201Tl myocardial perfusion SPET: XXXX alone or combined with dynamic exercise.

@entity1 @entity859 @entity1009 @entity299 @entity453
201Tl myocardial perfusion single photon emission tomography (SPET) with pharmacological coronary vasodilatation using @entity859 is now often used in the investigation of a @entity1 with @entity299 ( @entity299 ). In this study, we present data from two groups of @entity1 . Group A (n = 40) experienced 201Tl SPET with @entity859 only as the pharmacological stress test, using an infusion rate of 140 micrograms kg-1 @entity1009 . Group B @entity1 (n = 50) had the same test combined with low-level dynamic exercise. The side effects were noted for both groups and 201Tl SPET studies were acquired for stress and redistribution images. There was a lesser degree of non-cardiac side effects in @entity1 of group B. There was a significant difference in the haemodynamic parameters between the two groups. There was no significant difference in overall sensitivity (87% versus 90%) and specificity (84% versus 88%) in the detection of @entity299 between the two groups. In conclusion, addition of low-level dynamic exercise with @entity859 is to be preferred to @entity859 infusion alone, as this protocol is better tolerated and may enhance the detection of right @entity453 (sensitivity = 82% versus 90%, n.s.).
