Gadoxetic acid, a hepatobiliary-specific contrast medium used for MRI, is becoming increasingly important in the detection and characterization of hepatic mass lesions. In case of a nodule showing central uptake of contrast agent in the HBP due to fibrotic content, imaging assessment should be based on extracellular phases: If the lesion shows irregular peripheral enhancement in the hepatic arterial phase and gradual centripetal enhancement on following phases, the diagnosis of intrahepatic cholangiocarcinoma is favored because this entity may show central uptake in 4257% of cases [18,19,20]; if the patient has a history of malignancy and a target rim appearance on post-contrast phases, the lesion is suspicious for metastasis although central uptake in the HBP is not a common imaging presentation of liver metastases [22, 23, 67]. Raman SP, Singhi A, Horton KM, Hruban RH, Fishman EK. FNHs show iso- or hyperintensity in the HBP relatively to liver parenchyma in the vast majority (97%) of cases [10] (Fig.2), and this is attributed to OATP1B3 expression equal or higher than that of the background liver or to an increase in well-differentiated bile ducts in these lesions compared to the surrounding parenchyma [29,30,31,32,33]. WMHs are also referred to as Leukoaraiosis and are often found in CT or MRIs of older patients. In our study, only one case presented signal decrease on in-phase. [18, 19] Yoshimura et al.

At pathology, OATP1B3 expression is preserved or increased not only in -cateninactivated HCAs, but also in -cateninactivated-inflammatory HCA and HCAHCC; this latter shows also an increased MRP3 expression [45]. https://doi.org/10.1186/s12880-023-01008-3, DOI: https://doi.org/10.1186/s12880-023-01008-3. For instance, An et al. This typical iso- or hyperintensity of FNH relatively to liver parenchyma in the HBP allows the differential diagnosis between FNH and HCAwhich is hypointense relatively to liver parenchyma most of the timewith a specificity of 91100% [10, 11, 34] and a superior accuracy compared to other morphological and dynamic vascular criteria alone and in combination [35]; in clinical practice, its presence decreases the number of indeterminate or inconclusive cases that require biopsy or surgery. It indicates the lesions, their volume, and their frequency. The study is approved by Zhongshan Hospital of Fudan University institutional review board. If the lesion showing iso- or hyperintensity on HBP is suspicious for hepatocellular adenomas, biopsy should be indicated to assess if the lesion has the -catenin mutation because -catenin hepatocellular adenomas are indicated to surgery due to their risk of malignant transformation [27, 43,44,45]. The 14 SANT patients (7 men, 7 women; mean age, 43.5 years; age range, 2456 years) presented with a single lesion and showed no specific clinical symptoms.

This pictorial essay reviews a broad spectrum of benign and malignant focal hepatic observations that may show hyperintense signal intensity on HBP on MRI in non-cirrhotic patients, in patients with vascular disorders, in oncologic and cirrhotic patients. HCAs warrant close follow-up and surgery in selected cases considering the possibility of progressive disease [42] and complications (i.e., bleeding) for those exceeding 5cm in diameter despite treatment and, therefore, suspected of malignant transformation [27].

An MRI scan is one of the most refined imaging processes. As discussed above, oncologic patients may show FNH-like nodules after chemotherapy, and the diagnosis of these lesions benefits from the use of hepatobiliary contrast agents. T2-weighted images(1E) and DWI(1 F) show a hypointensity lesion with more hypointense scars in the center. On the ADC map, only one case (8.3%) showed hypointensity, other 11 cases (91.7%) showed hyperintensity or isointensity. It is also linked with constant and resistant depression. For example, when MRI hyperintensity is 2.5 to 3 times, it indicates major depressive disorder or bipolar disorder. In oncologic patients, metastases and cholangiocarcinoma are hypointense lesions in the hepatobiliary phase; however, occasionally they may show a diffuse, central and inhomogeneous hepatobiliary paradoxical uptake with peripheral rim hypointensity.

For PET-CT, the maximum standardized uptake value (SUV) of the lesion during the early and delayed phases was measured. 2010;16(13):156776. The great variability of these percentages in the literature may be partially attributed to the subjective identification of different patterns of FNHs in the various studies.

On T1 weighted imaging, 10 cases (83.3%) were isointense and 2 cases (16.7%) were slightly hypointense. Overall, the MRI scans are highly beneficial in detecting health disorders, allowing proactive designing of the treatment plans. Symmetrical cerebral T2 hyperintensities. Periventricular white matter hyperintensities, Suppose you are having a medical issue, and your physician recommends an MRI. Some SANTs showed hyperintense at the periphery with hypointensity at the center, and have hypointense radiation bands, corresponding to a central stellate fibrous stroma with fibrous septa.[5]. Therefore, its important to know the characteristic imaging finding to distinguish it from other splenic tumors. Chen, NX., Wang, ML., Wang, HX. Liver metastases are broadly classified as hypoenhancing and hyperenhancing relative to the liver parenchyma on hepatic arterial phase. The hypointensity observed on T2-weighted MRI The lesion shows heterogeneous enhancement on arterial phase(1 C) and portal phase(1D). Finally, seven men and seven women were included in our study with an average age of 43.5 (rang from 24 to 56). When the lesion is deemed indeterminate in studies with extracellular agents, the adoption of hepatobiliary MRI contrast agents is particularly relevant for the differential diagnosis between FNH and hepatocellular adenoma in the non-cirrhotic liver [11, 34,35,36] and between FNH-like nodules and HCC or metastases in vascular liver diseases and oncologic patients, respectively [22, 23, 53, 57,58,59, 67, 68].
