Quantitative and noninvasive assessment of chronic liver diseases using two-dimensional shear wave elastography.

Two-dimensional shear wave elastography (2D-SWE) is a rapid, simple and novel noninvasive method that has been proposed for assessing hepatic fibrosis in patients with chronic liver diseases (CLDs) based on measurements of liver stiffness. 2D-SWE can be performed easily at the bedside or in an outpatient clinic and yields immediate results with good reproducibility. Furthermore, 2D-SWE was an efficient method for evaluating liver fibrosis in small to moderately sized clinical trials.

Application of superb microvascular imaging in focal liver lesions.

Aim: To explore the ability of superb microvascular imaging (SMI) in differential diagnosis of focal liver lesions (FLLs) and to compare SMI morphology findings to those of color Doppler ultrasound and enhanced imaging.

Methods: Twenty-four patients with 31 FLLs were included in our study, with diagnoses of hemangioma (HE) ( = 17), hepatocellular carcinoma (HCC) ( = 5), metastatic lesions ( = 5), primary hepatic lymphoma ( = 1), focal nodular hyperplasia (FNH) ( = 2), and adenoma ( = 1). Nine lesions were pathologically diagnosed, and 22 lesions were radiologically confirmed, all of which were evaluated by at least two types of enhanced imaging techniques.

Research Advances in Clinical and Imaging Characteristics of Intraductal Papillary Mucinous Neoplasm of the Bile Duct.

Understanding on the intraductal papillary mucinous neoplasm of the pancreas (IPMN-P) has dramatically improved in the past three decades. A new disease named intraductal papillary mucinous neoplasm of the bile duct (IPMN-B) reported in recent years shares several similar clinical features with IPMN-P. The clinical manifestations and imaging characteristics of IPMN-B have been gradually recognized.

Value of Acoustic Radiation Force Impulse Imaging in the Diagnosis of Early Non-alcoholic Steatohepatitis.

Objective To evaluate the value of acoustic radiation force impulse(ARFI)imaging in the diagnosis of early non-alcoholic steatohepatitis(NASH).Methods Totally 32 SD rats were randomly divided into high-fat diet group(n=24)and normal-diet group(n=8)by using the random number table. At the end of the 4,8,12,and 16 week,six rats from the high-diet group and two rats from the normal-diet group were selected blindly for weighting,blood biochemical test,conventional ultrasound,and ARFI imaing.

Value of Contrast-enhanced Ultrasound for Small Focal Liver Lesions.

Objective To explore the diagnostic value of contrast-enhanced ultrasound (CEUS)for small focal liver lesions (FLLs). Methods The clinical data,CEUS findings,and pathology of 69 patients with small FLLs were retrospectively analyzed. Patients were grouped according to size of FLLs and the performance of CEUS was compared.
