This study develops a simple hollow ZrO nanostructure as a carrier to encapsulate ionic liquid (IL), which integrates the CT imaging function of the ZrO shell and the microwave susceptibility function of the IL core. The simple nanostructure can be used as a multifunctional theranostic agent combining diagnostic and therapeutic modalities into one "package". Based on the microwave susceptibility properties, the tumor inhibiting ratio can be over 90% in mice models after one-time thermal therapy upon microwave irradiation. and imaging results prove the potential of CT imaging application for real-time monitoring of biodistribution and metabolic processes, and assessing therapeutic outcomes. To our best knowledge, our study is the first example to achieve CT imaging and microwave thermal therapy simultaneously through a simple nanostructure. We anticipate that the simple IL@ZrO nanostructure may build a useful platform for the clinical imaging guided therapy of tumors.

Ultrasound localization microscopy (ULM) enables microvascular imaging at spatial resolutions beyond the acoustic diffraction limit, offering significant clinical potentials. However, ULM performance relies heavily on microbubble (MB) signal sparsity, the number of detected MBs, and signal-to-noise ratio (SNR), all of which vary in clinical scenarios involving bolus MB injections. These sources of variations underscore the need to optimize MB dosage, data acquisition timing, and imaging settings in order to standardize and optimize ULM of microvasculature.

CT-guided adaptive radiotherapy (ART) for the treatment of pancreatic adenocarcinoma is rapidly increasing and has been shown to provide advanced treatment tools comparable to magnetic resonance imaging (MRI)-guided adaptive therapy. Here, we provide the first case report of a local pancreatic recurrence treatment after definitive resection using cone beam computed tomography (CBCT)-guided ART (CT-guided ART) enabled by HyperSight imaging (Varian Medical Systems, Inc., Palo Alto, CA, USA) for daily delineation of organs-at-risk (OARs) and target to improve the quality of online ART.

Existing image fusion methods primarily focus on complex network structure designs while neglecting the limitations of simple fusion strategies in complex scenarios. To address this issue, this study proposes a new method for infrared and visible image fusion based on a multimodal large language model. The method proposed in this paper fully considers the high demand for semantic information in enhancing image quality as well as the fusion strategies in complex scenes.

Background: Predicting dementia early has major implications for clinical management and patient outcomes. Yet, we still lack sensitive tools for stratifying patients early, resulting in patients being undiagnosed or wrongly diagnosed. Despite rapid expansion in machine learning models for dementia prediction, limited model interpretability and generalizability impede translation to the clinic.

Background: Fetal midgut volvulus is a rare disease, with a high risk of potentially life-threatening fetal complications.
Purpose: The aim of this study was to retrospectively analyze the imaging findings of fetal midgut volvulus diagnosed by magnetic resonance imaging (MRI) and explore its value in non-invasive prenatal diagnosis.
Methods: A retrospective collection of data from 156 fetuses suspected of intestinal obstruction by ultrasound examination in our hospital was conducted.
