T1-weighted sequences before and after the application of contrast medium and T2-weighted sequences are used for magnetic resonance imaging of malignomas of the oral cavity and the oropharynx. The authors studied the utility of short tau inversion recovery fat suppression (STIR) in T2-weighted turbo spin echo sequences (TSE).
Twenty patients with malignomas of the oral cavity and oropharynx were examined on a 1.0 Tesla magnetom using T2-weighted TSE-sequences with and without STIR as well as T1-weighted spin echo sequences before and after the application of contrast medium.
STIR was successfull in all patients. STIR worsened the signal-noise-ratio significantly, but improved tumor delineation compared to T2-TSE without fat suppression in 75% according to three different investigators.
The STIR technique is beneficial for the progress in diagnostic imaging of cancer of the oral cavity and oropharynx.
应用造影剂前后的T1加权序列以及T2加权序列用于口腔和口咽恶性肿瘤的磁共振成像。作者研究了短反转时间反转恢复脂肪抑制（STIR）在T2加权快速自旋回波序列（TSE）中的效用。
对20例口腔和口咽恶性肿瘤患者使用1.0特斯拉磁共振成像仪进行检查，采用有和没有STIR的T2加权TSE序列以及应用造影剂前后的T1加权自旋回波序列。
所有患者的STIR均成功。STIR显著降低了信噪比，但据三位不同的研究者评估，与未进行脂肪抑制的T2-TSE相比，75%的病例中STIR改善了肿瘤边界的显示。
STIR技术有助于口腔和口咽癌诊断成像的进展。
