Left Ventricular Function: Correlation of Quantitative Gated SPECT and MR Imaging over a Wide Range of Values

Q: What does this research mean for the field?

Quantitative gated SPECT correlates well with magnetic resonance imaging for assessing left ventricular ejection fraction (r=0.85), end-diastolic volume (r=0.94), and end-systolic volume (r=0.95). Novelty: ClaimNovelty.METHODOLOGICAL. Consensus alignment: ConsensusAlignment.NEUTRAL.

Key Result

Quantitative gated SPECT correlated well with magnetic resonance imaging for assessing left ventricular ejection fraction (r=0.85), end-diastolic volume (r=0.94), and end-systolic volume (r=0.95).

Correlation of left ventricular (LV) end-diastolic volume (LVEDV), end-systolic volume (LVESV), and ejection fraction (LVEF)surrogate

Quantitative gated SPECT shows strong correlation with MRI for assessing left ventricular volumes and ejection fraction.

Main Result

Effect estimate: r = 0.85 (LVEF), 0.94 (LVEDV), 0.95 (LVESV)

Abstract

In 21 patients, the authors compared results with quantitative gated single photon emission computed tomography (SPECT) to results with magnetic resonance imaging in the assessment of left ventricular (LV) end-diastolic volume (LVEDV), end-systolic volume (LVESV), and ejection fraction (LVEF). Between the two methods, correlations were good for LVEF (r = 0.85), LVEDV (r = 0.94), and LVESV (r = 0.95). Quantitative gated SPECT can help determine LVEF, LVEDV, and LVESV.
