放射技师的结肠造影 CT：表现和图像解读指南

English | 2023 | ISBN-10: 3031308654 | 420 pages| PDF (True) | 43 MB

This second edition, comprising 28 chapters, explains every aspect of the role of radiographers in performing CT colonography (CTC) and interpreting CTC images with the aim of enabling radiographers to extend the scope of their practice. It provides information required with respect to communication with the patient, procurement of informed consent, the principles of CT as well as dual-energy CT and photon counting CT, radiation dose, patient preparation and positioning, the use of contrast media, the performance of diagnostic and screening CTC studies, the interpretation and reporting of images, legal and professional requirements, and the importance of clinical audits. A wide range of CTC findings is described and depicted, covering normal anatomy, artefacts, haemorrhoids, polyps, colon cancer, diverticular disease, lipomas, extracolonic structures, opportunistic screening for osteoporosis and metabolic associated fatty disease, and CTC in incomplete or failed colonoscopy. The role of other modalities such as ultrasound, magnetic resonance imaging, and nuclear medicine in colorectal cancer patients is discussed. In addition, the text covers the role of artificial intelligence and machine learning in imaging of the colon for the detection of polyps, diagnosis and staging of colorectal cancer. Lastly, a chapter focusing on self-assessment of image interpretation will aid learning.

This book provides the support that radiographers need in order to perform CTC studies to the standard required in terms of advances in imaging and interpretation of images.

第二版共包含28章，解释了放射技师在进行CT结肠成像（CTC）以及解读CTC图像时所扮演的角色，旨在使放射技师能够扩展其实践范围。它提供了与患者沟通、获得知情同意、CT的基本原理以及双能CT和光子计数CT的相关信息、辐射剂量、患者准备和定位、对比剂的使用、诊断和筛查CTC研究的执行、图像解读和报告、法律和专业要求，以及临床审计的重要性。 描述并展示了广泛的CTC发现，涵盖正常解剖学、伪影、痔疮、息肉、结肠癌、憩室病、脂肪瘤、结外结构、骨质疏松症及相关代谢性疾病的筛查机会以及在不完全或失败的结肠镜检查中的CTC。讨论了超声波、磁共振成像和核医学在 colorectal 癌患者中所扮演的角色。此外，本手册还涵盖了人工智能和机器学习在结肠影像学中用于检测息肉、诊断及结直肠癌分期的作用。 最后，一章专注于图像解读自评估将有助于学习。 这本书为放射技师提供了所需的支持，以便以符合成像技术进步及图像解读标准的方式进行CTC研究。
