Inter-observer agreement in identifying traction bronchiectasis on computed tomography: its improvement with the use of the additional criteria for chronic fibrosing interstitial pneumonia.

Purpose: To assess inter-observer variability in identifying traction bronchiectasis on computed tomography (CT) using additional criteria for chronic fibrosing interstitial pneumonia.

Methods: Seven experts categorized CT image set representing 39 patients into three groups on the basis of the presence of traction bronchiectasis, using a three-point scale: 3-definitely/probably yes; 2-possibly yes; and 1-definitely/probably no. This scale served as a reference standard.

Tree-in-Bud Pattern of Pulmonary Tuberculosis on Thin-Section CT: Pathological Implications.

The "tree-in-bud-pattern" of images on thin-section lung CT is defined by centrilobular branching structures that resemble a budding tree. We investigated the pathological basis of the tree-in-bud lesion by reviewing the pathological specimens of bronchograms of normal lungs and contract radiographs of the post-mortem lungs manifesting active pulmonary tuberculosis. The tree portion corresponds to the intralobular inflammatory bronchiole, while the bud portion represents filling of inflammatory substances within alveolar ducts, which are larger than the corresponding bronchioles.

Sequential morphological changes in follow-up CT of pulmonary mucormycosis.

Purpose: We aimed to describe the computed tomography (CT) features of pulmonary mucormycosis including sequential changes between follow-ups.

A new classification of adenocarcinoma: what the radiologists need to know.

The International Association for the Study of Lung Cancer, American Thoracic Society, and European Respiratory Society recently introduced a new classification of lung adenocarcinoma addressing the latest advances in oncology, molecular biology, pathology, radiology, and surgery of lung adenocarcinoma. In this classification, new uniform terminology and diagnostic criteria are described, including the introduction of adenocarcinoma in situ as a second preinvasive lesion, as well as the concept of minimally-invasive adenocarcinoma and new subtyping of invasive adenocarcinomas stratified according to predominant patterns. In addition, the previously widely-used term bronchioloalveolar carcinoma is no longer considered valid and has been recategorized.

Computed tomography features of extensively drug-resistant pulmonary tuberculosis in non-HIV-infected patients.

Objective: To describe the computed tomography (CT) findings of pulmonary extensively drug-resistant tuberculosis (XDR-TB) in non-HIV-infected patients and to compare them with those of non-XDR multidrug-resistant tuberculosis (MDR-TB).

Methods: Retrospective review of microbiological results and drug-susceptibility tests of 260 non-HIV-infected patients who had been diagnosed with pulmonary MDR-TB from 1994 to 2005 revealed that 47 patients had XDR-TB, whereas the other 213 patients had non-XDR MDR-TB. Twenty of the 47 XDR-TB patients and 85 of the 213 non-XDR MDR-TB patients with available CT examinations were included in this study.

Vision of the korean association of medical colleges.

The Korean Association of Medical Colleges (KAMC) has launched as a corporate aggregate in August 2008, since the inauguration meeting as "Korean Association of Medical School Deans" 24 years before. The mission of KAMC is to be the representing agency of medical education in Korea, producing policies and strategies, suggesting and influencing government agencies related to medical education. The KAMC will consolidate its basic role and continue to expand its role as well; evaluation of basic medical education, representative of graduate medical education, policy making of medical manpower education system.

Radiation dose modulation techniques in the multidetector CT era: from basics to practice.

Radiation exposure to the patient has become a concern for the radiologist in the multidetector computed tomography (CT) era. With the introduction of faster multidetector CT scanners, various techniques have been developed to reduce the radiation dose to the patient; one method is automatic exposure control (AEC). AEC systems make use of different types of control, including patient-size AEC, z-axis AEC, rotational or angular AEC, or a combination of two or more of these types.
