We also demonstrate the clinical values of synthetic PET in improving lung cancer diagnosis, staging, risk prediction, and prognosis. Taken together, this proof-of-concept study testifies to the feasibility of applying deep learning to obtain high-fidelity PET translated from CT. Graphical abstract ...
as measured for a point source at the center of the scanner, and better than the 1 mm resolution. To obtain high spatial resolution across the FOV, all these four scanners are based on detectors
Sensitivity of small animal scanners that can perform mouse studies and have axial FOVs longer than 100 mm. The sensitivities were estimated using the solid angle coverage, and the sensitivities at the center of the scanners are reported using the published data. Note the need to extend the axi...
While L2 allows easier optimization in diffusion training due to its convergence properties, it is known to produce an averaging effect, which forces the model to predict values closer to the mean of training data [60]. We argue that using only L2 loss can help preserve whole image-level ...
[18F]-FDG PET/MRI) on the decision workflow of epileptic patients with discordant electroclinical and MRI data. A novel mathematical model was introduced for a clinical concordance calculation supporting the classification of our patients by subgroups of clinical decisions. Fifty-nine epileptic patients...
one potential approach is to utilise publicly available protocols for data acquisition and implement data harmonisation methods, such as ComBat [82]. Additionally, it is crucial to closely adhere to the IBSI recommendations [60] regarding image pre-processing steps, feature calculation, and reporting....
The method of 18F-sodium fluoride (NaF) positron emission tomography/computed tomography (PET/CT) of atherosclerosis was introduced 12 years ago. This approach is particularly interesting because it demonstrates microcalcification as an incipient sign of
The sample size calculation is based on the primary endpoint RFS. For the control arm, the estimated RFS is based on sub-group analysis of high-risk PCa patients within trials using MHRT, which ranged between 80.5 and 84% [1,3,5]. Considering differences in applied doses, a different de...
(1), with respect to those in the petroclival region (0.88).68Ga-DOTATOC PET/MRI was characterized by very high SE (0.99) and SP (0.83), which resulted not meaningfully influenced by lesions’ location. Of note, SUV values were lower, although not significantly, in meningiomas missed by...
a metric and a binary variable. The point on the ROC curve with the minimal distance to the point with 100% sensitivity and 100% specificity was defined as the optimum cut-off value. The data for pseudoprogression is described in frequency and percentage, values are given in median and ...
