1.5 t magnetom espree

CT imaging was conducted using a second-generation 128-slice dual-source CT (Somatom Definition Flash, Siemens Healthcare, Erlangen, Germany). Image series (axial, coronal, and sagittal: section thickness 1 mm, increment 0.75 mm) were reconstructed with a dedicated bone kernel. The CT protocols used in the setting of acute trauma in our institution include unenhanced head and cervical spine images and split-bolus contrast enhanced imaging of the lung, abdomen and thoracolumbar spine, adapted as needed.
MR imaging was conducted with a 1.5-T Magnetom Avanto, 1.5- T Magnetom Espree, or 3-T Magnetom Trio system (all from Siemens Healthcare) using similar protocols with a body spine-array coil and fast spin-echo imaging. As per institutional guidelines, T1-weighted, T2-weighted, and T2 turbo inversion recovery magnitude (TIRM) images were obtained in the sagittal plane, and T1-and T2-weighted images were obtained in the axial plane, patient supine. For sagittal imaging, a FOV of 32 cm, matrix of 512 × 256, and slice thickness of 4 mm were used, and for axial images a FOV of 22 cm, matrix of 320 × 320 and slice thickness of 3 mm were used.
The image series were automatically transferred to the picture archiving and communication system (PACS; General Electric Company).

A 1.5-Tesla magnetic resonance scanner (1.5 T MAGNETOM Espree, Siemens, Erlangen, Germany) was used for CMR imaging. Patients were examined in the supine position, and ventricular volumes were evaluated in the scout, long-axis and transaxial planes followed by the short-axis plane. Time–volume curves for left and right ventricular filling, ejection fraction, peak filling rate and stroke volume were derived. Heart chamber volumes were measured during the end-expiratory cycle, and the ejection fraction, peak emptying rate, and filling rate were computed.15 (link) Standard flow measures with phase-contrast velocity mapping were used to evaluate aortic and pulmonary flows.
