Imaging challenges in peritoneal malignancy persist despite technological advances. This review covers CT, MRI, and PET/CT for detecting peritoneal tumors, aiding diagnosis and surveillance.
Area of Science:
- Radiology
- Oncology
- Medical Imaging
Background:
- Peritoneal malignancy diagnosis is challenging due to complex anatomy and overlapping disease appearances.
- Contrast-enhanced multidetector computed tomography (MDCT) is a versatile tool, but limitations exist.
Purpose of the Study:
- To review established and novel imaging techniques for peritoneal malignancy.
- To provide an overview of peritoneal anatomy, function, and disease dissemination patterns.
Main Methods:
- Review of contrast-enhanced multidetector computed tomography (MDCT).
- Evaluation of conventional and emerging magnetic resonance imaging (MRI) techniques.
- Assessment of positron emission tomography (PET)/CT for peritoneal malignancy detection and surveillance.
Main Results:
- MDCT is versatile but has limitations in peritoneal malignancy assessment.
- MRI and PET/CT offer significant advantages over MDCT for detection and surveillance.
- Common sites and imaging features of peritoneal malignancy are illustrated.
Conclusions:
- Advanced imaging techniques like MRI and PET/CT enhance peritoneal malignancy detection and surveillance.
- Understanding peritoneal anatomy and disease spread is crucial for accurate interpretation.
- This review aids clinicians in selecting appropriate imaging modalities for peritoneal pathology.
