Samenvatting
Concise guide to the essential components of Computed Tomography
Rad Tech’s Guide to Clinical Computed Tomography offers a clear and concise exploration of the essential principles and practices of clinical CT. Presented in an accessible format, the book blends foundational knowledge with the latest advancements in the field, including the integration of artificial intelligence (AI) and photon-counting computed tomography (PCCT). It also provides practical tools to help readers prepare for computed tomography registry examinations.
Core topics include patient care principles for safe, effective, and ethical imaging; standard protocols for imaging neuroanatomy, musculoskeletal and thoracic systems, and abdominopelvic structures; interventional CT techniques; and quality assurance measures. The guide further explores the rapidly evolving landscape of CT, highlighting innovations such as remote scanning—technology that enables technologists to operate CT systems from off-site locations.
Readers will find:
- Clinical applications of AI and PCCT, emphasizing their potential to enhance diagnostic accuracy and workflow efficiency
- Guidelines for the safe administration of contrast media, including patient screening and premedication protocols
- Key considerations in radiation safety, covering photon interactions, dose metrics (CTDI and DLP), and strategies to minimize exposure
- Protocol recommendations for imaging the neurological, musculoskeletal, thoracic, and abdominopelvic systems, along with interventional CT techniques and quality assurance measures
Rad Tech’s Guide to Clinical Computed Tomography is an essential learning resource for students and new technologists in radiography, nuclear medicine, radiation therapy, and those pursuing post-primary CT certification, as well as for practicing technologists seeking up-to-date knowledge of emerging technologies and best practices.
