“…In this study, we have used DECT images and VNCa applications to identify BME around the ankle in a cohort of non-traumatic patients, with our results confirming a role for DECT as a useful application [24,33]. Guggenberger et al studied 30 traumatic ankle injuries using DECT, obtaining 90% sensitivity for both readers and 80.5% and 81.6% specificity, for R1 and R2, respectively.…”

“…DECT has also recently been used for the diagnosis of non-traumatic BME around the hip joint [31,32]. Furthermore, virtual non-calcium (VNCa) applications have been used for diagnosing BME of the ankle in a mixed cohort of traumatic and non-traumatic patients [33]. The sensitivity and specificity achieved were 92.0% and 86.6%, for reader 1 (R1) and 88.0% and 86.6%, for reader 2 (R2), respectively, with very good inter-observer agreement (k = 0.87) [33].…”

Nevertheless, the capabilities of DECT in identifying BME around the ankle in a cohort of non-traumatic patients is yet to be reported.…”

The purpose of this study is to assess the impact of MRI findings on management of symptomatic patients following RFA of OO. Retrospective review of 43 patients with RFA for OO between June 2010 and June 2017 was performed. Patient, nidus, and ablation data were reviewed. Pre- and 6–8 weeks post-procedural MRI (n = 32) were compared for coverage of nidus by ablation zone, bone marrow edema, nidus hyperintensity, and other findings. Baseline pain levels and analgesic use were compared with post-procedural follow-up visit at 6–8 weeks. Three groups of clinical and MRI outcomes of complete (CR), partial (PR), and no response (NR) were defined. A weighted kappa statistic was used to assess for agreement. Clinical responses were CR in 34/43 (79.1%, 95% CI: 64.0–90.0%), PR in 8/43 (18.6%), and NR in 1/43 (2.3%) patients. All 19/32 patients with MRI CR experienced clinical CR. One patient with MRI NR had clinical NR. All 7/32 patients with clinical PR had MRI PR. All 4/43 complications were in MRI PR or NR groups. Substantial agreement was observed between MRI and clinical outcomes (kappa: 0.69, 95% CI: 0.45–0.95). MRI helped determine etiologies in all symptomatic patients and their management (n = 8). MRI is recommended for symptomatic patients after ablation.

“…In addition, the disease types included in the present study were limited, and the inclusion of a larger cohort is needed. Foti et al [21] reported that dual-energy CT represents an accurate imaging tool for bone marrow edema of the ankle compared with MRI. We did not perform a comparative study of MRI and dual-energy CT.…”

Objective To explore the incidence and significance of intra- and extra-osseous edema associated with benign tumors and tumor-like diseases. Methods Magnetic resonance imaging (MRI) data from 300 benign osseous tumors and tumor-like diseases diagnosed by pathology were retrospectively reviewed. Borderline tumors, cases associated with pathological fractures, and skull lesions were excluded from the study. Bone marrow and soft tissue edema were defined on T2WI with fat suppression on MRI in all cases. The incidence rate of edema in benign tumors and tumor-like diseases was determined using the χ2 test. The preoperative diagnoses were reviewed, and the effect of edema on the differential diagnosis of benign and malignant tumors was analyzed. Results The incidence rate of bone marrow and soft tissue edema associated with benign tumors and tumor-like diseases was 35.7% (107/300), including 84.4% (27/32) Langerhans cell histiocytosis, 86.4% (19/22) osteoblastoma, 93.9% (31/33) osteoid osteoma, and 85.2% (23/27) chondroblastoma cases. There was no statistically significant difference in the incidence of edema among the four diseases (χ2 = 1.7, P > 0.05). Of 107 cases associated with edema, 49 (45.8%) were misdiagnosed as malignant tumors by MRI preoperatively. Conclusion Bone marrow and soft tissue edema are a common finding associated with benign bone tumors and tumor-like diseases, and they are frequently detected in Langerhans cell histiocytosis, osteoblastoma, osteoid osteoma, and chondroblastoma.
