Springer MRI/CT and Pathology in Head and Neck Tumors A Correlative Study by Mark W. Ragozzino, Michael P. Joseph, Other Alfred L. Weber, R. Chisin
tic knowledge, a multidisciplinary approach is indis Over the past 60 years, radiology has progressively uncovered the human body. At first a fleshless skele pensable: clinicians, radiologists, surgeons, radio therapists, and pathologists must all contribute their ton for global study, the body then appeared in slices, until with present techniques its smallest respective inputs for every patient referred. More over, experience is acquired through knowledge of structures are revealed. The physician at the com cases whose diagnosis is certain, and with which new puter console is constantly amazed at the never ending series of organ sections and their mUltiple cases can be compared. In this way a data base is created, whether in the physician'S memory or in images arising through manipulation of the signal. Cerebral convolutions, orbital content, bone mar that of the computer, which is helpful in making row, the face and all its bones can now be made visi diagnoses. ble without any danger to the patient.
