the imaging of hepatocellular carcinoma (hcc) is challenging and plays a crucial role in the diagnosis and staging of the disease. a variety of imaging modalities, such as ultrasound, computed tomography (ct), magnetic resonance imaging (mri) and nuclear medicine are currently used in evaluating patients with hcc. although the best option for the treatment of these cases is hepatic resection or...
Microwave Ablation 2,2′-Azobis(2-[2-imidazolin-2-yl]propane) dihydrochloride (AIPH)-loaded temperaturesensitive liposomes can be well accumulated in the tumor site after intravenous injection. In article 2202947 by Hu Peng, Zhengbao Zha, and co-workers, when is exposed to environment of microwave thermal ablation, release loaded AIPH decomposes produce cytotoxic free radicals. Tumor growth effe...
The current fastest frame rate of each single image slice in MR-guided ablation is 1.3 seconds, which means delayed imaging for human at an average reaction time: 0.33 seconds. The delayed imaging greatly limits the accuracy of puncture and ablation, and results in puncture injury or incomplete ablation. To overcome delayed imaging and obtain real-time imaging, the study was performed using a 1...
Objective To determine the relative effectiveness of second generation ablation techniques in the treatment of heavy menstrual bleeding. Design Network meta-analysis on the primary outcome measures of amenorrhoea, heavy bleeding, and patients’ dissatisfaction with treatment. Data sources Nineteen randomised controlled trials (involving 3287 women) were identified through electronic searches of ...
Background Radiofrequency (RF) ablation is commonly used in the treatment of surgically unresectable hepatic tumors. It is amenable to open, laparoscopic, or percutaneous application, it makes use of well-understood principles of electrical and thermal heating of tissue, and it is readily available. However, local recurrence rates following RF ablation are as high as 39%. Microwave (MW) ablatio...
PURPOSE To retrospectively review the results of hepatocellular carcinoma (HCC) treatment with a high-power, gas-cooled, multiantenna-capable microwave device. MATERIALS AND METHODS A total of 107 HCCs in 75 patients (65 men) with a mean age of 61 years (range, 44-82 y) were treated via percutaneous approach. Combination microwave ablation and transarterial chemoembolization was performed for...
OBJECTIVE The purpose of this article is to evaluate MRI-guided therapies and to investigate their feasibility for focal therapy in prostate cancer patients. Relevant articles were retrieved using the PubMed online search engine. CONCLUSION Currently, MRI-guided laser ablation and MRI-guided focused ultrasound are the most promising options for focal treatment of the prostate in patients with...
PURPOSE To investigate the feasibility, safety and efficacy of ultrasound guided percutaneous microwave (MW) ablation for small splenic metastasis. MATERIALS AND METHODS A total of four patients with five pathologically proven splenic metastases (from ovarian, pulmonary, gastric adenocarcinoma and hepatocellular carcinoma, respectively) 1.3 to 2.9 cm in diameter were treated with microwave ab...
Since the introduction of radiofrequency ablation (RFA) for the treatment of liver tumors at the end of the 1990s, indications for local ablation techniques have been extended to other organs, in particular, the lungs, kidneys and bones. These techniques have also been improved, in particular to try and overcome the limitations of radiofrequency techniques, especially the significant decrease i...
