To prospectiveleyvaluate the effect of heart rate, malignantlesions.Performancoef needleaspiration heart rate variability,and calcificationdual-source computedtomography(CT) image quality and to prospectively assess diagnostic accuracy of dual-sourceCT for coronary artery stenosis. by using invasive coronary angiography as the reference standard. 前瞻性评价心率、心率变异性及钙化双源计算机断层扫描成像质量的影响及对冠状动脉狭窄的 双源性冠状动脉狭窄诊断的准确性评价。以侵入性冠状动脉造影为参照标准。 Chest radiographpylays an essential role in the diagnosis of thoracic disease and is the most frequentlyperformedradiologicexaminationin the United States.Since the discoveryof X rays more than a centuryago, advancesin technologyhave and needle localization procedures followed by excisional biopsy is frequently necessary to determine the origin of a mammographic finding. 虽然摄影是乳腺癌的形态学标准，乳房可见检测相当敏感，经常不足的恶性病变良性分化性能。穿刺针定位切除活检程序经常需要确定一X个线发现的起源 Therefore,initiatives have been taken among radiation protection authorities to give priority to investigationsof dose levels and frequenciesof X-ray examinations among children. The main objectiveis to establishrecommendationof upper dose limits for various diagnostic procedures and to yieled numerous improvements in thoracic imaging.implement minimum requirementsfor equipment Evolutionary progress in film-based imaging has ledstandards. to the development of excellent screen-film systems specifically designed for chest radiography. 因此，在辐射防护当局之间采取了主动行动，优先考 胸部X 线摄影中起着至关重要的作用在胸部疾病的诊虑儿童的剂量水平和频率的调查。主要目标是建立各 断，是最常用的影像学检查在美国。由于发X现射线 种诊断程序的上限的建议，并实施设备标准的最低要 的一个多世纪前，技术的进步得到了大量的改进，在求。 胸部影像。电影为基础的成像的进化进展，导致了专 门设计用于胸部放射摄影的优秀的屏幕膜系统的发 展。  Thus, the aim of our studywas to prospectively evaluate to what extent image quality in 16-detector row CT coronaryangiographyis a function of the heart rate and image reconstruction technique. 因此，我们的研究的目的是前瞻性评估在何种程度上 (3)althoughmammography is quite sensitive for the 的图像质量在16 检测器行冠状动脉造影是一个功能 detection of breast cancer morphologcicriteria that are mammographically visible are fr
