Computed Tomography (CT) and Magnetic Resonance Imaging (MRI) are both used as crosssectional imaging methods for the detection of a variety of brain lesions in humans and animals. Each method has specific advantages and disadvantages to detect selected lesion characteristics. CT VERSUS MRI CT X-...

近年来,CT图像算法中基于深度学习的图像重建(DLIR)技术不断发展,日益成熟,目前已经逐步应用于临床实践中。DLIR算法较常规迭代重建算法具有在降低辐射剂量和图像噪声的同时不改变图像纹理,保持或提高解剖细节显示能力、总体图像质量和医生诊断信心的众多优势。因此,笔者重点就DLIR算法的原理、优劣势及其在人体各系统的临床...

我们试图确定超声、CT、MRI或PET‐CT对混合或未明确描述的成人皮肤侵袭性黑色素瘤患者全身成像(检测任何转移)的诊断准确性。 对于经历初级分期或再分期(可能复发)的研究受试者,以及混合或不明确的人群,我们的目标是: • 确定超声、CT、MRI或 PET‐CT检测淋巴结转移的诊断准确性; • 确定超声、CT、MRI或PET‐...
Objective: Aim of the study was to compare image quality of spiral (helical) versus conventional (sequential) routine brain scans obtained on a spiral CT scanner of the latest generation. Materials and methods: In a prospective study 60 patients scheduled for cranial CT were examined in spiral ...
