Myocardial perfusion in the arterioles and capillaries within the LV myocardium was modeled as flow through a porous material due to the prohibitive computational cost of resolving discrete microvascular blood vessels49,50,51,52,53,54. Flow through porous materials is described by Darcy’s Law, and...
(P<0.001 for all).Conclusion:Optimizing the length during CT scanning can effectively reduce the intraoperative radiation dose and reduce the operation time compared with conventional plan;low-dose and optimized length CT scan can further reduce the total radiation dose compared with optimized length ...
Lymphatic spread determines treatment decisions in prostate cancer (PCa) patients. 68Ga-PSMA-PET/CT can be performed, although cost remains high and availability is limited. Therefore, computed tomography (CT) continues to be the most used modality for P
However, more systematic, well-designed prospective studies in defined patient populations are needed to clarify the controversies, including indications and cost effectiveness, scan parameters, and quantification. 展开 关键词:PET PET/CT FDG infection fever of unkown origin bacteraemia CNS ...
In three of six studies, scan coverage was reported to include the skull (Arrangoiz 2012; Kang 2011; Maubec 2007), but the detection of brain metastases was not separately documented. Re‐staging Three studies recruited participants undergoing imaging for re‐staging of disease following a clinic...

This can be attributed to the imaging timeline, where the extended period until the capture of the MRI scan allowed it to evolve lesions and become more pronounced, resulting in larger observed lesion volumes. Also, one critical aspect of the AISD dataset is the availability of test samples, ...
Given the small PE targets relative to the input volume, PENet takes in a sliding window of 24 slices at a time instead of the entire volumetric CT scan. Using this sliding window approach increases the proportion of the target PE relative to the input which ultimately escalates the model op...
