A comparative study between arterial spin labeling and CT perfusion methods on hepatic portal venous flow.
Purpose: The purpose of this study was to evaluate the feasibility and potential usefulness of unenhanced magnetic resonance (MR) hepatic portal perfusion using arterial spin labeling (ASL) among healthy volunteers and hepatocellular carcinoma patients.Materials and Methods: The five healthy volunte...

The regions of interest were placed in both the right and left lobes of the liver or both the right anterior and posterior segments of the liver and were placed over the tumor if a lesion was located within a particular perfusion study slice.Results: In the healthy volunteer study, perfusion rate in hepatic parenchyma showed a peak at the TI2 value of 3,000 ms (254.3 ml/min/100 g ± 58.3). In patients, a fair correlation was observed between CT and MR perfusion (r = 0.795, P < 0.01).Conclusion: Our results demonstrate a significant fair correlation between unenhanced MR hepatic portal perfusion imaging using ASL and CT perfusion during SMA portography. pubtype: Academic Journal doctype: research Journal Article ougenre: Article language: English refInfo: holdings: @attributes: islocal: N |
