Non-contrast Cardiac CT Images Dataset with Coronary Artery Calcium Scoring

The database investigated the association between cardiac fat volume and coronary artery disease (CAD). This dataset includes 14,127 non-contrast computed tomography (CT) slices of 120 patients diagnosed with CAD using an assessment of coronary artery calcium scoring by a cardiovascular specialist and radiologist, with 43 patients having coronary artery disease and the rest of the patients in the healthy individuals' group.
Findings of Coronary artery calcium (CAC) in cardiac CT have been demonstrated to be a reliable and strong marker of coronary artery atherosclerosis. CAC represents one-fifth of the total plaque burden, indicating a high linear correlation with the second root of total pathologic plaque levels (r = 0.90; p <0.001). CAC may be a more sensitive and specific determinant of CAD risk than conventional CAD risk factors, which may indicate over- and under-diagnosis in arterial atherosclerosis. CAC scanning is a non-contrast-enhanced image acquisition technique that is performed while holding a breath. The weighted sum of CAC is defined by areas in the coronary artery with Hounsfield unit values greater than 130 including three or more adjacent pixels. Standard CAC classifications based on studies generally agree that CAC values of 0 to 10 indicate no calcified plaque, and values of 11 to 100, 101 to 400, and more than 400 indicate mild, moderate, and severe CAC levels, respectively.
Between June 2017 and January 2019, this dataset was randomly collected from Parsian CT angiography medical center in shahid Madani hospital, Tabriz. As a statement, the Ethics Committee of Tabriz University of Medical Sciences approved this study (approval ID: IR.TBZMED.REC.1398.122).

本数据库探究了心脏脂肪体积与冠状动脉疾病（CAD）之间的关联。该数据集包含120名被心血管专家和放射科医生通过冠状动脉钙化评分方法诊断为CAD的患者的14,127张非对比增强计算机断层扫描（CT）切片，其中43名患者患有冠状动脉疾病，其余患者属于健康个体组。冠状动脉钙（CAC）在心脏CT中的发现已被证明是冠状动脉粥样硬化的可靠且强有力标志物。CAC占总斑块负荷的五分之一，表明其与总病理斑块水平的第二根存在高度线性相关性（r = 0.90；p < 0.001）。CAC可能比传统的CAD风险因素更敏感、更特异地决定CAD风险，这可能表明动脉粥样硬化的过度和漏诊。CAC扫描是一种在屏气状态下进行的非对比增强图像采集技术。CAC的加权总和由冠状动脉中Hounsfield单位值大于130的区域组成，包括三个或更多相邻像素。基于研究的标准CAC分类普遍认为，CAC值为0至10表示无钙化斑块，值为11至100、101至400以及超过400分别表示轻度、中度和重度CAC水平。该数据集于2017年6月至2019年1月期间，从位于塔布里兹沙希德·马丹尼医院的帕尔西安CT血管造影医学中心随机收集。伦理委员会对塔布里兹医科大学的研究予以批准（批准编号：IR.TBZMED.REC.1398.122）。
