This volume is based upon presentations made to the 4th European Symposium on Radiopharmacology which was held under the auspices of the European Joint Committee on Radiopharma ceuticals (ENMS / SNME) in Athens from March 28 - 31, 1984. The Medical Insurance Foundation of the National Bank of Greece (TYPET) sponsored this meeting and the Joint Committee would like to express their gratitude to the local organising committee: G. Limouris, M. Pierroutsakou, A. Sarris, A. Tzoulis and C. Binas. A word of thanks also to Mrs. Tineke Busker who prepared the camera ready copy. The meeting reflects the continuing and growing interest in biodistribution and factors which can influence bio distribution in the clinical situation. The choice of sub jects, respiration, cerebral function, biodistribution and metabolism complement earlier volumes in this series and reflect European interests in these areas. P. H.
