PROBLEM TO BE SOLVED: To provide a method and facility for quickly and safely inspecting articles of a liquid S by dual-energy CT imaging. SOLUTION: The method comprises the steps of: obtaining one or more CT images including physical attributes of liquid to be inspected using CT scanning and a dual-energy reconstruction method; acquiring the physical attribute value of each liquid to be inspected from the CT image by image processing and an analysis method; and determining whether the liquid article to be inspected is dangerous based on the physical attribute value. The CT scanning method can be implemented by a normal CT scanning technique or a spiral CT scanning technique. In the normal CT scanning technique, a series of specific positions can be set for scanning, or a scanning position can be set by an inspector using a DR (digital radiography) image, or the position of a liquid portion can be determined by an automatic analysis of the DR image to guide CT scanning.
