TY - JOUR T1 - A Bizarre Ring Artifact on SPECT/CT Images JF - Journal of Nuclear Medicine Technology JO - J. Nucl. Med. Technol. SP - 119 LP - 120 DO - 10.2967/jnmt.116.189365 VL - 45 IS - 2 AU - Sajid Bashir AU - Muhammad Shahbaz AU - Dilber Iqbal Y1 - 2017/06/01 UR - http://tech.snmjournals.org/content/45/2/119.abstract N2 - We encountered a round artifact on images obtained with our SPECT/CT system: a small dark spot surrounded by a broad light ring. The artifact was due to a problem with the SPECT portion of the hybrid system and was successfully removed through servicing of the system. This case report describes this scanner-based artifact, which, to our knowledge, has not previously been reported in the literature. ER -
