PROBLEM TO BE SOLVED: To provide an X-ray imaging apparatus which allows an operator to easily determine an appropriate direction of rotation of a guide wire during percutaneous coronary intervention treatment by providing information showing the running direction of a blood vessel. SOLUTION: In an X-ray angiography imaging apparatus, a three-dimensional blood vessel core line extracting section 142 forms a three-dimensional blood vessel core line showing a core line of a blood vessel, which is the imaging object, on the basis of three-dimensional volume data obtained from an image taken by an X-ray CT apparatus. A blood vessel running direction information image forming section 145 forms a blood vessel running direction information image in which a two-dimensional blood vessel core line display made by projecting the three-dimensional blood vessel core line is modified, on the basis of positional information of the three-dimensional blood vessel core line formed by the three-dimensional blood vessel core line extracting section 142, to show the running direction of the blood vessel. A blood vessel running direction information displaying X-ray image display section 149 superimposes the blood vessel running direction information image formed by the blood vessel running direction information image forming section 145 on an X-ray image, and displays them on a display section 7.
