MRI DIAGNOSIS OF RECURRENCE OF GYNECOLOGI CAL TUMORS

Because of the differences in the signals from recurrent tumours and f ibrosis during MRT, this method is highly suitable for differentiating between recurrent gynaecological tumours and scar formation. The valu e of MRT in investigating suspected recurrences was studied in 27 pati ents aged between 34 and 83 years. It was possible to distinguish betw een recurrent tumour with its high intensity signal from low signal fi brosis, using T-2-weighted spin echo sequences in all cases. By means of multiplanar reconstruction and because of its high soft tissue cont rast it was possible to determine the extent of tumour growth and diff erentiate it from surrounding tissues. With a sensitivity of 90%, spec ificity of 100% and accuracy of 92%, MRT is superior to all other imag ing methods, including CT, in the diagnosis of tumour recurrence.
