PROBLEM TO BE SOLVED: To control the shading of an aspirating needle to a desired width by providing a means for switching an image pickup condition during radioscopic image pickup operation for continuously displaying an image in real time to control the shading of a specified object in a tested body to a desired width, and displaying plural images different in shading width. SOLUTION: A CPU 7 and an operating part 8 are provided with a function of switching an image pickup contition during image pickup operation and controlling the shading of a specified object in a tested body to a desired width. The advance of an aspirating needle is monitored, and simultaneously radioscopic image pickup operation is conducted. When the width of shading of the aspirating needle is too thick, during the radioscopic image pickup operation, the sequence type is switched from GrE(gradation echo) method to SE(spin echo) method, or the read inclined magnetic field intensity of the radioscopic image pickup sequence is increased. When the shading width is too thin, switching from SE method to GrE method is performed or the read inclined magnetic field intensity of the radioscopic image pickup sequence is decreased. Thus, it is possible to display an image different in shading width according to the advance state of the aspirating needle.
