Subsegmental Pulmonary Emboli: Improved Detection with Thin-Collimation Multi–Detector Row Spiral CT

Abstract

For the diagnosis of subsegmental pulmonary emboli at multi-detector row CT, the use of 1-mm section widths results in substantially higher detection rates and greater agreement between different readers than the use of thicker sections.

Right Ventricular Enlargement on Chest Computed Tomography

“…Standard contrast-enhanced PE protocols 7 were performed with a 4-slice multidetector-row CT scanner (VolumeZoom, Siemens Medical Solutions) with acquisition of 1.25-mm-thick sections of the entire chest. All CT studies were available in standard Digital Imaging and Communications in Medicine (DICOM) format and were analyzed off-line with the use of a stand-alone image processing workstation (Leonardo, Siemens).…”

Right Ventricular Enlargement on Chest Computed Tomography

“…The diagnosis of PE was confirmed in the presence of at least one filling defect in the pulmonary artery tree, including the subsegmental level. 20 All CT studies were available in standard Digital Imaging and Communications in Medicine (DICOM) format and were analyzed off-line with the use of a stand-alone image processing workstation (Leonardo, Siemens).…”
