Coronary artery calcium score: current status.

The coronary artery calcium score plays an Important role In cardiovascular risk stratification, showing a significant association with the medium- or long-term occurrence of major cardiovascular events. Here, we discuss the following: protocols for the acquisition and quantification of the coronary artery calcium score by multidetector computed tomography; the role of the coronary artery calcium score in coronary risk stratification and its comparison with other clinical scores; its indications, interpretation, and prognosis in asymptomatic patients; and its use in patients who are symptomatic or have diabetes.

Coronary anomalies: what the radiologist should know.

Coronary anomalies comprise a diverse group of malformations, some of them asymptomatic with a benign course, and the others related to symptoms as chest pain and sudden death. Such anomalies may be classified as follows: 1) anomalies of origination and course; 2) anomalies of intrinsic coronary arterial anatomy; 3) anomalies of coronary termination. The origin and the proximal course of anomalous coronary arteries are the main prognostic factors, and interarterial course or a coronary artery is considered to be malignant due its association with increased risk of sudden death.

High-resolution computed tomography findings in hantavirus pulmonary syndrome.

The hantavirus pulmonary syndrome (HPS) is an acute, rapidly progressive disease transmitted by rodent excreta, with endothelial damage playing a central role in the pathophysiology. It usually affects rural workers. The lung itself is the target organ and reflects all the patterns of endothelial involvement of this disease.

Chronic myelopathy associated to intramedullary cysticercosis.

Study Design: Case report.

Objective: Discuss an isolated intramedullary neurocysticercosis (NCC) case in an adult patient with chronic progressive onset myelopathic symptomatology with clinical, radiologic, and pathologic correlation.

Summary Of Background Data: NCC is the most common parasitic infection in the central nervous system.
