The article offers guidelines for interpretation of chest radiographs of the critically ill patients in intensive care units (ICUs). Particular focus is given to cardiopulmonary disorders diagnosed through chest radiographs. The normal position of monitoring devices and other line placements, including the endotracheal tube, nasogastric tube and pulmonary capillary wedge pressure monitors, are described. The definitions and characterizations of cardiopulmonary disorders including pneumothorax, pneumomediastinum and pleural effusions are provided.

With increased exposure of patients to routine imaging, incidental benign intrathoracic masses are frequently recognized. Most have classical imaging features, which are pathognomonic for their benignity. The aim of this pictorial review is to educate the reader of radiological features of several types of intrathoracic masses. The masses are categorized based on their location/origin and are grouped into parenchymal, pleural, mediastinal, or bronchial. Thoracic wall masses that invade the thorax such as neurofibromas and lipomas are included as they may mimic intrathoracic masses. All examples are illustrated and include pulmonary hamartoma, pleural fi broma, sarcoidosis, bronchial carcinoid, and bronchoceles together with a variety of mediastinal cysts on plain radiographs, computed tomography (CT) and magnetic resonance imaging (MRI). Sometimes a multimodality approach would be needed to confi rm the diagnosis in atypical cases. The study would include the incorporation of radionuclide studies and relevant discussion in a multidisciplinary setting. [ABSTRACT FROM AUTHOR]

Intra-thoracic manifestations of progressive systemic sclerosis (PSS) are not well known particularly the imaging features, which forms the basis of accurate and timely diagnosis. The aim of this study is to familiarize the physicians and radiologists with these features. The diagnosis can remain elusive because of the non-specifi c nature of symptoms which mimic many common conditions. Thus, the diagnosis of PSS can be missed leading to continuous morbidity if the correct imaging is not pursued. The authors examined the records of rheumatology patient referrals of over a 5 year period. A hundred and seventy patients with systemic sclerosis and mixed connective tissue disorders were chosen for detailed study of the imaging available, which form the basis of this review. The images included conventional chest radiographs, digital radiographs computed radiography (CT) and high resolution computed tomography (HRCT). Where applicable computed pulmonary angiography (CTPA) and radionuclide scans were also interrogated. [ABSTRACT FROM AUTHOR]
