MALE STUDENT: Um, Professor Harrison? Then how come in my periodic table here element 43 is “Tc”--that's technetium, right? MALE PROFESSOR: OK, let me add that …Actually, uh, that's the point I’m coming to.Hardly anyone believed that Tacke had discovered a new element.X-ray spe...
A review considering technetium-99m- labeled macro-aggregates of albumin. Ann Nucl Med 2009; 23:1-16.Z觟phel K, Bacher-Stier C, Pinkert J, et al. Ventilation/perfusion lung scintigraphy: what is still needed? A review considering technetium -99m -labeled macro -aggregates of albumin [...
Out of a total (n) of 119 patients, true positive (TP) cases were 62, true negative (TN) 17, false positive (FP) 22 and false negative (FN) 18. Conclusions: ETT is an acceptably sensitive but non-specific test for evaluating myocardial ischaemia, with adequate PPV but low NPV, when...
A radiochemical, usually technetium 99m pertechnetate, is administered via the rectum and first accumulates in the liver in normal animals. In dogs with portosystemic shunts the distribution of activity is altered as the radiochemical bypasses the liver and reaches the heart first. Although this ...
Ventilation/perfusion lung scintigraphy: what is still needed? A review considering technetium-99m-labeled macro-aggregates of albumin Lung perfusion scintigraphy (LPS) with technetium-99m-labeled macro-aggregates of albumin (Tc-99m-MAA) is well established in the diagnostic of pulmonary e......
