概括

使用国家综合癌症网络 (NCCN) 指导方针对肺结节随访建议的观察者间协议是温和的. 差异与结节类型和测量有关,影响肺癌查的一致性.

科学领域:

放射学放射学是指放射学
在瘤学瘤学.
医疗成像医学成像

背景情况:

肺结节的随访对于肺癌查至关重要.
持续的后续建议对于查的有效性至关重要.
亚固体结节需要特殊的管理协议.

研究的目的:

评估国家综合癌症网络 (NCCN) 基于指导方针的子固体结节的随访建议的观察者间协议.
确定导致后续推差异的因素.
评估肺癌查方案的一致性.

主要方法:

对于110个低剂量计算机断层扫描 (LDCT) 报告的回顾性分析,用于亚固体结节.
五位观察员根据NCCN的指导方针对随访建议进行了分类 (0-3-6-12个月).
用弗莱斯的卡帕和科恩的卡帕统计来评估观察者之间的一致性.

主要成果:

总体准确率为72.3%,与中度一致 (弗莱斯卡帕 = 0.437).
与居民相比,胸部放射科医生表现出相当大的一致性 (科恩的卡帕 = 0.655) (平均科恩的卡帕 = 0.533).
差异 (27.5%主要,4.8%实质性) 往往是由于结节类型 (部分固体) 和测量差异.

结论:

根据NCCN指导方针对亚固体结节的随访建议显示中等一致性.
部分固体结节和测量变化有助于后续推差异.
在肺癌查中,提高亚固体结节管理的一致性至关重要.

关键词:

肺癌是一种肺癌.低剂量计算机断层扫描 (LDCT)观察者变化的变化.亚固体结节的结节

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 III: Computed Tomography

DefinitionComputed Tomography (CT) of the genitourinary (GU) tract is a non-invasive imaging modality that utilizes X-rays and computer processing to generate detailed cross-sectional images of the urinary system, encompassing the kidneys, ureters, bladder, and adjacent structures such as the adrenal glands.PurposeCT scans of the GU tract serve several diagnostic and therapeutic purposes, including:Diagnosis of Urinary Tract Diseases: Detects kidney stones, tumors, cysts, and congenital...
