hepatocellular carcinoma, as described later. This is particularly important if the lesion is larger than 3 cm and subcapsular. For such patients, use of MRI with gadoxetate disodium is helpful ...
1,2,3 For liver lesion screening, contrast-enhanced computed tomography (CECT) has been clinically proven effective to assist diagnosis and surgery.4,5,6 Yet, it is time-consuming when manually performed on numerous CECTs.7,8,9 With the advent of the artificial intelligence (AI) era, ...
