PURPOSE: The objective of this study is to develop a computational model for simulating 915 MHz microwave ablation (MWA), and verify the simulation predictions of transient temperature profiles against experimental measurements. Due to the limited experimental data characterizing temperature-dependent changes of tissue dielectric properties at 915 MHz, we comparatively assess two temperature dependent approaches of modeling of dielectric properties: model A- piecewise linear temperature dependencies based on existing, but limited, experimental data, and model B- similar to model A, but augmented with linear decrease in electrical conductivity above 95 °C, as guided by our experimental measurements...

Breast cancer is the leading cause of cancer related deaths in women and one of the most common cancers globally. The major obstacle in the management of breast cancer, especially at advanced stages, is metastasis. Metastasis in the advanced stages of breast cancer could decrease survival to approximately 5 years. The reasons could include lack of targeted receptors or chemotherapeutic agents for the management of advanced-stage breast cancer metastasis. The new emerging avenues for the management of this deadly pathological state include local manipulations like radiofrequency ablation (RFA), microwave thermotherapy, cryosurgery (cryotherapy), chemoembolization, radioembolization, breast surgery, or metastasectomy...

Background Image-guided thermal ablation can be used for the treatment of medically inoperable primary and metastatic lung cancer. These techniques are based on the heating up or freezing (cryoablation) of a volume of tissue around a percutaneous applicator that induces necrosis of the tumor. Method The English-language literature concerning thermal ablation of the lung was reviewed. Radiofrequency ablation (RFA) is the most widely performed and investigated of these techniques. Microwave ablation (MWA) represents a relatively new alternative that shares the same indications and is conducted in a very similar fashion as RFA...

Image-guide thermal ablations are nowadays increasingly used to provide a minimally invasive treatment to patients with renal tumours, with reported good clinical results and low complications rate. Different ablative techniques can be applied, each with some advantages and disadvantages according to the clinical situation. Moreover, percutaneous ablation of renal tumours might be complex in cases where there is limited access for image guidance or a close proximity to critical structures, which can be unintentionally injured during treatment...

Interventional radiology plays a major role in the modern management of liver cancers, in primary hepatic malignancies or metastases and in palliative or curative situations. Radiological treatments are divided in two categories based on their approach: endovascular treatment and direct transcapsular access. Endovascular treatments include mainly three applications: transarterial chemoembolization (TACE), transarterial radioembolization (TARE) and portal vein embolization (PVE). TACE and TARE share an endovascular arterial approach, consisting of a selective catheterization of the hepatic artery or its branches...

Takotsubo cardiomyopathy (TCMP) is characterized by transient and reversible left ventricular regional wall motion abnormalities triggered by acute and intense emotional or physical stress. We present a case of a 79 year old woman with a hypertensive crisis after microwave ablation (MWA) for metastatic liver lesions. Initial evaluation suggested an acute coronary syndrome with an ST segment elevation and with elevated serum troponin T. No associated chest pain or dyspnea was present. Further evaluation with ECG, echocardiography, coronarography with left ventricle angiogram and MRI was consistent with an apical ballooning syndrome...
