Thick reconstruction slices (greater than 3 mm) are NOT suitable for which of the following? Multiple correct answers are available. A. Multiplanar reformations B. Angiographic imaging C. Abdominal imaging D. Thoracic imaging {Ans: A and B}A patient in the emergency department is suspected of having a blowout fracture of right maxillary sinus. Structural damage to the eye will be best demonstrated with which of these filters? A. Edge-enhancing algorithms B. Bone algorithms C. Smoothing algorithms D. Sharpening algorithms {Ans: C. Smoothing algorithms All soft tissues, including the soft tissues of the eye, should be evaluated using images Reconstructed with a smoothing algorithm. This makes soft tissues look smooth and easier to see. The other algorithms listed create more edge enhancement, which is good for viewing bones but not good for viewing soft tissues.}Explain the difference between acquisition thickness and reconstruction slice thickness. {Ans: Acquisition thickness refers to the thickness of detector rows. Reconstruction thickness is the amount of scan data average into each slice of image data}During a routine CT scan of a pediatric chest, the radiologist requests that the technologist reconstruct the image data with 1.25 mm slices rather than 2.5 mm slices. One negative effect
