To evaluate the diagnostic impact and clinical significance of FDG-avid bone lesions detected by FDG-PET/CT in patients with lymphoma. The study population comprised 50 consecutive patients (mean age 41.7±15.5 years; 27 female, 23 male; 41 staging, 9 restaging) with Hodgkin’s disease (n=22) or aggressive non-Hodgkin’s lymphoma (n=28) in whom FDG-avid bone(More)
BACKGROUND Cystic lymph node metastasis (CLNM) is commonly found in human papillomavirus (HPV)-associated tonsillar squamous cell carcinoma (SCC). The aim of this study was to compare the accuracy in detecting cystic lymph node metastasis from tonsillar SCC between contrast-enhanced CT, ¹⁸F- fluorodeoxyglucose-positron emission tomography (FDG-PET),(More)
PURPOSE To examine whether magnetic resonance (MR) imaging findings of the cervical spine can predict pain relief after selective computed tomography (CT)-guided nerve root block and thus assist in the appropriate selection of patients who are suitable for this procedure. MATERIALS AND METHODS Sixty consecutive patients with cervical radicular pain were(More)
PURPOSE To prospectively evaluate the accuracy of ultrasonography (US) in depicting fatty atrophy of the supraspinatus (SSP) and infraspinatus (ISP) muscles, with magnetic resonance (MR) imaging as the reference standard. MATERIALS AND METHODS Institutional review board approval and informed consent were obtained. SSP and ISP muscles of 65 consecutive(More)
BACKGROUND This study assesses the additional value of (18)F-fluoro-2-deoxy-D-glucose positron emission tomography/CT ((18)F-FDG-PET/CT) with respect to synchronous primaries in patients undergoing panendoscopy for staging of head and neck squamous cell carcinoma. METHODS In all, 311 patients underwent both modalities. Cytology, histology, and/or(More)
We describe a localized proton magnetic resonance spectroscopy ((1)H-MRS) method for in vivo measurement of lipid composition in very small voxels (1.5 mm x 1.5 mm x 1.5 mm) in adipose tissue in mice. The method uses localized point-resolved spectroscopy to collect (1)H spectra from voxels in intra-abdominal white adipose tissue (WAT) and brown adipose(More)
The aim of the study was to evaluate 18F-FDG-PET/CT for the detection of synchronous primaries at initial staging of patients with head and neck squamous cell carcinoma (HNSCC). FDG-PET/CT images acquired between March 2001 and October 2007 in 589 consecutive patients (147 women, 442 men; mean age 61.5 years, age range 32–97 years) with proven HNSCC were(More)
Today, SPECT/CT is increasingly used and available in the majority of larger nuclear medicine departments. Several applications of SPECT/CT as a supplement to or replacement for traditional conventional bone scintigraphy have been established in recent years. SPECT/CT of the upper and lower extremities is valuable in many conditions with abnormal bone(More)
PURPOSE To explore the feasibility of tracking thulium (Tm)-1,4,7,10-tetraazacyclododecane-α,α',α'',α'''-tetramethyl-1,4,7,10-tetraacetic acid (DOTMA)-labeled cells in vivo by means of highly shifted proton magnetic resonance (MR) imaging as a potential alternative to established cell-tracking methods. MATERIALS AND METHODS All animal experiments were(More)
The case of a 17-month-old boy with symmetric involvement of both femora in chronic recurrent multifocal osteomyelitis (CRMO) is presented. Imaging showed an extraordinary involvement of both femoral diaphyses and distal metaphyses with extensive lamellar-like periosteal reactions. Diagnosis was based upon laboratory tests, bone scintigraphy, and MRI(More)
