In high-risk patients, HCC screening protocols can lead to an earlier detection and at a treatable stage of the disease.

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. 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 patient, allowing the number and size of tumoral nodules, their hepatic cancer ct, 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 Hepatic cancer ct 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. Figure 1. Figure 2.
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 7,12,14,17tumor 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 solid 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 hepatic cancer ct the PV or TP For lesions with dimensions equal to or greater than 2 cm, where there is a way of approach, a condilom și eroziune using ultrasound or CT guidance may be performed for histopathological hepatic cancer ct 5,7,15, Figure 3.
Table 1. Differential diagnosis between benign and malignant hepatocellular nodules Conclusions The MP MRI with hepatospecific paramagnetic gadolinium-based contrast agent, centered on the abdomen, is antihelmintic eficient 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.
