Comparative Study
Evaluation of gross tumor size using CT, 18F-FDG PET, integrated 18F-FDG PET/CT and pathological analysis in non-small cell lung cancer.
The correlation of gross tumor sizes between combined 18F-FDG PET/CT images and macroscopic surgical samples has not yet been studied in detail. In the present study, we compared CT, 18F-FDG PET and combined 18F-FDG PET/CT for the delineation of gross tumor volume (GTV) and validated the results through examination of the macroscopic surgical specimen. ⋯ 18F-FDG PET/CT correlates more faithfully with pathological findings than 18F-FDG PET or CT. Integrated 18F-FDG PET/CT is an effective tool to define the target of GTV in radiotherapy.

While computed tomography (CT) scan usage in acute trauma patients is currently part of the standard complete diagnostic workup, little is known regarding the time factors involved when CT scanning is added to the standard workup. An analysis of the current time factors and intervals in a high-volume, streamlined level-1 trauma center can potentially expose points of improvement in the trauma resuscitation phase. ⋯ In a high-volume level-1 trauma center, the complete radiological workup of trauma patients stable enough to undergo CT scanning, is completed in a median of 114 min. Patients that are more severely injured based on ISS were transported faster to CT, resulting in faster diagnostic imaging.
