Image noise (IN), lesion to liver signal to noise (SNR) and contrast to noise (CNR) ratios were quantitatively analysed; image quality was rated on a 5-point scale (1, excellent; 2, good; 3, fair; 4, poor; 5, non-diagnostic) by two independent reviewers.#In 21 patients with hypo...
Computed tomography of the spleen: how to interpret the hypodense lesion BackgroundAs the largest single lymphatic organ in the human body, the spleen is responsible for central immunological and haematological tasks. Therefore,... CA Karlo,P Stolzmann,RK Do,... - 《Insights Into Imaging》 被...

Both, parenchyma- and lesion-mimic were filled with different solutions exhibiting 80/100/120HU and 0/15/40/60HU, respectively. Further, a total of 74 contrast-enhanced studies performed on a spectral detector CT scanner (SDCT) were included in this retrospective study. Patients had MRI or ...
Lesion segmentationHypodense liver lesions are commonly detected in CT, so their segmentation and characterization are essential for diagnosis and treatment. Methods for automatic detection and segmentation of liver lesions were developed to support this task.The detection algorithm uses an object-based ...
liver lesion detectionRationale and Objectives To determine the impact of incremental increases in computed tomography (CT) image noise on detection of low-contrast hypodense liver lesions. Material and Methods We studied 50 CT examinations acquired at image noise index (NI) of 15 and hypodense ...
