1 核医学科SPECT-CT 分子影像 即发射型计算机断层扫描仪,简称“ECT”。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...
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 hig...
The purpose of this review on SPECT/CT radiation dosimetry is to provide updated information on the total effective dose and total equivalent doses to critical organs due to both radiopharmaceutical administration and CT scan modality for both adults and pediatric patients. The use of new solid-...
For this reason, studies that rely on exact quantification should avoid the use of contrast- enhanced CT images for attenuation correction. Further- more, for organs which are affected by motion, a mismatch between the emission and the transmission scan will likely introduce errors into the ...
While there is already a long history of PVC in emission tomography, there is no definitive solution on handling small volumes in SPECT/CT [25]. The results from the NEMA IEC body phantom confirm the importance of spatial orientation with the scan field, with a significantly different recovery...
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...

Planar post-ablation 131I-iodide scan (a) shows multiple sites of intense uptake in the neck and upper mediastinum consistent with known metastatic spread. There is an additional area of focal tracer accumulation of moderate intensity in the right pelvis (arrow). SPECT/low-dose CT slices and ...
