title: [Value of magnetic resonance tomography prior to surgery and irradiation of peripheral soft tissue tumors].
abstract: The experience with magnetic resonance imaging (MRI) of 37 patients with peripheral soft tissue tumours and tumour-like lesions is reported. MRI proved to be a highly sensitive method in detecting soft tissue tumours. The main advantages of MRI compared to CT were the high contrast resolution of MRI and the multiplanar display. The anatomic setting of the soft parts tumour could be defined in most cases as either intracompartmental or extracompartmental. The relationship to the major neurovascular bundles and bone could be assessed accurately. Tumour-induced subtle periosteal reactions and cortical erosions are better defined with CT and plain film, especially. An imaging technique using small excitation angles, echoes produced by gradient inversion and extremely fast repetition times ("Fast Field Echo Imaging") is capable of producing MR images in only a few seconds acquisition time. Preliminary experience shows that soft tissue tumours can be evaluated with this rapid pulse sequence.
