Abstract
Introduction. Due to the non-specific clinical findings and the reduced sensitivity of conventional radiography, soft tissue tumors (STT) were virtually unknown to radiologists until ultrasonography and computerized tomography were introduced. Because of its superior soft tissue contrast, multiplanar imaging capability, Magnetic Resonance Imaging (MRI) is the favored modality for the evaluation of soft tissue tumors. Purpose. MRI detection, characterization, and illustration of soft tissue tumors developed in the musculoskeletal system Material and method. The retrospective study refers to a group of 77 patients with suggestive clinical symptomatology for a soft-expanding process developed in the musculoskeletal system. Patients were examined according to a protocol that included complete clinical examination, two incidents radiographic examination, MRI, histopathological examination. The group consisted of 44 men (57%) and 33 (43%) women, aged between 7 and 80. Results. We presented the spectrum of identified types of tumors based on the MRI semiology elements (homogeneity and intensity of the signal in the native and post-contrast standard sequences, intra or extra compartmental localization, tumor size and shape), segmental location, and incidence relative to the histological type. Conclusions. Through high contrast resolution and the ability to acquire and display multiplanar, MRI is currently investigating choice in the detection and characterization of soft tumor tumors. The multiplanar images (axial, frontal, sagittal and oblique) provide complete data on the actual tumor extension, the appearance of vessels, nerves, bone segments, and adjacent joints to tumor formations, allowing the proper staging and appropriate therapeutic behavior.
