Abstract:

An immunohistochemical study demonstrates that most of the cholangiocarcinomas have PSMA expression in the tumor neovasculature. PSMA PET findings of cholangiocarcinomas are rarely reported. We describe 68Ga-PSMA-11 PET/CT and delayed abdominal 68Ga-PSMA-11 PET/MRI findings in a case of mass-forming type of perihilar cholangiocarcinoma. The tumor showed intense PSMA uptake with SUVmax of 10.8 on 68Ga-PSMA-11 PET/CT and SUVmax of 7.8 on delayed 68Ga-PSMA-11 PET/MRI.

Positron Emission Tomography

Positron emission tomography (PET) is a medical imaging technique involving radiopharmaceuticals — substances that emit short-lived radiation. Although the first PET scanner was introduced in 1961, it took 15 more years before radiopharmaceuticals were combined with the technique and revolutionized its potential.
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 being...

Radiological Investigation III: Pulmonary Angiogram and PET Scan

Radiological investigations are paramount in the diagnosis and management of various pulmonary diseases. Two essential investigations are the Pulmonary Angiogram and the Positron Emission Tomography (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...
