    摘要： In a magnetic resonance angiography method with flow-compensated and flow-sensitive imaging and a magnetic resonance apparatus for implementing such a method, a first MR data set of the examination region is acquired with an imaging sequence in which vessels in the examination region are shown with high signal intensity, a second MR data set of the examination region with an imaging sequence in which the vessels in the examination region are shown with low signal intensity, and the angiographic magnetic resonance image is calculated in a processor by taking the difference of the first and second data set. The first data set is acquired with an imaging sequence with reduced flow sensitivity and the second data set is acquired with an imaging sequence with an increased flow sensitivity compared to the initial imaging sequence.

    摘要： In a method and device to evaluate a time series of in particular two-dimensional images of a contrast agent flow in at least one blood vessel of the human body within the scope of a test bolus measurement, wherein the acquisition of the time series begins with administration of the contrast agent, the time series of two-dimensional images or a time series of images derived from this is used as a time series of evaluation images, and in at least one evaluation image exhibiting a contrast agent signal, at least one point associated with a blood vessel is determined semi-automatically or automatically and transferred to further evaluation images. For every blood vessel discovered in this way, a temporal contrast agent course curve is determined (in particular via a fit) automatically from the image signal of the evaluation images at the at least one point and/or in a region around the marked point in the blood vessel and at least one item of contrast agent information that affects the temporal workflow of a subsequent measurement is determined from at least one contrast agent course curve.

    摘要： In a method and magnetic resonance tomography apparatus for triggered implementation of a measurement (composed of partial measurements) in the magnetic resonance tomography apparatus, at least one image data set is determined from the data acquired within the scope of the partial measurements, and for triggering a reference point of the movement phase of the movement is used. The image data set is acquired in segments; the reference point is detected by a control device independent of a partial measurement, and the partial measurement following the detected reference point is conducted depending on the independently detected reference point. The wait time that specifies the interval from the end of the partial measurement to the beginning of the next partial measurement is adapted depending on the point in time of detection.
