[Evidence of malignant lymph node changes in the neck using scintigraphy].
Lymph-scintigraphic and tumour scintigraphic examinations were carried out on 46 patients with predominantly malignant new growth in the E. N. T. area. The lymph scintigraphy was carried out with 198Au colloid the tumour scintigraphy with 67Ga citrate. Both procedures were used single as well as combined in dependence on the aim.--The lymph scintigraphy gives a statement about the function and the state of the cervical lymph systems under physiologic and pathologic conditions as well as after operation (neck dissection) and radiotherapy. It supports the diagnosis of localisation and gives information about the severeness of surgical treatment of the lymphatic (node) system.--The suitability of 67Ga citrate is confirmed for the positive tumour scintigraphy. It is shown that malignant lymphomas have a greater concentration of the radio nuclide than carcinomas and their metastases. A minimum size of 1.5 cm in diameter ist necessary for a reliable representation. The tumour scintigraphy is valuable within differential diagnosis of treatment of initially unclear histology and of diffusible diagnosis of malignant processes. It contributes to a secure stage division and thus permits a better therapy planning. It supports the control of therapy because of an early recognition of the remaining parts of tumours and recurrence of tumours.--Lymph scintigraphy and tumour scintigraphy are an enlargement of the diagnostic possibilities of tumours in the head and throat area, whereby its combined application is advantageous especially for the exact diagnosis of localisation.
