Abstract:
Systemic AL (amyloid light-chain) amyloidosis is a relatively rare disease. 99m Tc-DPD (3,3-diphosphono-1,2-pyrophosphate) bone scan is a highly sensitive diagnostic tool for cardiac amyloidosis of ATTR (transthyretin) type. In AL amyloidosis, there have been some previous reports of extracardiac DPD uptake in liver, kidney, and spleen, but not in stomach. We present 99m Tc-DPD bone scan images of AL-type amyloidosis involving stomach and lung.

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...
Positron Emission Tomography
One of the main requirements of a PET scan is a positron-emitting radioisotope, which is produced in a cyclotron and then attached to a substance used by the part of the body...
