Vascular-related imaging artifacts in the abdomen are similar to those in the chest and are listed in Table 26.1. The injection site might overlie the abdomen; it might appear focal (Fig. 26.1) or may be more linear if radiopharmaceutical is retained in catheter tubing or if extravasation occurred (Fig. 26.2). Care should be given to ensure that the injection site and the arms are moved away from the body to avoid subsequent processing artifacts (Chamarthy and Travin 2010; Gentili et al. 1994; Strauss et al. 2008). Except to qualify the diagnostic quality of the examination, reporting vascular system findings is generally not clinically warranted.
