title: [Dynamic sequences of MR in evaluation of anatomy and function of pelvic floor by perimenopausal women].
abstract: Pelvic organ prolapse is one of the most common disorders and it concerns over 50% of women over the age of fifty who gave birth.
  
  
  BACKGROUND
  The purpose of this study was to establish a clinically useful protocol of MR investigation in the assessment of pelvic organs position changes during rest and in time of Velsalva test
  
  
  OBJECTIVE
  The material includes 17 postmenopausal women (48- 59-years-old) who were examined due of lumbosacralis discopathy in MR division of USK 1 in Lodz since 2007. The examination was extended to pelvic organs imaging with the help of Velsalva test.
  
  
  RESULTS
  Having compared static and dynamic images of investigated group and results of reference lines measurements, we have found normal pelvic organ position comparing to the H line in case of 10 women, in case of 5 women there was just a small displacement--up to 2 cm under the H line--and in case of 2 other women 2 cm above the H line. We have also found substantial increase of P line length (over 25% during tenesmus) in women with pelvic floor disorders.
  
  
  CONCLUSIONS
  Dynamic MR imaging proves extremely useful in evaluation of pelvic organs position changes during rest and in time of Velsalva test.
