Diagnostic value of color parametric imaging and contrast-enhanced ultrasound in the differentiation of hepatocellular adenoma and well-differentiated hepatocellular carcinoma.

Purpose: To investigate the differential diagnostic value of computer-aided color parametric imaging (CPI) and contrast-enhanced ultrasound (CEUS) in hepatocellular adenoma (HCA) and well-differentiated hepatocellular carcinoma (wHCC).

Method: A total of 38 patients who underwent CEUS and were pathologically diagnosed with HCA (10 cases) and wHCC (28 cases) were reviewed retrospectively. The differences between the radiological features of HCA and wHCC were compared by two readers, blinded to the final diagnosis.

Diagnostic Value of Arrival Time Parametric Imaging Using Contrast-Enhanced Ultrasonography in Superficial Enlarged Lymph Nodes.

Objective: The aim of this study was to evaluate the value of arrival-time parametric imaging for differential diagnosis of superficial enlarged lymph nodes.

Methods: Patients with lymphadenopathy who received contrast-enhanced ultrasonography (CEUS) and biopsy were included in this study. Following CEUS, a prototype software of the arrival-time parametric imaging system was used to analyze the video footage.

Diagnostic Value of Contrast-Enhanced Ultrasonography and Time-Intensity Curve in Differential Diagnosis of Cervical Metastatic and Tuberculous Lymph Nodes.

Objectives: To evaluate the diagnostic value of contrast-enhanced ultrasonography (CEUS) in the differential diagnosis of tuberculous and metastatic lymph nodes.

Methods: Nineteen cervical tuberculous lymph nodes and 43 cervical metastatic lymph nodes were investigated. The CEUS perfusion patterns and parameters of time-intensity curve (TIC) were analyzed.

Effects of Gray-Scale Ultrasonography Immediate Post-Contrast on Characterization of Focal Liver Lesions.

This study compared the imaging features of conventional gray scale ultrasound (US) before and after contrast-enhanced ultrasound (CEUS) for focal liver lesions and 22 evaluated the role of US post-CEUS in characterizing liver lesions. 126 patients with 158 focal liver lesions underwent CEUS and US post-CEUS examination and entered this study. There were 74 hepatocellular carcinomas (HCC), 43 hepatic metastases, and 41 hemangiomas.

Diagnosis of small hepatic nodules detected by surveillance ultrasound in patients with cirrhosis: Comparison between contrast-enhanced ultrasound and contrast-enhanced helical computed tomography.

Aim: To investigate the diagnostic value for the diagnosis of small (1-2 cm) hepatic nodules detected by surveillance ultrasound in patients with cirrhosis using contrast-enhanced ultrasound (CEUS) compared with that of contrast-enhanced helical computed tomography (CECT).

Methods: Seventy-two liver cirrhosis patients with 103 small hepatic nodules (1-2 cm) detected by surveillance ultrasound were enrolled in the present study. All patients underwent CEUS with SonoVue as well as CECT.

Focal liver lesions: can SonoVue-enhanced ultrasound be used to differentiate malignant from benign lesions?

Objective: To evaluate whether contrast-enhanced ultrasound (CEUS) with SonoVue could differentiate malignant focal liver lesions (FLLs) from benign lesions and provide lesion type diagnoses.

Materials And Methods: Four hundred fifty-six patients with 554 FLLs were examined by CEUS with SonoVue using low mechanical index, nonlinear imaging techniques. Each lesion was characterized by 2 independent off-site readers as malignant or benign and given specific lesion type diagnosis, if possible, both at baseline ultrasound (US) and after SonoVue administration (CEUS).

[The assessment of wall invasion of rectal carcinoma: correlation of endoluminal ultrasonographic and pathologic findings].

Objective: To evaluate the accuracy of endoluminal ultrasonography (ELUS) in the preoperative assessment of wall invasion of rectal carcinoma and analyze its influencing factors.

Methods: ELUS was performed preoperatively in 117 patients with rectal carcinoma, in which no preoperative treatment was given. The results of ELUS were correlated with operative and pathologic findings according to the TNM classification.

The role of contrast-enhanced sonography of focal liver lesions before percutaneous biopsy.

Objective: The objective of our study was to evaluate the clinical utility of performing contrast-enhanced sonography before percutaneous biopsy of focal liver lesions.

Subjects And Methods: One hundred eighty-six patients with focal liver lesions detected on either sonography or contrast-enhanced CT were randomly divided into two groups: a group who underwent contrast-enhanced sonography and another who underwent unenhanced sonography. The contrast-enhanced sonography group (79 patients, 129 lesions) underwent SonoVue-enhanced sonography before biopsy, and the unenhanced sonography group (107 patients, 143 lesions) did not undergo contrast-enhanced sonography before biopsy.

Evaluation of primary malignancies of the liver using contrast-enhanced sonography: correlation with pathology.

Objective: Our purpose was to investigate the correlation of contrast-enhanced sonographic patterns with the histopathology of primary malignancies of the liver.

Material And Methods: Of the 318 contrast-enhanced sonographic examinations performed between April and September 2004, 95 patients with 117 lesions confirmed by surgery or biopsy pathology were reviewed in this study. We analyzed the enhancement time and patterns according to the types and degrees of pathologic differentiation.

[Application of contrast-enhanced ultrasound to increase the diagnostic rate of liver tumor by biopsy].

Objective: To evaluate the clinical utility of contrast-enhanced ultrasound (CEUS) in percutaneous liver biopsy of focal liver lesions.

Methods: Two hundred and eleven patients with unidentified space occupying lesions in liver, 112 males and 74 females, aged 52 (16-78), were randomly divided into 2 groups: CEUS group in which 96 cases with 149 lesions underwent liver biopsy with 21-18 gauge needles directed by real time grey CEUS, and routine ultrasound (US) group in which 115 patients with 153 lesions underwent biopsy guided by conventional ultrasonography. There was no significant difference in the size of lesions between these 2 groups.

[Early diagnosis of small hepatocellular carcinoma by new contrast-enhanced ultrasound technique].

Objective: To investigate the diagnostic value of contrast-enhanced ultrasound (CEUS) enhancement patterns of hepatocellular carcinoma (HCC) smaller than 2 cm.

Methods: From 392 cases with focal liver lesions undergoing CEUS with SonoVue and Contrast Tuned Imaging (CnTI) technique, thirty six cirrhotic patients with thirty eight HCCs with histopathological diagnosis were retrospectively analyzed in this study. Surgery or needle biopsy was performed within fifteen days after CEUS.
