Takotsubo syndrome is an acute clinical condition mimicking acute myocardial infarction. Nuclear cardiology imaging obtains information that is close to the pathology of Takotsubo syndrome and is widely used in clinical practice to accumulate evidence. Regional semi-quantitative analysis revealed that the metabolic abnormalities were exclusively in the apical area, which was one of the features of Takotsubo syndrome. 123I-MIBG has the ability to reveal apical sympathetic nerve abnormalities, which often are prolonged. This article describes both the latest findings of Takotsubo syndrome as well as the characteristics of the disease condition and the practical use of a nuclear cardiology technique.
