Common Applications Of Autopsy Roentgenology

MEDICOLEGAL CASES The use of roentgenographs in medicolegal autopsies is further discussed in Chapter 2; they are used (1) primarily for

• Identification purposes;

• The diagnosis of traumatic bone lesions;

• The identification of bullets and other foreign bodies; and

• Identification of gas in body cavities, vessels, and other sites.

Comparison of postmortem dental roentgenograms with in vivo films is the most common method of identification, particularly in the presence of advanced decomposition. Fractures and other bone lesions generally can be identified with greater accuracy in roentgenograms than by dissection. In fact, bone lesions of the extremities often cannot be studied in any other way. Most important, bullets and other radiodense objects may be impossible to find by any method other than roentgenogra-phy (Fig. 12-1). It should be noted, however, that a prosector still may have the greatest difficulties to find a small metallic object such as a bullet, even if it is clearly visible in the roentgenogram. In such an instance, the tissue with the foreign object should be removed and subdivided. Roentgenograms of the smaller samples will allow location of the area where the object can be found. If the tissue with the foreign object cannot be removed, additional roentgenographs with placement of radio-dense markers is helpful. Finally, roentgenograms are most helpful to identify gas, for example, if one wants to determine whether a newborn was breathing and thus has air in the lungs and the gastrointestinal tract (1). For other examples, see below.

Blood Pressure Health

Your heart pumps blood throughout your body using a network of tubing called arteries and capillaries which return the blood back to your heart via your veins. Blood pressure is the force of the blood pushing against the walls of your arteries as your heart beats.Learn more...
