Positron Emission Tomography01:29

Positron Emission Tomography

7.9K
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...

Computed Tomography

Tomography refers to imaging by sections. Computed tomography (CT) is a non-invasive imaging technique that uses computers to analyze several cross-sectional X-rays to reveal minute details about structures in the body.
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...

Radiological Investigation III: Pulmonary Angiogram and PET Scan

600
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...

Area of Science:

  • Oncology
  • Radiology
  • Nuclear Medicine

Background:

  • Positron emission tomography/Computed tomography (PET/CT) is a widely utilized imaging modality in the management of gynecologic cancers.
  • Determining the optimal timing and application of PET/CT in gynecologic oncology is crucial for effective patient care.

Purpose of the Study:

  • To establish guidelines for the appropriate use of PET/CT in the diagnosis and management of gynecologic cancers.
  • To delineate the specific clinical scenarios where PET/CT offers significant advantages.

Main Methods:

  • A comprehensive literature review of PubMed was conducted, focusing on PET/CT applications in all gynecologic cancers.
  • Relevant clinical guidelines from the National Comprehensive Cancer Network, Society of Gynecologic Oncology, and American College of Radiology were systematically reviewed.

Main Results:

  • Whole-body PET/CT is beneficial for initial staging of cervical and endometrial cancers.
  • PET/CT is indicated for post-therapy assessment, radiation therapy planning, and surveillance of cervical cancer.
  • The modality is valuable for assessing recurrence in cervical, endometrial, and ovarian cancers, particularly with symptoms.
  • PET/CT is also useful for staging and recurrence evaluation of uterine sarcomas, and for staging vulvar and vaginal cancers.

Conclusions:

  • Positron emission tomography/Computed tomography (PET/CT) demonstrates significant clinical value across a spectrum of gynecologic cancers.
  • PET/CT plays a pivotal role in the initial detection of disease and the identification of recurrence in gynecologic malignancies.
