An object of the present invention is to reduce the imaging time, the diagnosis time, and the breath-holding burden on a subject. An operator can arbitrarily set a TI value during photographing, and the TI value is immediately reflected in a photographing sequence when the TI value is set. When a region of interest is set in any one test image, the TI value is related to all other test images. A region of interest is set at the position, the minimum value of the signal value or the average value of the signal values is obtained for each region of interest in each test image, and the TI value when the test image having the minimum value is obtained is obtained. This value is set as the TI value of the main photographing, and is automatically performed until the main photographing is completed. Also, in the test shooting and the main shooting, the delay imaging can be accurately performed even in the non-breath-holding shooting using the navigator echo. [Selection diagram] FIG. |
