Somatom sensation open ct system

This medical imaging investigation was approved by the Ethics Committee of the Chinese PLA General Hospital. Requirements for informed consent were waived due to the retrospective study design. Furthermore, the patients' data were made anonymous.
In total, 204 patients with normal femoral morphologies who underwent lower-extremity CT angiography between December 2009 and December 2012 were included in this study. Some patients were included in our previous study [25 (link)]. After evaluation by two senior orthopaedic surgeons (Li-hai Zhang and Xiu-yun Su) in an independent manner, patients with evidence of lower-extremity trauma, acetabular dysplasia, amputation, avascular necrosis of the femoral head or intervention, and femoral or pelvic implants were excluded. The demographic data, including age, gender, height, and CT data, were collected. All CT scans were performed by the Somatom sensation open CT System (Siemens AG, Erlangen, Germany) with slice thicknesses of 1.2 mm.

This study involved medical imaging investigations and was approved by the ethics committee of the Chinese PLA General Hospital. After obtaining informed patient consent, data on the demographic characteristics of 25 patients with unilateral pelvic fractures who were admitted to the Department of Orthopaedics and Trauma at the Chinese PLA General Hospital between March 2014 and March 2015 was prospectively collected.
All 25 patients met our inclusion criteria: (1) a relative stable general condition, (2) had unilateral unstable pelvic fractures suitable for closed reduction and minimally invasive fixation, (3) they were willing to participate in the study and 8- to 12-month follow-up. Patients with severe associated injuries that were treated in the same operation as the pelvic fractures and patients that were unsuitable for closed reduction and minimally invasive fixation were excluded.
We also collected preoperative CT images in Digital Imaging and Communications in Medicine (DICOM) format. All CT scans were performed using a Somatom Sensation open CT system (Siemens AG, Erlangen, Germany) with a slice thickness of 1.5 mm. The CT data (DICOM) were imported into Amira software (Visage Imaging GmbH, Berlin, Germany) to reconstruct and simulate the standard inlet, outlet, and AP views of the pelvis.

The study was a medical imaging investigation approved by the Ethics Committee of Chinese PLA General Hospital. Due to its retrospective nature and the anonymous patient data, a waiver of patients’ informed consent was granted. Data were obtained on patients with pelvic fractures who were admitted to the Department of Orthopaedics and Trauma at the Chinese PLA General Hospital between March 2012 and March 2013.
A review of plain radiographs revealed that 25 patients with unilateral pelvis injury and dislocation had minimal or no displacement of the contralateral segment. We collected the CT Digital-Imaging-and-Communications-in-Medicine (DICOM) data. All CT scans were performed with a Somatom sensation open CT System (Siemens AG, Erlangen, Germany) with slice thicknesses of 1.5 mm.
