Liu Y. Concurrent FDG avid nasopharyngeal lesion and generalized lymphadenopathy on PET-CT imaging is indicative of lymphoma in patients with HIV infection. AIDS Res Treat. 2012;2012:764291.Liu Y. Concurrent FDG avid nasopharyngeal lesion and gen- eralized lymphadenopathy on PET-CT imaging is ...
Instead, the application of a threshold of four newly emerged, [18F]FDG- avid lesions—with a decreasing cutoff of lesion number as the functional diameter of the lesions increases—can more correctly classify patients with progressive disease. More specifically, PMD is determined as the ...
Then, the PET and CT images uploaded to the LIFEx software, and the lesion with the highest FDG uptake among all lesions was selected. The lesion was manually segmented layer by layer along its edge from the top to the bottom level, with appropriate adjustments made in the coronal and ...
Of these 185 patients, 103 (56%) had concomitant osseous involvement at the site of the BM lesion; 70 (38%) had no osseous involvement; and in 12 cases (6%), correlative imaging of adequate quality was not available for central reading so that osseous involvement was judged “unknown.” ...
Not only U-Net [29] as an image segmen- tation method but also regional CNN (RCNN) and M2Det [30] as object extraction methods, may be useful to localize the lesion. In a study by Yan K et al., MR image segmentation was performed using a deep learning-based technology named the ...
To assess if combined fluorescence- and radio-guided occult lesion localization (hybrid ROLL) is feasible in patients scheduled for surgical resection of non-palpable18F-FDG-avid lesions on PET/CT. Four patients with18F-FDG-avid lesions on follow-up PET/CT that were not palpable during physical...
The volumes of all tumors were measured by outlining the lesion on each image if it was visible. No attempts were made to differentiate the tumors from any related edema. The tumor volumes were contoured and the volumes calculated using the same planning system. To reduce inter-observer ...
The curves are derived from a MM lesion in the os ilium (curve with blue dots) and from the common iliac artery (curve with gold dots) in the respective VOIs. The curves show that both tracers accumulate increasingly in the MM lesions Full size image...
progressive disease is defined as the appearance of new osteolytic lesion(s), ≥ 50% increase from nadir in the sum of the products of the maximal perpendicular diameters of > 1 lesion, or ≥ 50% increase in the longest diameter of a previous lesion > 1 cm in short ...
