Because they result from the perspective from which a particular view is taken, these supposed lesions disappear when the breast is viewed from another angle. There are several previously described situations in which a projectile is not immediately localized by radiography. Outcomes of one-view-only findings that prompted recall for additional imaging were reported as follows. The site is secure. Can the question clinical question still be answered? Misregistration artifacts, which appear as blurring, streaking, or shading, are caused by patient movement during a CT scan. Destabilization and intracranial fragmentation of a full metal jacket bullet. There are scattered areas of fibroglandular density. If a persistent abnormality is seen, we will commonly ask for an ultrasound to exclude an underlying lesion in the breast. a patella protection, tighter digital collimation in conjunction with reprocessing will correctly assign the correct values of interest, loss of contrast in areas of different pixel density yet not change in density can be seen i.e. An image need only be repeated if artifact prevents the clinical question from being answered confidently.
