Contrast CT, or contrast enhanced computed tomography (CECT), is X-ray computed tomography (CT) using radiocontrast. Radiocontrasts for X-ray CT are generally iodine-based types. This is useful to highlight structures such as blood vessels that otherwise would be difficult to delineate from their surroundings. Using contrast material can also help to obtain functional information about tissues. Often, images are taken both with and without radiocontrast. CT images are called precontrast or native-phase images before any radiocontrast has been administrated, and postcontrast after radiocontrast administration.

  • Болюсное контрастное усиление — один из наиболее распространённых методов контрастного усиления в компьютерной томографии, посредством внутривенного введения автоматическим инъектором контрастного препарата со скоростью от 2 до 7 мл в секунду. С этой целью применяют, как правило, неионные йодсодержащие препараты из расчета 2 мл на 1 кг массы обследуемого. Данный метод позволяет оценивать структуру сосудов (КТ-ангиография), выявлять и оценивать поражение паренхиматозных органов и др. (ru)
