64 multidetector row ct scanner

Pretreatment chest CT angiogram (CTA) was routinely performed in all patients
presenting with hemoptysis for localization of active hemorrhage and to see the
disease progression using a 64 multidetector row CT scanner (Siemens). A chest
CT without intravenous contrast was performed within 24 h after DEB-BACE to
assess bead deposition.

CT images were obtained from a 64-multi-detector-row CT scanner (Siemens AG, Wittelsbacherplatz 2, Muenchen, Germany) using a supine position. We used the following parameters for CT images: a gantry rotation speed of 1.00 s/rotation, 0.625 mm collimation width ×12 detectors, a CT pitch factor of 0.90, and a field of view of 25 to 30 cm. The CT images were saved as Digital Imaging and Communications in Medicine (DICOM) format, which were processed by MIMICS software (Materialise, Leuven, Belgium) to create 3D knee model. The created knee models were imported to the Rhinoceros 3D modeling software (Rhino 7, Robert McNeel and Associates for Windows, Washington DC, USA) to simulate the PCL reconstruction and proceed the measurement.

The CTU images, including the unenhanced, arterial, venous, and excretory phases, were obtained by a 64 multidetector row CT scanner (Siemens, Germany) with 1-mm step intervals. The scan delay times for the arterial, venous, and excretory phases were 25, 60, and 600-900 s, respectively, after intravenous injection of contrast material. Patients were advised to hold their breath in inspiration during the process.
