Radiologic Technology And Scientific Research Evaluation of Sinuses Diseases By Using Computed Tomography In Khartoum State Hospitals

Abstract

In this study the researcher assessed the effectiveness of computed tomography in the diagnosis of paranasal sinuses diseases and compared between two images planes (axial and coronal) when they are applied for the same cases. It was conducted at radiology departments in Asia specialized hospital, Yastebsheroon Omdurman center and modern medical center _ Khartoum. This study was expanded from July 2011 up to September 2011. Random samples of 50 patients, 26 males and 24 females their ages range from 10 to 70 years old with different symptoms were chosen, axial and direct coronal cuts are done to explain the suitable technique that demonstrate all the paranasal sinuses diseases clearly. The most affected by sinuses diseases ages from 21-40 years old , most patients were affected in the both sides, with history of sinuses diseases in their families, Maxillary sinuses are the most affected area, and Most patients suffer from headache. Axial images have a role in the diagnosis of paranasal sinuses problems but direct coronal scan is better and more sensitive than axial. These results are established by account the number of appearances that showing in coronal view and compared them with those appeared in axial section, where in acute, chronic and fungal sinusitis the sensitivity of coronal view was (77%, 61% and 61%) respectively compare to axial which was (22%, 36% and 38%) respectively. In the nasal polyp and granulomatous diseases the efficiency of coronal view was (62% and 65%) respectively, while in axial was (37% and 34%) respectively. In benign and malignant tumor the efficiency of coronal was 57% and 32% respectively, while in axial view was (42% and 21%) respectively. It can be said that the two image planes are perform together and used as essential technique of PNS, which help to obtain accurate diagnosis and demonstrate any Pathological changes that can affect paranasal sinuses.
