Key result
The non-imaging nuclear probe accurately measured left ventricular ejection fraction compared to a gammacamera, detecting LVEF reductions during exercise (52% to 28%) and pacing in CAD patients.

Can a non-imaging nuclear probe accurately assess left ventricular function during controlled interventions compared to a digital gammacamera?
The non-imaging nuclear probe is a portable and effective tool for assessing beat-to-beat left ventricular function during clinical interventions.
Lahiri et al. (1984) conducted an observational in Coronary artery disease. Nuclear probe vs. Digital gammacamera was evaluated on Left ventricular ejection fraction. The non-imaging nuclear probe accurately measured left ventricular ejection fraction compared to a gammacamera, detecting LVEF reductions during exercise (52% to 28%) and pacing in CAD patients.
