Virtual portal pressure from anatomic CT angiography

Reply to: "virtual portal pressure from anatomic CT angiography".

To the Editor: We thank Qi et al. [1] for their interest in our study proposing a non-invasive computed tomography (CT)-based model predicting the level of hepatic venous pressure gradient (HVPG): HVPG score = 17.37–4.91 ln(Liver/Spleen ratio) + 3.8 [if presence of peri-hepatic ascites], entitled ‘‘Accurate computed tomographybased portal pressure assessment in patients with hepatocellular carc...

Diagnostic accuracy of fractional flow reserve from anatomic CT angiography.

CONTEXT Coronary computed tomographic (CT) angiography is a noninvasive anatomic test for diagnosis of coronary stenosis that does not determine whether a stenosis causes ischemia. In contrast, fractional flow reserve (FFR) is a physiologic measure of coronary stenosis expressing the amount of coronary flow still attainable despite the presence of a stenosis, but it requires an invasive procedu...

FDG-avid portal vein tumor thrombosis from hepatocellular carcinoma in contrast-enhanced FDG PET/CT

Objective(s): In this study, we aimed to describe the characteristics of portal vein tumor thrombosis (PVTT), complicating hepatocellular carcinoma (HCC) in contrast-enhanced FDG PET/CT scan. Methods: In this retrospective study, 9 HCC patients with FDG-avid PVTT were diagnosed by contrast-enhanced fluorodeoxyglucose positron emission tomography/computed tomography (FDG PET/CT), which is a comb...
