Coronary artery fistula (CAF) is a rare anomaly that originates from the coronary artery and drains into the cardiac chamber or the adjacent vasculature. We report a case of CAF in a 77 years old woman with dyspnea on exertion. Using coronary angiography and cardiac multidetector computed tomography, this patient was diagnosed with CAF draining into the left bronchial arteries. First-pass radio...

Anomalous left coronary artery from pulmonary (ALCAPA) is a rare congenital anomaly with high rate of mortality in first year life. It one the most common causes cardiomyopathy and myocardial ischemia children. In present scenario, computed tomography (CT) angiography sufficient for diagnosis ALCAPA, eliminating need invasive angiography. CT performed infants suspicion ALCAPA technically challe...

The diagnosis of pulmonary embolism may be confounded by a clinical presentation that is often subtle or atypical. Therefore pulmonary angiography, although invasive, has been widely used to prove pulmonary embolism. The aim of this review is to discuss the value of non-invasive techniques, such as lung scan and chest computed tomography scan, in the diagnosis of pulmonary embolism. Ventilation...

PURPOSE OF REVIEW The purpose of this review is to focus on recent research that has addressed the relative merits of computed tomographic pulmonary angiography (CTPA) and ventilation perfusion (V/Q) scanning for the diagnosis of pulmonary embolism. RECENT FINDINGS Computed tomographic pulmonary angiography is the most sensitive test for the diagnosis of pulmonary embolism and its use has bee...

INTRODUCTION Although the advent of multi-detector row computed tomography (CT) has enabled better visualization of subsegmental pulmonary (SSP) arteries, SSP embolism is of uncertain clinical significance. We aimed at answering the following questions: Is spiral CT an accurate method to detect SSP embolism? How are subsegmental perfusion defects managed in outcome studies including spiral CT? ...

showed multiple ill-defined increased densities in both lower lung fields. High-resolution computed tomography was then performed and showed ill-defined, wedge-shaped increased densities with patent airways in the posterior subpleural regions of both lower lobes. The computed tomography differential diagnosis was organising pneumonia, bronchopneumonia, Churg–Strauss syndrome, Wegener granulomat...
