[Possibilities of abdominal ultrasonic diagnosis in the clinical follow up of malignant lymphomas].

Authors performed follow-up abdominal ultrasound examinations in malignant lymphomas, with abdominal lymphoid masses, during chemotherapeutic treatment. It was measured the volume-change of the examined abdominal lymphoid masses. Authors elaborated a new method, basing upon pseudocolour-coding of the ultrasonic picture. With the use of this method it became possible to evaluate quantitatively the change of internal echo-structure of abdominal lymphoid masses during the treatment. The change in the time of the measured structural parameteres was represented graphically. In the opinion of authors, the change of structural parameteres shows a characteristic connection with the course of the disease. The clinically evident relaps can be proceded more weeks by an unfavourable trend in the change of ultrasonic structure parameters. According to the results of the authors, the abdominal ultrasound diagnostic, complemented with the method of pseudocolour-coding can successfully help the clinical follow-up of malignant lymphomas.
