Virtual Non-Contrast CT Using Dual-Energy Spectral CT: Feasibility of Coronary Artery Calcium Scoring.
OBJECTIVE To evaluate the feasibility of coronary artery calcium scoring based on three virtual noncontrast-enhanced (VNC) images derived from single-source spectral dual-energy CT (DECT) as compared with true noncontrast-enhanced (TNC) images. MATERIALS AND METHODS This prospective study was conducted with the approval of our Institutional Review Board. Ninety-seven patients underwent noncon...
متن کاملAutomatic Coronary Calcium Scoring Using Native and Contrasted CT Acquisitions
The evaluation of coronary calcium is a standard procedure in clinical workflows for the diagnosis of patients presenting with suspected coronary artery disease. Based on a native cardiac CT scan, the coronary calcium present in each of the three main coronary arteries is determined. With most clinically available tools, the physician has to manually assign calcium clusters (voxels above 130HU)...
متن کاملDual Energy CT Angiography of Peripheral Arterial Disease: Feasibility of Using Lower Contrast Medium Volume
OBJECTIVE One of the main drawbacks associated with Dual Energy Computed Tomography Angiography (DECTA) is the risk of developing contrast medium-induced nephropathy (CIN). The aim of the present study was firstly, to design an optimal CT imaging protocol by determining the feasibility of using a reduced contrast medium volume in peripheral arterial DECTA, and secondly, to compare the results w...

متن کاملVirtual Non-contrast CT with Spectral CT as an Alternative to Unenhanced CT in Assessment of Gastric Cancer
Gastric cancer accounts for approximately 8% of new cancers worldwide (Jemal et al., 2011). Early diagnosis and accurate preoperative staging are critical for improving outcomes, and this includes the identification of the tumor location, depth of invasion, lymph node status, and the presence of metastasis (Monig et al., 2002; Chen et al., 2007; Makino et al., 2011). Current methods for the det...
