“…The high soft tissue contrast resolution in these sequences allows an accurate tumor detection and staging. MRI is the key imaging modality to evaluate liver and biliary tree, also because of the possibility of obtaining cholangiography images [19–23]. The European Society of Gastrointestinal and Abdominal Radiology (ESGAR) Working Group, while providing recommendations on the best use of MRI in the study of liver and biliary tree, suggests the use of DW imaging, perfusion acquisitions, and cholangiopancreatography acquisitions [24].…”

PurposeWe compared diagnostic performance of Magnetic Resonance (MR), Computed Tomography (CT) and Ultrasound (US) with (CEUS) and without contrast medium to identify peribiliary metastasis.MethodsWe identified 35 subjects with histological proven peribiliary metastases who underwent CEUS, CT and MR study. Four radiologists evaluated the presence of peribiliary lesions, using a 4-point confidence scale. Echogenicity, density and T1-Weigthed (T1-W), T2-W and Diffusion Weighted Imaging (DWI) signal intensity as well as the enhancement pattern during contrast studies on CEUS, CT and MR so as hepatobiliary-phase on MRI was assessed.ResultsAll lesions were detected by MR. CT detected 8 lesions, while US/CEUS detected one lesion. According to the site of the lesion, respect to the bile duct and hepatic parenchyma: 19 (54.3%) were periductal, 15 (42.8%) were intra-periductal and 1 (2.8%) was periductal-intrahepatic. According to the confidence scale MRI had the best diagnostic performance to assess the lesion. CT obtained lower diagnostic performance. There was no significant difference in MR signal intensity and contrast enhancement among all metastases (p>0.05). There was no significant difference in CT density and contrast enhancement among all metastases (p>0.05).ConclusionsMRI is the method of choice for biliary tract tumors but it does not allow a correct differential diagnosis among different histological types of metastasis. The presence of biliary tree dilatation without hepatic lesions on CT and US/CEUS study may be an indirect sign of peribiliary metastases and for this reason the patient should be evaluated by MRI.

“…Previous studies have documented overlap in the dynamic contrast enhancement patterns of small mass-forming intrahepatic cholangiocarcinomas (<3 cm) and hepatocellular carcinomas (18,27). In such cases, diffusion weighted imaging performed at a number of different b-values ranging from 0-800 s/mm 2 may help to distinguish ICC from HCC (28,29). Similarly, DW-MRI may assist in distinguishing benign from malignant strictures, which is critical for diagnosis of periductal infiltrating subtypes of ICC (30).…”

Intrahepatic cholangiocarcinomas account for approximately 20% of cases of cholangiocarcinomas.Three growth patterns or morphologic subtypes exist, including mass-forming, periductal-infiltrating, and intraductal-growth subtypes. Knowledge of these morphologic subtypes and their radiologic appearance aids in timely diagnosis, a key to optimizing patient outcomes. The morphologic variability of intrahepatic cholangiocarcinomas has a direct impact on the diagnostic sensitivity and specificity of various diagnostic imaging modalities, including ultrasound (US), computed tomography (CT), magnetic resonance imaging (MRI)/magnetic resonance cholangiopancreatography (MRCP), and positron emission tomography (PET).The following review emphasizes optimal imaging technique for each of these modalities and reviews the imaging appearance of each morphologic subtype of intrahepatic cholangiocarcinoma.

“…Esa característica es el equivalente al típico patrón de realce que muestran los CC formadores de masa visualizados en secuencias dinámicas de RM. 14,15 También se ha descrito que las secuencias de DWI con valores b altos, adicionales a las secuencias dinámicas con inyección de ácido gadoxético (contraste hepatoespecífico) aumentan significativamente la sensibilidad en la detección de la extensión ductal o invasión intrahepática en los tumores perihiliares, en comparación a la caracterización de la lesión únicamente con secuencias dinámicas, lo que es útil en la evaluación de la resecabilidad tumoral. 16…”

ResumenEl colangiocarcinoma (CC) es el segundo tumor primario maligno más frecuente del hígado. La mayor incidencia se registra en Asia y su pronóstico es poco alentador. La resección quirúrgica del tumor es el único tratamiento potencialmente curativo. Sin embargo, la mayoría de los CC se diagnostican en estadios avanzados de la enfermedad y la recurrencia del tumor es común. Este trabajo pretende demostrar las características imagenológicas de los CC, su clasificación, así como también la evaluación preoperatoria por tomografía computada (TC) y resonancia magnética (RM) que el radiólogo debe realizar actualmente.
