TO STUDY DISEASE AND ITS EXTENT 3. TO PLAN FOR SURGERY 4. POST .OPERATIVE.VARIOUS CUTS: VARIOUS CUTS 1. CORONAL 2. AXIAL 3. SAGITTALCORONAL CUTS: CORONAL CUTS POSITION PRONE, CHIN HYPER-EXTENDED. SCANNER GANTRY IS ANGLED PERPENDICULAR TO HARD PALATE. FROM ANTERIOR WALL OF FRONTAL SINUS THROUGH POSTERIOR WALL OF SPHENOID SINUS.CORONAL : CORONAL ADVANTAGES 1.SURGEON S VIEW 2. OSTEOMEATAL UNIT BETTER VISUALISED 3.RELATIONSHIP OF BRAIN TO THE ETHMOID ROOF PITTFALLS 1.ANTERIOR AND POSTERIOR WALLS OF THE FRONTAL, MAXILLARY AND SPHENOID SINUSES --------NOT WELL SEEN 2.

MRI is extremely helpful in complicated sinonasal disease 2. MRI can discern secretions and mucosa from masses 3. Also look for foraminal extension, whether by perineural spread or direct invasion of the tumor 2. Infiltration of the dura and the cerebrum can be depictedSINUSITIS: SINUSITISFUNGAL SINUSITIS: FUNGAL SINUSITISCARCINOMA: CARCINOMAUSG OF PARANASAL SINUSES: USG OF PARANASAL SINUSES has been proposed as a diagnostic procedure intended to determine the presence of sinus fluid in clinical cases of sinusitis also proposed for use in demonstrating mucosal wall thickening, focal soft tissue masses, and complex collections in the paranasal SinusesNormal maxillary sinus: Normal maxillary sinusFluid filled maxillary sinus: Fluid filled maxillary sinusPet ct scan: Pet ct scan clinical PET imaging relies on [18F] fluorodeoxy -glucose (FDG) uptake.
