Time‐resolved contrast‐enhanced 3D MR angiography

Korosec, Frank R., Frayne, Richard, Grist, Thomas M., Mistretta, Charles A.·1996·Magnetic Resonance in Medicine

Abstract

An MR angiographic technique, referred to as 3D TRICKS (3D time‐resolved imaging of contrast kinetics) has been developed. This technique combines and extends to 3D imaging several previously published elements. These elements include an increased sampling rate for lower spatial frequencies, temporal interpolation of k‐space views, and zero‐filling in the slice‐encoding dimension. When appropriately combined, these elements permit reconstruction of a series of 3D image sets having an effective temporal frame rate of one volume every 2‐6 s. Acquiring a temporal series of images offers advantages over the current contrast‐enhanced 3D MRA techniques in that it i) increases the likelihood that an arterial‐only 3D image set will be obtained, ii) permits the passage of the contrast agent to be observed, and iii) allows temporal‐processing techniques to be applied to yield additional information, or improve image quality.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
