ECT成像的基本原理:放射性药物引入人体,经代谢后在脏器内ECT外或病变部位和正常组织之间形成放射性浓度差异,将探测到这些差异,通过计算机处理再成像。ECT成像是一种具有较高特异性的功能显像和分子显像,除显示结构外,着重提供脏器与端正变...

Deep learning enhanced ultra-fast SPECT/CT bone scan in patients with suspected malignancy: quantitative assessment and clinical performance 文中提出通过深度学习增强的1/7扫描时间的超快速SPECT/CT骨扫描可以获得与标准扫描相当的图像。此次研究成果受到《Physics in Medicine & Biology》认可,是对影动医疗研发技...
Purpose of Review The purpose of this review is to evaluate the role of SPECT/CT in identifying facet joint arthropathy and the outcomes of interventions with SPECT/CT as an adjunct. Recent Findings A positive finding of facet arthropathy on SPECT/CT is associated with a higher likelihood of ...
为解决全膝关节置换术(TKA)后不明原因膝前痛(AKP)的诊断和二次髌骨表面置换(SPR)疗效不确定的问题,研究人员开展了使用单光子发射计算机断层扫描 / 计算机断层扫描(SPECT/CT)联合三相骨扫描(TPBS)评估 SPR 适用性的研究,结果显示该联合检查可助力评估,意义重大。
The team completed a whole-body scan in 20 minutes using parameters of 3 seconds per view with 60 projections in continuous acquisition mode, forgoing the traditional step-and-shoot approach, for a 113 kg/249 lb-patient. “I think it has all the information you need about the bone.” ...
结果来自于nanoScan SPECT/CT 手术后一小时马上对大鼠进行SPECT/CT 扫描(以确定基线非灌注区域)。在 Sprague-Dawley 大鼠中,[99mTc]Tc-sestamibi 从血液中迅速清除并在心脏中被吸收,几乎没有再分布。因此,在注射 SAX 或安慰剂前 20 分钟注射 [99mTc]Tc-sestamibi,可以在第一次SAX注射的任何潜在影响之前检测到非...

(1)故障现象。CT扫描时报错,前台故障报错信息为“Resources allocation for scan failed”。 (2)故障分析与处理。该报错提示CT检查尚未做好准备,由于CT设备正常工作与多种因素相关,若CT设备自身硬件故障、周边环境温度过高或数据传输断开等均能引起CT无法正常工作。查看环境温度为23 ℃,在正常范围之内,按照处理流程重启...
