Article Synopsis
- The study aimed to compare the effectiveness of intravoxel incoherent motion (IVIM) imaging and arterial spin labeling (ASL) in evaluating renal blood flow in rodent models of acute kidney injury (AKI).
- Researchers tested three fitting methods on diffusion-weighted imaging data to assess the reliability of pseudo-diffusion parameters and their ability to correlate with renal blood flow.
- Findings revealed that while ASL effectively detected a significant drop in renal blood flow due to AKI, IVIM's pseudo-diffusion parameters were not reliable or correlated, suggesting the need for careful consideration when interpreting results using IVIM in kidney studies.
Purpose: Liver resection is currently considered the most effective treatment for patients with liver cancer. To the best of our knowledge, no study has investigated the association between gadoxetic acid-enhanced magnetic resonance imaging (MRI) findings and liver regeneration in patients who underwent hemihepatectomy. We aimed to clarify the relationship between the signal intensity (SI) of the liver parenchyma on gadoxetic acid-enhanced MRI and the degree of liver regeneration in patients who underwent hemihepatectomy.

Methods: In this retrospective single-center study, patients who underwent liver resection or transplantation of HCC were evaluated. Data obtained in patients who underwent liver resection were used as the training set.

Introduction: The purpose is to clarify the safety and clinical contribution of computed tomography (CT)-guided percutaneous needle-biopsy for patients with cervical spine lesion.
Material And Methods: Between June 2015 and August 2022, CT-guided percutaneous needle biopsies were performed for 15 cervical spine lesions of 15 patients (8 male, 7 female; 2-81 years old). The technical success, clinical contribution, and safety were evaluated.
