Ziel: Patienten mit einem Marfan-Syndrom benötigen eine regelmäßige Bildgebung zur Detektion von Aneurysmen der Aorta ascendens. Ziel dieser Studie war es, die Reproduzierbarkeit von Messungen des Sinus valsalvae mittels Cine-MRT und Echokardiografie an Patienten mit Verdacht auf Marfan-Syndrom zu untersuchen. Material und Methoden: 51 konsekutive Patienten mit Verdacht auf Marfan-Syndrom wurde...

BACKGROUND AND PURPOSE The demonstration of communication between arachnoid cysts (ACs) and the adjacent subarachnoid space is a prerequisite for their proper management. CT cisternography (CTC) is the conventional method for functional evaluation of ACs. The sensitivity of MR imaging to CSF flow has been demonstrated, but reports of the clinical usefulness of MR CSF flow techniques in this app...

Introduction: Time-resolved (CINE) phase contrast (PC) MRI permits the assessment of blood flow within entire 3D vascular structures [1, 2]. The resulting high-dimensional datasets (3 spatial dimensions, 3 velocity directions, and time) require new visualization and quantification methods to derive reliable clinical parameters. In this context, an advanced flow quantification tool was developed...

Cardiac function has traditionally been evaluated using breath-hold cine acquisitions. However, there is a great need for free breathing techniques in patients who have difficulty in holding their breath. Real-time cardiac MRI is a valuable alternative to the traditional breath-hold imaging approach, but the real-time images are often inferior in spatial and temporal resolution. This article pr...

Background. Transthoracic ultrasonography of the heart is valuable in monitoring and treatment of critically ill patients. Speckle tracking ultrasound (STU) has proven valid in estimating left ventricular systolic deformation. The aims of the study were to compare conventional and automated STU and to determine whether left ventricular systolic deformation could be estimated from one single ima...

Sixteen cine magnetic resonance imaging (MRI) studies were performed in 14 patients aged 1 week to 17 years (mean age, 46 months), who had coarctation of the aorta confirmed at angiography or surgery. Conventional echocardiographic-gated MRI was first performed in axial and rotated sagittal views and was used to identify the slice locations for cine MRI. Cine MRI was performed by gradient-recal...

BACKGROUND To predict success of endoscopic third ventriculostomy (ETV) in patients with obstructive hydrocephalus, we evaluated pre- and post- operative phase-contrast cine magnetic resonance images (PC MRI) on cerebrospinal fluid (CSF), cine flow in basal cisterns around the brain stem, and cervical medullar junction (CMJ) retrospectively. METHODS The study involved 102 patients with mean a...
