Computed tomography of liver infarction

CT of focal hepatic injury due to surgical retractor.

“…Infancts have low attenuation on unenhanced scans and usually do not enhance on contrast scans [4]. lnfarcts change oven time, decreasing in size, and cause atrophy of the affected lobe.…”

Liver allograft transplantation: postoperative CT findings

“…The size of these foci is not characteristic of the larger peripheral regions of low attenuation that have been described with liver infarction [8]. Small parenchyrnal defects were also seen in the setting of infection (diffuse and focal) and rejection.…”

Hepatic Infarction Complicated with Acute Pancreatitis Precisely Diagnosed with Gadoxetate Disodium-enhanced Magnetic Resonance Imaging

“…Clinicians can thus evaluate hepatocellular function by contrast enhancement in gadoxetate disodium-enhanced MR imaging in the hepatobiliary phase. Conventional CT has been typically employed for diagnosing hepatic infarction (10,12,13). However, the area that contained both the hepatic perfusion defect and hepatocyte dysfunction (4.3 mL in gadoxetate disodium-enhanced MR imaging in the hepatobiliary phase), which represented the definitive infarction region in this case, was smaller than the perfusion reduction seen in the early period of disease onset (35.6 mL on contrast-enhanced CT in the early phase), suggesting that CT-based perfusion diagnosis alone may risk overestimating the infarction size and unnecessary treatment.…”

“…Conventional computed tomography (CT) is generally considered the most useful modality for diagnosing this condition despite few published large case series (10,12,13). However, hepatic infarction is best evaluated from two perspectives: hepatic hemodynamics and hepatocellular function.…”
