S. Steiner et al., MRI OF FOCAL LIVER-LESIONS USING A 1.5 T TURBO-SPINECHO TECHNIQUE COMPARED WITH SPINECHO TECHNIQUE, RoFo. Fortschritte auf dem Gebiete der Rontgenstrahlen und der neuenbildgebenden Verfahren, 163(2), 1995, pp. 141-147
Aim The aim of our study was to evaluate a T-2-weighted turbo-spinecho
sequence in comparison to a T-2-weighted spinecho sequence in imaging
focal liver lesions. Methods:In our study 35 patients with suspected
focal liver lesions were examined. Standardised imaging protocol inclu
ded a conventional T-2-weighted SE sequence (T-R/T-E = 2000/90/45, acq
uisition time = 10.20) as well as T-2-weighted TSE sequence (T-R/T-E =
4700/90, acquisition time = 6.33). Calculation of S/N and C/N ratio a
s a basis of quantitative evaluation was done using standard methods.
A diagnostic score was implemented to enable qualitative assessment. R
esults: In 7% (n = 2) the TSE sequence enabled detection, further live
r lesions showing a size of less than 1 cm in diameter. Comparing anat
omical details the TSE sequence was superior. S/N and C/N ratio of ana
tomic and pathologic structures of the TSE Sequence were higher compar
ed to results of the SE sequence. Conclusion: Our results indicate tha
t the T-2-weighted turbo-spinecho sequence is well appropriate for ima
ging focal liver lesions and leads to reduction of imaging time.
