Endoscopic Ultrasound-Guided Fine Needle Aspiration has High Diagnostic Value in the Diagnosis of Solid Pancreatic Lesions.

Objective: To analyze the potential factors influencing the diagnostic capability of endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) and provide medication treatment recommendations for patients with pancreatic solid mass lesions.

Methods: A retrospective analysis was conducted on clinical data of 92 patients with pancreatic solid mass lesions who underwent EUS-FNA examination after detection by imaging studies. The diagnostic effectiveness of EUS-FNA was evaluated based on cytological or histological examination results.

Illustration of a number of atypical computed tomography manifestations of active pulmonary tuberculosis.

Tuberculosis is a serious public health challenge facing mankind and one of the top ten causes of death. Diagnostic imaging plays an important role, particularly for the diagnosis and treatment planning of tuberculosis patients with negative microbiology results. This article illustrates a number of atypical computed tomography (CT) appearances of pulmonary tuberculosis (PTB), including (I) clustered micronodules (CMNs) sign; (II) reversed halo sign (RHS); (III) tuberculous pneumatocele; (IV) hematogenously disseminated PTB with predominantly diffuse ground glass opacity manifestation; (V) hematogenously disseminated PTB with randomly distributed non-miliary nodules; (VI) PTB changes occur on the background of emphysema or honeycomb changes of interstitial pneumonia; and (VII) PTB manifesting as organizing pneumonia.

[Quantitative comparison of idiopathic interstitial pneumonias on high-resolution computed tomographic findings].

Objective: To analyze the high-resolution computed tomographic (HRCT) findings of IPF (interstitial pulmonary fibrosis), NSIP (nonspecific interstitial pneumonia) and COP (cryptogenic organizing pneumonia) retrospectively through quantification methods and to explore their distinguishing features.

Methods: Observers with no prior knowledge of the diagnosis evaluated the frequency, extent and distribution of various thin-section CT findings in 29 males and 17 females. The mean age was 50 ± 10 years old (range: 25 - 76).

Clinical features of pneumonia caused by 2009 influenza A(H1N1) virus in Beijing, China.

Background: Data on symptoms and radiographic changes in patients with pandemic 2009 influenza A(H1N1) (A[H1N1]) pneumonia during convalescence have not been reported.

Methods: During October 26, 2009, and January 23, 2010, adult patients with pneumonia with laboratory-confirmed or clinically suspected A(H1N1) infections were observed for clinical characteristics, high-resolution chest CT scan, and lung function test changes during acute and 3-month convalescent phases.

Results: Of the 65 case subjects, the median age was 41 (interquartile range [IQR], 28-57) years, 60.
