Tc-99m ECD 뇌혈류 SPECT 시행시 부적절한 영상획득 모수에 의한 인공산물

An Artifact Caused by Using the Inadequate Acquisition Parameter in Tc-99m ECD Brain Perfusion SPECT

Although artifacts in tomographic imaging can arise from a number of sources, this case presents an artifact caused by using inadequate acquisition parameters which do not match the collimator with which a camera equipped in Tc-99m ECD brain SPECT. Whenever the collimator in tomographic studies is changed, we should take care to use suitable parameters of acquisition protocol according to the collimator with which a camera is fitted. Other ways to prevent an error of this type is to use a point source.
