Abstract

Purpose: This study describes a new 1-day protocol with Tc-99m tetrofosminthat requires only 100 minutes to obtain both stress and resting cardiac images by using a double-injection and subtraction method,Methods: This procedure was performed in 48 consecutive patients, Rest-rest double injections were performed in eight patients (five men, three women; mean age, 69 +/- 9.8 years) to evaluate count and image reproducibility (subprotocol A), and stress-rest and additional resting perfusion images (true rest) were done on a different day in 11 patients (five men, six women; mean age, 63 +/- 5.9 years) to confirm the validity of the new protocol (subprotocol B),Results: Image quality scores of the resting image were excellent (35 of 48, or 72.9%), good (7 of 48, or 14.6%), fair (3 of 48, or 6.3%), and poor (3 of 48, or 6.3%), The scintigraphic findings with the new protocol corresponded closely with those of angiography in 26 of 34 cases (76.5%), with a tendency for underestimation (in 5 of 34 cases, or 14.7%) rather than overestimation (in 3 of 34 cases, or 8.8%), In subprotocol A, count reproducibility between the two resting images was excellent (r = 0.95; P < 0.0001); andin subprotocol B, the early-rest images were concordant visually and quantitatively with the true rest images (r = 0.89, P < 0.0001),Conclusion: Although there are some limitations, this protocol can be usedas a routine stress-rest protocol.
