“…Good agreement was observed between findings at angiography and those at gadolinium-enhanced MR imaging for the detection of arterial abnormalities (Fig 3b, 3c) (13,26). Three-dimensional spoiled gradient-echo sequences allow evaluation of the liver parenchyma as well as the hepatic vessels.…”

Complications of Liver Transplantation: Multimodality Imaging Approach

et al. 2007

Liver transplantation is currently an accepted first-line treatment for patients with end-stage acute or chronic liver disease, but postoperative complications may limit the long-term success of transplantation. The most common and most clinically significant complications are arterial and venous thrombosis and stenosis, biliary disorders, fluid collections, neoplasms, and graft rejection. Early diagnosis is crucial to the successful management of all these complications, and imaging plays an important role in the diagnosis of all but graft rejection. A multimodality approach including ultrasonography and cross-sectional imaging studies often is most effective for diagnosis. Each imaging modality has specific strengths and weaknesses, and the diagnostic usefulness of a modality depends mainly on the patient's characteristics, the clinical purpose of the imaging evaluation, and the expertise of imaging professionals.

“…Although Meaney et al 32 and Ernst et al 33 showed that the technique can be used to assess mesenteric arterial circulation, Rodgers et al 34 used the technique to assess the portal venous system. Stafford-Johnson et al 35 showed that 3D MRA is capable of showing vascular complications after liver transplantation.…”

The purpose of this study was to determine the practicability and diagnostic accuracy of a magnetic resonance (MR) protocol capable of replacing computed tomography, catheter angiography, and endoscopic retrograde cholangiopancreatography for the presurgical evaluation of potential liver donors before right hepatectomy. MR imaging (MRI) was performed on a 1.5 T scanner using a phased-array torso surface coil for signal reception. The following image sets were collected: axial two-dimensional (

“…Another more accurate morphological assessment of the portal venous system, such as 3D contrast-enhanced MR portography, 31 is also reported. However, we believe functional quantitative parameters may be more subjective than qualitative morphological assessment.…”

MR-based Measurements of Portal Vein Flow and Liver Stiffness for Predicting Gastroesophageal Varices

et al. 2013

Objectives: We evaluated ‰ow parameters measured by phase-contrast magnetic resonance (MR) imaging (PC-MRI) of the portal venous system and liver stiŠness measured by MR elastography (MRE) to determine the usefulness of these methods in predicting gastroesophageal varices (GEV) in patients with chronic liver disease (CLD).Methods: In patients with CLD and controls, we performed PC-MRI on the portal (PV) and superior mesenteric veins; calculated mean velocity (V, cm/s), cross-sectional area (S, mm 2 ), and ‰ow volume (Q, mL/min); and determined markers of liverˆbrosis (liver stiŠ-ness [kPa]) and aspartate aminotransferase (AST) platelet ratio index [APRI]). We visually assessed GEV and development of collateral pathways of the PV on routine contrast-enhanced dynamic MR imaging and compared patient characteristics, ‰ow parameters, liver stiŠness markers, and visual analysis among 3GEV groups, those with mild, severe, or no GEV with reference to endoscopicˆndings.Results: Child-Pugh grade, V PV , S PV , liver stiŠness, APRI, and visually identiˆed GEV (visible GEV) diŠered signiˆcantly among the 3 groups (Pº0.05). We investigated V PV , S PV , liver stiŠness, and visible GEV as independent markers to distinguish patients with and without GEV and examined V PV and visible GEV to predict severe GEV. Visible GEV showed low sensitivity (14 to 30z) and high speciˆcity (98z) for predicting GEV in patients with CLD. A subgroup analysis that excluded cases with collateral pathway demonstrated slightly improved diagnostic performance of V PV and liver stiŠness.Conclusions: Portal vein ‰ow parameters and liver stiŠness can be useful markers for predicting GEV in patients with CLD.
