Hot spots observed on pulmonary perfusion imaging: a case report.

摘要

A case of hot spots observed on perfusion lung images is presented. This artifact is well known, however, it is rarely seen in our experience. Although this artifact can occur if a faulty injection technique is used, the artifact also may be caused by embolization of the MAA in the upper extremity venous blood after injection. This cause of the artifact is beyond the control of the nuclear medicine professional.
