OBJECTIVE The purpose of this study was to test the hypothesis that freehand real-time MRI-guided lumbar spinal injection procedures are feasible, accurate, and safe when performed with a clinical open-bore 1.5-T MRI system. MATERIALS AND METHODS A retrospective analysis was made of spinal injection procedures performed over an 18-month period. Forty-nine(More)
PURPOSE To describe whole-body magnetic resonance (MR) imaging appearance of chronic recurrent multifocal osteomyelitis (CRMO) and assess the role of MR imaging versus radiography in diagnosis of disease and correlation with clinical findings and laboratory data. MATERIALS AND METHODS Institutional review board approved this retrospective HIPAA-compliant(More)
OBJECTIVE The objective of our study was to prospectively test the hypothesis that combined diagnostic and interventional MRI of the sacroiliac joints can be performed efficiently and effectively. SUBJECTS AND METHODS Over a 12-month period, 60 patients (32 women and 28 men; median age, 28 years; age range, 18-49 years) with chronic lower back pain(More)
We prospectively evaluated the feasibility and technical properties of a dedicated interventional magnetic resonance (MR) imaging protocol for near-real-time MR fluoroscopy-guided bilateral lumbar facet joint injections. A total of 44 facet joint injections were performed in 22 patients using a C-shaped open 0.2-T MR imaging system (Magnetom Concerto,(More)
OBJECTIVE The aim of our study was to test the feasibility and specific properties of MR imaging-guided adrenal biopsy using an open 0.2-T scanner and MR fluoroscopic fast imaging with steady-state free precession sequences. CONCLUSION MR imaging-guided biopsy of the adrenal gland is feasible and safe. In all patients, appropriate specimens were obtained(More)
Image-guided radiofrequency (RF) ablation is a minimally invasive therapy option in the treatment of primary and secondary hepatic malignancies. Magnetic resonance (MR) imaging offers an accurate pre-interventional imaging having important impact on patient selection and planning of the ablation procedure. Peri-interventional imaging is used for targeting,(More)
Periprosthetic joint infections are a devastating complication after arthroplasty and are associated with substantial patient morbidity. More than 25% of revisions are attributed to these infections, which are expected to increase. The increased prevalence of obesity, diabetes, and other comorbidities are some of the reasons for this increase. Recognition(More)
OBJECTIVE The objective of this study was to evaluate the diagnostic performance and safety of magnetic resonance (MR) imaging-guided percutaneous mediastinal biopsy procedures using a 0.23-T open MR system with optical tracking navigation. MATERIALS AND METHODS A retrospective analysis of 59 participants (38 males and 21 females; mean age, 45 years;(More)
To evaluate the efficacy and safety of MRI-guided percutaneous biopsy procedures of head and neck lesions using 0.23T open MRI with optical tracking. A retrospective analysis of 77 patients (51 male, 26 female; mean age, 43 years; range, 11–88 years) who underwent MRI-guided percutaneous biopsy of a head and neck lesion was performed. Mean lesion diameter(More)
OBJECTIVE Chloroma, also know as granulocytic sarcoma, is a localized extramedullary tumor composed of malignant cells of the myeloid cell line. It occurs most frequently secondary to a history of myelogenous leukemia as extramedullary relapse. New treatment regimens, including allogeneic stem cell transplantation, extensive use of donor lymphocyte(More)
