TY - JOUR T1 - SPECT Quality Improvement JF - Journal of Nuclear Medicine Technology JO - J. Nucl. Med. Technol. SP - 35 LP - 38 VL - 22 IS - 1 AU - Michael J. Feldkamp Y1 - 1994/03/01 UR - http://tech.snmjournals.org/content/22/1/35.abstract N2 - Objective: Obtaining quality SPECT data is a vital component of the total SPECT procedure. A patient study was undertaken to document the various causes of artifacts in order to pinpoint methods that will lead to an improvement in the quality of SPECT images. Methods: My institution’s laboratory monitored 1,000 stress/reinjection SPECT thallium patient studies to determine how to improve SPECT imaging. Results: Patient motion was identified as a major potential cause of imaging artifacts. Heart shift due to patient motion may result in false-positive studies. Conclusion: Large improvements in SPECT imaging quality can be obtained by adherence to a few meaningful technical points and maneuvers. ER -
