PURPOSE To determine the diagnostic accuracy of ultrasonographically (US) and stereotactically guided fine-needle aspiration biopsy (FNAB) in the diagnosis of nonpalpable breast lesions. MATERIALS AND METHODS At 18 institutions, 442 women who underwent 22-25-gauge imaging-guided FNAB were enrolled. Definitive surgical, core-needle biopsy, and/or follow-up(More)
PURPOSE To compare the abilities of magnetic resonance (MR) imaging and computed tomography (CT) in detection of lymph node metastasis from head and neck squamous cell carcinoma. MATERIALS AND METHODS MR imaging and CT were performed with standard protocols in patients with known carcinoma of the oral cavity, oropharynx, hypopharynx, or larynx.(More)
PURPOSE To determine the optimal imaging modality for diagnosis and staging of ovarian cancer. MATERIALS AND METHODS Two hundred eighty women suspected to have ovarian cancer were enrolled in a prospective study before surgery. Doppler ultrasonography (US), computed tomography (CT), and magnetic resonance (MR) imaging were used to evaluate the mass;(More)
BACKGROUND Image-guided core needle biopsies (CNBs) are commonly used as the initial sampling method for nonpalpable, mammographically detected breast lesions. Although prior studies have shown that this procedure is a highly sensitive and accurate method for the detection of breast cancer, the level of diagnostic agreement between pathologists in the(More)
OBJECTIVES To obtain information from decision makers about attitudes toward hospitalization and the factors that influence their decisions to hospitalize nursing home residents. DESIGN Cross-sectional survey. SETTING Four hundred forty-eight nursing homes, 76% of which were nonprofit, from 25 states. PARTICIPANTS Medical directors and directors of(More)
RATIONALE AND OBJECTIVES To determine the diagnostic accuracy of stereotactically and sonographically guided core biopsy (CB) for the diagnosis of nonpalpable breast lesions. MATERIALS AND METHODS Twenty-two institutions enrolled 2,403 women who underwent imaging-guided fine needle aspiration followed by imaging-guided large-CB of nonpalpable breast(More)
PURPOSE To compare the accuracies of computed tomography (CT), magnetic resonance (MR) imaging, and bone scintigraphy in staging disease in patients with neuroblastoma. MATERIALS AND METHODS Ninety-six children with newly diagnosed neuroblastoma were enrolled in a multicenter prospective cohort study. CT, MR, and bone scintigraphy were used to evaluate(More)
IMPORTANCE Nursing home residents with advanced dementia commonly experience burdensome and costly hospitalizations that may not extend survival or improve the quality of life. Fragmentation in health care has contributed to poor coordination of care for acutely ill nursing home residents. OBJECTIVE To compare patterns of care and quality outcomes for(More)
PURPOSE OF THE STUDY Culture change models are intended to improve the quality of life for nursing home residents, but the impact of these models on quality of care is unknown. We evaluated the impact of the implementation of nursing home culture change on the quality of care, as measured by staffing, health-related survey deficiencies, and Minimum Data Set(More)
OBJECTIVES To model the predictors of the time to first acute hospitalization for nursing home residents, and accounting for previous hospitalizations, model the predictors of time between subsequent hospitalizations. DATA SOURCES Merged file from New York State for the period 1998-2004 consisting of nursing home information from the minimum dataset and(More)
