Iomeprol iomeron 300

All examinations were performed using a 16-detector-row CT scanner (Sensation 16; Siemens, Erlangen, Germany) that was located in the emergency department. The CT scans were obtained with end-inspiration state, as far as possible, in a supine position. Chest CT scans were performed from the thoracic inlet to the upper abdomen. CT examination was obtained with LDCT without intravenous contrast agent and standard dose CT (SDCT) after intravenous injection of nonionic contrast media (2.5 mL/s, 100 mL Iomeprol—Iomeron 300; Bracco, Milan, Italy) using a power injector. The parameters of LDCT scans were as follows: 0.75 mm-collimation; pitch, 1.0; reference effective tube current time product of 40 mAs with automatic tube current modulation (ATCM); tube voltage of 100 kV (BMI<25) or 120 kV (BMI≥25). The parameters of SDCT scans were as follows: 0.75 mm-collimation; pitch, 1.0; reference effective tube current time product of 180 mAs with ATCM; tube voltage of 120 kV. Coronal, sagittal multi planar reformatted images were reconstructed in both LDCT and SDCT with 3-mm slice thickness without gap. All CT scans were reconstructed using a soft filter kernel. Vendor providing CT dose index volume (CTDIvol) and dose-length product (DLP) were recorded and CT radiation dose descriptor for LDCT and SDCT.
