Abstract

Fat suppressed STIR (short TI inversion recovery) sequences were compared to plain an contrast enhanced T1-weighted SE-sequences of head and neck tumours. 19 patients underwent MR imaging on a 0.5 Tesla system(T5-II, Philips). STIR imaging parameters: TR/TE = 1000/20 ms, inversion pulse 100 ms. All films were read by four radiologists. The image quality was graded: score from 0 to 5, by means that grade 5 = optimalquality. Sensitivity was 89 % in STIR, 96% in SE-sequences. Tumour delineation was graded good in the enhanced T1-weighted and enhanced fatsuppression images. The unenhanced imaging was superior in STIR (STIR/T1 = 2.8/2.43). The tumour contrast was best in contrast enhanced andplain STIR sequences (STIR contrast = 3.41), and in the contrast enhanced T1-weighted SE (3.33). STIR almost equaled T1 post-contrast in respect of tumour conspicuity, but the sensitivity was lower. STIR can be a supplement to SE, but cannot substitute T1 postcontrast. The combined use is expected to have the highest assessment value.
