“…Recently, there is an increase in the use of computed tomography (CT) of the body cavities as an important and useful imaging modality in veterinary medicine as it can provide high-detail images of the thorax and abdomen (Samii et al 1998). Computed tomography (CT) is a most valuable technique used for the diagnosis of abdominal diseases and has become the imaging method of choice for the abdomen in the human medicine (El Sherif et al 1999;Novelline et al 1999;Ibrahim et al 2019).…”

The aim of this work is to throw more light on using some recent techniques as ultrasound, computed tomography (CT), and contrast radiography in examination of the kidney of Balady rabbit. The current work was carried out on 23adult healthy Balady rabbits. Topographical, morphometrical and radiographical examination on kidneys were occurred. Ultrasonographically, the animal was examined in both dorsal and lateral recumbency. Both kidneys were scanned in longitudinal and transverse planes. The different ultrasonographic measurements of both kidneyswere recorded.The rabbit was positioned in ventral recumbency and CT images were taken without contrast medium using multi-slices CT system. The right kidney was slightly anterior to the level of left one by its length. The right lobe of liver separated the right kidney from the stomach cranially. The left kidney was separated from the stomach and spleen with the ascending duodenum and jejunum. By contrast radiographs, both kidneys appeared clearly as dense soft tissues with distinct borders against the neighboring vertebrae and ribs. In the longitudinal ultrasonographic scanning plane, the medulla revealed anechoic nearly circular areas represented the peri-pelvic columns which separated by hyperechoic secondary septa. The main pelvic septum appeared hyperechoic. We could easily distinguish between the cortex and medulla in both longitudinal and transverse scanning plane. Therefore, we hope to contribute to clinic and histopathological diagnosis of kidney diseases.

Helical Computed Tomography - Anatomy of the Cat Abdomen

Computed tomography (CT) is a most valuable technique for the diagnosis of abdominal disorders. In veterinary medicine, x-ray and ultrasound are the imaging modalities of choice for the abdomen, but CT can provide information that cannot be obtained by other means. One mature, female, domestic cat, 4 kg weight was used for this study. The cat was clinically healthy, with no abnormal findings at hematological and biochemical analysis. It was premedicated with 20 µg/kg medetomidine and 0.3mg/kg butorphanol IM. For induction of anesthesia, 3 to 5 mg/kg propofol was administered IV. Anesthesia was maintained with a mixture of isoflurane and oxygen. The patient was positioned in sternal recumbency. CT scans were performed with a helical CT scanner Hi Speed CT/e Dual; General Electric. Technical factors were 120 kVp and 50 mA settings, with 1 rotation/s. All sections were imaged with soft-tissue window. CT scans were performed after IV injection of iodinated contrast medium, iopamidol, 2 mL/kg. The images are presented in progression from the 8th thoracic vertebra to the level of the pelvic inlet. Identifiable anatomical structures are labelled on the CT images. The stomach is left-sided with the gastric folds less numerous and thinner than those in the dogs. The normal small intestine contains less gas in cats. The feline cecum is very short. The liver showed a low attenuation with the mediastinum-vascular window settings, allowing better visualisation of the hepatic lobes and interlobular fissures. The gallbladder and bile ducts were also better visualised. CT imaging studies can provide additional information in patients with radiographic and ultrasonographic patterns of abdominal disorders, as a specialised imaging method, a useful preoperative technique and a precise staging tool. CT improves the image quality further and allows better timing of vascular phases. Helical CT angiography enables visualization of contrast-enhanced abdominal vessels using only a peripheral venous injection of iodinated contrast medium.
