Pleura, Chest Wall, and Diaphragm
Technical Considerations In general, the pleura and chest wall are adequately evaluated with routine thoracic CT techniques. Contrast medium infusion is helpful in showing pleural thickening and in allowing its…
GENERAL RADIOLOGY
Mediastinum: Vascular Abnormalities and Pulmonary Embolism
Aortic Abnormalities Computed tomography (CT) is commonly used to diagnose abnormalities of the aorta or its branches when they are suspected clinically or because of radiographic abnormalities. Congenital Anomalies Congenital…
Mediastinum: Lymph Node Abnormalities and Masses
Lymph Node Groups Mediastinal lymph nodes are generally classified by location. Most descriptive systems are based on a modification of Rouvière’s classification of lymph node groups. The names used in…
Introduction to CT of the Abdomen and Pelvis
Despite marked advances in limiting image times for magnetic resonance imaging, CT remains the primary modality for most indications for imaging the abdomen and pelvis. The technology of multidetector CT…
Mediastinum: Introduction and Normal Anatomy
Computed tomography (CT) is commonly used in patients suspected of having a mediastinal mass or vascular abnormality (e.g., an aortic aneurysm). In general, CT is performed in two situations. First,…
Introduction to CT of the Thorax: Chest CT Techniques
S piral (helical) computed tomography (CT) allows the entire chest to be imaged in a few seconds or less (i.e., during a single breath hold), with volumetric acquisition of scan…
Imaging of Cardiac Support Devices
Patients hospitalized in the intensive care unit (ICU) often have multiple support lines and devices that need routine imaging evaluation by radiologists. In patients with cardiogenic shock or depressed cardiac…
Neuroimaging of Patients in the Intensive Care Unit
A brief introduction is provided of the different imaging modalities encountered in the intensive care unit (ICU). The spectrum of intracranial pathology as well as potential postsurgical complications is reviewed,…
Imaging Early Postoperative Complications of Cardiothoracic Surgery
Imaging plays a central role in the evaluation of patients following cardiothoracic surgery, both for monitoring in the early postoperative period and for assessing for suspected complications. Patients with postsurgical…
Imaging of Altered Mental Status
Neuroimaging is an invaluable diagnostic tool for sorting through the vast array of etiologies that underlie altered mental status (AMS). Head computed tomography (CT) without contrast is the primary modality…
