Implication

Supports gated NMR feasibility for noninvasive cardiac imaging in ischemic disease; leaves open validation versus other modalities.

Key Points

The study aimed to evaluate the efficacy of gated nuclear magnetic resonance (NMR) imaging in diagnosing cardiac structure abnormalities in patients with chronic ischemic heart disease.
Gated NMR imaging performed on eight normal subjects and ten patients with chronic myocardial infarctions.
Multisectional imaging using the spin-echo technique, capturing most of the left ventricle within 5 to 12 minutes.
No contrast medium was utilized, allowing for clear visualization of internal cardiac structures.
Internal cardiac structures were successfully defined without contrast medium, showing trabeculations and papillary muscles.
NMR imaging effectively depicted postinfarctional changes including wall thinning, aneurysms, and mural thrombi.
High signal intensity was correlated with regions of akinesis or dyskinesis near infarcts, indicating blood stasis.

Structured PICO

Is gated nuclear magnetic resonance (NMR) imaging feasible for defining cardiac anatomy and left ventricular abnormalities in patients with chronic ischemic heart disease?

Population

18 subjects (8 normal subjects and 10 patients with chronic myocardial infarctions)

Intervention

Gated nuclear magnetic resonance (NMR) imaging at a magnetic field strength of 3.5 kGauss using spin-echo technique

Outcome

Feasibility of imaging the human heart and demonstrating left ventricular abnormalities associated with chronic myocardial infarctionsurrogate

Gated NMR is a feasible, completely noninvasive technique for imaging the human heart and identifying structural abnormalities in chronic ischemic heart disease.
