Chest CT was performed using various scanners: 64-detector rows (Somatom definition, Siemens Medical System, Erlangen, Germany; Discovery CT 750 HD, GE Healthcare, Waukesha, WI, USA) or 128-detector rows (Definition AS+, Siemens Medical System, Erlangen, Germany) for one breath hold. The scans were obtained from the level of the lung apices to the adrenal glands. The scanning parameters included a 130–293 mAs tube current, a 100–140 kV tube voltage, and a variable scan thickness of 2.5–5 mm section thickness, without a specific scan interval. All CT examinations were performed with intravenous contrast material (Iopromide (Ultravist 300), Bayer Schering Pharma AG, Berlin, Germany; ioversol (Optiray 320 mg/mL), Mallinckrodt Pharmaceuticals, Dublin, Ireland).
Optiray 320 mg ml
Manufactured by Mallinckrodt
Sourced in Germany, Ireland
Optiray 320 mg/mL is a radiopaque contrast medium used in diagnostic imaging procedures. It contains the active ingredient ioversol, which helps enhance the visibility of internal structures during imaging examinations.

Patients in Group A underwent imaging with a 64-detector CT unit (Discovery CT 750 HD; GE Healthcare, Waukesha, WI, USA), while those in Group B underwent imaging with a 256-detector CT unit (Revolution CT; GE Healthcare). CT parameters used for imaging in groups A and B are presented in Table 1 . For contrast enhancement, we intravenously administered a nonionic iodinated contrast medium (ioversol [Optiray 320 mg/mL]; Mallinckrodt Pharmaceuticals, Dublin, Ireland; 2 mL/kg body weight) without dilution into the right cubital vein at 3 mL/s and followed this with an immediate 25-mL saline flush at the same injection rate. CT venography was performed from the level of the 12th thoracic vertebra to toes from 4 minutes after initiating contrast injection for all patients. One radiologist recorded the CT dose index (CTDI; mGy) and dose-length product (DLP; mGy × cm) in a picture archiving and communication system. Reconstruction times were recorded by a radiologic technician at each examination.
About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
