Abstract:
This article provides a review of the latest radiotracers for planar/single-photon emission computed tomography (SPECT) and positron emission tomography (PET)/computed tomography (CT) imaging of cardiac amyloidosis, detailing their affinity, specificity, and sensitivity for cardiac amyloidosis. There are several tracers available that have differing affinities for transthyretin (ATTR) and immunoglobulin light chain (AL), and new developments in technology have allowed for disease burden quantification. Bone scintigraphy is an excellent option for visualizing ATTR cardiac amyloidosis. Negative testing does not exclude the possibility of AL cardiac amyloidosis and absolute quantitation of amyloid burden is limited.

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...
