title: [The determination of left and right ventricular ejection and filling functions of the heart by fast cine MRT in the breath-hold technic in subjects].
abstract: OBJECTIVE
  Evaluation and comparison of localized and global left and right ventricular ejection and filling with fast cine MR imaging in the breath-hold technique.
  
  
  METHODS
  10 healthy volunteers were examined with a 1.5 Tesla unit and phased-array-coil using a segmented FLASH-2D sequence in breath-hold technique. Peak ejection and peak filling rates [PER, PFR end-diastolic volume (EDV)/s)]. time to PER and PFR [TPER, TPFR ms] and time of end-systole [TSYS in % RR-interval] of all slices (complete-slice-evaluation) were evaluated and compared to three left ventricular and one right ventricular slices (reduced three-slice-evaluation).
  
  
  RESULTS
  There were significant regional left ventricular differences of PER (p = 0.002) and PFR (p = 0.007), but not of TPER and TPFR. Ejection and filling indices of the left ventricular middle slice were closest to the overall evaluation of all sections. In the left-/right-side comparison the right ventricular PFR was higher than the left ventricular (5.1 and 4.2 EDV/s) and the right ventricular TPFR was earlier than the left (92.2 and 123.5 ms).
  
  
  CONCLUSIONS
  With fast cine techniques, regional and global left and right ventricular ejection and filling indices can be evaluated in addition to the global heart volume indices. The three-slice-evaluation represents a comprehensive, clear and time-saving method for daily routine.
