The purpose of this study was to determine the diagnostic value of magnetic resonance imaging (MRI) and computed tomography (CT) in oral masses of dogs. Nineteen dogs underwent clinical, MR and CT examinations. Eleven malignant and ten non-malignant masses were evaluated. Osteosarcoma was the most commonly found malignant oral mass and gingival hyperplasia was the most commonly found benign mass. The results showed that MRI provided more accurate information regarding the size of the masses and invasion of adjacent structures although MRI and CT show similar accuracy in assessment of bone invasion. Calcification and cortical bone erosion was better seen on CT images. Whereas contrast-MRI provided useful additional information, contrast-CT had no added benefit. In general, oral masses located in the caudal mandible, oropharynx and maxilla are better evaluated using MRI, once the histological type has been verified.

Computed tomography (CT) and magnetic resonance imaging (MRI) are enabling more precise diagnosis and treatment planning in patients with diseases of the larynx. The aim of this article is to describe the role of these methods in assessment of the laringeal diseases and key local anatomic characteristics important for spread of the disease. CT and MRI have a valuable contribution to the staging of the tumors due to the possibility to show the relationship to the ventricular complex, involvement of the subumucosal spaces, defining craniocaudal and anterposterior extension, laringeal cartilage invasion, as well as regional lymph node metastases.

Abstract Context.—Death from corpora aliena in the larynx is a well-known entity in forensic pathology. The correct diagnosis of this cause of death is difficult without an autopsy, and misdiagnoses by external examination alone are common. Objective.—To determine the postmortem usefulness of modern imaging techniques in the diagnosis of foreign bodies in the larynx, multislice computed tomography, magnetic resonance imaging, and postmortem full-body computed tomography–angiography were performed. Design.—Three decedents with a suspected foreign body in the larynx underwent the 3 different imaging techniques before medicolegal autopsy. Results.—Multislice computed tomography has a high diagnostic value in the noninvasive localization of a foreign body and abnormalities in the larynx. The differentiation between neoplasm or soft foreign bodies (eg, food) is possible, but difficult, by unenhanced multislice computed tomography. By magnetic resonance imaging, the discrimination of the soft tissue structures and soft foreign bodies is much easier. In addition to the postmortem multislice computed tomography, the combination with postmortem angiography will increase the diagnostic value. Conclusions.—Postmortem, cross-sectional imaging methods are highly valuable procedures for the noninvasive detection of corpora aliena in the larynx.
