There is a rod-like area of apparent increased activity on the SPECT maximum-intensity projection (MIP) images (Fig. 1). The transaxial filtered-back-projection SPECT images show a corresponding linear streak of increased activity (Fig. 2).
What would you do next?
[pagebreak] Examination of the raw projection images (Fig. 3) shows absent data for the last approximately 20 frames of the acquisition. Focusing on just the last few frames with data (Fig. 4), the data collapse to a single point before disappearing.
What might be the cause?
