Insights

Glucagon analog reduces digestive peristalsis artifacts in abdominal MRI. Its use in FDG PET/MRI was evaluated for potential FDG metabolism interaction, with findings reported.

Area of Science:

  • Medical imaging
  • Radiology
  • Nuclear medicine

Background:

  • Digestive peristalsis causes artifacts in abdominal and pelvic MRI, hindering interpretation.
  • Glucagon analog is used to reduce peristalsis and MRI artifacts, but its effect on FDG PET/MRI is unknown.

Purpose of the Study:

  • To assess the interaction between glucagon analog and FDG metabolism in PET/MRI.
  • To evaluate the impact of glucagon analog on FDG PET/MRI image quality.

Main Methods:

  • FDG PET/MRI scans were acquired in patients with and without glucagon analog administration.
  • Image quality and potential metabolic changes were analyzed.

Main Results:

  • Glucagon analog effectively reduced digestive peristalsis artifacts.
  • No significant adverse interaction with FDG metabolism was observed, preserving image quality.

Conclusions:

  • Glucagon analog can be safely used in conjunction with FDG PET/MRI.
  • It improves image quality by reducing motion artifacts without compromising metabolic information.

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...

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...
