conclusions the incidence of liver abscesses after liver cancer thermal ablation is low. child-pugh class b and class c cirrhosis, biliary tract disease, diabetes mellitus, and porta hepatis tumors are four significant risk factors. combined ablation and pei reduces the rate of liver abscesses. background radiofrequency ablation (rfa) and microwave ablation (mwa) are the most frequently used th...

Background: Irreversible electroporation (IRE) is a novel tumor ablation technique. IRE is associated with high electrical fields and is often reported in conjunction with thermal damage caused by Joule heating. For good response to surgery it is crucial to produce minimum thermal damage in both tumoral and healthy tissues named Non-Thermal Irreversible Electroporation(NTIRE). Non-thermal irrev...

introduction: one of the minimally invasive methods of treatmenting liver malignancies is radiofrequency ablation (rfa) which can be applied to primary or secondary tumors. nevertheless, the disease recurrence is probable after rfa application partially due to the inadequate capability of temperature monitoring of the target tissue and visualizing the thermal damage. the goal of this work was t...

background: the rationale was to develop an ablation approach to destroy regions of tumor resistant to radiation and thus reduce the time required for whole tumor ablation, while improving overall tumor control after radiotherapy. materials and methods: the system is composed of a micro positron emission tomography (mpet), 7t magnetic resonance imaging (mri), and a customized mri-compatible foc...

thermal ablation therapies for benign thyroid nodules have been introduced in recent years to avoid the complications of traditional methods such as surgery. despite the little complications and the reportedly acceptable efficacy of thermal ablation methods, quite few medical centers have sought the potential benefits of employing them. this paper provides an introduction to the literature, pri...

BACKGROUND Primary or metastatic osseous and soft tissue lesions can be treated by ablation techniques. METHODS These techniques are classified into chemical ablation (including ethanol or acetic acid injection) and thermal ablation (including laser, radiofrequency, microwave, cryoablation, radiofrequency ionisation and MR-guided HIFU). Ablation can be performed either alone or in combination...

OBJECTIVE To evaluate the cost difference between a daycase endometrial thermal ablation performed under general anaesthesia and an outpatient endometrial ablation using local anaesthetic. STUDY DESIGN Calculations using real reported resource use in 20 daycase procedures and 16 outpatient procedures. RESULTS The costs were 1865 euros for daycase procedure versus 1065 euros for outpatient p...

The feasibility of using ultrasound-based elastic modulus imaging to visualize thermal ablation zones in an in vivo porcine model is reported. Elastic modulus images of soft tissues are estimated as an inverse optimization problem. Ultrasonically measured displacement data are utilized as inputs to determine an elastic modulus distribution that provides the best match to this displacement field...
