概括
手持式CrystalCam有效地识别了黑色素瘤患者的哨兵淋巴结 (SLN),与传统方法具有很高的一致性. 该设备是缺乏核医学设施的手术中心的可靠工具.
科学领域:
- 医疗成像医学成像
- 核医学就是核医学.
- 手术瘤学手术瘤学
背景情况:
- 传统的玛摄像机经常被占用,因此需要替代性解决方案来进行淋巴细胞检测.
- 在手术室中对实时哨兵淋巴结 (SLN) 定位的需求推动了先进的成像设备的开发.
- 基于高分辨率半导体探测器的手持玛摄像头,如CrystalCam,已经出现,以满足这些需求.
研究的目的:
- 为了评估CrystalCam手持马摄像头用于哨兵淋巴结 (SLN) 定位的有效性.
- 为了比较CrystalCam与常规平面淋巴细胞切割和混合SPECT/CT在识别恶性黑色素瘤患者的SLN的性能.
- 评估CrystalCam在手术环境中的可靠性,特别是在没有专门的核医学部门的中心.
主要方法:
- 幻影研究是使用一个充满99mTc的Jaszczak幻影进行的,以测量CrystalCam在各种距离上的灵敏度.
- 一项临床研究涉及40名连续患有恶性黑色素瘤的患者,以比较CrystalCam与平面淋巴切片和SPECT/CT用于SLN检测.
- 用紫外线标记器和笔标记SLN,分析成像方式和SPECT/CT作为参考标准之间的一致率.
主要成果:
- 幻影研究表明,CrystalCam的活动和计数率之间存在良好的相关性.
- 在恶性黑色素瘤患者中,CrystalCam和平面淋巴细胞扫描分别检测到58个和61个SLN,一致率高达95.65%.
- 虽然CrystalCam在SLN检测方面是有效的,但它在统计学上低于平面成像,用于识别更高梯级节点 (13vs48).
结论:
- 手持式CrystalCam是一个可靠的工具,用于定位哨兵淋巴结 (SLNs).
- 它在SLN检测中的性能与传统的平面淋巴淋巴镜相提并论.
- 对于没有现场核医学部门的手术中心,CrystalCam提供了一个有价值的解决方案.

Radiological Investigation III: Pulmonary Angiogram and PET Scan
117
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...
