Anatomical MRI is appropriate for the interpretation of soft tissue findings in the retroperitoneal part of the pelvic cavity. The aim of the current study was to use rabbits as an imaging model to optimize MRI protocols for the investigation of bulbourethral glands. The research was conducted on twelve clinically healthy, sexually mature male rabbits, eight months of age (New Zealand White), weighing 2.8 kg to 3.2 kg. Tunnel MRI equipment was used. The transverse MRI in the T2-weighted sequence obtained detailed images that were of higher anatomical contrast than those in T1-weighted sequences. The hyperintensity of the glandular findings at T2, compared to the adjacent soft tissues, was due to the content of secretory fluids. The quality of the anatomical tissue contrast has not shown much dependence on the choice of the sequence in dorsal MRI. The sagittal visualization of the rabbit bulbourethral glands corresponded to the localization of the research plane toward a median plane. The imaging results could be used as a morphological base for clinical practice and reproduction.

“…Diagnostic imaging methods such as CT and MRI provide detailed information about the identification, localization and extent of the pathology, but general anesthesia is required to ensure patient immobility while applying these imaging methods [14]. In the presented case, considering the general condition of the patient, the extent of the pathology and the technical conditions advanced diagnostic methods such as CT and MRI were not used.…”

A newborn German Shepherd breed male puppy was presented with the complaint that some organs were formed outside the chest and abdomen. The rhythmic movements of the swelling under the chest pointed out the heart and the swelling under the abdomen was covered with a membrane. On the lateral radiograph of body, sternal agenesis, extra–thoracic location of the heart, and normal diaphragmatic border were seen, while the swelling in the abdomen was thought to be liver. During the diagnostic steps, the puppy died, and necropsy was performed. At necropsy, it was observed that the heart wrapped with the pericardium was placed extra–thoracically (thoracic ectopia cordis) due to sternal agenesis, and the liver was partially located extra–abdominally (ectopia hepatica) due to fissura abdominalis, which was surrounded by the peritoneum. Both radiological and necropsy findings revealed that there was no rib structure after the costochondral joints. Diaphragm was present, and there was no abnormality in the other intrathoracic and intraabdominal organs. Here, it is aimed to report thoracic ectopia cordis, sternal agenesis, ectopia hepatica and fissura abdominalis in a German Shepherd puppy with milder incomplete pentalogy of Cantrell, and to present the radiological and necropsy findings of the anomaly.

“…The most recent database search was performed on 4 January 2024. The references of several other broadly scoped veterinary MRI review articles by Boss [18], Greco [19], Hecht [20], LeBlanc [21], and Vite [22] were also examined for potential data sources. The search was supplemented by entering the digital object identifier for each record returned during the initial database queries into the 'citationchaser' freeware tool and performing forward and backward citation chasing [23].…”

Magnetic resonance imaging (MRI) is used pervasively in veterinary practice for the antemortem diagnosis of intracranial tumors. Here, we provide an illustrated summary of the published MRI features of primary and secondary intracranial tumors of dogs and cats, following PRISMA scoping review guidelines. The PubMed and Web of Science databases were searched for relevant records, and input from stakeholders was solicited to select data for extraction. Sixty-seven studies of moderate to low-level evidence quality describing the MRI features of pathologically confirmed canine and feline brain tumors met inclusion criteria. Considerable variability in data inclusion and reporting, as well as low case numbers, prohibited comparative data analyses. Available data support a holistic MRI approach incorporating lesion number, location within the brain, shape, intrinsic signal appearances on multiparametric sequences, patterns of contrast enhancement, and associated secondary changes in the brain to prioritize differential imaging diagnoses, and often allows for accurate presumptive diagnosis of common intracranial tumors. Quantitative MRI techniques show promise for improving discrimination of neoplastic from non-neoplastic brain lesions, as well as differentiating brain tumor types and grades, but sample size limitations will likely remain a significant practical obstacle to the design of robustly powered radiomic studies. For many brain tumor variants, particularly in cats, there remains a need for standardized studies that correlate clinicopathologic and neuroimaging data.
