imaging of paranasal sinuses, focusing on neoplastic lesions
dependency of clinicians and surgeons on imaging studies for primary evaluation of patients and also for follow up of them, significantly increased in recent years, parallel to advances in imaging methods and new imaging modalities. regarding to these tips, it is important that we can use new concepts in conducting imaging to fulfill new requirements of clinicians and then provide sufficient da...
متن کاملMucoceles of the paranasal sinuses: MR imaging with CT correlation.
The MR findings in six cases of paranasal sinus mucoceles are described. Two basic MR appearances were encountered: either moderate to marked signal hypointensity in the expanded sinuses on T1- and T2-weighted images (four patients) or moderate to marked signal hyperintensity on T1- and T2-weighted images (two patients). These patterns appear to represent inspissated or hydrated sinus contents,...
متن کاملImaging of the nasal cavity and paranasal sinuses.
The CT examination in the coronal plane is the optimal imaging modality to evaluate the nasal cavity and the paranasal sinuses, especially for evaluating chronic inflammatory disease. This modality affords optimal display of the osteomeatal channels and best defines the extent of mucoperiosteal disease. Updated parameters for scanning afford a significant reduction of radiation. MR imaging supe...
متن کاملImaging of the paranasal sinuses and in-office CT.
Since the introduction of functional endoscopic sinus surgery (FESS) in the United States in 1985, the information gained from imaging has proved imperative in understanding regional morphology and guidance of surgical procedures. More than 20 years later, the importance of imaging continues to be the anatomic detail afforded by this technology, the roadmap it provides in planning the surgery, ...
متن کاملDisorders of the Paranasal Sinuses
Inflammation of the equine paranasal sinuses is a relatively uncommon disease that may be caused by primary bacterial or mycotic infections (Mason 1975a), or can be secondary to dental disease (van der Velden & Verzijlenberg 1984, Scott 1987, Tremaine & Dixon 2001a), facial trauma, sinus cysts, progressive ethmoid hematoma or sinonasal neoplasia (Mansmann & Wheat 1973, Gibbs & Lane 1987, Tremai...
