Abstract:
We report a case of an 8-year-old boy with a history of aortopexy for aortic compression and multiple venous thrombosis. A 64-slice multidetector-row computed tomography examination was performed to evaluate the cause of esophageal varices and the extent of previously reported thrombi. Despite extremely low radiation dose settings, the 64-slice computed tomography angiography was fully diagnostic and showed discontinuity of the superior vena cava and brachiocephalic veins. In addition, the azygous system and large collateral vessels across the anterior, medial, and posterior mediastinum and chest wall were observed. This case shows that in pediatric patients complicated vascular pathology can reliably be assessed and radiation exposure can be safely minimized.

Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...

Definition and Purpose
An X-ray, or radiograph, is a non-invasive method that uses ionizing radiation to take images of internal structures. It is mainly used in cardiac imaging to examine the heart, lungs, and major blood vessels, aiming to identify abnormalities in the heart's size, shape, and position, such as heart failure, congenital defects, and vascular...

Radiological Investigation II: MRI and Ventilation Perfusion Scan
Magnetic Resonance Imaging (MRI) and Ventilation Perfusion Scans are two radiological investigations that offer detailed diagnostic images of the body, particularly lung structures.
MRI
MRI uses magnetic fields and radiofrequency signals to distinguish between normal and abnormal tissues. This technology provides a more detailed diagnostic image than CT scans, enabling it to characterize pulmonary nodules, stage bronchogenic carcinoma, and evaluate inflammatory activity in...
