A magnetic resonance imaging apparatus according to an embodiment includes a collection unit and a generation unit. The collection unit collects data of an imaging area over a plurality of time phases within a certain respiratory cycle after applying a labeling pulse to a labeling area in which cerebrospinal fluid flows under a task of respiration. The generation unit generates images of a plurality of time phases depicting the cerebrospinal fluid by using the collected data.

According to one embodiment, a blood flow perfusion analyzing apparatus includes tissue and arterial TCC calculation units, first and second making units, a deconvolution unit and a blood flow information calculation unit. The tissue TCC calculation unit obtains tissue TCCs. The arterial TCC calculation unit calculates an arterial TCC. The first making unit makes first sets, starting from a first time in which elements corresponding to the tissue are arrayed one-dimensionally, based on the tissue TCCs. The second making unit makes a second set, starting from a second time after the first time, in which elements corresponding to the artery are arrayed two-dimensionally, based on the arterial TCC. The deconvolution unit calculates transfer functions of the tissue based on the first and second sets. The blood flow information calculation unit calculates information on a blood flow perfusion based on the transfer functions.

In a method and control sequence determination device for determination of a magnetic resonance system control sequence to generate an image series of a defined image region of an examination subject, the control sequence includes a multichannel pulse train with multiple individual RF pulse trains to be emitted in parallel by the magnetic resonance system via different independent radio-frequency transmission channels. The multichannel pulse train includes an excitation pulse to excite the image region and a subsequent number of refocusing pulses in order to respectively excite an echo signal to acquire raw data for an image of the image series. At least one defined marking region in the image region is determined depending on a subject structure to be depicted in the image region, and the multichannel pulse train is determined such that a saturation is achieved at or in the marking regions before the excitation pulse.

A method for marking an entry position for an injection apparatus on a surface of a patient positioned inside a patient receiving region of a magnetic resonance device. The method includes providing a virtual entry position, introducing a marking apparatus into the patient receiving region, acquiring time-resolved MR image data from the marking apparatus by the magnetic resonance device, ascertaining a current position of the marking apparatus based on the time-resolved MR image data, iteratively changing the current position of the marking apparatus using the virtual entry position and the current position, and delivering the liquid from the marking apparatus when the current position matches the virtual entry position.
