肝脏门静脉期CT增强的影响因素与对策
Contrast enhancement of abdominal CT at portal venous phase:considerations and solutions
摘要
Abstract
With the continuing development of computed tomographic (CT) technology, especially dual-energy CT (DECT), new clinical applications has been discovered based on the capability of material decomposition and improved image quality accordingly. Innovative CT technology has introduced new challenges in optimization of clinical radiology practice in return. One of the challenges is with contrast enhancement of upper abdominal CT at portal venous phase which is difficult to optimize due to the double blood supply. In this article, contrast medium, patient and CT scanning factors associated with contrast enhancement at portal venous phase were addressed and discussed. Published studies on improving image quality while reducing contrast medium dose and radiation dose were reviewed and interpreted. A new paradigm of individualized examination planning system based on dual-energy CT to optimize contrast medium administration and scanning protocol was proposed.关键词
