Small pneumothorax: what additional image to the routine pictures? : PA inspiration, PA expiration, Lateral (or lateral decub with affected lung UP) AEC not recommeneded - for expiration should be increased by 1/3 of that used for inspiration images Pneumothorax picture in PA inspo: what additional image to the routine pictures? : PA Expiration.... or lateral decub with affected lung up (air rising to the highest point in the hemithorax is more clearly visible then on erect views) Shoulder AEC hard soft tissue differentiation - what factors to adjust? : WINDOW WIDTH (narrower) smaller ww to enhance the amount of blacks and whites showing up so you can see the small differences in similar HU What is the best position + SID for highest spatial resolution for C-spine obliques? RAO : PA (reduce dose) (LAO RAO), long SID (180cm) Trauma: AP Caldwell with IOML perpendicular, how much angulation? 2 : 8 cephalic (to compensate for the OML) What is seen on CT of an intracranial SOL? : Midline shift OR ventricle compression SOL = space occupying lesion Pregnant worker already with 1mSv irradiated, how much for the remainder of the pregnancy? (declared at 3 months?) : 4msv total 3msv for remainder of pregnancy Projection for orbits: : (AP 15 Axial, PA 15 Axial, PA 30 Axial, AP 30 Axial) Modified waters (modified parietoacanthial projection) best projection TMJ image - angulation? : Axiolateral projection (Schuller method): 25-30 caudad - center 1.3cm anterior and 5cm superior to upside EAM Axiolateral oblique projection (Modified law method): 15 degree caudal angle - center 1.5inch superior to upside EAM 3 AP axial projection (modified towne): angle 35-degrees caudad from OML OR 42- degrees from IOML - center 3inches superior to nasion. Mandible image - how much was it turned (body is well demonstrated?) : 30 toward IR (45 degree rotation demonstrates mentum, 10-15 degree rotation provides a general survey of the mandible, true lateral demonstrates the ramus) Pelvis ischial spine not superimposed over the pelvic rim - closer to acetabulum - which way is it rotated? : LPO or RPO
