Purpose: Dual velocity encoding PC-MRI can produce spurious artifacts when using high ratios of velocity encoding values (VENCs), limiting its ability to generate high-quality images across a wide range of encoding velocities. This study aims to propose and compare dual-VENC correction methods for such artifacts.
Theory And Methods: Two denoising approaches based on spatiotemporal regularization are proposed and compared with a state-of-the-art method based on sign correction.
Background: Surgical management of large ventral hernias (VH) has remained a challenge. Various techniques like anterior component separation and posterior component separation (PCS) with transversus abdominis release (TAR) have been employed. Despite the initial success, the long-term efficacy of TAR is not yet comprehensively studied.

- The study aimed to investigate factors related to lateral lymph node (LLN) involvement in patients with locally advanced rectal cancer (LARC) undergoing neoadjuvant chemoradiotherapy (nCRT) and surgery, focusing on their effect on local recurrence rates.
- The retrospective analysis included 301 LARC patients treated between 2014 and 2019, assessing MRI results for LLN involvement and categorizing patients based on whether they had suspicious nodes.
- Findings revealed that while 15.9% showed suspicious LLNs on initial MRI, abnormal LLNs did not independently affect local recurrence rates after 3 years, suggesting they may not be a significant risk factor in this context.
Purpose: The phase of a MRI signal is used to encode the velocity of blood flow. Phase unwrapping artifacts may appear when aiming to improve the velocity-to-noise ratio (VNR) of the measured velocity field. This study aims to compare various unwrapping algorithms on ground-truth synthetic data generated using computational fluid dynamics (CFD) simulations.

The present study evaluated the effect of age on postoperative outcomes among patients undergoing laparoscopic right colectomies with CME for right-sided colon cancer (RCC).
Methods: Data of patients undergoing laparoscopic right colectomies with CME for RCC between 2015 and 2018 were retrospectively analyzed.
