Implication

Diagnostic study demonstrates rapid serial tracking of cardiovascular blood flow in humans, indicating superior temporal resolution and lower radiation compared to conventional scanners.

Key Points

To evaluate the clinical application and dynamic vascular imaging capabilities of the gamma-ray scintillation camera in human patients.
Administered intravenous bolus injections of technetium-99m pertechnetate (5 to 10 mCi) via the antecubital vein using a transiently inflated blood pressure cuff release technique.
Acquired continuous serial five-second exposures across a 9-inch useful field of view using a maneuverable scintillation camera head with three degrees of freedom.
The gamma camera visualized dynamic targets in one-fifth to one-twentieth the time required by conventional automatic scanners, permitting lower radioactive doses and reduced total-body radiation exposure (approximately 130 mrad per 10 mCi).
Serial five-second thoracic imaging following a 7 mCi bolus mapped transit from the vena cava to the right heart at 0–5 seconds, the pulmonary circulation at 5–9 seconds, and systemic distribution across both cardiac sides and aorta at 10–14 seconds.
