Key result
Diffusion-prepared turbo-spin-echo (DP-TSE) significantly improved carotid vessel wall visibility compared to conventional SS-DWEPI (84% vs 41%, p < 0.001) and detected lipid-rich necrotic cores.
Why the study?
Does 3D diffusion-prepared turbo-spin-echo (DP-TSE) CMR improve carotid vessel wall visibility and accurately detect lipid-rich necrotic core compared to conventional SS-DWEPI and contrast-enhanced CMR?

Does 3D diffusion-prepared turbo-spin-echo (DP-TSE) CMR improve carotid vessel wall visibility and accurately detect lipid-rich necrotic core compared to conventional SS-DWEPI and contrast-enhanced CMR?
Absolute Event Rate: 84% vs 41%
p-value: p=<0.001
3D diffusion-prepared turbo-spin-echo CMR provides high-resolution, contrast-free imaging of the carotid arterial wall, enabling accurate detection of lipid-rich necrotic cores, which is particularly valuable for patients with renal insufficiency.

May aid contrast-free carotid plaque assessment in renal impairment; hypothesis-generating pending prospective validation.
Xie et al. (2014) conducted a cross-sectional in Carotid atherosclerosis (n=21). 3D diffusion-prepared turbo-spin-echo (DP-TSE) vs. 2D single-shot diffusion-weighted echo-planar imaging (SS-DWEPI) was evaluated on Average vessel wall visibility (p=<0.001). Diffusion-prepared turbo-spin-echo (DP-TSE) significantly improved carotid vessel wall visibility compared to conventional SS-DWEPI (84% vs 41%, p < 0.001) and detected lipid-rich necrotic cores.
