Dual-energy computed tomography compared with ultrasound in the diagnosis of gout.
Rheumatology (Oxford)
PUBLISHED: 10-17-2013
Show Abstract
Hide Abstract
Objectives. The aim of our study was to compare dual-energy CT (DECT) with US for the diagnosis of gouty arthritis and to correlate the imaging findings with results from synovial fluid aspiration whenever possible. Methods. We recruited 21 patients (17 male and 4 female) who presented with a clinical suspicion of acute or chronic gout in 37 joints. DECT scans of the hands, wrists, feet, ankles, knees and elbows were performed. For post-processing, a colour-coding gout software protocol was used. US examinations of the same joints were performed. In addition, joint fluid aspiration was performed in a total of 14 joints. Results. DECT images were positive for urate crystal deposits in 25 of 37 joints. US findings were positive in 24 of 37 examined joints. In 12 of 14 joints the synovial fluid aspiration was positive. CT and US findings correlated in 32 of 37 joints (86.5%; ? = 0.698, P < 0.001). CT and synovial fluid results correlated in 12 of 14 joints (85.7%; ? = 0.417, P = 0.119). US and cytology findings correlated in 14 of 14 joints (100%; ? = 1, P < 0.001). Conclusion. DECT and US have comparable sensitivity for the detection of gouty arthritis in a clinical setting. However, DECT results should be interpreted carefully, as there could be some false-negative findings.

Common anatomical variation in patients with idiopathic meralgia paresthetica: a high resolution ultrasound case-control study.
Pain Physician
PUBLISHED: 05-25-2013
Show Abstract
Hide Abstract
Meralgia paresthetica (MP) is a mononeuropathy of the lateral femoral cutaneous nerve (LFCN) characterized by pain, numbness or paresthesia on the anterolateral aspect of the thigh. Though several contributing factors have been identified, the cause of its idiopathic form still remains unclear. Anatomic and clinical studies have demonstrated a variable course for the LFCN and have suggested a contribution to the pathogenesis of MP.

3T MR tomography of the brachial plexus: structural and microstructural evaluation.
Eur J Radiol
PUBLISHED: 03-07-2011
Show Abstract
Hide Abstract
Magnetic resonance (MR) neurography comprises an evolving group of techniques with the potential to allow optimal noninvasive evaluation of many abnormalities of the brachial plexus. MR neurography is clinically useful in the evaluation of suspected brachial plexus traumatic injuries, intrinsic and extrinsic tumors, and post-radiogenic inflammation, and can be particularly beneficial in pediatric patients with obstetric trauma to the brachial plexus. The most common MR neurographic techniques for displaying the brachial plexus can be divided into two categories: structural MR neurography; and microstructural MR neurography. Structural MR neurography uses mainly the STIR sequence to image the nerves of the brachial plexus, can be performed in 2D or 3D mode, and the 2D sequence can be repeated in different planes. Microstructural MR neurography depends on the diffusion tensor imaging that provides quantitative information about the degree and direction of water diffusion within the nerves of the brachial plexus, as well as on tractography to visualize the white matter tracts and to characterize their integrity. The successful evaluation of the brachial plexus requires the implementation of appropriate techniques and familiarity with the pathologies that might involve the brachial plexus.

Peripheral nerves: ultrasound-guided interventional procedures.
Semin Musculoskelet Radiol
PUBLISHED: 11-11-2010
Show Abstract
Hide Abstract
Specific ultrasound (US)-guided interventional procedures on peripheral nerves are reviewed in this article including regional anesthesia, biopsy of neural lesions, and some injection therapies. For these procedures, US is the best modality to provide a safe imaging guidance because of its excellent spatial resolution and real-time capabilities. With US guidance, the radiologist can visualize the needle tip continuously and ensure that the needle is placed precisely in the desired location, avoiding the risk of inadvertent nerve damage. Practical tips and tricks for US-guided needle placement, biopsy of neural lesions, and US-guided therapy are reviewed in this article. The use of US-guided injections in specific clinical settings, such as the percutaneous treatment of carpal tunnel syndrome, Mortons and saphenous neuromas, painful stump neuromas, piriformis syndrome, and meralgia paresthetica are also illustrated here. US allows the clinician to inject drugs with little or no patient discomfort.

Tumour ablation: technical aspects.
Cancer Imaging
PUBLISHED: 12-08-2009
Show Abstract
Hide Abstract
Image-guided percutaneous radiofrequency ablation (RFA) is a minimally invasive, relatively low-risk procedure for tumour treatment. Local recurrence and survival rates depend on the rate of complete ablation of the entire tumour including a sufficient margin of surrounding healthy tissue. Currently a variety of different RFA devices are available. The interventionalist must be able to predict the configuration and extent of the resulting ablation necrosis. Accurate planning and execution of RFA according to the size and geometry of the tumour is essential. In order to minimize complications, individualized treatment strategies may be necessary for tumours close to vital structures. This review examines the state-of-the art of different device technologies, approaches, and treatment strategies for percutaneous RFA of liver tumours.

What is Visualize?

JoVE Visualize is a tool created to match the last 5 years of PubMed publications to methods in JoVE's video library.

How does it work?

We use abstracts found on PubMed and match them to JoVE videos to create a list of 10 to 30 related methods videos.

Video X seems to be unrelated to Abstract Y...

In developing our video relationships, we compare around 5 million PubMed articles to our library of over 4,500 methods videos. In some cases the language used in the PubMed abstracts makes matching that content to a JoVE video difficult. In other cases, there happens not to be any content in our video library that is relevant to the topic of a given abstract. In these cases, our algorithms are trying their best to display videos with relevant content, which can sometimes result in matched videos with only a slight relation.
