Chest CT Imaging Protocol for Research

Find Similar Protocols

All chest CTs were performed with 128-row spiral CT scanners (Somatom x.Site or Somatom Force, Siemens Medical Systems, Erlangen, Germany). The scans were acquired in a craniocaudal direction during a single-breath-hold either contrast-enhanced or non-enhanced. If contrast-enhanced CT was performed, a 1.0 mL/kg body weight bolus of iopromide 370 mg/mL (Ultravist, Bayer, Leverkusen, Germany) was injected intravenously by a power injector with an acquisition time of 75 s. Table 1 shows further technical details.

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.
