Discussion
Chest
There is intense, ill-defi ned, and variable activity across the top of the fi eld-of-view during the stress acquisition (b); this is not seen on the rest acquisition (a). The patient was too weak to keep his arms above his head, and the technologist held them in place throughout the acquisition (a, b). The activity is related to extravasa­tion at the injection site which periodically slipped into the fi eld-of-view as his arms moved (b). There was no signifi cant detrimental effect from this “hot” artifact on the processed images (c, d).
However, motion affected the quality of the examination and the confi dence in the interpretation. Both sets of images are compromised by motion artifact (a, b, c, d). There is minimal motion on the rest data (a) but marked motion on the stress data (b). Both original and motion-corrected stress data sets were reviewed with the rest images; there was no signifi cant change in the appearance of the apparent small, severe, reversible apical defect. During a follow-up examination one year later, the patient was able to cooperate, and the examination was normal.
Abdomen
There is a “beating gallbladder” due to motion on the stress images (b). There is a “hot” stomach at rest (a) and a “cold” stomach at stress (b), consistent with variable duodenogastric refl ux.

Discussion
Chest
The chest is normal. Heart size is at the upper level of normal for a male; there is no change during over serial examinations. His vasodilator nuclear stress tests have been normal, with LVEF ranging from 62 to 68 %. The current processed images and gated images are shown in Fig. 29.9d, e.
Abdomen
Minimal to no ascites is apparent on serial contemporaneous CT scans (not shown). Note a small liver (a, b, c). A “small” gallbladder is intermittently visualized: it is seen on the current (a) and original (c) serial examinations, but is not identifi ed on the one in-between (b). This pattern is suggestive of chronic gallbladder disease. Review of previous examinations is an important step in interpretation.
Note an enlarged spleen (a, b, c), consistent with underlying cirrhosis. On the
current examination, there is faint gastric activity which might signal gastropathy.
