“…MRCP may have some potential advantages over CT in identifying intrahepatic mass lesions, and can provide a three-dimensional computerized reconstruction of the biliary tree allowing assessment of bile ducts both above and below a stricture. The non-invasively acquired cholangiographic images obtained by MRCP are comparable with invasive cholangiographies (ERCP and PTC), high positive and negative predictive values for detecting the level and features of biliary obstructions [61,[66][67][68] . Owing to its intrinsically high tissue contrast and multiplanar capability, MRCP is superior to ERCP for defining the anatomy of tumor and assessing its respectability.…”

Intrahepatic cholangiocarcinoma (ICC) is a rare primary liver cancer with a global increasing trend in recent years. Symptoms tend to be vague and insidious in development, often are diagnosed at an advanced stage when only palliative approaches can be used with a median survival rate of months. Comparing with HCC, ICC tends to spread to lymph nodes early, and is rarely limited to the regional lymph nodes, with a frequent postoperative recurrence. Surgery is the only choice of curative therapy for ICC, but recently no consensus has been established for operation. Thus, more data from multiple centers and more cases are needed. Generally speaking, current adjunctive therapy cannot clearly improve survival. Further research is needed to find more effective radio-and chemotherapeutic regimens.

“…However, CT can only establish the resectability in 60% of cases [61] , and cannot usually define the extent of cholangiocar-cinoma because of the sclerosis and fibrosis of surrounding tissue. In addition, CT cannot accurately differentiate ICC from PSC [62] .…”

“…Although computed tomography provides better anatomical detail (e.g., by depicting vascular or extrahepatic invasion) and more accurate staging (118), magnetic resonance imaging allows greater contrast which facilitates detection of the tumor and evaluation of hepatic parenchymal changes peripheral to the tumor. However, the two modalities are equally effective at detecting and correctly diagnosing the tumor (32).…”

Clonorchiasis and Cholangiocarcinoma: Etiologic Relationship and Imaging Diagnosis

et al. 2004

Despite a gradual decrease in prevalence, clonorchiasis is still prevalent in East Asia. A large and compelling body of evidence links clonorchiasis and cholangiocarcinoma, although the mechanisms involved are not completely understood. Clonorchiasis induces biliary epithelial hyperplasia and metaplasia, and this could facilitate at least one stage of the carcinogenesis, which is promoting effect. In areas of endemic infection, more clonorchiasis cases are now diagnosed incidentally during radiological examinations such as cholangiography, ultrasonography, and computed tomography. Radiological findings are regarded as pathognomonic for clonorchiasis since they reflect the unique pathological changes of this disorder. These radiological examinations currently play important roles in the diagnosis, staging, and decision-making process involved in the treatment of cholangiocarcinoma. The morphological features and radiological findings of clonorchiasis-associated cholangiocarcinoma are essentially combinations of the findings for the two diseases. The morphological features of clonorchiasis- associated cholangiocarcinoma, observed in radiological examinations, do not differ from those of the usual cholangiocarcinoma. In patients diagnosed with or suspected to have clonorchiasis, radiological findings should be carefully scrutinized for occult cholangiocarcinoma

Intrahepatic Peripheral Cholangiocarcinoma: Comparison of Dynamic CT and Dynamic MRI

Abstract: Both D-CT and D-MRI can provide important information for the diagnosis of PCC. D-CT is better than D-MRI for demonstrating vascular involvement and extrahepatic invasion. D-MRI gives more conspicuous enhancement.
