PEIX, Amalia T. et al. Myocardial perfusion scintigraphy with technetium 99m-MIBI in the diagnosis of coronary artery disease in women. Rev cubana med [online]. 2006, vol.45, n.2, pp. 0-0. ISSN 1561-302X.

The results of technetium 99m - methoxy-isobutyl-isonitril scintigraphy in a one-day protocol: rest - physical or combined stress (bicycle plus endovenoous dipiridamole) were compared with those of coronary angiography in 20 women referred for the evaluation of precordial pain and of the usefulness of myocardial perfusion scintigraphy. The uptake of the radiodrug under stress and at rest varied from 93 ± 9 to 94 ± 7 % in the 204 segments with normal uptake under stress, from 67 ± 9 to 75 ± 17 % in the 89 with moderate reduction, and from 33 ± 9 to 64 ± 28 % in the 27 with severe reduction. The qualitative and quantitative uptake analyses coincided in 18 patients. The perfusion scintigraphy and the angiography agreed in 70 % of the patients. It was concluded that the myocardial perfusion scintigraphy with technetium 99-MIBI contributes to the diagnosis of the coronary artery disease in women.
