'What' and 'where' visual streams define ventrolateral object and dorsolateral spatial processing domains in the prefrontal cortex of nonhuman primates. We looked for similar streams for auditory-prefrontal connections in rhesus macaques by combining microelectrode recording with anatomical tract-tracing. Injection of multiple tracers into physiologically(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 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)
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)
OBJECTIVES 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. METHODS 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.(More)
OBJECTIVE The purposes of this review are to summarize the indications for MDCT arthrography of the shoulder, highlight the features of MDCT acquisition, and describe the normal and abnormal MDCT arthrographic appearances of the shoulder. CONCLUSION MDCT arthrography is a valid alternative for shoulder imaging of patients with contraindications to MRI or(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)
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)
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)
