Intraluminal magnetic resonance imaging (MRI) is a promising option to guide interventions, offering several advantages over other imaging modalities. It provides high spatial and contrast resolution for imaging luminal structures, excellent extra-luminal soft tissue visualization, real-time tracking of interventional devices, and operates without ionizing radiation. The applications of intraluminal MRI range from high-resolution imaging of vessel walls to MRI-guided interventions for managing life-threatening conditions such as cardiovascular atherosclerotic disease and malignancies within luminal structures.

Background: Timely administration of intravenous recombinant tissue plasminogen activator (rtPA) significantly improves outcomes in acute ischemic stroke (AIS). However, substantial variability in door-to-needle (DTN) time persists in real-world settings. This study aimed to deconstruct DTN time into distinct workflow intervals to identify key determinants of delay and inform targeted quality improvement.

Purpose: Radiotherapy-induced dysphagia can significantly impair head and neck (H&N) cancer patients' quality of life. Despite the dose-dependent relationship between radiotherapy and dysphagia, swallowing structures are not routinely contoured due to time and labor demands. We evaluated atlas-based autosegmentation (ABAS) on MRI, identifying the optimal number of atlases required to efficiently and accurately delineate swallowing structures.

Introduction: This study aimed to evaluate the surgical outcomes of patients undergoing magnetic resonance imaging-guided bracketing (MRI-B) prior to breast-conserving therapy (BCT).
Materials And Methods: This retrospective study included consecutive patients treated with BCT at our institution for invasive or in situ breast cancer between January 2016 and December 2022 and requiring MRI-B before surgery. Bracketing was performed by either inserting MRI-compatible wires or deploying clips under MRI guidance, with subsequent localization using mammography.

Purpose: Magnetic resonance imaging (MRI) to visualize anatomical motion is becoming increasingly important when treating cancer patients with radiotherapy. Hybrid MRI-linear accelerator (MRI-linac) systems allow real-time motion management during irradiation. This paper presents a multi-institutional real-time MRI time series dataset from different MRI-linac vendors.
