A prospective study was performed to evaluate the efficacy of a gadolinium-chelate-enhanced MR angiography (MRA) using a coronal acquisition in the preoperative assessment of aneurysms of the abdominal aorta (AAA). Twenty patients with AAA were explored with MR using a two-dimensional (2D) time-of-flight MRA technique with a coronal acquisition, before and(More)
PURPOSE To compare transesophageal echocardiography (TEE) and magnetic resonance (MR) imaging in the diagnosis of dissection of the thoracic aorta. MATERIALS AND METHODS Thirty-one consecutive patients with clinically suspected aortic dissection and 10 postoperative patients underwent transesophageal color Doppler echocardiography and MR imaging. Imaging(More)
PURPOSE To evaluate the combined performance of two time-of-flight methods in imaging the pulmonary arteries. MATERIALS AND METHODS This study was prospectively conducted in 28 patients suspected for pulmonary embolism (PE). Sixteen patients were free of pulmonary vascular disease, and 12 had pulmonary vascular disease as demonstrated by pulmonary(More)
The purpose of this study was to evaluate the diagnostic value of MRA in determining vascular involvement in bronchogenic carcinoma with Pancoast syndrome. Six patients with Pancoast syndrome were investigated preoperatively by means of MRA. Following standard spin-echo MR imaging in the axial and coronal planes, two successive two-dimensional (2D)(More)
We report an unusual case of pulmonary lymphangioleiomyomatosis in a menopaused woman who had been taking estrogen hormone replacement therapy for several years. The characteristic feature of this uncommon disease is a proliferation of non-tumoral abnormal smooth muscle cells within the alveolar walls, and around the bronchi, lymph nodes and blood vessels.(More)
In the last few years there has been much interest in the delivery of software-as-a-service. The concept of the remote delivery of software by Application Service Providers (ASPs) has captured the imagination of many academics, practitioners and technology analysts. Yet analyst predictions and expectations with respect to the growth of this new e-business(More)
Application service provision, which consists of deploying, managing, and remotely hosting software applications through centrally located servers, is emerging as a new form of application outsourcing that is attractive to many sectors. Partnering in this context has gained major importance among practitioners and researchers. Although this article(More)
PURPOSE To evaluate magnetic resonance venography (MRV) in the detection of cervical/mediastinal venous thrombosis (CMVT). METHODS MR venograms were performed in 20 patients suspected for CMVT. 2D-TOF MR venography was used for all studies. MR and conventional venographic/surgical data were collected prospectively and analyzed in a blinded manner(More)
The purpose of this study was to compare the performance of 2D vs. 3D time-of-flight (TOF) methods in imaging the normal pulmonary arteries with commercially available 1.0 T equipment. The study was conducted in 20 volunteers and 7 patients with suspected pulmonary embolism (PE). To reduce artifacts caused by cardiac and respiratory motion, MR images were(More)
