Preoperative evaluation of colorectal liver metastases: comparison between gadoxetic acid-enhanced 3.0-T MRI and contrast-enhanced MDCT with histopathological correlation

Abstract

• Potential surgical treatment requires accurate radiological assessment of colorectal liver metastases • Magnetic resonance imaging with gadoxetic acid is the preferred imaging investigation. • MRI is better than multidetector CT for detecting small liver metastases.

Managing synchronous liver metastases from colorectal cancer: A multidisciplinary international consensus

“…The best methods for staging are CT and MRI. A review of the literature indicates that MRI is more sensitive than CT for subcentimetre liver lesions [21] and after neoadjuvant chemotherapy [22], and that a thoraco-abdominal CT is the best option for initial staging [12]. Appraisal of published methods shows that a quadri/triphasic technique, optimal contrast administration and scanning parameters providing high spatial and contrast resolution show superior CT accuracy than generally reported in the literature [23][24][25]22].…”

Potential of MR histogram analyses for prediction of response to chemotherapy in patients with colorectal hepatic metastases

“…The prognosis of colorectal liver metastases mainly depend on the progression of liver metastases. In patients with resectable colorectal liver metastasis (CLM), preoperative MR imaging have the potential to improve the detection of lesions and to determine the correct therapeutic strategy [2,3], which may lead to better prognosis and survival. However, the majority of patients with CLM are not suitable for resection due to the size, location, extent of disease, etc.…”

Routine Preoperative Liver-specific Magnetic Resonance Imaging Does Not Exclude the Necessity of Contrast-enhanced Intraoperative Ultrasound in Hepatic Resection for Colorectal Liver Metastasis

“…12,13 This technique enables not only a dynamic study evaluating tumor vascularity but also liver-specific imaging, with the contrast agent being taken up by the hepatic cells. Because conventional dynamic MRI itself is reportedly superior to CE-CT for demonstrating and characterizing liver tumors, 14 EOB-MRI, which enables more than just a dynamic study, is considered to be a highly sensitive imaging modality, 13,15,16 being expected to become the gold standard for the detection of CRLMs in the near future. 17 We assumed that CE-IOUS would be of limited value or even omissible if EOB-MRI were to be performed preoperatively.…”
