Article Abstract
Background: Hepatocellular carcinoma (HCC) is the fourth most common cause of cancer-related death worldwide. Angiogenic factors may be valuable indices of tumor recurrence and treatment and potentially useful markers for predicting the response to antiangiogenesis therapy. Vascular endothelial growth factor (VEGF) and matrix metalloproteinases (MMPs) are major drivers of tumor angiogenesis. Preoperatively predicting the expression of VEGF and MMPs is crucial for treating HCC. Intravoxel incoherent motion (IVIM) diffusion-weighted imaging (DWI) has been successfully used in the differential diagnosis of HCC, pathological grading, and treatment response evaluation. However, the correlations between IVIM-DWI parameters and VEGF and MMP expression have not been reported. This study provides a preliminary analysis of the correlation between IVIM-DWI parameters and the expression of VEGF, MMP-2, and MMP-9 to investigate the value of IVIM-DWI in the noninvasive evaluation of angiogenesis in HCC.
Methods: IVIM-DWI was performed in 61 patients with HCC 1 week before they underwent surgical resection. VEGF, MMP-2, and MMP-9 expression was detected using immunohistochemistry staining. Spearman correlation analysis was used to analyze the correlations between the IVIM-DWI parameters and VEGF, MMP-2, and MMP-9 expression in HCC.
Results: The fast apparent diffusion coefficient fraction () value was positively correlated with the expression of VEGF (P<0.001), MMP-2 (P=0.002), and MMP-9 (P<0.001). The fast apparent diffusion coefficient (*) was positively correlated with VEGF (P<0.001) and MMP-9 (P<0.001) expression but was not correlated with MMP-2 (P=0.659) expression. The apparent diffusion coefficient (ADC) and slow apparent diffusion coefficient () values were not significantly correlated with the expression of VEGF (P=0.103 and P=0.543, respectively), MMP-2 (P=0.596 and P=0.338, respectively), or MMP-9 (P=0.102 and P=0.660, respectively).
Conclusions: IVIM-DWI can be used to noninvasively evaluate angiogenesis in HCC.

This study aimed to evaluate the diagnostic performance of simplified intravoxel incoherent motion (IVIM) diffusion-weighted imaging (DWI) parameters in distinguishing malignant from benign breast lesions, and to explore their association with clinicopathological features. This retrospective study included 108 women who underwent breast MRI with multi-b-value DWI (0, 20, 200, 500, 800 s/mm). Of those 108 women, 73 had pathologically confirmed malignant lesions.

Background: Renal dysfunction is a common complication in patients with cirrhosis, and early detection is crucial for timely intervention and treatment. Intravoxel incoherent motion (IVIM) diffusion-weighted imaging (DWI) serves as a non-invasive imaging technique that provides valuable insights into tissue perfusion and diffusion changes, demonstrating significant superiority in assessing renal injury. This prospective study aimed to evaluate early renal injury in patients with cirrhosis using IVIM DWI and to explore the correlation of IVIM parameters with the severity of liver cirrhosis based on the Child-Pugh classification.

Purpose: Intravoxel incoherent motion (IVIM) diffusion-weighted imaging (DWI) enhances tissue diffusion assessment by differentiating true molecular diffusion from microvascular perfusion, surpassing conventional DWI. This prospective study assessed the prognostic utility of F-FDG PET/MRI with IVIM imaging in patients with primary nasopharyngeal carcinoma (NPC).
Methods: We prospectively enrolled 148 patients with primary NPC who underwent pretreatment PET/MRI.

This research presents a novel analytical method for breast tumor characterization and tissue classification by leveraging intravoxel incoherent motion diffusion-weighted imaging (IVIM-DWI) combined with hyperspectral imaging techniques and deep learning. Traditionally, dynamic contrast-enhanced MRI (DCE-MRI) is employed for breast tumor diagnosis, but it involves gadolinium-based contrast agents, which carry potential health risks. IVIM imaging extends conventional diffusion-weighted imaging (DWI) by explicitly separating the signal decay into components representing true molecular diffusion (D) and microcirculation of capillary blood (pseudo-diffusion or D*).
