Major upward creep of the heart during exercise thallium-201 myocardial SPECT in a patient with chronic obstructive pulmonary disease.
We report on a patient in whom we observed an unusually important upward creep of the heart on postexercise 201TI tomographic acquisition. When uncorrected, this led to reconstruction of grossly abnormal tomograms, which were normal after correction of upward creep of the heart. This phenomenon may be related to the patient's history of chronic obstructive pulmonary disease. Special attention should be given to upward creep artifact in such pulmonary diseases.
