A magnetic resonance imaging radiomics approach predicts hepatocellular carcinoma response to stereotactic body radiation therapy.

Background And Purpose: Predicting hepatocellular carcinoma (HCC) response to Stereotactic Body Radiation Therapy (SBRT) can be challenging. Here, we assessed the value of a radiomics-based machine learning (ML) approach for predicting HCC response to SBRT, using pre-treatment and early post-treatment magnetic resonance imaging (MRI).

Materials And Methods: This retrospective single-center study included 87 patients (M 67, mean age 65.

Splanchnic hemodynamic parameters measured with 4D flow MRI can diagnose severe portal hypertension.

Objectives: To assess the diagnostic performance of splanchnic hemodynamic parameters measured with 4D flow MRI for diagnosis of severe portal hypertension (PH; hepatic venous pressure gradient (HVPG) ≥ 12 mmHg), and prediction of liver decompensation in patients with chronic liver disease.

Materials And Methods: Our single-center prospective study (2018-2022) enrolled patients undergoing transjugular liver biopsy with wedge HVPG measurement for abdominal 4D flow MRI (MRI-HVPG interval = 28 ± 18 (1-78) days). 4D flow MRI was acquired at 1.

Comparison of MRI, [18F]FDG-PET/CT, and [18F]FDG-PET/MRI for Initial Staging of Multiple Myeloma: A Systematic Review and Meta-analysis.

Purpose: This systematic review and meta-analysis compared the diagnostic performance of MRI, [18F]FDG-PET/CT, and [18F]FDG-PET/MRI in detecting focal bone lesions and bone marrow infiltration in the initial staging of patients with multiple myeloma (MM) who underwent both MRI and [18F]FDG-PET/CT or [18F]FDG-PET/MRI studies.

Patients And Methods: A systematic literature search was conducted across PubMed, Embase, and Cochrane databases, including studies comparing the performance of MRI (WB-MRI or spine/pelvis MRI), [18F]FDG-PET/CT, and/or [18F]FDG-PET/MRI in the same patients for MM initial staging. Pooled sensitivities and concordance between imaging modalities were analyzed using R (package META-R).

Comparative benchmarking of the DeepSeek large language model on medical tasks and clinical reasoning.

DeepSeek is a newly introduced large language model (LLM) designed for enhanced reasoning, but its medical-domain capabilities have not yet been evaluated. Here we assessed the capabilities of three LLMs- DeepSeek-R1, ChatGPT-o1 and Llama 3.1-405B-in performing four different medical tasks: answering questions from the United States Medical Licensing Examination (USMLE), interpreting and reasoning on the basis of text-based diagnostic and management cases, providing tumor classification according to RECIST 1.

Deep Learning-Enabled Automated Quality Control for Liver MR Elastography: Initial Results.

Background: Several factors can impair image quality and reliability of liver magnetic resonance elastography (MRE), such as inadequate driver positioning, insufficient wave propagation and patient-related factors.

Purpose: To report initial results on automatic classification of liver MRE image quality using various deep learning (DL) architectures.

Study Type: Retrospective, single center, IRB-approved human study.

Lemann Index for assessing bowel damage in Crohn's disease: a real world study.

Background & Aims: The Lemann Index (LI), an endpoint to measure cumulative structural bowel damage in Crohn's disease (CD), has been recently updated and validated. We applied this to investigate predictors of bowel damage in a real-world cohort.

Methods: We performed a retrospective study (2008-2022) involving two tertiary referral IBD centers in the US.

MR Enterography in Ulcerative Colitis: Beyond Endoscopy.

Ulcerative colitis (UC) is a chronic idiopathic inflammatory bowel disease (IBD) that progressively affects mucosa and submuccosa of the colon and rectum in a continual pattern. In comparison, Crohn disease (CD), the other type of IBD, is a chronic transmural inflammatory disorder that can involve any part of the gastrointestinal tract. MR enterography (MRE) has emerged as an important imaging modality for the diagnosis and detection of disease activity and complications in CD, with comparable results to those of endoscopy.

Abbreviated MRI Protocols in the Abdomen and Pelvis.

Abbreviated MRI (AMRI) protocols rely on the acquisition of a limited number of sequences tailored to a specific question. The main objective of AMRI protocols is to reduce exam duration and costs, while maintaining an acceptable diagnostic performance. AMRI is of increasing interest in the radiology community; however, challenges limiting clinical adoption remain.

Celiacomesenteric trunk associated with superior mesenteric artery aneurysm: A case report and review of literature.

In rare cases, the celiac artery and the superior mesenteric artery arise from a common origin known as a common celiacomesenteric trunk. Celiac trunk stenosis or occlusion has been reported to accompany this anatomical aberrancy. Even rarer, are aneurysms associated with this common celiacomesenteric trunk.

Gas-Forming Liver Abscess versus Emphysematous Hepatitis: A Radiologic Diagnostic Dilemma-A Case Report and Review of the Literature.

A 38-year-old diabetic woman, with history of cholecystectomy and ventral hernia repair, was hospitalized due to sudden-onset abdominal pain and fever. Computed tomography revealed a mixed collection containing necrotic debris and emphysematous change in the left lobe of the liver mainly in segments II and III. These radiological findings suggested emphysematous hepatitis (EH).
