Application Of Other Imaging Techniques

Except for ultrasonography which probably could be used in many autopsy settings without too much difficulty, other imaging techniques have also been widely used in recent years.

MAGNETIC RESONANCE IMAGING (MRI) This has been used particularly as a supplement to perinatal autopsies (20), autopsies in stillbirth (21), and pediatric autopsies in cases of suspected child abuse (22). MRI was useful in directing the autopsy and, particularly, the brain cutting to focal areas of abnormality (22). In a limited number of comparisons which included two adults, MRI was equal to autopsy in detecting gross cranial, pulmonary, abdominal, and vascular pathology, and superior in detecting air and fluid in potential body spaces (21).

COMPUTERIZED TOMOGRAPHY (CT) CT images produced in vivo are widely used in autopsy studies, primarily in brain cutting (see Chapter 6). The method also has been used to compare diagnostic yields of CT and MRI (see above) (23) and other research endeavors but we are not aware of routine use in autopsy settings.

ULTRASONOGRAPHY Use of this method in fetuses often failed to detect anomalies that were identified during autopsy (24).
