Abstract:
An ectopically located gallbladder is rare and unusual. In this study, we described a case of a 52-year-old woman who underwent SPECT-myocardial perfusion imaging because of exertional dyspnea and chest tightness. The rest sinograms reveal 2 substantially increased tracer uptakes in the right chest. Subsequently, a SPECT/CT scan was performed to clarify the indeterminate findings on the SPECT-myocardial perfusion imaging. The coregistered SPECT/CT images depict intense focal activity in the right chest, which corresponds to the gallbladder on the CT scan, thus explaining the peculiar ectopic gallbladder finding.

Transthoracic Echocardiography (TTE)
TTE is the most common type of echocardiogram which involves placing a transducer on the patient's chest, emitting sound waves to create heart images. TTE is invaluable for evaluating the heart's size, structure, and motion, making it particularly useful for...
