Problems solved by technology

Song et al suggested that data from additional slices could be acquired, but pointed out that the number of possible slices is limited by the time window in which the blood magnetization is demagnetized

Embodiment Construction

[0014] There are a large number of possible implementations of the present invention, which are not described herein. Some currently preferred possible implementations are described below. However, it is very important to stress that these are descriptions of implementations of the invention, not descriptions of the invention, which is not limited to the detailed implementations described in this section, but is described in a broader form in the claims .

[0015] The following description is sufficiently sufficient to enable those skilled in the art to construct the disclosed implementations. Unless otherwise stated, the mentioned procedures and fabrication methods are known to those skilled in the art.

[0016] exist figure 1 and figure 2 In the preferred implementation shown, an ECG-triggered pulse train is used. The sequence includes two DIR prep pulse modules within each RR interval, with data acquisition from three slices (eg, S11, S12, S13) following each DIR modu...

Abstract

DIR imaging of blood vessels by administering a series of DIR preparation pulse modules at a repetition interval short enough that at least two DIR preparation pulse modules generally occur within each RR interval, and by acquiring image data for a plurality of slices following each DIR module.

Description

technical field [0001] The present invention relates to magnetic resonance imaging of blood vessel walls. Background technique [0002] Atherosclerosis and its thrombotic complications are major causes of morbidity and mortality in developed countries. Non-invasive atheroma determination using high-resolution magnetic resonance imaging (MRI) has been shown to be feasible in the human aorta, carotid and coronary arteries. Flow suppression (ie, black blood imaging) is necessary for vessel wall visibility and to prevent flow artifacts that can affect image quality and interpretation. Black blood techniques include spatial presaturation ("Real-time black blood MRI using spatial presaturation" by Nayak et al., J Magn Reson Imaging 2001;13:807-12) and a double inversion recovery (DIR) pre-pulse module (Simonetti et al. "'Black blood' T2-weighted inversion recovery MR imaging of the human heart" Radiology 1996;199:49-57). [0003] The DIR prep pulse module typically consists of ...
