CT demonstration of peritoneal metastases after intraperitoneal injection of contrast media

Peritoneal carcinomatosis from colorectal or appendiceal origin: Correlation of preoperative CT with intraoperative findings and evaluation of interobserver agreement

“…CT with intraperitoneal contrast media was initially used to study fluid dynamics and subsequently applied to the detection of peritoneal metastases. In ovarian cancer patients, intraperitoneal administration of contrast material seems to improve the sensitivity of CT in preoperative detection of these lesions [34][35][36][37]. However, this technique failed to detect flat peritoneal metastases, and had a low specificity in patients with a history of prior abdominal surgery [34].…”

Induced pueumoperitoneum in CT evaluation of peritoneal carcinomatosis

“…The results published in the literature show that the general sensitivity of CT in terms of presence or absence of disease can be improved with this method and also that the specificity is high. Giunta et al [4] and Halvorsen et al [1] found a sensitivity of 100% for CTIP in the detection of peritoneal carcinomatosis. However, it is desirable to know not only if the disease is present in a particular examination but also its exact extent, as pointed out by Nelson et al [5].…”

“…Several studies reported a better sensitivity of CT when performed with this method [1,4] but its clinical usefulness was recently questioned in a retrospective study [5].…”

Detecting peritoneal dissemination of ovarian cancer in mice by DWIBS

“…Such random peritoneal tumors are difficult to detect in conventional anatomical magnetic resonance imaging (MRI) or computed tomography (CT) due to poor differentiation of the tumor from the surrounding organs and small tumor size [2,3]. Accordingly, the imaging tools that can provide functional information of the tumor have been suggested to be more effective.…”
