Gadofosveset-Trinatrium-Enhanced MR Angiography and MR Venography in the Diagnosis of Venous Thromboembolic Disease: A Single-Center Cohort Study.

Background: The aim of this single-center combined prospective/retrospective cohort study was to analyze Gadolinium (Gd)-enhanced MRA (magnetic resonance angiography) and MRV (MR venography) for the diagnosis of pulmonary artery embolism and deep venous thrombosis. The gold standard methods result in major exposure to radiation and a high amount of nephrotoxic iodinated contrast media. This is the first larger contrast-enhanced MR imaging study of acute and chronic venous thromboembolic disease of various stages.

Cardiogenic shock and tumor resection due to cardiac synovial sarcoma: a case report.

Background: Cardiac synovial sarcoma of the heart is a rare, aggressive mesenchymal tumor with poor prognosis, since complete resection is seldom feasible.

Case Presentation: A 23-year-old man was referred in cardiogenic shock. Emergency computed tomography (CT) revealed a large tumor with obstruction of the right atrium (RA) and prolapse into the right ventricle (RV).

[Popliteal Artery Entrapment Syndrome: Three Unusual Cases with Different Courses to Diagnosis].

Introduction: Popliteal artery entrapment syndrome (PAES) is a pathology characterised by anatomical anomalies of the relative position of the popliteal artery (PA) to the medial head of the gastrocnemius muscle (MHGM), resulting in mechanical compression causing damage to and occlusion of the artery.

Patients: From 2012 to 2018, we operated on 3 male patients aged 17 to 48 years, who presented with PAES in our department. The first and oldest patient had previously undergone femoro-popliteal bypass surgery in 2003 when aged 23, with the underlying diagnosis of "posttraumatic PAOD II b" followed by several reoperations.

Gadobutrol in Renally Impaired Patients: Results of the GRIP Study.

Objective: The aim of this study was to assess the potential risk of gadobutrol-enhanced magnetic resonance imaging (MRI) in patients with moderate to severe renal impairment for the development of nephrogenic systemic fibrosis (NSF).

Materials And Methods: We performed a prospective, international, multicenter, open-label study in 55 centers. Patients with moderate to severe renal impairment scheduled for any gadobutrol-enhanced MRI were included.

Gadobenate dimeglumine and gadofosveset trisodium for MR angiography of the renal arteries: Multicenter intraindividual crossover comparison.

Objective: This prospective multicenter intraindividual crossover study was designed to compare gadobenate dimeglumine and gadofosveset trisodium at approved doses with respect to the image quality and diagnostic performance of contrast-enhanced MR angiography (CE-MRA) in the detection of clinically relevant renal artery stenosis.

Subjects And Methods: Thirty-nine subjects (17 men, 22 women; age range, 30-86 years; mean 62 +/- 13.3 [SD] years) with known or suspected renovascular disease underwent a first CE-MRA examination with 0.

Clinical, radiological, and pathological findings in four children with gastrointestinal stromal tumors of the stomach.

The incidence of gastrointestinal stromal tumors (GISTs) in children is exceptionally low. However, during the last decade these tumors attracted increasing attention, because they were found to express the cell surface transmembrane receptor kit (CD117) that has tyrosine kinase activity. This tyrosine kinase can be semi-selectively inhibited by signal transduction inhibitors such as imatinib mesylate (Glivec), which is a competitive inhibitor of c-kit, c-abl, platelet-derived growth factor receptor-alpha (PDGFR-alpha) and PDGFR-beta, and abl-related gene (arg).

Efficacy and safety of gadodiamide (Gd-DTPA-BMA) in renal 3D-magnetic resonance angiography (MRA): a phase II study.

Purpose: To determine the most efficacious dose of gadodiamide for three-dimensional (3D) contrast-enhanced (CE) magnetic resonance angiography (MRA) of the renal arteries on a patient level based on the sensitivity in detecting the main hemodynamically relevant (> or =50% or occlusion) renal artery stenosis (RAS) using intra-arterial digital subtraction angiography (IA DSA) as the gold standard.

Materials And Methods: This prospective, randomized, double-blind, parallel-group, multicenter study included 273 patients referred to IA DSA for suspected RAS. Patients underwent 3D CE MRA after injection of 0.

Three-dimensional gadolinium-enhanced magnetic resonance angiography used as a "one-stop shop'' imaging procedure for venous thromboembolism: a pilot study.

Pulmonary embolism and deep venous thrombosis are individual manifestations of a single entity, venous thromboembolic disease. This study aimed to assess the feasibility of 3-dimensional gadolinium-enhanced magnetic resonance angiography used as an "one-stop shop'' imaging procedure visualizing both the pulmonary arteries and the deep lower venous system within a single investigation. The inclusion criterion was a proven or excluded venous thromboembolism.

Congenital familial vascular anomalies: a study of patients with an anomalous inferior vena cava, and of their first-degree relatives.

With magnetic resonance angiography and computed tomography, congenital anomalies of the inferior vena cava are diagnosed more frequently than they used to be. Accessory renal arteries identified by magnetic resonance angiography in a patient with an anomalous inferior vena cava indicated a combination of arterial and venous abnormalities. The study was initiated to screen consecutive patients with an anomalous inferior vena cava for concomitant abdominal and pelvic arterial abnormalities, and their first-degree relatives for congenital vascular anomalies.

Value of a blood pool contrast agent in MR venography of the lower extremities and pelvis: preliminary results in 12 patients.

The purpose of this study was to determine the value of a blood-pool contrast media (NC100150, Nycomed Imaging (now Amersham Health) Oslo, Norway) for evaluation of venous thrombosis of the deep veins of the pelvis and lower extremities. Twelve patients were prospectively evaluated with conventional X-ray venography (XRV) and MR venography (MRV) after injection of NC100150 (2 ml/kg body weight). The source images and 3D maximum intensity projection (MIP) were viewed on an independent workstation.

Gadobutrol-enhanced moving-table magnetic resonance angiography in patients with peripheral vascular disease: a prospective, multi-centre blinded comparison with digital subtraction angiography.

The purpose of this study was to compare moving-table three-dimensional contrast-enhanced magnetic resonance angiography (CE MRA), using 1.0-mol gadobutrol, with intra-arterial digital subtraction angiography (i.a.

Anomalies of the inferior vena cava in patients with iliac venous thrombosis.

Background: Cases of deep venous thrombosis in the lower extremities triggered by abnormalities of the vena cava have been reported.

Objective: To describe anomalies of the inferior vena cava in patients with deep venous thrombosis.

Design: Prospective, consecutive case series.
