摘要： MRI k-space data is acquired for a patient ROI during data acquisition sequences including a nuclear magnetic resonance (NMR) signal readout period using a late gadolinium enhanced (LGE) data acquisition sequence including at least one fat-specific RF NMR magnetization inversion pulse imposed (a) after a water-specific RF NMR magnetization inversion pulse timed to cause a substantial null in NMR magnetization of normal tissue protons near a center of the readout period and (b) before the readout period center, which fat-specific inversion pulse is also timed to cause a substantial null in NMR magnetization of fat tissue protons near the readout period center. The acquired MR image data is reconstructed into a contrast enhanced LGE image of tissues within the ROI but having substantially suppressed normal and fat components therein.

摘要： A magnetic resonance imaging apparatus according to an exemplary embodiment includes a memory, a specifying unit, and a display controller. The memory stores a corresponding color table representing correspondence relationships between T1 values of which value ranges with respect to each tissue are known and colors to be assigned to pixels with the T1 values. The specifying unit analyzes a T1-valued image and specifies colors to be assigned to each pixel on the basis of T1 values converted from pixel values of each pixel and the corresponding color table. The display controller displays on a display the image color-coded with the specified colors.

摘要： A magnetic resonance imaging (MRI) system obtains an MR image of an object. The system detects an ECG signal and performs a pulse sequence of RF gradient magnetic fields toward the object. Imaging defined by the pulse sequence is longer in temporal length than one heartbeat. The system further acquires an MR signal from the object in response to performance of the pulse sequence and produces the MR image based on the acquired MR signal. Also possible are: a plurality of divided MT pulses instead of the conventional single MT pulse, an SE-system pulse sequence having a shorter echo train spacing, and the generation of sounds by applying gradient pulses incorporated in an imaging pulse sequence so as to automatically instruct a patient to perform an intermittent breath hold.

摘要： A magnetic resonance imaging (MRI) system uses an MRI system gantry, an associated controlling computer system and an operator input mechanism, with the controlling computer system including at least one programmed computer configured to effect an automated magnetic resonance venography (MRV) mode. Operator inputs are accepted to preset parameters defining at least one MRV process (i) for acquiring plural sets of image data and (ii) for subsequent interrelated subtractions between the acquired image data sets to produce an MRV image set. The image data sets are thereafter automatically acquired and interrelated subtractions are automatically performed to produce an MRV image data set. The MRV image data set (perhaps after MIP processing) is then output to at least one of (i) an image data memory, (ii) an image display, and (iii) a remote further computer site.
