Insights
Cine magnetic resonance (MR) imaging identified diastolic filling issues in patients with thickened left ventricles (LV) that routine echocardiography missed. This suggests MR imaging is more sensitive for detecting diastolic dysfunction.
Area of Science:
- Cardiovascular Imaging
- Cardiac MRI
- Echocardiography
Background:
- Left ventricular (LV) diastolic dysfunction can be challenging to diagnose.
- Routine Doppler echocardiography may not always detect subtle diastolic abnormalities.
Purpose of the Study:
- To evaluate the sensitivity of cine magnetic resonance (MR) imaging in detecting left ventricular diastolic filling abnormalities.
- To compare cine MR imaging with Doppler echocardiography in patients with LV wall thickening and normal systolic function.
Main Methods:
- Cine magnetic resonance (MR) imaging of the heart was performed.
- Doppler echocardiography was used for routine assessment of cardiac function.
Main Results:
- Cine MR imaging detected left ventricular (LV) diastolic filling abnormalities.
- These abnormalities were present in patients with LV wall thickening but normal systolic and diastolic function by echocardiography.
Conclusions:
- Cine magnetic resonance (MR) imaging demonstrates higher sensitivity than routine Doppler echocardiography.
- Cine MR imaging may be a more effective tool for identifying early left ventricular diastolic dysfunction.
Abstract:
Cine magnetic resonance (MR) imaging of the heart detected evidence of left ventricular (LV) diastolic filling abnormality in patients with LV wall thickening but normal systolic function and normal diastolic function by routine Doppler echocardiography. Cine MR imaging may be more sensitive than routine echocardiography in detecting abnormalities of LV diastolic function.
