title: [MR mammography of fatty tissue necrosis].
abstract: OBJECTIVE
  To evaluate MR-imaging for the differentiation of fatty necrosis (FN) of the breast.
  
  
  METHODS
  In 1016 MR mammographies FN was found in 13 patients aged 44 to 69 years. In all studies we used a proton-weighted fat suppressed sequence (STIR) and serial T1-weighted gradient echo sequences before and after bolus injection of Gd-DTPA, MRI was correlated to ultrasound and in 8 cases to mammographic findings.
  
  
  RESULTS
  All 15 FN displayed fat-isointense signal on T1-weighted and on proton-weighted, fat-suppressed sequences. They were delineated by a more or less wide rim of low signal intensity with sharp border to the center. After intravenous injection of gadopentetate dimeglumine they showed no increase of signal intensity in the centre and no increase, or only a minor increase, of the rim. Ultrasound could not distinguish FN from recurrent tumour in 6 cases. 7 FN looked like atypical cysts.
  
  
  CONCLUSIONS
  MR-mammography is very promising in the diagnosis of FN.
