Positron Emission Tomography

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...

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.

Radiological Investigation III: Pulmonary Angiogram and PET Scan

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...

Background:

The clinical utility of (18)F-FDG PET in gynecologic malignancies is under-recognized.
Recent research is increasing focus on FDG PET's role in these cancers.

Purpose of the Study:

To review the current applications and potential of (18)F-FDG PET in gynecologic oncology.
To highlight the impact of FDG PET on patient management.

Main Methods:

Review of recent studies and literature on (18)F-FDG PET in gynecologic cancers.
Analysis of PET's sensitivity and specificity for various gynecologic malignancies.

Main Results:

FDG PET demonstrates high sensitivity and specificity for detecting relapse and nodal metastasis in cervical cancer.
Promising results are reported for endometrial cancer, uterine sarcomas, and ovarian cancer in staging and recurrence detection.
FDG PET has the potential to significantly alter patient management strategies.

Conclusions:

While FDG PET shows significant potential in gynecologic oncology, its optimal role requires further investigation.
Ongoing studies aim to refine the application of FDG PET for improved patient outcomes.
