Holderlin to his mother, 16. November 1799 A. Introduction 1 General The modem cross-sectional imaging methods of sonography and computed to- mography, developed in the early 1970s, have contributed greatly to noninva- sive studies of the parenchymatous organs and permit the evaluation of patho- logic changes in areas that were previously accessible only to invasive, indirect, or inadequate examination.
