Embodiment Construction

[0013] refer to figure 1 , shows a patient 10 being treated for cardiovascular disease. A patient 10 is placed in the imaging field of a magnetic resonance scanner 20 . The scanner is included for generating B in the imaging area 0 The main magnetic field magnet 22 of the field. gradient coil 24 across the B 0 field, usually gradient magnetic fields are induced along three orthogonal axes. The whole body RF coil 26 transmits RF pulses to excite and manipulate resonance within the patient in the imaging region. The whole body RF coil optionally also receives RF resonance signals from the examination region. A surface or other local RF coil 28, if present, receives the resonant signal. Optionally, the local coil is also capable of inducing and manipulating resonance. A sequence controller 30 controls the RF and gradient coils to achieve a selected magnetic resonance imaging sequence. Sequence memory 32 stores DWI, PWI, MRA and other imaging sequences. A reconstruction p...

Abstract

A system for early detection and treatment of catheter-induced ischemic stroke includes a magnetic resonance system (20) and a processor (36). The magnetic resonance system includes: a sequence controller for performing each of a plurality of imaging sequences; and a sequence memory (32) for storing at least a magnetic resonance angiography (MRA) sequence, a diffusion weighted imaging (DWI) sequence, and Perfusion-weighted imaging (PWI) sequences. The processor is programmed to control the magnetic resonance system to perform the steps of: performing an MRA sequence to generate a baseline MRA image; performing a catheter tracking procedure to track the catheter; performing a DWI sequence after the catheter procedure to generate a diffusion-weighted image; performing a PWI sequence to generate a perfusion-weighted image; and combine the diffusion-weighted image and the perfusion-weighted image to generate a combined image for evaluating ischemic stroke.

Description

technical field [0001] The following relates to the medical field, the imaging field, the magnetic resonance field and related fields. The invention finds particular application in the detection of stroke and is described with particular reference thereto. Background technique [0002] Stroke often represents a drastic change in a patient's quality of life, associated with significant costs of rehabilitation and permanent disability. A stroke can include occlusion or blockage of a blood vessel, as well as rupture of a blood vessel. Treatment of cardiovascular disease through transvascular catheter interventions is associated with a greater risk of stroke. When performing such interventions in the left heart, the aortic arch, carotid artery or cerebral vasculature are exposed to the risk of acute ischemic stroke during the procedure. Risk increases with procedure time and catheter size. Common examples of this risk include coronary angiography, coronary balloon angioplast...
