Talc is a mineral widely used in the ceramic, paper, plastics, rubber, paint, and cosmetic industries. Four distinct forms of pulmonary disease caused by talc have been defined. Three of them (talcosilicosis, talcoasbestosis, and pure talcosis) are associated with aspiration and differ in the composition of the inhaled substance. The fourth form, a result(More)
Pulmonary alveolar microlithiasis (PAM) is a rare genetic lung disease characterized by calcifications within the alveoli. Mutations in the SLC34A2 gene, which encodes a type IIb sodium-phosphate cotransporter, are responsible for this disease, leading to intra-alveolar accumulation of phosphate that favors the formation of microliths. The hallmark of this(More)
OBJECTIVE In order to assess the effect of gray matter volumes and cortical thickness on antidepressant treatment response in late-life depression, the authors examined the relationship between brain regions identified a priori and Montgomery-Åsberg Depression Rating Scale (MADRS) scores over the course of an antidepressant treatment trial. METHOD In a(More)
OBJECTIVE To describe an ultrasound guided technique of shoulder joint injection at the rotator interval space, using an endocavitary transducer and performed by a radiologist with no previous experience with arthrography. MATERIALS AND METHOD Accuracy of the intra-articular puncture and incidence of complications were evaluated in 180 consecutive(More)
Congenital chest malformations can range from small and asymptomatic entities to large space-occupying masses that require immediate surgical treatment. They may affect the foregut, pulmonary airway, and vasculature. Hybrid conditions are commonly seen, with interrelated chest malformations having various radiologic and pathologic features. An understanding(More)
Recent technologic advances in multidetector computed tomography have allowed the performance of simultaneous acquisition dual-energy computed tomography (DECT). The advantages of this new technique include simultaneous visualization of lower voltage tube images with improved iodine conspicuity and the performance of material specific imaging, which(More)
OBJECTIVE This study evaluates noncompressive sonography of appendicitis in children according to the potential positions of the appendix. SUBJECTS AND METHODS We evaluated 425 consecutive boys and girls clinically suspected of having appendicitis. Noncompressive sonography used a 5.0-MHz curved-array transducer to assess deep layers. We systematically(More)
Pulmonary alveolar microlithiasis (PAM) is an uncommon chronic disease characterized by calcifications within the alveoli and a paucity of symptoms in contrast to the imaging findings. We present a 59-year-old woman with a 4-year history of shortness of breath on exertion. Lung auscultation revealed random wheezes and fine and coarse crackles. Pulmonary(More)
The purpose of this study was to compare the high-resolution computed tomography (HRCT) findings of pulmonary invasive aspergillosis and candidiasis in immunocompromised patients. The study included 54 immunocompromised patients (32 men, 22 women; 10 to 68 years of age, median 40 years) with a diagnosis of Aspergillus (n=32) or Candida (n=22) pulmonary(More)
