The authors categorized 125 spinal lesions in cancer patients and 127 lesions in patients with back pain according to their location in the vertebra on single photon emission computed tomographic (SPECT) images. Forty-four lesions were metastases, all in patients with known malignancy. Lesions in the apophyseal joints were all benign. Lesions manifesting as(More)
The value of magnetic resonance imaging (MRI) in establishing the diagnosis of sacroiliitis was studied in 20 patients with established or suspected disease on conventional radiographs and in 10 healthy subjects. Coronal T1 weighted, axial T2 weighted and proton density MRI images of the sacroiliac joints in addition to plain film radiographs were obtained.(More)
Although visualization of articular fluid on MR images of the knee is common, no specific MR criteria that enable assessment of the quantity of the effusion have been established. We performed MR of three cadaveric knee specimens after the instillation of increasingly large volumes of fluid and studied the distribution of the fluid. When 4 ml of fluid was(More)
The cauda equina syndrome is an uncommon and poorly understood complication of ankylosing spondylitis. The clinical and radiologic findings in five patients with this syndrome are described. Typical findings include cutaneous sensory impairment of the lower limbs and perineum with sphincter disturbances. Motor impairment occurs less frequently, and(More)
OBJECTIVE To evaluate the role of magnetic resonance imaging (MRI) and single photon emission computed tomography (SPECT) in the detection of sacroiliitis in patients with clinical features of inflammatory back disease but without conventional radiographic changes. METHODS Twenty-four patients with inflammatory low back pain (ILBP) and normal or(More)
OBJECTIVE The purpose of this study was to evaluate the utility of selective injection of local anesthetic into hindfoot articulations for localizing the source of posttraumatic pain and to compare clinical response with the severity of degenerative change in the various articulations evident on plain radiographs or CT scans. SUBJECTS AND METHODS(More)
PURPOSE The purpose of this study was to examine perceived barriers to clinic attendance and strategies to overcome these barriers for adolescents with sickle cell disease. MATERIALS AND METHODS This was a 2-phased study, which used focus groups (n=13) and individual semistructured interviews (n=32) with adolescent patients (aged 13 to 21 y) from 3(More)
OBJECTIVE The aims were to describe and compare generic family functioning in children with five different chronic conditions and healthy comparisons, and to examine the relations between family functioning and sociodemographic variables. METHODS A secondary data analysis from six independent studies including 301 children (cystic fibrosis: n = 59;(More)
OBJECTIVE To conduct a multidimensional assessment of pain in children with sickle cell disease (SCD). Variables included parent and child reports of pain location and intensity, qualitative descriptors of pain, perceptions regarding the seriousness and severity of SCD, and environmental and emotional factors associated with pain. METHODS We replicated(More)
