Objective:
Our objective was to describe a new method for the evaluation of peritoneal surfaces in patients with intraperitoneal carcinomatosis and sarcomatosis.
Conclusion:
Fast spin-echo T2-weighted imaging in conjuction with intraperitoneally instilled saline permits detailed evaluation of peritoneal surfaces, omentum, and mesenteries. The detection of tumor implants is facilitated by their visualization against the saline background. Additionally, normal and abnormal saline distribution patterns can be identified. This technique may also be useful in predicting response to intraperitoneally instilled chemotherapy.
