Contrast-enhanced computed tomography (CT) plays a crucial role in the diagnosis of hepatic and pancreatic diseases. Generally, multiphasic CT, so-called dynamic CT, is required for the diagnosis of hepatic and pancreatic tumors. The purpose of dynamic CT is to...Ichikawa, Shintaro...
Multiphasic contrast-enhanced multidetector-row CT of liver: contrast-enhancement theory and practical scan protocol with a combination of fixed injection ... The introduction of multidetector-row CT (MDCT) has provided the abdominal radiologists with dramatic changes for the imaging of the liver. At...
Stroszczynski:The case I can describe to you is a patient whose CT scan showed a primary tumor and another lesion. The subsequent MRI scan with a liver-specific contrast agent revealed four additional lesions besides the primary tumor, which had to be resected. ...
Focal Liver Masses: Enhancement Patterns on Contrast-enhanced Images\\u2014Concordance of US Scans with CT Scans and MR Images AIM: The aim of our study was to evaluate the diagnostic value of Contrast-Enhanced Ultrasound (CEUS) for the characterization of focal liver lesions in a ... Burns,...
Due to the low contrast, blurred edges, large variability in shape and complex context with clutter features surrounding the liver that characterize the liver CT images, it is a convoluted problem and still a challenge task to robustly and accurately segment the liver. In this paper, we ...
Objective To evaluated CT contrast enhanced of liver in various bolus. Methods In 132 cdses of lesions of liver, 52 of them were carcinoma, 23 of them were hemangioma of liver, 17 of them were cirrhosis of were hepatic cyst, 16 of them were metastasis cancer of liver, 3 of them were ...
All cases where it was not possible to review the timing and the degree of washout on CEUS (23 cases), or a validated diagnostic reference standard, either CT/MRI scan or histology, was not available (35 cases), were excluded. The algorithm of the study is shown in Figure 1. Open in...
with contrast-enhanced CT.Results After CEUS the number of Ⅲ-Ⅳ grade flow lesions was significantly more than before CEUS(P0.05).The enhancement types of metastatic liver tumors were various,scarcing specificity compared with pathologic cell types of the primary tumors.At arterial phase the ...

An ultrasound, CT, or MRI may show the location and size of the tumor. You may be given contrast liquid to help the tumor and blood vessels show up better. Tell the healthcare provider if you have ever had an allergic reaction to contrast liquid. Do not enter the MRI room with anythin...
