In high-risk patients, HCC screening protocols can lead to an earlier detection and at a treatable stage of the disease.
The essential of multiparametric magnetic resonance imaging in hepatocellular carcinoma diagnosis
Keywords Multiparametric Magnetic Resonance Imaging, diagnosis, hepatocellular carcinoma Rezumat Carcinomul hepatocelular CHC este cea mai frecventă tumoră malignă primară a ficatului, asociată frecvent cu ciroza, cu o incidenţă crescândă la nivel mondial.
Protocoalele de screening al CHC la pacienţii cu risc crescut pot duce la detectarea mai precoce şi într-un stadiu tratabil al bolii.
- In particular, attention is given to the information achieved by experimental models, such as phantoms and animal studies.

Patients with haemochromatosis are at increased risk for HCC; obesity and diabetes associated with non-alcoholic steatohepatitis are other factors that may be associated with HCC 1. Imaging, in particular Multiparametric Magnetic Resonance Imaging MP MRI represents a key element in the diagnostic algorithm and in the multidisciplinary customized management of each liver cancer hepatic vein, allowing the number and size of tumoral nodules, their semiology, the involvement of intra- and extrahepatic vascular structures portal venous structures — PV, hepatic veins — HV, inferior vena cava — IVCthe presence extrahepatic spread, the existence of anatomical variants or other incidentally discovered lesions In the waiting time frame, until the hepatobiliary phase HBP is performed — 20 minutes after the i.
The hepatobiliary phase performed about 20 minutes after the i.

Other auxiliary criteria in favour of HCC are: identification of a non-enhancing capsule or pseudo-capsule in the periphery of nodules larger than 3 cm, visibility of the nodule on T2, T2 GRE and DWI wi, respectively hypointense round-oval lesion, on the ADC map liver cancer hepatic vein nodules with dimensions of more than 3 cm, having a mosaic-like pattern structure given by the presence of necrotic, haemorrhagic components, rarely lipomatous or intrinsic calcifications, which alternate with liver cancer hepatic vein areas In the hepatobiliary phase, the vast majority of HCC nodules are T1 hypointense 7,8,14due to the anaplasia and the hepatocyte dysfunction into the tumor Figure 2.
Tumoral thrombosis presents an identical semiology to the hepatic tumor on unenhanced and enhanced MRI of the liver evaluationcharacteristic being the wash-in in AP and the wash-out in the PV or TP For lesions with dimensions equal to or greater than 2 cm, where there is a way of approach, a biopsy using ultrasound or CT guidance may be performed for histopathological framing 5,7,15, Figure 3.

Differential diagnosis between liver cancer hepatic vein and malignant hepatocellular nodules Conclusions The MP MRI with hepatospecific paramagnetic gadolinium-based contrast agent, centered on the abdomen, is the imaging modality of choice to evaluate liver cirrhotic nodules. The imaging report should contain a complete description of the hepatic nodule sof its complications portal thrombosis; metastasis-lymph nodes, pulmonary, bone disseminationanatomical variants, and other extrahepatic lesions discovered incidentally.

This brand new edition Diseases of the Liver and Biliary System, now named Sherlock's Diseases of the Liver and Biliary System, after the late Professor Dame Sheila Sherlock, provides concise, didactic clinical guidance from the leading experts in the field. This new edition is now authored by the leading international name in the subject, and is entirley revised and updated, offering over 2, new references and with emphasis on evidence-based guidance throughout the chapters. The clear chapter structure provides uniformity throughout liver cancer hepatic vein book, and includes summary boxes and key learning points throughout.
