INTRODUCTION: Myocardial blood flow was evaluated with magnetic resonance (MR) perfusion in the patients with impaired glucose tolerance (IGT), and the existence of microvascular obstruction and risk for cardiac diseases were researched.In addition, the wall motion, wall mass (gram), and viability of the left ventricle, and the systolic function of both ventricles were evaluated.METHODS: Twenty patients with IGT, 16 patients with type 2 diabetes mellitus (DM) and 15 patients with normal MR findings were included in our study.

All patients were examined in the supine position using Birth Flower Name Necklace a body coil with 1.5 Tesla MR.Firstly, images B-TFE cine sequences to see the wall motions, calculate the wall mass and the left ventricular ejection fraction.

"Black blood" T2-weighted and STIR sequences were then taken to exclude other cardiac myocardial diseases.Basal, midventricular, and apical short-axis sequences were obtained by intravenous administration of 0.2 mmol/kg Gd-DTPA to evaluate first-pass perfusion.

And late opacification findings were obtained 10 minutes after the injection with the "inversion recovery GRE" sequence.RESULTS: When peak enhancement and accumulated enhancement in the first pass perfusion of myocardial tissue were investigated, the similarity was found in cases with IGT and type-2 DM.However, significant differences were found compared to the healthy control group.

In the first pass perfusion; When contrast agent arrival time and the peak of contrast agent increase in myocardial tissue were compared, no difference was observed between these groups.In addition, left and right ventricular systolic functions were similar between groups.DISCUSSION AND CONCLUSION: Flight Boards In the cases with IGT, myocardial microvascular circulation disorders can emerge in early phases without the presence of coronary artery disease.

In these kinds of cases, cardiac MRI can be an important choice.
