Abstract	Canine patients with acute abdominal signs are often clinically unstable and need a rapid and accurate diagnosis. Contrast-enhanced multi-detector computed tomography (CE-MDCT) is the current modality of choice for evaluating acute abdominal pain in people. In phase one of this study we hypothesized that CE-MDCT would be a feasible and safe technique for use in awake and lightly sedated dogs with acute abdominal signs. Eighteen client-owned dogs were enrolled, all presenting with acute abdominal signs. Dogs were scanned using a dual-phase protocol that included pre-contrast, arterial and portal venous phases. Eight dogs were scanned awake and 10 were given light sedation as chosen by the primary care clinician. Two observers who were unaware of clinical findings and sedation status scored image quality for each scan by consensus opinion. Mean serum creatinine in the sedated group was significantly higher than in the awake group but was within the normal reference range for dogs. Other laboratory and physiologic measures did not differ between awake and sedated groups. No intravenous contrast-related adverse reactions were seen in any of the dogs. Median scan time for all patients was less than 10 minutes. Sixteen of 18 CE-MDCT scans were scored fair to excellent in diagnostic quality, with no statistical difference in diagnostic quality for awake versus sedated patients. The two poor quality diagnostic scans were attributed to severe beam hardening from previously administered barium contrast agent and severe motion artifacts. The results of this study suggest that dual-phase CE-MDCT is a feasible and safe technique for evaluating awake and minimally sedated dogs presenting with acute abdominal signs.
