Radiologic errors in patients with lung cancer.

Abstract

Some 20 percent to 50 percent of detectable malignant lesions are missed or misdiagnosed at the time of their first radiologic appearance. These errors can result in delayed diagnosis and treatment, which may affect a patient's survival. Use of moderately high (130 to 150) kilovolt peak films, awareness of portions of the lung where lesions are often missed (such as lung apices and paramediastinal and hilar areas), careful comparison of current roentgenograms with those taken previously and the use of an independent second observer can help to minimize the rate of radiologic diagnostic errors in patients with lung cancer.
