BACKGROUND AND PURPOSE SCD has been reported to involve the inner ear and result in LH and LO. Our purpose was to examine the prevalence of inner ear involvement and to assess the relationship between clinical and imaging findings in patients with SCD. MATERIALS AND METHODS Review of our institution's imaging data base for patients with SCD who underwent(More)
Purpose To assess the determinants of technical failure of magnetic resonance (MR) elastography of the liver in a large single-center study. Materials and Methods This retrospective study was approved by the institutional review board. Seven hundred eighty-one MR elastography examinations performed in 691 consecutive patients (mean age, 58 years; male(More)
Adenocarcinoma is the most common histologic subtype of lung cancer. Recent advances in oncology, molecular biology, pathology, imaging, and treatment have led to an increased understanding of this disease. In 2011, the International Association for the Study of Lung Cancer, the American Thoracic Society, and the European Respiratory Society published a new(More)
OBJECTIVE To investigate the clinicoradiological manifestations of craniofacial bone infarcts in patients with sickle cell disease (SCD). MATERIALS AND METHODS After institutional review board approval, we identified 85 SCD patients who underwent head and neck magnetic resonance imaging (MRI) during a period of 5 years (January 1, 2004-December 31, 2008)(More)
Quantitative magnetic resonance (MR) imaging allows visualization of age-related changes in the normal human brain from functional, biochemical, and morphologic perspectives. Findings at quantitative MR imaging support age-related microstructural changes in the brain: (a) volume expansion, increased myelination, and axonal growth, which establish neural(More)
BACKGROUND AND PURPOSE Assessment of bone marrow is most commonly performed qualitatively in the spine or other large long bones. The craniofacial bones are less ideal for bone marrow analysis because of the relatively small bone marrow volume. Because patients with SCD often undergo repeated brain imaging to evaluate for cerebral vaso-occlusive disease,(More)
We are currently on the cusp of exponential growth in the understanding of the molecular landscape of bladder cancer. Emerging data regarding the mutational burden and targetable genomic and protein alterations in bladder cancer have allowed us to tap into treatments directed toward specific molecular characteristics of bladder cancer. In parallel, these(More)
OBJECTIVES The purpose of this prospective study was to characterize the MR relaxometric features of the major salivary glands in patients with sickle cell disease (SCD). METHODS 15 patients with SCD (aged 19.8-43.6 years) and 12 controls were imaged with the mixed turbo-spin echo pulse sequence. The major salivary glands were manually segmented and T1,(More)
room with acute onset of right-sided scrotal pain. The pain awoke him from sleep approximately 2 hours prior to presentation and began in the right lower quadrant, then quickly localized to the scrotum. With the onset of pain he noted swelling of the right testicle. There was no fever, chills, nausea, or vomiting. Upon examination, the abdomen was benign.(More)
PURPOSE To identify and characterize sickle cell disease (SCD)-related changes in the composition of mandibular bone marrow using qMRI relaxometry histograms. MATERIALS AND METHODS Thirteen SCD patients and 17 controls underwent brain MR imaging with the mixed turbo spin-echo (TSE) pulse sequence at 1.5T. The mandible was manually segmented and divided(More)
