  • Title: Brain SPECT artifact in multidetector SPECT system.
    Author: Zhang JJ, Park CH, Kim SM.
    Journal: Clin Nucl Med; 1994 Sep; 19(9):789-91. PubMed ID: 7982313.
    Abstract:
    Stringent quality control cannot be overemphasized in performing SPECT. SPECT artifacts related to camera uniformity, center of rotation, and the patient's motion are well recognized. In this communication, another rare cause of a SPECT artifact related to a triad system is reported. A triple-headed SPECT system was accidentally equipped with two ultrahigh-resolution collimators and a general all-purpose collimator during a brain SPECT study, causing a false cerebral blood flow defect.
