There is a prevailing concept that polypoid lesions of the colon are potentially malignant. Most radiologists rely on the double-contrast enema for the detection of colonic polyps. The new, simple, and most accurate method devised combines the use of large-field spotcompression radiography with high kilovoltage. The problem arising from this approach is no longer one of detection but rather the management of these lesions. A more conservative attitude toward very small, readily observable polyps seems justified.
