Sentence examples for detectability and quantification from inspiring English sources
Therefore, the impact of PET acquisition duration and attenuation data on artefact occurrence, lesion detectability, and quantification was investigated.
The experimental data allowed us to determine some practical aspects regarding the MDA or the influence of reconstruction parameters on detectability and quantification accuracy.
Additional parameters such as the impact of two iterations were omitted as the study was limited to evaluating the trade-off between detectability and quantification.
While improving the SNR and, therefore, facilitating identification and delineation of sufficiently large low intensity structures, these filters at the same time reduce the spatial resolution of the images, thus deteriorating detectability and quantification accuracy of small lesions.
In this study, we therefore investigated the influence of PET acquisition duration on the quality of both emission as well as attenuation data in whole-body 68Ga-PSMA PET-MRI obtained 1 h after tracer injection and how this affects image artefacts, lesion detectability, and quantification.
Results from this study show that halo artefacts around the kidneys and the urinary bladder, organs with high radiotracer activity, are indeed a relevant issue in 68Ga-PSMA PET-MRI acquired with the clinical Siemens mMR hybrid PET-MRI system, potentially hampering lesion detectability and quantification.
This primer extension assay was then validated in terms of linearity (linear range = 0.5 2.5 nM), detectability (limits of detection and quantification = 0.023 and 0.091 nM, respectively), and precision (total precisions = 8.1% and 3.7% for dATP and dCTP, respectively, n = 9).
The accumulation of [18F]FMISO in bladder starts 10 15 min post-tracer injection (Fig. 3) due to variable urinary excretion and may affect tumour uptake by a phenomenon called spill-in which can affect both lesion detectability [70, 71] and quantification [72].
The impact of reconstruction parameters on quantification accuracy, detectability, and spatial localization of the signal was investigated.
The best choice of PSF reconstruction parameters will be a trade-off between lesion detectability and avoiding PSF artifacts affecting quantification, which should be optimized for the specific task.
Lipid staining and quantification.
