Background: Balloon catheter isolation is a promising auxiliary method for thermal ablation treatment of liver cancer. We aimed to explore the safety and effectiveness of balloon catheter isolation-assisted ultrasound-guided percutaneous microwave ablation (MWA) in treating liver cancer in difficult anatomical locations.

Methods: Data of 132 patients with 145 difficult-site liver cancer treated with ultrasound-guided percutaneous MWA were retrospectively analyzed.

Clinical diagnostic value of contrast-enhanced ultrasound combined with microflow imaging in benign and malignant renal tumors: A retrospective cohort study.

This study aims to evaluate the clinical diagnostic value of contrast-enhanced ultrasound combined with microflow imaging (CEUS-MFI) in the differential diagnosis of benign and malignant renal tumors. All patients underwent CEUS, MFI, color doppler flow imaging (CDFI), and CEUS-MFI. The efficacies of these different diagnostic modalities in diagnosing benign and malignant renal tumors were evaluated by Kappa consistency test and the receiver operating characteristic (ROC) curve, with pathological findings serving as the gold standard.

Feasibility study of functional near-infrared spectroscopy in the ventral visual pathway for real-life applications.

Significance: fNIRS-based neuroenhancement depends on the feasible detection of hemodynamic responses in target brain regions. Using the lateral occipital complex (LOC) and the fusiform face area (FFA) in the ventral visual pathway as neurofeedback targets boosts performance in visual recognition. However, the feasibility of utilizing fNIRS to detect LOC and FFA activity in adults remains to be validated as the depth of these regions may exceed the detection limit of fNIRS.

Major complications after ultrasound-guided liver biopsy: An annual audit of a Chinese tertiary-care teaching hospital.

Background: As ultrasound-guided percutaneous liver biopsy (PLB) has become a standard and important method in the management of liver disease in our country, a periodical audit of the major complications is needed.

Aim: To determine the annual incidence of major complications following ultrasound-guided PLB and to identify variables that are significantly associated with an increased risk of major complications.

Methods: A total of 1857 consecutive cases of PLB were included in our hospital from January 2021 to December 2021.

Early stage of radiological expertise modulates resting-state local coherence in the inferior temporal lobe.

Background: The visual system and its inherent functions undergo experience-dependent changes through the lifespan, enabling acquisition of new skills. Previous fMRI studies using tasks reported increased specialization in a number of cortical regions subserving visual expertise. Although ample studies focused on representation of long-term visual expertise in the brain, i.

Deep learning for real-time auxiliary diagnosis of pancreatic cancer in endoscopic ultrasonography.

In recent year, many deep learning have been playing an important role in the detection of cancers. This study aimed to real-timely differentiate a pancreatic cancer (PC) or a non-pancreatic cancer (NPC) lesion endoscopic ultrasonography (EUS) image. A total of 1213 EUS images from 157 patients (99 male, 58 female) with pancreatic disease were used for training, validation and test groups.

Percutaneous ultrasound and endoscopic ultrasound-guided biopsy of solid pancreatic lesions: An analysis of 1074 lesions.

Backgrounds: Percutaneous ultrasound (US) and endoscopic ultrasound (EUS)-guided pancreatic biopsies are widely accepted in the diagnosis of pancreatic diseases. Studies comparing the diagnostic performance of US- and EUS-guided pancreatic biopsies are lacking. This study aimed to evaluate and compare the diagnostic yields of US- and EUS-guided pancreatic biopsies and identify the risk factors for inconclusive biopsies.

Irreversible electroporation in patients with liver tumours: treated-area patterns with contrast-enhanced ultrasound.

Background: Familiarity with post-IRE imaging interpretation is of considerable importance in determining ablation success and detecting recurrence. CEUS can be used to assess the tumour response and characteristics of the ablation zone. It is of clinical interest to describe the ultrasonographic findings of liver tumours after irreversible electroporation (IRE) percutaneous ablation.

Pre-operative Detection of Liver Fibrosis in Hepatocellular Carcinoma Patients Using 2D Shear Wave Elastography: Where to Measure?

The aim of this study was to pre-operatively investigate the diagnostic performance of 2D shear wave elastography (2D-SWE) for staging liver fibrosis and inflammation in patients with hepatocellular carcinoma (HCC) who then undergo surgery and to determine the optimal locations for measurement. In total, 106 patients were enrolled in this prospective study from March 2017 to May 2018. Two-dimensional SWE was used to measure liver stiffness (LS) in each patient 0-1, 1-2 and 2-5 cm from the tumor border (groups 1, 2 and 3, respectively).

Ultrasound and Contrast-enhanced Ultrasound Findings after Percutaneous Irreversible Electroporation of Hepatic Malignant Tumors.

The aim of this study was to describe ultrasound (US) and contrast-enhanced ultrasound (CEUS) findings immediately and 1 d after percutaneous irreversible electroporation (IRE) of hepatic malignant tumors. Immediately after IRE, the ablation zone was shown to be a gradually expanding hypo-echoic area around the electrodes. The microcirculation of the ablation zone was markedly reduced on CEUS (before vs.

Treatment response and preliminary efficacy of hepatic tumour laser ablation under the guidance of percutaneous and endoscopic ultrasonography.

Background: Studies focusing on the treatment effectiveness of endoscopic ultrasonography (EUS)-guided laser ablation (LA) for hepatic tumours or the technical differences from percutaneous ultrasonography (US)-guided LA are lacking. The objective of this study was to evaluate the treatment response and preliminary efficacy of US- and EUS-guided LA for hepatic tumours.

Methods: We performed a prospective analysis of treatment response and preliminary efficacy in 92 consecutive patients who underwent US-LA and EUS-LA from January 2015 to June 2017.

Percutaneous Laser Ablation of Hepatic Tumors Located in the Portacaval Space: Preliminary Results.

Background And Objectives: Limited data have been used to evaluate the feasibility and effectiveness of percutaneous laser ablation (PLA) (a modality that has been proven to be a safe method for tumors in high-risk locations) for hepatic tumors in the space between the portal vein and inferior vena cava (IVC). The goal of this study was to investigate the characteristics and therapeutic effectiveness of ultrasound-guided PLA of hepatic tumors in the portacaval space.

Study Design/materials And Methods: Ten patients, who had hepatic tumors in the portacaval space (defined as tumors located in the space formed by the hepatic portal vein and IVC less than 5 mm from the margins of both vessels), receiving ultrasound-guided PLA between January 2016 and June 2017 were analyzed.

Endoscopic ultrasonography (EUS)-guided laser ablation (LA) of adrenal metastasis from pancreatic adenocarcinoma.

Endoscopic ultrasonography (EUS)-guided laser ablation (LA) is potentially applicable to tumours in the left lobe of the liver and pancreas. This report seeks to introduce the novel use of EUS-guided LA for left adrenal metastases from pancreatic adenocarcinoma. A 70-year-old female was referred to our hospital for dull abdominal pain and tiredness for 1 month.

EUS dating with laser ablation against the caudate lobe or left liver tumors: a win-win proposition?

Endoscopic ultrasound (EUS) have been not only a diagnostic tool, but also available in interventional therapy, which often previously needed surgical approaches to achieve. The study aimed to evaluate the effectiveness and safety of EUS-guided Nd:YAG laser ablation in unresectable tumors of the caudate lobe and left liver. We discussed ten cases of the caudate lobe and left liver tumors underwent laser ablation with EUS guidance.
