Abstract:
Amyloidosis is a disease caused by the deposition of abnormal proteins within extracellular soft tissues, and affects the respiratory tract in 50% of cases. Pulmonary involvement may be secondary to systemic disease or due to the accumulation of locally produced amyloid, and this differentiation has important prognostic and therapeutic implications. This pictorial essay, using cases of biopsy-proven respiratory tract amyloidosis, aims to depict the spectrum of imaging findings, and those of CT in particular, that can be of use in distinguishing between the 2 typical patterns of the disease.

Radiological Investigation III: Pulmonary Angiogram and PET Scan
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...
