Evaluation of pelvic diaphragm muscles in dogs merits clinical attention because of the anatomical importance and their involvement in perineal hernia. This study aimed to evaluate the normal pelvic diaphragm muscles (levator ani and coccygeus muscles) using the computed tomography (CT) scan. For this purpose, 10 male and 10 female clinically normal, adult intact mixed-breed dogs weighing 15.00 to 20.00 kg were selected randomly. All animals underwent CT examination under general anesthesia and positioned in sternal recumbency. All the CT images were taken and reconstructed with a same protocol. The measurements of the pelvic diaphragm muscles were performed based on the presented guideline to the observer. The results were presented descriptively. The mean lengths of the coccygeus muscle in CT images were evaluated 4.60 cm for males and 4.30 cm for females. The mean lengths of levator ani muscle in CT images were measured 4.90 cm in males and 4.50 cm in females. In conclusion, the results of the present study can be beneficial to clinicians and researchers for further evaluation of the supporting muscles in pelvic cavity and underlying anatomical changes in perineal hernia in dogs.

Prostate gland can be structurally evaluated by computed tomography (CT) with taking advantages of tomographic feature and post-contrast parenchymal changes. The current examination initiated to determine association between computed tomographic and cytological results in evaluation of canine prostate. Thirty mature male dogs were included and under gone by both CT and fine needle sampling of prostate. The cytology and CT examination results showed 18/30 (60.00%) and 15/30 (50.00%) normal prostate, 5/30 (16.66%) and 4/30 (13.33%) prostatitis and 7/30 (23.33%) and 11/30 (36.66%) benign prostatic hyperplasia, respectively. Moderate agreement has been found between cytology and final diagnosis based on pre-contrast CT images, however fair agreement was existed between cytological diagnosis and final CT interpretation according to post-contrast and both pre- and post- contrast CT series. Additionally, the internal iliac lymph node length showed statistically significant difference in prostatitis compared to normal and benign hyperplastic prostates in this study. In conclusion, the fair and moderate associations between cytology and final diagnosis based on CT images should be considered and they can be used in further investigations and clinical examinations. Also, using internal iliac lymph node length to differentiate prostatitis with normal and benign hyperplastic prostates can be used efficiently in diagnosis to choose the best method of management and have a proper follow up and prognosis.

The objective of this study was to evaluate the pituitary gland dimensions due to age and weight using computed tomography (CT) in dogs and cats. The CT images of pituitary gland were assessed in 11 client-owned dogs (six males and five females; age range, 1 to 9 years) and 15 client-owned cats (eight males and seven females; age range, 1 to 14 years) with no evidence of pituitary diseases. The length, height, width and volume of the pituitary gland were measured in sagittal and transverse planes. Mean pituitary length, width, height and volume (± standard deviation: SD) were respectively 4.96 (± 0.69 mm), 3.62 (± 0.64 mm), 2.62 (± 0.05 mm) and 26.19 (± 7.99 mm3) in cats and were 7.00 (± 2.14 mm), 4.80 (± 1.20 mm), 3.80 (± 0.70 mm) and 77.53 (± 51.64 mm3) in dogs, respectively. Mean pituitary height-to-brain ratio (P:B ratio), (± SD) in cats and dogs was 0.28 (± 0.05) and 0.21 (± 0.03), respectively and mean percent of pituitary volume to brain volume (± SD) in cats and dogs was 0.10 (± 0.05) and 0.10 (± 0.07), respectively. There was no significant correlation between the size of pituitary gland and age, weight and body condition score (BCS) in dogs, however in cats, significant difference was found between height of pituitary gland and weight and BCS, pituitary width and weight and P:B ratio and BCS. These findings could be useful to identify abnormal pituitary gland enlargement in CT images. To be more accurate in the assessments, further studies are required.

The pomegranate seed oil (PSO), containing 17-α-estradiol, is one of the newly found phytosterols with synergistic health effects on estrogen related physiological conditions. Herein, PSO was assessed for its potential improving effects on bone characteristics in a rat model of menopausal syndrome. Three month old non-pregnant female Wistar rats (n = 30) were either sham-operated (SHAM) or ovariectomized (OVX), each divided into two further groups receiving 0.1 mL PSO or the same volume of paraffin oil as placebo. Before the operation and 67 days after it, multi-detector computed tomography (MDCT) scanning was performed with the identical setup option for the scanner to measure the bone mineral density (BMD) in body of 12th thoracic vertebra, 1st to 6th lumbar vertebra and sacrum. This study revealed that bone density of 1st, 3rd, 5th, 6th and sacrum body were significantly different between OVX and SHAM groups during the study period. In conclusion, PSO during 67 days study could not completely prevent the osteoporotic effects caused by ovariectomy in vertebral column of rats.
