Insights

Dynamic snapshot-FLASH MRI effectively visualizes focal nodular hyperplasia (FNH) in the liver. This technique offers high contrast and time resolution, aiding in differentiating hepatic tumors.

Area of Science:

  • Radiology
  • Medical Imaging
  • Hepatology

Context:

  • Focal nodular hyperplasia (FNH) is a common benign liver tumor.
  • Accurate diagnosis of FNH is crucial for appropriate patient management.
  • Distinguishing FNH from other hepatic lesions can be challenging.

Purpose:

  • To evaluate the efficacy of dynamic snapshot-FLASH MRI in characterizing FNH.
  • To compare snapshot-FLASH MRI with conventional MRI sequences for FNH imaging.
  • To assess the diagnostic performance of dynamic snapshot-FLASH MRI for hepatic tumors.

Summary:

  • Eleven FNH lesions in six patients were imaged using dynamic snapshot-FLASH MRI before and after Gd-DTPA contrast administration.
  • Snapshot-FLASH MRI sequences were compared with T1/T2-weighted spin-echo and T1-weighted breathhold-FLASH images.
  • Dynamic snapshot-FLASH MRI demonstrated high lesion-to-liver signal-difference-to-noise ratios and reliably depicted the characteristic hemodynamics of FNH.

Impact:

  • Dynamic snapshot-FLASH MRI provides high contrast and temporal resolution for FNH imaging.
  • This technique may improve the differential diagnosis of hepatic tumors.
  • It offers a valuable tool for non-invasive characterization of liver lesions.

Cirrhosis I: Introduction

Cirrhosis is a chronic, irreversible liver disease characterized by the widespread replacement of healthy liver tissue with fibrotic scar tissue and the formation of regenerative nodules.Etiology of cirrhosisCirrhosis results from sustained liver injury that triggers progressive fibrosis and structural remodeling. The underlying causes are diverse, encompassing common and less frequent clinical conditions. Regardless of the origin, all causes lead to chronic inflammation, hepatocyte loss, and...
