Abstract:
An 80-year-old woman, under neurology follow-up for cognitive decline, presented with progressive memory loss, episodes of disconnection and occasional loss of impulse control. Brain CT scan revealed findings consistent with Fahr syndrome. In addition, an 18 F-FDG PET/CT was performed to assess cognitive deterioration. This case illustrates characteristic PET/CT imaging findings of a rare condition.

Radiological Investigation III: Pulmonary Angiogram and PET Scan
642
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...

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...
