Summary
Accurate detection of peritoneal carcinomatosis is challenging for imaging, impacting treatment selection. Enhanced imaging and radiologist expertise are vital for effective patient management and surgical planning.
Area of Science:
- Radiology
- Oncology
- Surgical Oncology
Background:
- Peritoneal carcinomatosis detection is challenging despite advanced imaging.
- Underestimation of disease burden can occur due to limitations in detecting small implants.
- Effective treatment relies on accurate staging and surgical planning.
Purpose of the Study:
- To review the role of imaging in evaluating peritoneal carcinomatosis.
- To highlight the importance of accurate disease assessment for treatment selection.
- To emphasize the collaboration between radiologists and surgeons.
Main Methods:
- Review of contrast-enhanced multidetector computed tomography (MDCT) as the standard.
- Discussion of magnetic resonance imaging (MRI) for complementary data.
- Evaluation of positron emission tomography (PET) for extraperitoneal involvement.
Main Results:
- MDCT is the primary imaging modality for peritoneal carcinomatosis.
- MRI provides valuable supplementary information.
- PET is mainly indicated for detecting unsuspected extraperitoneal disease in specific neoplasms.
Conclusions:
- Accurate imaging is critical for patient selection for cytoreductive surgery and intraperitoneal chemotherapy.
- Radiologist expertise and surgeon-radiologist collaboration are essential.
- Continued advancements in imaging are needed to improve detection of peritoneal surface disease.
