Lesion-to-background SUV ratios served as quantitative metrics of conspicuity. Additionally, two blinded readers evaluated the relative conspicuity of FFBLs on PET images derived from MRI-based AC versus CT-based AC. Visibility of an anatomic correlate for FFBLs on the corresponding CT and MR ...
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...
In the end, a total of 32 of the original 87 individual 18F-FDG-avid lesions identified on the preoperative 18F-FDG PET/CT images were considered as the final 18F-FDG-avid lesion data set for the current retrospective data analysis comparing the preoperative and postoperative 18F-FDG PET/CT ...
FDG-PET/CT scans showing at least 1 FDG-avid lesion localized to an area that did not correspond to physiologic biodistribution of FDG and that did not suggest other pathology than infection were considered positive for an infection focus. Sensitivity and specificity were calculated based on the r...
与常规CT和MRI影像学检查相比, 68Ga-1,4,7,10-四氮杂环十二烷-1,4,7,10-四乙酸(DOTA)-生长抑素类似物(SSA) PET/CT在神经内分泌肿瘤(NEN)的诊断中具有较高的灵敏度和特异度,同时,在疗效评价和预后评估等方面也有重要的指导价值。 18F-氟脱氧葡萄糖(FDG)PET/CT虽然在NEN的诊断中未被常规推荐,但其在良...

For all 18F-FDG-avid lesions, standardised uptake values (SUVs) were also calculated. After 3 weeks, the same exercise was carried out using 18F-FDG PET/CT images, where CT and fused volume data were made available to observers. The degree of interobserver agreement was measured in both ...
A large sclerotic FDG-avid vertebral metastasis is identified on CT (arrow) as well as in the corresponding PET image. The reduced signal intensity on same-level HASTE images (D) makes the lesion visible on the MR image as well. Full size image Figure 3 Axial CT (A), axial PET from ...
The other possible FDG-avid malignant lesion is leukemia such as extramedullary AML extending to the myocardium and pericardium, which used to be a clinically undetectable extramedullary lesion [122]. The value of FDG-PET/CT is its ability to differentiate between benign and malignant tumors and ...
