Infantile hepatic hemangioendothelioma (IHH) is the most common vascular tumor of the liver in infancy. Adult with IHH is extremely rare. We presented a diffuse IHH in an adult patient with computed tomography (CT) and magnetic resonance image (MRI) findings.A 39-year-old man was admitted to our hospital because of a 2-year history of abnormal liver function tests and a 7-day history of jaundic...

conclusions atypical irregular tumors should be considered as sos when the patient has received oxaliplatin-based chemotherapy. a qualitative imaging modality diagnosis, such as with diffusion-weighted mri, is superior to a morphological diagnosis in focal sos. this imaging modality can prevent unnecessary operations. case presentation a 40-year-old woman with rectal cancer underwent high anter...

Liver dynamic contrast enhanced (DCE) MRI pharmacokinetic modelling could be useful in the assessment of diffuse liver disease and focal liver lesions, but is compromised by errors in arterial input function (AIF) sampling. In this study, we apply cardiac output correction to arterial input functions (AIFs) for liver DCE MRI and investigate the effect on dual-input single compartment hepatic pe...

Understanding the important alterations during hepatocarcinogenesis as well as the characteristic magnetic resonance imaging (MRI) and histopathological features will be helpful for managing patients with chronic liver disease and hepatocellular carcinoma. Recent advances in MRI techniques, such as fat/iron quantification, diffusion-weighted images, and gadoxetic acid-enhanced MRI, have greatly...

PurposeTo evaluate potential confounding factors in the quantitative assessment of liver fibrosis and cirrhosis using T1 relaxation times.MethodsThe study population is based on a radiology-information-system database search for abdominal MRI performed from July 2018 to April 2019 at our institution. After applying exclusion criteria 200 (59 ± 16 yrs) remaining patients were retrospectively inc...

As a deep learning network with an encoder-decoder architecture, UNet and its series of improved versions have been widely used in medical image segmentation great applications. However, when to segment targets 3D images such as magnetic resonance imaging (MRI), computed tomography (CT), these models do not model the relevance vertical space, resulting poor accurate analysis consecutive slices ...

OBJECTIVE This study determined the effects of insulin versus liraglutide therapy on liver fat in patients with type 2 diabetes inadequately controlled with oral agents therapy, including metformin. RESEARCH DESIGN AND METHODS Thirty-five patients with type 2 diabetes inadequately controlled on metformin monotherapy or in combination with other oral antidiabetic medications were randomized to...

With integrated whole-body PET/MRI, a novel metabolic-anatomic imaging technique recently has been introduced into clinical practice. This review addresses PET/MRI of bone tumors, soft-tissue sarcoma, melanoma, and lymphoma. If PET/MRI literature is not yet available for some types of tumors, potential indications are based on available PET/CT and MRI data. PET/MRI seems to be of benefit in T-s...

Purpose We introduce a novel, generalized tracer kinetic model selection framework to quantify microvascular characteristics of liver and tumor tissue in gadoxetate-enhanced dynamic contrast-enhanced MRI (DCE-MRI). Methods Our includes hierarchy nested models, from which physiological parameters are derived 2 regimes, corresponding the active transport free diffusion gadoxetate. use simulations...

Abstract Hepatocellular carcinoma (HCC) may have an infiltrative appearance in about 8–20% of cases. Infiltrative HCC can be a challenging diagnosis and it is associated with the worst overall survival among patients. characterized by spread multiple minute nodules throughout liver, without dominant one, ultimately resulting into macrovascular invasion. On CT MRI, appears as ill-define...
