Second, the thoughtful implementation of FET-PET/CT, in addition to MRI, may positively influence the accuracy, and thus, the quality of target delineation, because one receives useful information regarding the biologic activity of the lesions.
Occasionally, after checking the VOIs on the PET images, the regions were changed so that FDG-positive areas of tumors that were SPECT-negative were included in the delineation because FDG-PET and SPECT images show different aspects of the pathophysiology.
I felt like there needed to be a delineation because I already felt it.
Major white matter tracts helped in this delineation because of their confluent color.
Because of the inherent uncertainty associated with fracture delineation, and because of the irregular nature of unstable dense plumes, deterministic prediction of dense-plume migration pathways and travel times in fractured geologic media will be subject to considerable uncertainty.
But even that nostrum collides with British electoral practice: Because of the delineation of electoral boundaries, the party winning the most votes, as in the United States, does not necessarily win the most legislative seats.
The game was refused classification because "there is insufficient delineation between the 'fictional drugs' available in game and real-world proscribed drugs".
Based on our clinical experience in routine evaluation, b30f was used instead of b20f because of a better delineation of the coronary arteries and atherosclerotic lesions.
Once a fluorescence signal was detected, it was easy to excise the SN because of the clear delineation of the fluorescence-labelled lymph nodes and the high target-to-background ratio (Fig. 4).
Because IMRT requires highly accurate delineation of the tumour and the normal organs and structures, immobilization of the patient is critical.
