SALINE MR PERITONEOGRAPHY

OBJECTIVE. Our objective was to describe a new method for the evaluati on of peritoneal surfaces in patients with intraperitoneal carcinomato sis and sarcomatosis. CONCLUSION. Fast spin-echo T2-weighted imaging i n conjuction with intraperitoneally instilled saline permits detailed evaluation of peritoneal surfaces, omentum, and mesenteries. The detec tion of tumor implants is facilitated by their visualization against t he saline background. Additionally, normal and abnormal saline distrib ution patterns can be identified. This technique may also be useful in predicting response to intraperitoneally instilled chemotherapy.
