ABSTRACT Endovascular aneurysm repair is an established technique for treating many infrarenal aortic aneurysms. Infection is one of the most serious complications of this technique, and although percutaneous treatment has been well established for intra-abdominal collections, its use to treat peri-prosthetic fluid collections has not been well determined. In this article we describe a small series of three patients who were treated with percutaneous drainage, with good clinical and imaging responses. Percutaneous drainage is a safe, effective and minimally invasive […]

ABSTRACT Objective: To determine the value of ultrasonography in elbow ligament assessment compared to magnetic resonance imaging. Methods: A prospective single-center study involving 30 volunteers with no elbow joint changes. Two experienced ultrasound specialists evaluated both elbows of each volunteer, resulting in 60 evaluations per physician and totaling up 120 evaluations. Magnetic resonance images were obtained using a 3-Tesla machine and evaluated by two experienced radiologists, totaling up 120 exams. Each examiner assigned subjective, zero-to-5 scores to ligaments imaged, where […]

ABSTRACT Objective To evaluate safety and effectiveness of nodule volume reduction and thyroid function after percutaneous laser ablation treatment in patients with benign nonfunctioning thyroid nodules. Methods Prospective single-center study, from January 2011 to October 2012, which evaluated 30 euthyroid and thyroid antibodies negative patients with benign solitary or dominant nodule with indication of treatment due to compressive symptoms and aesthetic disturbances. The clinical and laboratory (thyroid ultrasound, TSH, FT4, TG, TG-Ab, TPO-Ab and TRAb levels) evaluations were performed before […]

DOI: 10.1590/S1679-45082018RC4254

ABSTRACT The aim of this study were to describe the technique of percutaneous drainage of iliopsoas abscess, and to discuss the benefits of using this minimally-invasive tool. A single center study with retrospective analysis of patients with psoas abscess confirmed by imaging scans, sent to the interventional medicine center and submitted to computed tomography and ultrasound-guided percutaneous drainage, from November 2013 to August 2016. Seven patients underwent percutaneous drainage of psoas abscess in this period. The mean initial drained volume […]

ABSTRACTUltrasound examination of the chest has advanced in recent decades. This imaging modality is currently used to diagnose several pathological conditions and provides qualitative and quantitative information. Acoustic barriers represented by the aerated lungs and the bony framework of the chest generate well-described sonographic artifacts that can be used as diagnostic aids. The normal pleural line and A, B, C, E and Z lines (also known as false B lines) are artifacts with specific characteristics. Lung consolidation and pneumothorax sonographic […]

ABSTRACTObjectiveTo correlate the Thyroid Imaging Reporting and Data System (TI-RADS) and the Bethesda system in reporting cytopathology in 1,000 thyroid nodules.Methods A retrospective study conducted from November 2011 to February 2014 that evaluated 1,000 thyroid nodules of 906 patients who underwent ultrasound exam and fine needle aspiration.Results A significant association was found between the TI-RADS outcome and Bethesda classification (p

High correlation between microbubble contrast-enhanced ultrasound, magnetic resonance and histopathology in the evaluation of hepatocellular carcinoma

DOI: 10.1590/S1679-45082013000400017

OBJECTIVES:To evaluate the efficacy of microbubble contrast ultrasound in diagnosis of hepatocellular carcinoma and to compare its results with those of magnetic resonance and histopathology.METHODS:A total of 29 patients suffering from chronic liver diseases and awaiting liver transplants at Hospital Israelita Albert Einstein were subject to magnetic resonance, microbubble contrast ultrasound, and excision liver biopsies.RESULTS:Excellent agreement between magnetic resonance and microbubble contrast ultrasound was observed in this study. There was moderate agreement between both imaging methods and histopathology results.CONCLUSION:Microbubble contrast […]
