In-vivo measurement of the elastic properties of soft tissue have been made using a variety of direct techniques, such as indentation probes and rotary shear actuators, but they are unable to access much of the soft tissue of interest. Indirect ultrasonic methods for imaging elastic properties of soft tissue were first introduced about 15 years ago, see Ophir (1991). Although the results of ultrasonic elastography studies have been quite promising, they may not be suited for applications requiring accurate quantification of soft tissue properties. An alternative to ultrasound, magnetic resonance imaging, has the advantage of enabling precise measurement of all three components of tissue displacement. The reconstruction of elastic properties from the imaged displacement field is called magnetic resonance elastography (MRE), and is the subject of this paper.

Summary. Diseases and injuries of the ankle joint and foot make up 6-12% of the total number of injuries and diseases of the musculoskeletal system. The article is devoted to the main diagnostic possibilities of magnetic resonance imaging (MRI), determination of indications for examination and protocols for the study of the ankle joint and foot. Based on the analysis of literature data, the high diagnostic efficiency of MRI in the identified pathologies of bone and soft tissue structures of this segment of the lower extremity was determined.

Results Of Treatment

Introduction: The treatment of patients with malignant fibrous histiocytoma as well as other soft tissue sarcomas is not sufficiently effective up to date, and has largely changed and reflects the alterations, occurred in oncology as a whole. The number of amputation decreased over the last 10-15 years. Some researchers associate the improvement of treatment outcomes with the development of combined and complex methods. The aim of the study is an improvement of the results of treatment of patients with soft tissue malignant histiocytoma on the basis of determination of factors, influencing local recurrence development. Materials and methods: The basis of our study was a comprehensive analysis of examination and treatment results of 130 patients with MFH of the soft tissue of limbs, of them in 84 patients (64.6%) the recurrences developed. The group included 45 (53.6%) males and 39 (46.4%) females. The major part of patients – 82.1% (60 patients) were older than 40 years. Results and conclusions: The number of recurrences after the treatment in general surgical facilities is 86.9%, whereas in the patients after the treatment in the specialized oncological facilities this figure is twice lower (40%). The characteristic of the medical facility where the patient receives his/her primary treatment largely affects the development of local recurrences, patients’ quality of life and overall survival rates. The surgical method remains the leading modality in the treatment of MFH of ST. Wide and radical excision of tumors in the specialized oncological facilities allows achieving better survival outcomes of the patients.

Magnetic resonance imaging has become the gold standard for soft tissue lesions evaluation especially after a traumatic event where there is need for diagnostic confirmation. The objective of the current paper was to evaluate the ability of magnetic resonance imaging in diagnosing soft tissue lesions in patients who underwent anterior cruciate ligament reconstruction compared with arthroscopic findings. Through the ability to diagnose soft tissue injuries, particularly meniscal lesions, magnetic resonance imaging should be considered as fundamental in guiding therapeutic management in patients with anterior cruciate ligament lesions.

: Differentiation of malignant from benign soft tissue tumors is challenging with imaging alone, including that by magnetic resonance imaging and computed tomography. However, the accuracy of this differentiation has increased owing to the development of novel imaging technology. Detailed patient history and physical examination remain essential for differentiation between benign and malignant soft tissue tumors. Moreover, measurement only of tumor size based on Response Evaluation Criteria In Solid Tumors criteria is insufficient for the evaluation of response to chemotherapy or radiotherapy. Change in metabolic activity measured by 18F-fluorodeoxyglucose positron emission tomography or dynamic contrast enhanced-derived quantitative endpoints can more accurately evaluate treatment response compared to change in tumor size. Magnetic resonance imaging can accurately evaluate essential factors in surgical planning such as vascular or bone invasion and “tail sign”. Thus, imaging plays a critical role in the diagnosis and treatment of soft tissue tumors.

Abstract. For more than a decade, Magnetic Resonance Imaging (MRI) has been routinely employed in clinical diagnostics because it allows non-invasive studies of anatomical structures and physiological processes in vivo and to differentiate between healthy and pathological states, particularly of soft tissue. Here, we demonstrate that MRI can likewise be applied to fossilized biological samples and help in elucidating paleopathological and paleoecological questions: Five anomalous guards of Jurassic and Cretaceous belemnites are presented along with putative paleopathological diagnoses directly derived from 3D MR images with microscopic resolution. Syn vivo deformities of both the mineralized internal rostrum and the surrounding former soft tissue can be traced back in part to traumatic events of predator-prey-interactions, and partly to parasitism. Besides, evidence is presented that the frequently observed anomalous apical collar might be indicative of an inflammatory disease. These findings highlight the potential of Magnetic Resonance techniques for further paleontological applications.
