There is a lack of standardized approach and terminology to classify the diverse spectrum of manifestations in tuberculosis. It is important to recognize the different clinical and radiographic patterns to guide treatment. As a result of changing epidemiology, there is considerable overlap in the radiologic presentations of primary tuberculosis and post-primary tuberculosis. In this article we promote a standardized approach in clinical and radiographic classification for children suspected of having or diagnosed with childhood tuberculosis...

This paper will examine deposition patterns of four radionuclides following the Fukushima-Daiichi accident. For nearly 13 d following the event, fission products were released into the environment through planned venting procedures and hydrogen explosions. To assist the government of Japan (GOJ) in the assessment of the releases, the National Nuclear Security Administration's Consequence Management Response Team (CMRT) deployed and took nearly 3 mo of measurements using airborne radiation sensors, fixed monitors, high purity germanium (HPGe) detectors, and health physics survey equipment...

Optical stimulated luminescence (OSL) combines reusability, sub-mm resolution, and a linear dose response in a single radiation detection technology. Such a combination is currently lacking in radiotherapy dosimetry. But OSL-films have a strong energy dependent response to keV photons due to a relative high effective atomic number (Z eff). The current work studied the applicability of a 2D OSL-film with a reduced Z eff as (IMRT/VMAT) dosimeter. Based on their commercial OSL-film experience, Agfa Healthcare N...

Interstitial lung diseases (ILDs) are a diverse group of pulmonary disorders characterized by various patterns of inflammation and fibrosis in the interstitium of the lung. The underlying pathogenesis of ILDs is complex and associated with multiple rheumatologic conditions, such as systemic sclerosis, rheumatoid arthritis, pollymyositis and dermatomyositis, Sjögren's syndrome, and systemic lupus erythematosus. As the disease progresses, excessive pulmonary fibrosis impairs alveolar gas exchange and damages pulmonary function...

PURPOSE: The 11-gauge (11G) stereotactic vacuum-assisted breast biopsy (VABB) showed a better profile than 14G-VABB in terms of feasibility, safety, microcalcification sampling, and accuracy. Underestimation rates were significantly lower with 11G-VABB than with 14G-VABB. Thus, the introduction of an even larger needle at the VABB procedure could reduce this rate further. The purpose of this study was to compare the overall performance of stereotactic VABB with 8G and 11G needles. MATERIALS AND METHODS: Four hundred and three VABBs performed between July 2012 and February 2015 at the Breast Diagnostic Unit of Careggi Hospital in Florence were retrospectively analyzed; 197 were performed with 11G-VABB and 206 with 8G-VABB...

Bacillus cereus is a widely-distributed, gram-positive or variable, rod-shaped bacterium frequently considered a contaminant in clinical specimens. It is recognized as a potential pathogen inducing self-limiting emetic or diarrheal food poisoning or localized infection in immunocompetent patients. True B. cereus bacteremia is uncommon and mainly observed in fragile patients, notably in immunocompromised individuals. We report clinical, radiological, and pathological findings of a 64-year-old patient with a history of acute myeloid leukemia who initially presented a fever while neutropenic after the induction of a second cycle of chemotherapy...

Everyday radiologists use dictation software to compose clinical reports of imaging findings. The dictation software is tailored for medical use and to the speech pattern of each radiologist. Over the past 10 years we have used dictation software to compose academic manuscripts, correspondence letters, and texts of educational exhibits. The advantages of using voice dictation is faster composition of manuscripts. However, use of such software requires preparation. The purpose of this article is to review the steps of adapting a clinical dictation software for dictating academic manuscripts and detail the advantages and limitations of this technique...

INTRODUCTION: Open reduction and internal fixation (ORIF) with plate and screws represents the recommended treatment for unstable intra-articular distal radius fractures. Although significant progresses in surgical technique have been made, anatomical reconstruction of radio-carpal articular surface still represent a difficult task, especially in multifragmentary fractures. Available PEEK reinforced-carbon fiber composite radiolucent devices allow both an easier and more careful assessment of intra-operative reduction of the articular surface of distal radius and prompt correction of any residual step deformity...

AIMS: Xanthogranulomatous cholecystitis (XGC), an unusual histologic variant of chronic cholecystitis, is characterized by mixed foamy histiocytic and lymphoplasmocytic infiltration and fibrosis. Radiologically, the poorly defined nodular growth pattern often leads to the misinterpretation of XGC as gallbladder cancer. In this study, we aimed to identify the relationship of XGC with IgG4-related cholecystitis, METHODS AND RESULTS: We re-evaluated 57 surgically resected XGCs and 104 conventional chronic cholecystitis cases, according to the histologic features observed in IgG4-related disease, including lymphoplasmocytic infiltration, storiform fibrosis, obliterative phlebitis, and IgG4-positive plasma cells...

OBJECTIVE: This article describes, illustrates, and correlates imaging and pathologic features of primary vascular mesenchymal neoplasms of the liver, which arise from the vascular endothelium and perivascular epithelioid cells. CONCLUSION: Familiarity with the spectrum of benign, malignant-potential and malignant vascular neoplasms, and nonneoplastic mimickers allows consideration in the differential diagnosis of enhancing hepatic masses. Understanding relevant pathologic features facilitates recognition of key imaging features, specifically dynamic contrast enhancement patterns on CT and MRI, which provide a useful classification system...

Interstitial lung disease (ILD) in pediatric patients is different from that in adults, with a vast array of pathologic conditions unique to childhood, varied modes of presentation, and a different range of radiologic appearances. Although rare, childhood ILD (chILD) is associated with significant morbidity and mortality, most notably in conditions of disordered surfactant function, with respiratory failure in 100% of neonates with surfactant protein B dysfunction and 100% mortality without lung transplantation...
