[This corrects the article DOI: 10.1371/journal.pmed.1002220.].

A preliminary study of skin ultrasound in diffuse cutaneous systemic sclerosis: Does skin echogenicity matter?

To evaluate the usefulness of skin ultrasound and acoustic radiation force impulse (ARFI) quantification in diffuse cutaneous systemic sclerosis (dcSSc).

FDG PET diagnosis of primary intracranial lymphoma: radiology-pathology correlation.

Author Response: Quantitative Retinal Optical Coherence Tomography Angiography in Patients With Diabetes Without Diabetic Retinopathy.

White Paper: Curriculum in Interventional Radiology.

Purpose Scope and clinical importance of interventional radiology markedly evolved over the last decades. Consequently it was acknowledged as independent subspecialty by the "European Union of Medical Specialists" (UEMS). Based on radiological imaging techniques Interventional Radiology is an integral part of Radiology. Materials und Methods In 2009 the German Society for Interventional Radiol...

Comparisons among MRI signs, apparent diffusion coefficient, and fractional anisotropy in dogs with a solitary intracranial meningioma or histiocytic sarcoma.

Although MRI has become widely used in small animal practice, little is known about the validity of advanced MRI techniques such as diffusion-weighted imaging and diffusion tensor imaging. The aim of this retrospective analytical observational study was to investigate the characteristics of diffusion parameters, that is the apparent diffusion coefficient and fractional anisotropy, in dogs with a s...

Further characterization of computed tomographic and clinical features for staging and prognosis of idiopathic pulmonary fibrosis in West Highland white terriers.

Idiopathic pulmonary fibrosis is an interstitial lung disease of unknown etiology resulting in progressive interstitial fibrosis, with a known predilection in West Highland white terriers. In humans, computed tomography (CT) is a standard method for providing diagnostic and prognostic information, and plays a major role in the idiopathic pulmonary fibrosis staging process. Objectives of this retro...

Endoscopic Ultrasound-guided Biliary Drainage.

The therapeutic role of endoscopic ultrasound (EUS) has continued to evolve in recent years. EUS-guided biliary drainage (EUS-BD) can be performed as an effective alternative to percutaneous drainage or surgical options when conventional Endoscopic retrograde cholangiopancreatography fails or is not possible. Depending on the access and exit routes of the stent, multiple approaches to EUS-BD have ...

Vertebrobasilar system computed tomographic angiography in central vertigo.

The incidence of vertigo in the population is 20% to 30% and one-fourth of the cases are related to central causes. The aim of this study was to evaluate computed tomography angiography (CTA) findings of the vertebrobasilar system in central vertigo without stroke.CTA and magnetic resonance images of patients with vertigo were retrospectively evaluated. One hundred twenty-nine patients suspected o...

Clinical significance of interval changes in breast lesions initially categorized as probably benign on breast ultrasound.

The aims of this study were to determine the malignancy rate of probably benign lesions that show an interval change on follow-up ultrasound and to evaluate the differences seen on imaging between benign and malignant lesions initially categorized as probably benign but with interval change on follow-up breast ultrasound.We retrospectively reviewed 11,323 lesions from ultrasound-guided core-biopsi...

Improved risk stratification with computed tomographic coronary angiography in patients with suspected coronary artery disease.

Coronary revascularization vs. medical therapy following coronary-computed tomographic angiography in patients with low-, intermediate- and high-risk coronary artery disease: results from the CONFIRM long-term registry.

To identify the effect of early revascularization on 5-year survival in patients with CAD diagnosed by coronary-computed tomographic angiography (CCTA).

Preoperative Use of CT Angiography in Infants With Coarctation of the Aorta.

Computed tomographic angiography (CTA) and echocardiography (echo) are used preoperatively in coarctation of the aorta to define arch hypoplasia and great vessel branching. We sought to determine differences in quantitative measurements, as well as surgical utility, between modalities.

American College of Radiology Contrast Enhanced Ultrasound Liver Imaging Reporting and Data System (CEUS LI-RADS) for the diagnosis of Hepatocellular Carcinoma: a pictorial essay.

Endoscopic ultrasound-guided hemostasis of rectal varices.

Relationship between low tube voltage (70 kV) and the iodine delivery rate (IDR) in CT angiography: An experimental in-vivo study.

Very short acquisition times and the use of low-kV protocols in CTA demand modifications in the contrast media (CM) injection regimen. The aim of this study was to optimize the use of CM delivery parameters in thoraco-abdominal CTA in a porcine model.

Physiologic Reduction of Hepatic Venous Blood Flow by the Valsalva Maneuver Decreases Liver Stiffness.

Liver stiffness increases after intake of food or water, suggesting that hepatic venous blood flow affects the results of elastographic measurements. This study investigated the correlation between in vivo liver stiffness and hepatic blood flow using the Valsalva maneuver for reducing intrahepatic venous blood flow.

Derivation of a Performance Checklist for Ultrasound-Guided Arthrocentesis Using the Modified Delphi Method.

Arthrocentesis is an important skill for physicians in multiple specialties. Recent studies indicate a superior safety and performance profile for this procedure using ultrasound guidance for needle placement, and improving quality of care requires a valid measurement of competency using this modality.

A successful model to learn and implement ultrasound-guided venous catheterization in apheresis.

Apheresis treatments can be performed with peripheral venous catheters (PVC), although central venous catheters (CVC) are inserted when PVCs fail or patient with history of difficult vascular access prior to the apheresis. Ultrasound guidance for PVC has shown promising results in other settings.

Unrecognized coronary vasospasm in patients referred for percutaneous coronary intervention: Intracoronary nitroglycerin, the forgotten stepchild of cardiovascular guidelines.

The goal of this study was to demonstrate the importance of intracoronary nitroglycerin (IC NTG) administration during diagnostic coronary angiography and prior to percutaneous coronary intervention (PCI).

New horizons in the imaging of perianal Crohn's disease: transperineal ultrasonography.

Perianal disease, most commonly manifest as fistula or abscess formation, affects up to 40% of patients with Crohn's disease. Perianal Crohn's disease is disabling, associated with poor outcomes, and represents a therapeutic challenge for physicians. Correct diagnosis and classification of perianal disease is the first crucial step for appropriate multidisciplinary management. Areas covered: A lit...

Exercise Combined With Ultrasound Attenuates Neuropathic Pain in Rats Associated With Downregulation of IL-6 and TNF-α, but With Upregulation of IL-10.

Although there are several evidences that suggest efficacies of therapeutic ultrasound (TU) or treadmill exercise (TE) to alleviate nerve injury-associated pain, molecular mechanisms are less clear. We aimed to investigate the impact of TU and/or TE on neuropathic pain induced by chronic constriction injury (CCI) of the sciatic nerve and their roles of proinflammatory and anti-inflammatory cytokin...

Evaluation of a protocol for same-day discharge after radial lounge monitoring in a southern Swiss referral percutaneous coronary intervention centre.

The aim of the study was to retrospectively evaluate safety and patient satisfaction of same-day discharge after elective radial coronary angiography/percutaneous coronary intervention (PCI) after the implementation of a radial lounge facility.

Evaluation of Lung Function and Clinical Features of the Ultrasound-Guided Stellate Ganglion Block With 2 Different Concentrations of a Local Anesthetic: A Randomized Controlled Trial.

One possible complication of stellate ganglion block (SGB) is respiratory compromise. No study has yet addressed the comparison of its effect on lung function and clinical features, including Horner's syndrome, changes in temperature, sensory and motor functions, and adverse events of lower versus higher concentrations (LC and HC, respectively) of local anesthetics in an ultrasound-guided SGB.
