Abstract: Standard multidetector computed tomography (MDCT) uses a single X-ray tube to emit a mixed energy X-ray beam, which is received by a single
detector. The difference is that dual-energy CT (DECT), a new equipment in recent years, employs a single X-ray tube or two X-ray tubes to emit
two single-energy X-ray beams, which are received by a single or two detectors. The application of dual-energy technology to portal venography
has become one of the research hotspots. This paper will elaborate on the clinical application values of DECT portal venography in improving
portal vein image quality, distinguishing the nature of portal vein thrombus, reducing contrast agent dose and radiation dose, and will discuss the
possibility of its movement from research to routine practice and future development opportunities.
