title: [In vivo 31 phosphorus spectroscopy of tumors: pre-, intra- and post-therapy].
abstract: Using 31P-MR spectroscopy spectra with good signal-to-noise ratio were obtained in five different types of tumours (Ewing's sarcoma, osteosarcoma, malignant melanoma, metastases from a squamous cell carcinoma, parotid adenoma). Surface coils were used. Short- and long-term follow-up after chemotherapy was possible in some cases. In the short-term follow-up, changes in the phosphocreatine and inorganic phosphate resonances could be observed within minutes after the start of the infusion. In the longer follow-ups, changes in phosphodiester and phosphomonoester resonances were observed within two days. There were no significant changes in tissue pH during treatment, but increased pH values were observed in all tumours.
