Article Synopsis
- The study aimed to analyze noninvasive imaging techniques, specifically arterial spin-labeling (ASL) and blood oxygen level-dependent (BOLD) imaging, for assessing kidney blood flow and oxygen levels in rats experiencing contrast-induced acute kidney injury (CIAKI).
- Thirteen rats were divided into two groups and underwent ASL and BOLD imaging at various time points before and after receiving a contrast agent to monitor changes in renal blood flow (RBF) and oxygenation.
- Results showed that RBF significantly decreased in specific kidney regions after exposure to the contrast agent, with some recovery observed later, highlighting that ASL and BOLD imaging can effectively track renal function changes in CIAKI.
Purpose: To determine the correlation between intravoxel incoherent motion (IVIM) and dynamic contrast-enhanced (DCE) magnetic resonance imaging (MRI) parameters.
Methods: Thirty-eight newly diagnosed NPC patients were prospectively enrolled. Diffusion-weighted images (DWI) at 13 b-values were acquired using a 3.

Article Synopsis
- The study aimed to evaluate the effectiveness of MRI in assessing features of tongue carcinoma and its role in the preoperative staging of the disease.
- MRI showed high sensitivity rates for identifying the tumor stages according to the TNM and AJCC systems, particularly excelling in tumor invasion depth but struggled with lymph nodes smaller than 1 cm.
- Overall, MRI is a helpful tool for preoperative staging, providing valuable information that, when combined with clinical signs, enhances the accuracy of assessing tongue carcinoma.
