Radiological Investigation III: Pulmonary Angiogram and PET Scan01:13

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...

Imaging Studies II: Positron Emission Tomography and Scintigraphy

Positron Emission Tomography (PET) is a medical imaging technique that provides crucial insights into the body's physiological functions at a molecular level. It is an indispensable resource for diagnosing, staging, and monitoring various illnesses, notably cancer, neurological disorders, and cardiovascular conditions.
Fundamental Principles of PET
Positron Emission Tomography01:29

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...

Summary

Positron emission tomography (PET) shows promise for diagnosing and assessing sarcoidosis activity. This review explores PET

Area of Science:

  • Immunology
  • Radiology
  • Pulmonology

Background:

  • Sarcoidosis is a multisystem granulomatous disease with frequent pulmonary manifestations.
  • Diagnosis relies on clinical, radiological, and histological findings (noncaseating granulomas).
  • Current imaging techniques include radiography, CT, MRI, and Ga scintigraphy.

Purpose of the Study:

  • To discuss the potential utility of positron emission tomography (PET) in sarcoidosis.
  • To evaluate PET's role in diagnosis, disease activity assessment, and treatment planning.
  • To highlight the limitations of PET in managing sarcoidosis.

Main Methods:

  • Review of current literature on imaging modalities for sarcoidosis.
  • Focus on the application and limitations of positron emission tomography (PET).
