متن کاملThallium-201 for myocardial imaging. Relation of thallium-201 to regional myocardial perfusion.
Following intravenous administration, the myocardial concentration of tracer thallium-201, potassium-43, and rubidium-81 were determined in mice; thallium was present in the greatest concentration in the myocardium (2.08% compared 1.25% for potassium and 1.15% for rubidium at 10 minutes). The regional myocardial distribution of thallium-201 was determined in dogs under conditions of normal flow...
متن کاملRelationship between 24-hour blood pressure pattern and left ventricular structure and function in hypertensive Nigerians.
OBJECTIVE Blood pressure variation throughout the day is known to have cardiovascular consequences. Left ventricular (LV) mass is more closely related to 24-hour blood pressure than casual blood pressure. Daytime blood pressure expectedly is higher than that of nighttime under normal circumstances. The effect of 24-hour blood pressure pattern on the left ventricular structure and function has n...
متن کاملQuantitative thallium-201 myocardial imaging in assessing right ventricular pressure in patients with congenital heart defects.
Thallium-201 myocardial scintigraphy was performed in patients with congenital heart defects to determine whether, by quantification of right ventricular isotope uptake, one could assess the degree of right ventricular hypertrophy and so predict the level of right ventricular pressure. A total of 24 patients ranging in age from 7 months to 30 years was studied; 18 were studied before corrective...
