[Overestimation of XXXX due to an increase in thallium uptake by the lung].

@entity1 @entity712 @entity308 @entity296 @entity384 @entity583
Thallium lung uptake (TL-uptake) was usually treated as background for myocardial image and increase of TL-uptake in exercise test was considered as marker of @entity308 . It was reported that marked increase of TL-uptake in @entity1 with @entity583 ( @entity583 ) corresponded to acute severe @entity712 . Here effect of TL-uptake on myocardial planar images was studied in 61 @entity1 with @entity583 . In acute phase anterior, LAO 30 degrees and LAO 60 degrees myocardial images were collected. In 29 cases of 61 cases 3 to 6 hours delayed images could be collected. Each myocardial images was divided to 3 division and both images were compared. In 5 of 6 @entity1 with marked increase of TL-uptake new defects were noted in anterior division of delayed images and in one case also in lateral division. In 7 @entity1 of 12 @entity1 with moderate increase of TL-uptake new defects were also noted in delayed images, i.e. 3 in anterior, 3 in inferior and one in apical division. It was concluded that over estimation of @entity296 due to marked increase of TL-uptake was often noted in @entity1 with @entity583 accompanying severe @entity384 . It became clear that delayed images were necessary to correctly estimate @entity296 in such case.
