In this retrospective HIPAA–compliant study (January 2016 through May 2023), patients with biopsy-proven pancreatic adenocarcinoma and a biopsied indeterminate liver lesion underwent a DECT abdominal CT scan. Spectral HU curves were provided for each hypodense liver lesion, and slopes were calculated....
Hypodense liver lesions can be obscured by steatotic liver parenchyma in CT. Low kV p -CT shows no advantage in detecting hypodense lesions in steatotic livers. Additional DECT image information does not improve visualization of hypodense lesions in steatosis. 120 kV p -equivalent imaging yields...

Liver lesionsVirtual monoenergetic images3D-printingObjectives: The well-known boost of iodine associated-attenuation in low-keV virtual monoenergetic images (VMI_low) is frequently used to improve visualization of lesions and structures taking up contrast media. This study aimed to evaluate this concept...
To evaluate dual-energy CT (DECT) imaging of hypodense liver lesions in patients with hepatic steatosis, having a high incidence in the general population and among cancer patients receiving chemotherapy.Nattenmueller, JohannaHosch, WaldemarTri-Thien NguyenSkornitzke, StephanJoeres, AndreasGrenacher,...
Rationale 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 liver lesions and 50 ...
Objective The aim of the study was to establish the reference window settings for display of virtual monoenergetic images (VMIs) from spectral detector computed tomography when assessing hypodense liver lesions.Hokamp, Nils GrosseObmann, Verena C.Kessner, RivkaGilkeson, Robert C.Gupta, AmitPersi...
