概括
通过SPM (ISAS) 分析的直肠直肠SPECT提供了与SISCOM相比的或更好的结果,用于识别手术候选人的发性区域. ISAS提供了更好的解释性,是临床使用的可靠替代方案.
科学领域:
- 神经学 神经学
- 医疗成像医学成像
- 发病学 (Epileptology) 是一个专业的学科.
背景情况:
- 阴道单光子发射计算机断层扫描 (SPECT) 对于估计焦点的发性区域至关重要.
- 减去ictal和interictal的SPECT扫描可以识别过度透的区域,但生理差异纠正是具有挑战性的.
- 扫描器特定的控制数据库是理想的,但由于道德问题,很难获得.
研究的目的:
- 为了比较由SPM (ISAS) 分析的Ictal-Interictal SPECT与MRI (SISCOM) 共同注册的减去Ictal SPECT的有效性.
- 通过使用公开可用的控制数据库来评估ISAS,作为SISCOM的替代品,用于手术工作.
主要方法:
- 从26名焦点耐药性患者 (7-50岁) 的SPECT扫描进行了回顾性分析.
- 使用公开可用的ISAS控制数据库对SISCOM和ISAS算法的比较.
- 盲目评审者对阴道溢血位置的评估,并与切除区域或疑似发性区域进行比较.
主要成果:
- 在54%的患者中,ISAS和SISCOM确定了相同的高 perfusion 位置.
- 在ISISCOM没有发现的6名患者中,ISAS在6名患者中局部化了高 perfusion.
- 与SISCOM相比,ISAS表现出更高的准确性 (65%对55%) 和更好的最大溢血局部化 (65%对38%) .
结论:
- 使用公共控制数据库的ISAS,为SISCOM提供了与SISCOM相似或更好的结果,用于识别发性区域.
- ISAS提供了更易于解释的结果,是手术诊所可靠,易于实施的替代方案.
- ISAS是一个有前途的选择,特别是对于缺乏特定控制SPECT数据集的中心.

Radiological Investigation III: Pulmonary Angiogram and PET Scan
Radiological investigations are paramount in the diagnosis and management of various pulmonary diseases. Two essential investigations are the Pulmonary Angiogram and the Positron Emission Tomography (PET) Scan.
Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...

Imaging Studies II: Positron Emission Tomography and Scintigraphy
Positron Emission Tomography (PET) is a medical imaging technique that provides crucial insights into the body's physiological functions at a molecular level. It is an indispensable resource for diagnosing, staging, and monitoring various illnesses, notably cancer, neurological disorders, and cardiovascular conditions.
