“…Peripheral nerve damage results in a loss of proprioception, instability, microtrauma, and posterior foot deformity. For evaluation of erosive or destructive changes, subchondral cysts, intra-articular bodies, and edema, chemical shift imaging and Dixon sequences are a powerful tool because they allow assessment of both cortical integrity and edema pattern (56).…”

Diagnosis and treatment of foot disease in patients with diabetes is a common clinical-radiologic challenge, particularly the differentiation of neuropathic arthropathy from osteomyelitis. Conventional clinical tests and imaging techniques have limited accuracy for evaluation of the diabetic foot. The introduction of morphologic magnetic resonance (MR) imaging in these patients has provided a qualitative leap in diagnosis. The characteristics of soft-tissue and bone marrow edema and their patterns of distribution throughout the foot allow discrimination between both entities. However, in certain scenarios, the application of MR imaging to this problem is limited because of overlapping features between the two and the coexistence of infection and neuropathic changes. Recent technical advances in MR imaging sequences have increased the capability to add functional quantitative information to structural information. Diffusion-weighted imaging is useful to determine the presence and extension of osteomyelitis. Dynamic contrast-enhanced MR imaging may help to detect differences between the vascularization patterns of neuropathic arthropathy and osteomyelitis. MR angiography (with or without contrast material) is used in clinical practice to identify candidate distal vessels for revascularization. MR neurography, and especially diffusion-tensor imaging, provides quantitative information about neural damage. These new sequences may help in assessment of the different pathophysiologic conditions that occur in the diabetic foot. The physical basis of these techniques, their limitations, and their potential applications for diabetic foot assessment are detailed in this article. The introduction of advanced MR imaging multiparametric protocols, with the aim of enhancing the overall diagnostic accuracy of MR imaging, may help in treatment decision making and lead to improved patient outcomes.

“…Normal yellow marrow will show no significant change in signal intensity after contrast injection compared to baseline. Involved bone in joints with septic arthritis will show a characteristic TIC (type II curve), with an intense early enhancement and later slight progressive increase of the enhancement slope compared to baseline marrow, without evidence of delayed washout[ 43 ]. Perfusion of epiphysis of involved bone has been shown to be lower than expected on the initial phases of DCE-MRI likely due to an increase in hydrostatic pressure or possibly septic thrombosis of epiphyseal vessels.…”

Magnetic resonance imaging (MRI) has allowed a comprehensive evaluation of articular disease, increasing the detection of early cartilage involvement, bone erosions, and edema in soft tissue and bone marrow compared to other imaging techniques. In the era of functional imaging, new advanced MRI sequences are being successfully applied for articular evaluation in cases of inflammatory, infectious, and degenerative arthropathies. Diffusion weighted imaging, new fat suppression techniques such as DIXON, dynamic contrast enhanced-MRI, and specific T2 mapping cartilage sequences allow a better understanding of the physiopathological processes that underlie these different arthropathies. They provide valuable quantitative information that aids in their differentiation and can be used as potential biomarkers of articular disease course and treatment response.

“…[1][2][3][4][5][6][7][8][9][10][11] Conversely, benign diseases are still under investigation and, so far, the treatment of only osteoid osteoma has appeared in literature. [12][13][14][15] There is scarce literature describing the characteristics and the treatment of benign lesions other than osteoid osteoma, 16 and the studies are usually restricted to a low number of patients. [17][18][19] Sometimes, the patients are grouped with others presenting more frequent pathologies of other nature.…”

The objective of this study was to evaluate the role of MR-guided focused ultrasound surgery and radiofrequency ablation in the management of bone and soft-tissue lesions. Musculoskeletal interventional radiology represents an interesting option for the treatment of benign bone and soft-tissue lesions to avoid the invasiveness of surgery and related risks. The imaging techniques now available, besides representing an optimal guide, allow control of the temperature reached in the region of interest, avoiding or minimizing damage to the sensitive structures surrounding the lesion. INTRODUCTIONInterventional radiology (IR) procedures are well established in the treatment of malignant, particularly metastatic, diseases of bone and soft tissues and are exhaustively described in literature.
