A magnetic resonance imaging system is disclosed to perform an imaging pulse sequence that acquires data to generate an image of at least a portion of the patient. The magnetic resonance imaging system comprises an acoustic transducer to irradiate an anatomic structure in the patient using ultrasonic energy. A receiver, in response to ultrasonic energy, generates echo signals. Using the echo signals, a signal analyzer generates a plurality of gating signals, including a first gating signal in response to a first period of motion of the anatomic structure and the second gating signal in response to a second period of motion of the structure. The magnetic resonance imaging system, in response to the first gating signal, acquires data from the center of k-space, and, in response to the second gating signal, acquires the periphery of k-space.

Current bolus chase magnetic resonance angiography is limited by the imaging time for each station. Tailoring the density of k-space sampling along the anterior-posterior direction of the coronal station allows a substantial decrease in scan time that leads to greater contrast bolus sharing among stations and consequently a significant improvement in image quality. Fast arterial-venous transit in the carotid arteries requires accurate, reliable timing of the acquisition to the bolus transit to maximize arterial signal and minimize venous artifacts. The rising edge of the bolus is not utilized in conventional elliptical-centric view ordering because the critical k-space center must be acquired with full arterial enhancement. The invention provides a recessed elliptical-centric view ordering scheme is introduced in which the k-space center is acquired a few seconds following scan initiation. The recessed view ordering is shown to be more robust to timing errors in a patient studies.

In time-resolved contrast-enhanced magnetic resonance angiography, a measure quantifying image quality provides a basis for generating a linear filtered composite image by facilitating selection of a mask and an arterial phase image for subtraction. Filtering of individual pixels of a temporal series of images provides enhanced contrast in a single image by allowing the temporal behavior of the pixel intensity to denote representation as an artery, vein or background tissue. Motion artifacts are suppressed by re-registering sequential images, adjusting weighting before averaging and subtraction and filtering the Fourier data to eliminate data corrupted by motion or other phenomena.

The present invention is a technique and apparatus for acquiring anatomic information used in diagnosing and characterizing abdominal aortic aneurismal disease and the like. This technique provides anatomic information, in the form of images, using a combination of a plurality of magnetic resonance angiography sequences, including a spin-echo and four contrast enhanced (e. g. , gadolinium) magnetic resonance angiography sequences. The anatomic images may be used in, for example, pre-operative, operative and post-operative evaluation of aortic pathology, including aneurysms, atherosclerosis, and occlusive disease of branch vessels such as the renal arteries. The gadolinium-enhanced magnetic resonance angiography provides sufficient anatomic detail to detect aneurysms and all relevant major branch vessel abnormalities seen at angiography operation. This technique and apparatus allows for imaging the aorta at a fraction of the cost of conventional aortography and without the risks of arterial catheterization or iodinated contrast.

The present invention is a technique and apparatus for providing preferential enhancement of an artery of interest relative to adjacent veins and background tissue by correlating the collection of a predetermined portion of data (for example, image data which is representative of the central portion of k-space) of a magnetic resonance contrast image during the arterial phase of the magnetic resonance contrast enhancement.

There are many inventions described herein as well as many aspects and embodiments of those inventions. A thigh compression device and technique to control, time, delay and/or prevent excessive early venous enhancement relative to arterial enhancement and thereby improve and/or enhance MRA images, including peripheral MRA images. In one embodiment, the present invention uses a curved strip of material which is longer on the superior edge and shorter along the inferior edge. When wrapped around the conical or conal-like shape of the thigh of a subject (for example, a human), the thigh compression device more uniformly conforms to and/or fits around the thigh, providing more even/uniform compression as well as reducing, minimizing and/or eliminating significant movement of the thigh compression device towards the knees of the subject. Notably, a snug fit on the thighs may also enable the thigh compression device to be inflated with less fluid (for example, air) which is faster and less cumbersome for the operator.
