Hepatic cancer imaging
In high-risk patients, HCC screening protocols can hepatic cancer imaging 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 hepatic cancer imaging 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 hepatic cancer imaging are other factors that may be associated with HCC hepatic cancer imaging. 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 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 hepatic cancer imaging performed — 20 minutes after the i.

Figure 2. Other auxiliary hepatic cancer imaging 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, hepatic cancer imaging 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 papiloma laringeo 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 benign 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 hepatic cancer imaging hepatic nodule sof its complications portal thrombosis; metastasis-lymph hepatic cancer imaging, pulmonary, bone disseminationanatomical hepatic cancer imaging, and other extrahepatic lesions discovered incidentally.

This study was effectuated on a total of 56 patients with liver cirrhosis and HCC, which are waiting on the transplant list. According to imaging appearance, compared with imaging study before treatment, the results were interpreted as such: tumor regression, identical size hepatic cancer imaging tumor progression.

Ultrasound abdominal transparietal and intraoperativemultidetector computed tomography CT and MRI are the methods of choice to achieve these objectives. For each method, specific intravascular contrast media injection improves the accuracy. The latest method, PET- CT, is used to identify metabolic active tumoral tissue, hepatic cancer imaging for recurrence diagnosis and for guiding biopsies and local treatments.
