核医学就是核医学.
瘤成像学成像学
放射性药物放射性药物放射性药物

背景情况:

淋巴结转移是肺癌分期和治疗的关键因素.
精确诊断淋巴结的参与对于有效的患者管理至关重要.
目前的成像方法在精确检测早期转移方面存在局限性.

研究的目的:

评估99mTc-3PRGD2 SPECT/CT在原发性恶性肺瘤中淋巴结转移的诊断性能.
在诊断肺癌淋巴结转移时,将99mTc-3PRGD2 SPECT/CT与18F-FDG PET/CT进行比较.
评估99mTc-3PRGD2 SPECT/CT根据原发性瘤吸收来预测转移的能力.

主要方法:

预计将招募26名患有原发性恶性肺瘤的患者.
99mTc-3PRGD2 SPECT/CT和18F-FDG PET/CT成像技术的性能.
淋巴结和肺瘤的定性和半定量分析.
组织病理学结果作为诊断的参考标准.

主要成果:

99mTc-3PRGD2 SPECT/CT显示了转移性和良性淋巴结之间的显著差异 (P < 0.001).
对99mTc-3PRGD2 SPECT/CT的半定量分析显示,淋巴结转移检测的AUC为0.908.
图像显示了淋巴结转移的高灵敏度 (86%) 和特异性 (88%).
只有在半定量99mTc-3PRGD2 SPECT/CT分析中 (P = 0.007) 才观察到原发性肺病变的显著差异.

结论:

99mTc-3PRGD2 SPECT/CT是一种有前途的成像工具,用于直接诊断肺癌中淋巴结转移的情况.
该技术还可以通过初级病变吸收间接预测淋巴结转移.
这种先进的成像技术为肺癌分期提供了更好的诊断准确性.

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...
