All patients underwent CEUS examination and some of them underwent positron emission tomography/computed tomography (PET/CT) examination simultaneously.

Real-time elastography evaluation of differential penetrating liver trauma in a rabbit model.

Background: Real-time ultrasound elastography (RTE) is used to examine liver fibrosis and benign and malignant lesions, but its use for the diagnosis of liver trauma has not been examined. The purpose of this study was to examine the use of RTE for the evaluation of differential penetrating liver trauma in a rabbit model.

Material And Methods: Eighty New Zealand rabbits were divided into 2 groups.

Comparison of transcutaneous contrast-enhanced ultrasound-guided injected hemostatic agents with traditional surgery treatment for liver, spleen and kidney trauma: a retrospective study.

Background/aims: There is lack of studies on the effectiveness of transcutaneous contrast-enhanced ultrasound-guided injections of hemostatic agents for liver. spleen and kidney trauma. We compared treatment by hemostatic agents to surgical treatment in a retrospective interventional human study.

Laparoscopic ultrasound enhances diagnosis and localization of insulinoma in pancreatic head and neck for laparoscopic surgery with satisfactory postsurgical outcomes.

This study explored the value of laparoscopic ultrasonography (LUS) for tumor localization in laparoscopic pancreatic surgery of insulinomas, especially for tumors located at anatomically unfavorable positions. Twenty-eight patients with insulinomas were enrolled in this study between July 2007 and March 2009. Various image examinations were performed preoperatively.

[Localization diagnosis of laparoscopic ultrasonograph in laparoscopic surgery of insulinoma].

Objective: To discuss the localization diagnosis value of laparoscopic ultrasonography in laparoscopic surgery of insulinoma.

Methods: Retrospectively reviewed the results of laparoscopic ultrasonography in 32 patients from Jan 2007 to Aug 2008 with insulinoma which confirmed after surgery, and analyzed the detection rate of laparoscopic ultrasonography.

Results: Insulinoma tumors were success located in 31 patients among 32 patients by laparoscopic ultrasonography.

Assessment of contrast-enhanced ultrasonography in diagnosis and preoperative localization of insulinoma.

Objective: This study was to evaluate the value of contrast-enhanced ultrasonography (CEUS) in the diagnosis and preoperative localization of insulinoma and explore the enhancement patterns of the tumors.

Methods: Unenhanced and contrast-enhanced ultrasonographic examinations of 31 patients who underwent resection of insulinomas were retrospectively reviewed. The diagnosis sensitivity and localization specificity of CEUS for insulinomas were determined.

Focal hypoechoic tumors of Fatty liver: characterization of conventional and contrast-enhanced ultrasonography.

Objective: The purpose of this study was to investigate the characteristics of focal hypoechoic tumors of fatty liver using conventional ultrasonography and contrast-enhanced ultrasonography (CEUS).

Methods: Sixty-four hypoechoic tumors of fatty liver in 52 patients were examined by both conventional ultrasonography and CEUS. Contrast pulse sequencing and a sulfur hexafluoride contrast agent were used for CEUS.

Laparoscopic surgery for pancreatic insulinomas: a single-institution experience of 29 cases.

Background: Laparoscopic approach has been increasingly used in the treatment of pancreatic benign diseases. This report evaluates our experience with laparoscopic surgery for pancreatic insulinomas.

Methods: Between July 2000 and December 2007, laparoscopic pancreatectomy was attempted in 29 consecutive patients with insulinomas.

Contrast-enhanced sonographic guidance for local injection of a hemostatic agent for management of blunt hepatic hemorrhage: a canine study.

Objective: The purpose of this study was to determine whether injection of hemostatic agents directly into an injury site under the guidance of contrast-enhanced sonography can effectively control hemorrhage due to hepatic trauma.

Materials And Methods: Fifteen mixed-breed dogs 2-3 years old and weighing 17-20 kg were anesthetized with intramuscular pentobarbital sodium (30 mg/kg). A special impacting device was used to induce hepatic trauma with a mean force of 5.

Undetermined focal liver lesions on gray-scale ultrasound in patients with fatty liver: characterization with contrast-enhanced ultrasound.

Background And Aim: The purpose of this study was to assess the clinical value and potential impact of contrast-enhanced ultrasound (CEUS) in the characterization of undetermined focal liver lesions (FLLs) in patients with fatty liver.

Methods: Fifty-two patients (34 men, 18 women) with fatty liver with 67 FLLs (size range, 1-8.6 cm; mean, 4.

Percutaneous injection of hemostatic agents for severe blunt hepatic trauma: an experimental study.

This study was designed to evaluate whether percutaneous injection of hemostatic agents under the guidance of contrast-enhanced ultrasound (CEUS) can stop hemorrhage from severe hepatic trauma. Eighteen dogs were impacted by a miniature impactor to create blunt hepatic trauma. Fourteen with appropriate liver lesions were divided into two groups: the treatment group (n = 7) and the control group (n = 7).

Contrast-enhanced ultrasound-guided microwave tissue coagulation therapy for hepatic trauma: an experimental study.

Background: Nonoperative therapies for hepatic trauma have become more popular. Because there is a potential application of microwave tissue coagulation (MTC) in the minimally invasive management of hepatic trauma, this study aimed to evaluate the efficacy of contrast-enhanced ultrasound (CEUS)- guided MTC therapy for hepatic trauma.

Methods: Forty hepatic lacerations were created intraoperatively in 10 heparinized porcine livers.

The value of contrast-enhanced gray-scale ultrasound in the diagnosis of hepatic trauma: an animal experiment.

Background: Conventional ultrasonography (US) shows markedly lower sensitivity in detecting parenchymal injury and active bleeding in abdominal organs. This study was designed to evaluate the utility of contrast-enhanced US (CEUS) in the diagnosis of blunt trauma and active hemorrhage of the liver in an animal model.

Methods: Sixteen blunt injuries and 40 lacerations with active hemorrhage were created in livers of 14 pigs using laparotomy.

Contrast-enhanced ultrasonography for assessment of tumor vascularity in hepatocellular carcinoma.

Objective: Studies have shown that angiogenesis is a critical factor for tumor growth and metastasis in a variety of human tumors. Although various methods have been tried to assess vessels in tumors, including microvessel density (MVD), assessment of tumor vessels by radiologic techniques is not well established. The aim of this study was to investigate the efficacy of contrast-enhanced ultrasonography (CEUS) in determining the tumor vascularity of hepatocellular carcinoma (HCC).
