Summary
This summary is machine-generated.Magnetic resonance imaging (MRI) and fluorodeoxyglucose positron emission tomography/computed tomography (FDG PET/CT) show higher sensitivity for detecting peritoneal metastases in ovarian cancer compared to multidetector CT (MDCT). Further research is needed to clarify their comparative value.
Area Of Science
- Oncology
- Radiology
- Diagnostic Imaging
Background
- Peritoneal metastases (PMs) are a common complication of ovarian cancer (OC).
- Accurate detection of PMs is crucial for staging and treatment planning in OC.
- Multidetector CT (MDCT), MRI, and FDG PET/CT are utilized for PM detection, but their comparative performance is not fully established.
Purpose Of The Study
- To compare the diagnostic performance of MDCT, MRI (including diffusion-weighted imaging), and FDG PET/CT in detecting PMs in OC.
- To evaluate the sensitivity and specificity of each imaging modality for PM detection.
Main Methods
- A systematic review and meta-analysis of studies published between 2000 and February 2023.
- Inclusion criteria focused on studies evaluating MDCT, MRI, and/or FDG PET/CT for PM detection in OC patients, with surgical/histopathologic confirmation as the reference standard.
- Data extraction included per-patient and per-region sensitivity and specificity for each modality.
Main Results
- 33 studies involving 487 women with OC and PMs were analyzed.
- On a per-patient basis, MRI and FDG PET/CT demonstrated significantly higher sensitivity than MDCT (p < 0.05).
- MRI and FDG PET/CT showed comparable sensitivities (p = 0.84), and no significant differences in per-lesion sensitivity were found between any of the modalities.
Conclusions
- FDG PET/CT and MRI are preferred imaging modalities for detecting PMs in OC due to higher per-patient sensitivity compared to MDCT.
- Further research is required to determine the precise comparative value of FDG PET/CT and MRI over MDCT.
- Future studies should address existing limitations, focus on standardization, and explore cost-effectiveness.

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...
