Ht. Turoglu et al., LUNG-HEART RATIO IN STRESS THALLIUM MYOCARDIAL PERFUSION IMAGING IN PATIENTS WITH A HISTORY OF A PREVIOUS PNEUMONECTOMY, Clinical nuclear medicine, 21(10), 1996, pp. 783-785
Increased TI-201 lung-heart ratio after treadmill exercise or pharmaco
logic stress is an indicator of left ventricular dysfunction, After pn
eumonectomy, it is not reliable because of increased pulmonary circula
tion in the remaining lung. The authors present an example of normal s
tress TI-201 myocardial perfusion imaging with an increased lung-heart
ratio of TI-201 uptake.
