In this project, there is only one study group which comprises of patients with Hepatocellular Carcinoma (HCC) who will undergo Liver MRI with Primovist before hepatic transplantation.

Utility of Gd-EOB-DTPA (Primovist) enhanced Liver MRI in HCC detection and characterization in cirrhotic patients will be studied.

Chronic liver disease including cirrhosis is one of the most important factors in the multi-step progression of hepatocarcinogenesis, from benign regenerative nodules to early hepatocellular carcinomas (HCCs) and finally to overt HCCs. Early diagnosis of HCC, differentiation from benign hepatocellular nodules, and surgical resection of the tumor or transplantation of the liver provide the best chance for long-term survival. Several studies have evaluated MRI enhanced with superparamagnetic iron oxide, gadolinium-based contrast material, or both, for the detection and differential diagnosis of focal hepatic lesions. However, the differentiation of HCC from benign and or borderline hepatocellular nodules remains difficult, particularly in patients with cirrhosis, because of the architectural distortion of liver parenchyma and the development of cirrhotic nodules, ranging from benign regenerative nodules to overt HCC, with overlapping imaging features. Recently, gadoxetic acid (gadoliniumethoxybezyl-diethylenetriamine pentaacetic acid; Primovist®, Bayer Health Care Pharmaceuticals), a gadolinium-based paramagnetic contrast agent that produces both dynamic and liver-specific hepatobiliary MRI studies has gained widespread use. Some studies have showed that gadoxetic acid-enhanced MRI allows the accurate detection and characterization of HCC. Investigators plan to assess this in particular as it is a question of great relevance. Execution of well conducted prospective studies will also clarify inclusion of Gd-EOB-DTPA enhanced MRI as the technique of choice in evaluation of patients at risk for HCC.

The first group consists of patients with colorectal liver metastases who have had treatment with chemotherapy and are now awaiting surgery. This group would have had Multidetector Liver CT (MDCT) imaging prior to the chemotherapy, and will now undergo post chemotherapy MDCT as part of standard clinical care in addition to Gd-EOB-DTPA enhanced liver MRI and Diffusion Weighted MRI (DW-MRI). The MRI will be performed as an additional imaging investigation after obtaining informed consent.

The second group consists of patients with colorectal liver metastases who are due to receive neoadjuvant chemotherapy. This group will be imaged prior to receiving and after receiving chemotherapy. This will all be done prior to surgical resection of their colorectal liver metastases.

MR imaging

1. Primovist-enhanced Magnetic resonance imaging (MRI) and Diffusion Weighted MRI (DW-MRI) is superior to Multidetector Computed axial Tomography (MDCT) in the detection of colorectal liver metastases. Fatty changes in the liver after chemotherapy treatment likely reduces the chances of seeing metastatic lesions on CT especially when the lesions are small (\<10 mm). When compared with CT, Primovist-enhanced MRI and DW-MRI have the potential to provide higher contrast resolution enabling better detection of colorectal liver metastases following chemotherapy.
2. Primovist-enhanced MRI and DW-MRI are superior to CT in assessing and predicting treatment response of patients with colorectal liver metastases to chemotherapy. Primovist-enhanced MRI by providing superior resolution may provide improved accuracy in metastatic lesion margin detection thereby providing higher accuracy in estimating tumor response based on size criteria. DW-MRI provides information indirectly about tumor composition and therefore is likely to be superior to MD-CT in assessing treatment response.

Two groups of patients will be analyzed. The second group consists of patients with colorectal liver metastases who are to go for chemotherapy prior to surgery for metastases resection. This group will be CT and MRI scanned prior to chemotherapy and after chemotherapy. The first group of patients will consist of those patients who have already received chemotherapy and are likely to have surgery to resect liver metastases. This group will have only one set of scans done 4-6 weeks prior to their operation. The pathology of the resected metastases and CT and MRI images will be analyzed and compared.
