概括
来自CT扫描的放射性特征与Sjögren综合征的唾液腺功能相关,提供了潜在的非SPECT/CT成像方法. 这种方法对评估唾液腺功能有希望,特别是在Sjögren综合征患者中.
科学领域:
- 医疗成像医学成像
- 放射学 放射学是一门学科.
- 核医学就是核医学.
背景情况:
- 唾液腺功能障碍是Sjögren综合征的一个关键特征.
- 下下状质病是另一种常见的唾液腺疾病.
- 评估唾液腺功能通常涉及功能性成像,如SPECT/CT.
研究的目的:
- 研究计算机断层扫描 (CT) 的放射性特征与唾液腺 SPECT/CT 的标准化吸收值 (SUVmean) 之间的关系.
- 为了区分Sjögren综合征和下下状质病之间的放射性CT发现.
- 探索CT放射学在唾液腺功能评估中的潜力.
主要方法:
- 对13名患者进行CT和SPECT/CT成像 (7例Sjögren,6例sialolithiasis).
- 使用技术-99m计算了SUVmean在刺激前和后.
- 使用PyRadiomics从CT图像中提取了放射性特征,不包括由于金属文物而导致的形状特征.
- 使用Spearman的相关性和回归分析来评估SUV平均比率和放射性特征之间的关系.
主要成果:
- 在Sjögren综合征 (1.30) 和石病 (2.35) 之间,SUV前后平均比率的中位数不同.
- 在Sjögren综合征中,四个放射性特征 (忙碌度,能量,总能量,高灰度强调) 与SUV平均比率 (p<0.02) 有很强的相关性.
- 在下下石病中,放射性特征和SUV平均比率之间没有发现显著的相关性.
结论:
- 在Sjögren综合征中,CT衍生的放射性特征与唾液腺功能 (SUV平均比率) 有着强烈的相关性.
- 这些发现表明CT放射学可能提供一种非侵入性方法来评估唾液腺功能.
- CT放射学的实用性似乎特定于诸如Sjögren综合征之类的疾病,不适用于所有唾液腺病理.

Radiological Investigation III: Pulmonary Angiogram and PET Scan
171
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...

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...
