BACKGROUND To date, stress cardiovascular magnetic resonance (CMR) has relied on pharmacologic agents, and therefore lacked the physiologic information available only with exercise stress. METHODS 43 patients age 25 to 81 years underwent a treadmill stress test incorporating both Tc99m SPECT and CMR. After rest Tc99m SPECT imaging, patients underwent resting cine CMR. Patients then underwent ...

introduction: the purpose of this study is to assess the integrated role of scintigraphy by tc99m mibi in diagnosis of parathyroid adenoma and its impacts on the myocardium, and to evaluate whether myocardium perfusion gated spect study could be a complementary routine workup for patient with positive parathyroid adenoma on tc99m mibi parathyroid scan. methods: rest myocardium perfusion gated s...

introduction: we aimed to investigate of effect of left bundle branch block (lbbb) on perfusion and functional parameters in dipyridamole tc99m-mibi gated myocardial perfusion spect which may be helpful in interpretation of myocardial perfusion imaging. methods: we studied 70 patients with low pre-test probability of coronary artery disease in two groups:  35 patients with lbbb and  35 subjects...

Using the stack-foil activation technique, excitation functions were measured for (p, x) reactions on Monat target. The target was irradiated with a proton beam of 17 MeV kinetic energy. Along medically important radioisotopes Mo99/Tc99m we studied other long-lived radio-impurities produced in Cross sections all from Monat(p,x) are compared available literature data, which show good agreement.
