简要总结
Use of MRI and DWI to diagnose cardiac scarring after heart attack.
详细描述
To discover new information about MRI (magnetic resonance imaging) called DWI (diffusion weighted imaging) and its ability to diagnose cardiac scarring.
CMR-DE (cardiac MR with delayed contrast enhancement) evaluates if there has been scarring in the heart muscle following a heart attack.
Subjects are injected with a contrast medication that makes the scarring visible if present. To prove the efficacy of DWI (diffusion weighted imaging) to provide the same images that CMR-DE (cardiac magnetic resonance with delayed contrast enhancement) provides.

研究组 & 干预措施
Diffusion Weighted Imaging with MRI scans
Subjects will undergo a MRI (magnetic resonance imaging) scan where DWI (diffusion weighted imaging) will be performed. Subjects will not receive contrast during this sequence, but will receive contrast as standard MRI protocol.
干预措施: Diffusion Weighted Imaging with MRI scans (Procedure)
结局指标
主要结局
presence and apparent diffusion coefficient (ADC) quantification of scar on (DWI) diffusion weighted image
时间窗: single occurance
Confirm the efficacy of diffusion weighted imaging in providing imaging that shows cardiac scarring without the injection of contrast.
