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 ...
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...
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

preventing delay of treatment in a cost-effective manner [94]. In a prospective study to evaluate the role of 2-[18F]FDG PET/CT in the initial staging of 142 patients with ≥ T2 BC, when compared with conventional imaging modalities (mammogram and/or breast US, bone scan, abdominal ...
CT scan axial slice showing my spine (on left), then scapula with fractured coracoid process (“Bad”) and displaced, fractured greater tubercle of humerus on right side (“V bad”). So, that explains most of the pain I was in.
(326/1337). During training, all CTs for a given patient under conditions described above were included. For testing evaluation, one scan series per patient was considered. In conditions where patients underwent multiple CT scans, the initial positive CT with RT-PCR confirmed disease were used. ...
