Summary
This summary is machine-generated.18F-FES PET/CT demonstrated high accuracy in detecting distant metastasis or recurrence in estrogen receptor-positive breast cancer patients. This imaging technique offers superior detection rates compared to standard methods for ER-positive breast cancer staging.
Area Of Science
- Oncology
- Nuclear Medicine
- Radiology
Background
- Estrogen receptor (ER)-positive breast cancer accounts for a significant proportion of breast cancer cases.
- Accurate detection of distant metastasis and recurrence is crucial for effective treatment planning and patient outcomes.
- Standard imaging modalities may have limitations in detecting small or widespread metastatic lesions.
Purpose Of The Study
- To assess the diagnostic performance of 16α-18F-fluoro-17β-fluoroestradiol (18F-FES) PET/CT.
- To evaluate its utility in identifying distant metastasis or recurrence in patients with ER-positive breast cancer.
- To compare the detection rate of 18F-FES PET/CT with standard-of-care imaging.
Main Methods
- Retrospective analysis of patients with ER-positive breast cancer and suspected metastasis or recurrence.
- Inclusion of patients from a prospective postmarketing surveillance study of 18F-FES PET/CT.
- Diagnostic accuracy assessed against pathology or standard imaging with a minimum 6-month follow-up.
Main Results
- Overall sensitivity and specificity of 18F-FES PET/CT were 95% and 89%, respectively.
- High sensitivity (95%) and specificity (96%) were observed for detecting recurrence.
- 18F-FES PET/CT showed a significantly higher detection rate (92%) compared to standard imaging (83%) per region.
Conclusions
- 18F-FES PET/CT exhibits excellent diagnostic performance for ER-positive breast cancer.
- The imaging modality is valuable for detecting distant metastasis and recurrence.
- It offers improved detection capabilities over conventional imaging methods.

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...
Positron Emission Tomography (PET) is a medical imaging technique that provides crucial insights into the body's physiological functions at a molecular level.

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...
