There was no statistically significant difference in delineation of joints between FD and RD CZT data as the latter identified 383 joints.
A limitation of [18F] 2-fluoro-2-deoxy-d-glucose positron emission tomography (FDGPET) in radiation planning for Hodgkin lymphoma (HL) is significant variability in delineation of tumor volume.
In the decades before the Method taught us to appreciate the (apparently) spontaneous expression of an inner reality, screen acting, particularly in the silent era, was more concerned with the clean, clear delineation of significant surfaces -- a repertory of gestures and facial expressions with agreed-upon meanings.
In this study, porphyry Cu Mo deposits in the Gobi desert, a covered geographical landscape of Eastern Tianshan, China, are taken as an example to illustrate delineation of significant geochemical anomalies in covered area.
Respiratory motion causes significant uncertainties in tumor delineation, radiotherapy (RT) dose calculations, and delivery, particularly in the case of thoracic tumors (e.g., lung, liver) [ 1].
Indeed, the therapeutic implications of these findings support the delineation of significant molecular pathways, such as PIK3CA/mTOR and MAPK cascades for subsequent targeted therapies within specific populations.
A study of 50 patients with non-small cell lung cancer showed significant improvements in tumour delineation with 3 tumours correctly upstaged to T4 following contrast enhancement.
Exclusion criteria included previous thoracic surgery, previous radiation treatment, clinically significant pleural effusion limiting delineation of the total extent of the primary tumor, lobar atelectasis, and an inability to breathe in a reproducible manner (breath variability was more than 5%).
In a separate study, Persson et al. found that 4DCT artifacts caused significant uncertainties in the delineation of the gross tumor volume (GTV) in 16 out of 19 patients [ 7].
Our data indicate that after disease diagnosis there are no significant changes affecting the delineation of B cell subsets in peripheral blood, thus illustrating the potential limitation of similar immunophenotyping studies in humans to robustly identify small phenotypical differences.
