[Ovarian tumors in the computer tomographic image--the correlation of histology and CT diagnosis]

The value of CT in respect of preoperative determination of tumour status and of tumour classification was studied using 127 histologically identified ovarial tumours as basis in a blind study via mutual image classification by the two participating institutes. The medium accuracy of diagnosis was 82%, but the results were found to be greatly dependent on tumour histology. Quotas of more than 90% were obtained in case of functional cysts, cystomas , cystadeno -carcinomas and dermoids, whereas classification was less successful with the other types of tumours such as germ cell tumours, tumours of the sexually differentiated stroma, metastases and tubo- ovarial abscesses.
