Gated Heart Study

Indications:  

• Assessment of volume, wall motion, and function of LV.

Principle:

• The patient's red blood cells are labelled with a radiotracer. Imaging of the heart is synchronised with the patient's ECG, allowing assessment of wall motion and cardiac function.

Preparation and Procedure:

• No preparation required.

• The camera is centred over the cardiac blood pool. Scan time is approximately 30 minutes, the entire procedure takes approximately 1 hour.

Comments:

• Gated heart imaging is a well-established, relatively inexpensive and accurate method for evaluating cardiac size, wall motion and function.

• The test should not be used for detecting intra-atrial or intra-ventricular masses such as clots or tumours, direct evaluation of valve motion, or estimating myocardial thickness. Cardiac Echo Studies are the procedure of choice for assessing these parameters.
