STUDY OF ORBITAL NEOPLASMS BY MAGNETIC RESONANCE IMAGING PROCEDURE.

The neoplasms of the organ of vision are characterized by significant polymorphism, which is due to the histological diversity of the structures in the eye socket. Almost all types of neoplasms described in humans are found in the orbit. The study aimed to determine the diagnostic value of magnetic resonance imaging in patients with tumors in the eyeball and the eye socket, as well as to determine the superiority of the MRI procedure compared to other instrumental methods of research.

Risk-based serological survey of bluetongue and the first evidence of bluetongue virus serotype 26 circulation in Tunisia.

Background: Bluetongue (BT), a vector-borne disease of wild and domestic ruminants, is responsible for severe economic losses in flocks. To reduce this impact, a surveillance and control plan was implemented in Tunisia. However, the epidemiological situation of BT remains incompletely understood, especially for the circulating serotypes.

[Computed tomography and magnetic resonance angiography of brain meningiomas].

The article analyzes magnetic resonance angiography and computed tomography angiography for diagnosis of blood vessels in the brain. 215 patients with brain meningiomas were examined in 2006-2013 years. Among them 206 adults: 90 (43,3%) men, 119 (56,7%) weman from 19 to 76 years (mean age - 51,4 yrs) and 6 children (4 boys, 2 girls) from 6 to 16 years (mean age - 12 yrs).

Differentiation between benign and malignant meningiomas using diffusion and perfusion MR imaging.

The purpose of the study was to investigate the utility of diffusion-weighted (DW) and perfusion-weighted (PW) MR imaging to differentiate benign and malignant meningiomas which were verified histologically. A total of 29 patients with meningiomas (22 benign and 7 malignant) underwent conventional, perfusion and diffusion MR imaging. Conventional MRI revealed the ordinary signs of tumor.
