How Cardiac Fibrosis Assessed via T1 Mapping Is Associated with Liver Fibrosis in Patients with Non-Alcoholic Fatty Liver Disease.

(1) Background: Nonalcoholic fatty liver disease (NAFLD) is one of the most common chronic liver diseases worldwide. Although cardiovascular and NAFLD risk factors overlap, an independent association between these conditions may exist. Hepatic and cardiac fibrosis are important markers of mortality, but the correlation between these markers in patients with NAFLD has not been well studied.

Can gadoxetic acid-enhanced magnetic resonance imaging be used to avoid liver biopsy in patients with nonalcoholic fatty liver disease?

Background: Nonalcoholic fatty liver disease (NAFLD) is a major cause of liver disease worldwide. The diagnosis of nonalcoholic steatohepatitis (NASH), the most severe form of NAFLD, is crucial and has prognostic and therapeutic implications. However, currently this diagnosis is based on liver biopsy and has several limitations.

Fat-containing liver lesions: a pictorial review.

The aim of this pictorial essay is to review the spectrum of fat-containing liver lesions and their characterisation on magnetic resonance imaging with focus on the radiological features that aid in the differential diagnoses. Fat-containing liver lesions comprise a heterogeneous group of tumours with variable imaging findings. Magnetic resonance imaging clearly displays the micro- and macroscopic fat components of the lesions and other characteristic features that are helpful tools to make the differential diagnosis.

Preperitoneal fat as a non-invasive marker of increased risk of severe non-alcoholic fatty liver disease in patients with type 2 diabetes.

Background And Aim: Fat distribution may have prognostic value in the evaluation of non-alcoholic fatty liver disease. This study was conducted to evaluate associations of magnetic resonance imaging-measured abdominal fat areas with steatosis, steatohepatitis, and fibrosis, assessed histopathologically, in patients with type 2 diabetes.

Methods: This prospective study included 66 patients with type 2 diabetes (12 males, 54 females, age 26-68 years), without chronic liver disease of other causes.

Intravoxel Incoherent Motion Diffusion Weighted MR Imaging at 3.0 T: Assessment of Steatohepatitis and Fibrosis Compared with Liver Biopsy in Type 2 Diabetic Patients.

Objective: To evaluate the capability of intravoxel incoherent motion (IVIM) diffusion-weighted imaging (DWI) to assess steatohepatitis and fibrosis determined by histopathology in type 2 diabetic patients.

Methods: Fifty-nine type 2 diabetic patients (49 women, 10 men; mean age, 54 ± 9 years) were submitted to liver biopsy for the evaluation of non-alcoholic fatty liver disease (NAFLD) and underwent DWI on a 3.0T MR system using 10 b values.

Hepatobiliary contrast agents: differential diagnosis of focal hepatic lesions, pitfalls and other indications.

The characterization of focal liver lesions is very important. Magnetic resonance imaging is considered the best imaging method for evaluating such lesions, but does not allow for the diagnosis in all cases. The use of hepatobiliary contrast agents increases the diagnostic accuracy of magnetic resonance imaging and reduces the number of non-specific liver lesions.

Computed tomography and magnetic resonance enterography findings in Crohn's disease: what does the clinician need to know from the radiologist?

The purpose of this pictorial essay was to discuss and illustrate computed tomography and magnetic resonance enterography findings in patients with Crohn's disease. These noninvasive and easily performed methods for the evaluation of Crohn's disease are useful for differentiating between active and fibrotic bowel disease, and can help to guide treatment (medical vs surgical). Although inflammatory and fibrostenotic findings of Crohn's disease may overlap, computed tomography and magnetic resonance enterography can help to identify the presence, extent, and severity of active inflammation that may respond to medical therapy, and the existence of fistulas and fibrostenosis that may benefit from surgical management.

Multiparametric magnetic resonance imaging of the prostate.

The multiparametric approach expanded the clinical applications for prostate magnetic resonance (MR) imaging to include not only staging but also a correlation with tumor aggressiveness. It can also help to guide biopsies, to achieve a higher tumor detection rate, and to better reflect the true Gleason grade. The improved accuracy provided by multiparametric MR imaging and a better understanding of the clinical significance of the imaging findings can pave the way to a more direct role of MR imaging in patient management.
