Diagnostic Value of Histopathology, Radiography and Computed Tomography for Diagnoses of Canine Osteo-Arthritis
Osteoarthritis is a common orthopedic problem in the small animals patients. In most cases, the degenerative changes in the joint are secondary to some predisposing cause. The objective of this case study was to assess Diagnostic Value of Histopathology Radiography and Computed Tomography for Diagnosis of Canine Osteoarthritis The study was conducted in Police Dogs Administration (Ministry of Interior, X-ray Department), included Female German Shepherd dog which diagnosed radiographically for hip dysplasia and osteoarthritis. Using conventional radiography and CT images It concluded that conventional radiography is the most common method used to evaluate osteoarthritis, there has been an increase in the application of other imaging technologies (CT) during the past several years. These modalities and thehistopathology can provide the clinician with additional information that can improve case management.
Study of Mastoid Air Cells Diseases using Spiral CT
This study aimed to study the mastoid air cells diseases and their complications using spiral CT, it was conducted in Alfaisal Specialized hospital and Ibn Elhaitham Diagnostic center in the period between September 2012 to January 2013, Hundred patients of different ages and different genders who were suspected of having mastoid air cells pathologies underwent Spiral CT scan of their temporal bones using 4MDSCT (Toshiba medical system),then the scanning was done with collimation of (1-2) mm, 2mm slice thickenings ,120 Kvp ,160 MA and 1 second rotation time. after that The results were confirmed that the mastoid air cells diseases were very common and they had serious complications, (The diseases of mastoditis and mastoditis with CSOM had higher frequency (83 pts among 100 pts).and they had pathological changes of anatomical structures of the temporal bones which contains organs of hearing and balance). Finally the study has found that Spiral CT scan is an effective imaging modality in studying of mastoid air cells diseases and their complications. Also it was more affective to explain the complex anatomical structures of the temporal bones and to know the pathological changes within it
