Consequently, chest high-resolution computed tomography (HRCT) demands are increasing, regarding patients' screening, initial evaluation and follow up. This study aims to evaluate the detection accuracy of ultra-low-dose chest CT in comparison with the routine low-dose chest CT to reduce the ...
High resolution chest Brain perfusion (if performed at the institution) Protocol Naming The primary focus should be on consistent names across the enterprise.22 A facility should consider naming CT protocols in a manner consistent with the RadLex Playbook ID, if participating in the Dose Index Reg...
Low dose CT protocol at 50mAs can produce the screening results consistent with standard dose CT protocol (150mAs), supporting routine use of low dose chest CT protocol. 展开 关键词: Radiation dose reduction Chest CT Diagnostic accuracy
Prior to enrolment, chest high-Resolution CT (HRCT) examination was obtained from all patients during the acute phase of the disease. The inclusion criterion was the confirmation of diagnosis of COVID-19 through RT-PCR performed on nasopharyngeal swabs samples. Patients with concurrent pulmonary ...
Validation Using Multiple Cardiac CT and Chest CT Protocols CT中的深度学习用于自动钙评分:使用多个心脏CT和胸部CT协议的验证 Background 背景 Although several deep learning (DL) calcium scoring methods have achieved excellent performance for specific CT pro tocols, their performance in a range of CT ex...
additional information compared with chest radiography regarding the nature of intrathoracic disease in critically ill children, (2) to determine whether such information alters clinical management, (3) to assess the role of a low-dose high-resolution CT (HRCT) protocol in pediatric ICU (PICU) ...
Generalization of PANDA to chest computed tomography One major difference between chest CT and abdominal CT is that the pancreatic and lesion regions are sometimes partially scanned in chest CT, depending on the different scanning ranges of the protocol and the anatomy of the patient. This difference...
An axial chest CT scan without contrast agent was applied. The protocol started with a scout view from lung apices to lung bases in anterior–posterior (AP) and lateral views, and followed by an axial chest scan covering lung apices through bases from inferior to superior. The parameters were...
目的:测定低剂量CT基线时附着于肋胸膜上的非钙化实性结节(CP-NCNs)的频率,并确定其主要特征。 材料和方法:对1992年至2019年西奈山早期心肺活动计划筛选队列中8730名参与者的基线低剂量CT扫描进行回顾性分析。包括一个或多个平均直径在3.0 mm到30.0 mm之...
The exclusion criteria were arms-down position (96 cases), reconstruction FOV smaller than the patient’s body size leading to truncation (459 cases), presence of metallic respiratory aiding equipment in the FOV (12 cases), high-resolution sequential acquisition mode images with table increment ...
