Detection of Liver Lesions: CT-Arterial Portogrophy vs Contrast-Enhanced CT and MRIMy first experiences with computed angioportography or computed angio-tomography (CTA or CTAP ) of the liver began about sixteen years ago at M.D. Anderson. At the time of its introduction it was a technique...
MR additionally allows 'functional' evaluation such as with DWI, which provides an alternate contrast mechanism that can be used as a whole-body screening technique to search even for lesions o10 mm (Nasu et al, 2006; Padhani et al, 2011). In our study, we compared PET-CT with same-...

Intact liver lobes in mice from different time points after BDL were imaged by phase-contrast CT with a pixel size of 3.25 µm (Fig.1a). The CT slices clearly revealed the bile infarcts and vessels in the livers, and the smallest distinguishable infarct was approximately 10 µm in...
JAMA Insights September 25, 2018 This Clinical Update explains the uses and interpretation of fractional flow reserve (FFR) measures that quantify the pressure gradient proximal and distal to intracoronary lesions and determine the clinical significance of angiographically detected coronary artery stenoses....
However, 96% of hospitals can perform an emergency CT with contrast [17], and so likely have the ability to detect a proximal artery occlusion. Imaging Standard imaging at our center for suspected acute ischemic stroke includes CTA and MRI. CT images were acquired according to standard ...
Accuracy of preoper-ative prediction of microinvasion of portal vein in hepatocellular carcinoma using superparamagnetic iron oxide-enhanced magnetic resonance imaging and computed tomography during hepatic angio-graphy. J Gastroenterol, 2006, 41(10):987-995. 29. Nishie A, Yoshimitsu K, Asayama Y...
The use of hepatobiliary contrast agents introduces additional challenges including arterial phase degradation and suboptimal uptake in advanced cirrhosis. This review provides radiologists with comprehensive insights into the technical aspects of liver imaging for LI-RADS. We discuss common pitfalls ...
To retrospectively assess the accuracy of intravenous (IV) contrast-enhanced multidetector CT (MDCT) in choledocholithiasis detectability, in the presence and absence of positive intraduodenal contrast. Over a 3-year period, patients in whom endoscopic retrograde cholangiopancreatography (ERCP) was perf...
