Conventional Radiography
Uses of Conventional Radiography
Radiography is the most readily available imaging method. Typically, it is the first imaging method indicated to evaluate the extremities, chest, and sometimes the spine and abdomen. These areas contain important structures with densities that differ from those of adjacent tissues. For example, radiography is a first-line test for detecting the following: Fractures:White bone is well seen because it is adjacent to gray soft tissues. Pneumonia:Inflammatory exudate that fills the lungs is well seen because it contrasts with adjacent, more radiolucent air spaces. Intestinal obstruction:Dilated, air-filled loops of intestine are well seen amidst the surrounding soft tissue.
