          Abstract

          We present the challenges in performing the stress test and acquisition of images in myocardial scintigraphy in a 54-year-old female patient with dextrocardia. Dextrocardia and situs inversus were documented on prior investigations including a chest roentgenogram and sonography.

          Artifacts and pitfalls in myocardial perfusion imaging.

          Myocardial perfusion imaging (MPI) is an important imaging modality in the management of patients with cardiovascular disease. MPI plays a key role in diagnosing cardiovascular disease, establishing prognosis, assessing the effectiveness of therapy, and evaluating viability. However, MPI is a complex process, subject to a variety of artifacts and pitfalls, which may limit its clinical utility. These factors may be related to the patient (including unique aspects of the patient's heart), the nuclear medicine equipment, or the actions of the technologist. After reviewing this article, the reader should be familiar with the causes and the effects of these potential artifacts and pitfalls. The reader should develop an understanding of steps to limit these factors, actions to correct them if they do arise and, when necessary, how to incorporate their influence into the interpretation of the study.

            Dextrocardia: practical clinical points and comments on terminology.

            Dextrocardia is defined by the authors as a right-sided heart with a base-apex axis directed rightward, resulting from a variation in cardiac development, and not used as a general term indicating any heart in the right chest. Dextrocardia occurs in approximately 0.01% of live births and can be discovered in various clinical settings and at various patient ages. The authors review their experience with dextrocardia, discuss useful clinical points that aid in evaluating complex anatomy, recount the history of dextrocardia terminology, and note the current inconsistent nomenclature.
