¹⁸F-fluorodeoxyglucose coincidence imaging diagnosis the myocardial viability after myocardial infarct

Objective: To evaluate the value of (¹⁸F-fluorodeoxyglucose, ¹⁸F-FDG)coincidence imaging and (^99mTc-sestamibi, ^99mTc-MIBI)myocardial perfusion imaging diagnosis the myocardial viability after myocardial infarct. Methods: 24 cases myocardial infarcts patients undertaking angiography, ^99mTc- MIBI stress and rest myocardial perfusion imaging, ¹⁸F-FDG coincidence metabolism imaging (fasting- glucose stress one day imaging) with single phone emission computer tomography. Results: 27 out of 49 ^99mTc-MIBI reduced myocardial perfusion myocardial segments mismatch fasting and glucose stress ¹⁸F-FDG uptake suggesting the viable myocardial. 22 segments with reduced myocardial perfusion match fasting and glucose stress ¹⁸F-FDG uptake suggesting no viable myocardial. Fasting imaging viable myocardial can uptake less ¹⁸F-FDG but image well, glucose stress imaging viable myocardial can uptake more ¹⁸F-FDG and improved the image quality. Conclusions: Fasting and glucose stress can show myocardial viability, imaging quality was less well in fasting and improved in glucose stress. (authors)
