Peritoneal tumor: MR imaging with dilute oral barium and intravenous gadolinium-containing contrast agents compared with unenhanced MR imaging and CT.

Abstract

Double-contrast MR imaging demonstrated more peritoneal tumors than CT or unenhanced spin-echo MR imaging.

Role of Imaging in Peritoneal Surface Malignancies

“…MRI is comparable to CT in several aspects, in detecting deposits of more than 1 cm [18]. The use of fat suppression, delayed post contrast enhancement and water soluble enteric contrast have allowed detection sensitivities to surpass CT [20] Peritoneal enhancement more than liver enhancement is abnormal and is visualised due to the superior contrast resolution-a sign that may not be readily appreciated on MDCT. [18] MRI is more sensitive that CT for subcentimetric sized deposits and also in anatomically difficult sites (e.g.…”

Assessment of Relapse in Patients with Peritoneal Carcinomatosis after Cytoreductive Surgery and Hyperthermic Intraperitoneal Chemotherapy using F-18-FDG-PET/CT

“…Recent developments in patient treatment include total peritonectomy and multivisceral resection of all involved tissue combined with hyperthermic intraperitoneal chemotherapy (HIPEC) as an approach with curative intention [4 -6]. Several imaging modalities are used in the preoperative assessment of tumor extent including ultrasound [7], computed tomography (CT) [8,9], magnetic resonance imaging (MRI) [10,11] as well as F-18-FDG positron emission tomography/computed tomography (PET/CT) [9, 12,13]. Recent studies indicate good results especially for MRI and PET/CT due to its potential of functional and morphological tissue characterization [10,11].…”

Recent studies indicate good results especially for MRI and PET/CT due to its potential of functional and morphological tissue characterization [10,11]. The assessment of recurring PC after HIPEC is even more challenging than the preoperative evaluation as peritonectomy and HIPEC come along with extensive postoperative tissue alterations often accompanied by inflammatory reaction after HIPEC.…”
