“…Computed tomography evaluation of the canine abdomen has been described in a small number of studies that have included characterization of conditions of the upper and lower urinary tract, spleen, hepatic/portal venous abnormalities, pancreas, mesenteric/intrapelvic neoplasia, adrenal gland, and gastrointestinal tract . A recent study described a sedated contrast‐enhanced CT protocol in clinical canine patients .…”

Contrast-enhanced multi-detector computed tomography (CE-MDCT) is used routinely in evaluating human patients with acute abdominal symptoms. Contrast-enhanced ultrasound (CEUS) continues to be in its infancy as it relates to evaluation of the acute abdomen. The purpose of this study was to compare survey radiography, B-mode ultrasound, CEUS, and CE-MDCT findings in canine patients presenting with acute abdominal signs; with a focus on the ability to differentiate surgical from non-surgical conditions. Nineteen dogs were prospectively enrolled. Inclusion required a clinical diagnosis of acute abdominal signs and confirmed surgical or non-surgical causes for the clinical signs. Agreement for the majority of recorded imaging features was at least moderate. There was poor agreement in the identification of pneumoperitoneum and in the comparison of pancreatic lesion dimensions for B-mode vs. CEUS. The CT feature of fat stranding was detected in cases including, but not limited to, gastric neoplasia with perforation, pancreatitis, and small intestinal foreign body. Ultrasound underestimated the size and number of specific lesions when compared with CE-MDCT. Contrast-enhanced ultrasound was successful in detecting bowel and pancreatic perfusion deficits that CE-MDCT failed to identify. Accuracy for differentiation of surgical vs. non-surgical conditions was high for all modalities; 100%, 94%, and 94% for CE-MDCT, ultrasonography and survey radiography respectively. Findings indicated that CE-MDCT is an accurate screening test for differentiating surgical from non-surgical acute abdominal conditions in dogs. Focused CEUS following CE-MDCT or B-mode ultrasonography may be beneficial for identifying potentially significant hypoperfused lesions.

“…3 Reports describing CT evaluation of the canine abdomen have increased during the past decade. Applications include suspected disease of the upper and lower urinary tract, [5][6][7][8][9][10][11] spleen, 12,13 hepatic/portal venous system, [14][15][16][17][18][19][20][21][22][23][24][25][26] pancreas, [27][28][29] mesenteric/intrapelvic regions, 30,31 adrenal gland, [32][33][34] and gastrointestinal tract. 35,36 These reports primarily describe the use of anesthesia or heavy sedation during scan procedures in order to minimize motion artifacts that could result in nondiagnostic scans.…”

Canine patients with acute abdominal signs are often clinically unstable and need a rapid and accurate diagnosis. Contrast-enhanced multi-detector computed tomography (CT) is the current modality of choice for evaluating acute abdominal pain in people. We hypothesized that contrast-enhanced multi-detector CT 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 precontrast, arterial, and portal venous phases. Eight dogs were scanned awake and ten 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 higher than in the awake group but was within the normal reference range. Other laboratory and physiologic measures did not differ between awake and sedated groups. No IV contrast-related adverse reactions were seen. Median scan time for all patients was less than 10 min. Sixteen of 18 contrast-enhanced multi-detector CT scans were scored fair to excellent in diagnostic quality, with no statistical difference in diagnostic quality for awake vs. sedated patients. Causes for two poor quality diagnostic scans included severe beam hardening from previously administered barium contrast agent and severe motion artifacts. We conclude that dual-phase contrast-enhanced multi-detector CT is a feasible and safe technique for evaluating awake and minimally sedated dogs presenting with acute abdominal signs.

“…One case report used scintigraphy to quantify glomerular filtration rate in a dog presented for haematuria. Scintigraphy revealed subclinical renal insufficiency and thus surgery was not performed 16. To the authors’ knowledge, no other dog with ureterocoele in which scintigraphy was performed before surgery and specifically to assess individual kidney function has been described.…”

A 21-month-old entire female labrador retriever was presented for polyuria, pollakiuria, haematuria and intermittent urinary incontinence. Clinical signs were absent during antibiotic treatment but reoccurred shortly after completion of a treatment course. Investigations detected bilaterally dilated ureters, right renal hypoplasia, left extramural ectopic ureter and right intramural ectopic ureter forming an ureterocoele. Blood tests revealed moderate renal azotaemia. 99mTc-DMSA (technetium-99m-dimercaptosuccinic acid) scintigraphy was used to quantify individual kidney function to carefully consider nephrectomy. The right kidney contributed to less than 2 per cent of the total kidney function. Individual kidney function assessed by 99mTc-DMSA scintigraphy was compared with CT-based renal parenchyma volume as an equivalent to kidney function. In this case both diagnostic imaging techniques resulted in similar individual kidney function percentages. A right-sided nephroureterectomy and a left-sided neoureterocystostomy were performed. Surgical treatment successfully resolved the clinical signs. After surgery the dog’s chronic kidney disease remained stable at International Renal Interest Society chronic kidney disease stage 3.
