Real- Time Reduction of Motion Artefacts Using K-space Weighting in Magnetic Resonance Imaging
An improved version of motion-adapted gating useful in MR imaging is presented. Compared to other gating approaches, this advances method shows an improved ability to suppress motion artefacts at a reduced scan time. It is based on a k-space dependent weighting function and a realtime system feedback. During MR data acquisition patient motion ismonitored and only those profiles are accepted who...
متن کاملMagnetic resonance imaging-guided occult breast lesion localization and simultaneous sentinel lymph node mapping
BACKGROUND Radio-guided occult lesion localization is a valid technique for the diagnosis of suspicious non-palpable lesions. Here we determine the feasibility of pre-operative localization of occult suspect non-palpable breast lesions using radio-guided occult lesion localization, as well as for identifying the sentinel lymph node. METHODS This is a descriptive study of data collected retros...
متن کاملMotion artifacts in quantitative magnetic resonance imaging.
Several investigators have emphasized the potential value of quantitative relaxation times in the assessment of diseases. In performing such measurements using the spin-echo technique, we have encountered several anomalous results, whereby the intensity of the organ parenchyma on second-echo images is greater than on first echo images. This is most likely a result of respiratory motion, and it ...
متن کاملReal-Time Magnetic Resonance Imaging (MRI) during Active Wrist Motion—Initial Observations
BACKGROUND Non-invasive imaging techniques such as magnetic resonance imaging (MRI) provide the ability to evaluate the complex anatomy of bone and soft tissues of the wrist without the use of ionizing radiation. Dynamic instability of wrist--occurring during joint motion--is a complex condition that has assumed increased importance in musculoskeletal medicine. The objective of this study was t...
