Abstract:
An MRI apparatus which images a subject in such that body fluid that flows is emphasized over background tissues, includes a first coil control device that causes a transmission coil and a gradient coil to execute a first pulse sequence for causing longitudinal magnetization components of the background tissues to differ from a longitudinal magnetization component of the body fluid, a second coil control device that causes the transmission coil and the gradient coil to execute a second pulse sequence that inverts the longitudinal magnetization components of the body fluid and the background tissues a plurality of times after the execution of the first pulse sequence, and a third coil control device that causes the transmission coil and the gradient coil to execute a third pulse sequence for acquiring each MR signal of the body fluid after the execution of the second pulse sequence.
