Spatiotemporal monitoring of tissue coagulation treated by continuous high-intensity focused ultrasound with pulse-inversion shear wave elastography.

High-intensity focused ultrasound (HIFU) is a widely used non-invasive modality for tissue ablation. Ultrasound-based monitoring of HIFU therapy is essential but remains challenging due to strong acoustic interference during treatment. This study investigates the integration of pulse inversion (PI) imaging to suppress HIFU-induced artifacts and improve the accuracy of shear wave elastography (SWE) for monitoring tissue thermal responses during treatment.

Confidence-enhanced flow trajectory imaging using speckle tracking with multi-angle plane waves.

Flow trajectory imaging, which tracks flow particles over time to map path-dependent trajectories, is a valuable tool for analyzing flow dynamics in pathological vascular conditions. Accurate trajectory estimation depends on robust vector flow imaging (VFI) methods to minimize cumulative errors. However, Doppler-based VFI methods are limited by aliasing and ensemble-sensitive estimation errors, while speckle tracking (ST) methods suffer from poor lateral velocity estimation due to beam diffraction.

Magnetic Resonance Enterography of Phlebosclerotic Colitis: A Case Report.

Background: Phlebosclerotic colitis is a rare type of chronic ischemic colitis, with most documented cases occurring in Asians. Plain-film and computed tomography findings of pericolonic vascular calcifications are diagnostic. However, Magnetic Resonance Enterography (MRE) findings of phlebosclerotic colitis have not yet been reported, and its diagnosis might be overlooked without awareness of this disease.

Fluorescence-guided thoracoscopic surgery for postoperative chylothorax: A technical note with video vignette.

Technique: The surgical management for high-output postoperative chylothorax typically necessitates ligation of the thoracic duct (TD) above the leak site and/or sealing the leak with a clip. However, pinpointing these structures during subsequent surgeries can be challenging due to their variable course and the presence of traumatized tissues surrounding the leak area. In response to this, we have developed a novel, fluorescence-guided technique that significantly enhances intraoperative identification of the leak point and the TD.

Personalized neoantigen-based T cell therapy triggers cytotoxic lymphocytes expressing polyclonal TCR against metastatic ovarian cancer.

Neoantigen-reactive cytotoxic T lymphocytes play a vital role in precise cancer cell elimination. In this study, we demonstrate the effectiveness of personalized neoantigen-based T cell therapy in inducing tumor regression in two patients suffering from heavily-burdened metastatic ovarian cancer. Our approach involved the development of a robust pipeline for ex vivo expansion of neoantigen-reactive T lymphocytes.

Vascular responses of penetrating vessels during cortical spreading depolarization with ultrasound dynamic ultrafast Doppler imaging.

The dynamic vascular responses during cortical spreading depolarization (CSD) are causally related to pathophysiological consequences in numerous neurovascular conditions, including ischemia, traumatic brain injury, cerebral hemorrhage, and migraine. Monitoring of the hemodynamic responses of cerebral penetrating vessels during CSD is motivated to understand the mechanism of CSD and related neurological disorders. Six SD rats were used, and craniotomy surgery was performed before imaging.

Clinical outcomes of AngioJet rheolytic thrombectomy in the treatment of May-Thurner syndrome-related deep venous thrombosis.

Objective: May-Thurner syndrome (MTS) is an anatomic stenotic variation associated with deep vein thrombosis (DVT) of the left leg. The classical DVT treatment strategy is medical treatment without thrombus removal. This study was performed to assess the clinical outcomes of the combination of AngioJet™ rheolytic thrombectomy and stenting for treatment of MTS-related DVT.

Hypersensitivity Reactions to Iodinated Contrast Media.

At present, iodinated contrast media (ICM) are mostly non-ionic, have low osmolality, and are safe. Even if adverse drug reactions (ADRs) occur, most are chemo-toxic symptoms and require only observation or H1 antihistamines. However, rare, unpredictable, and even life-threatening hypersensitivity can still occur.

Quantitative imaging of ultrasound backscattered signals with information entropy for bone microstructure characterization.

Osteoporosis is a critical problem during aging. Ultrasound signals backscattered from bone contain information associated with microstructures. This study proposed using entropy imaging to collect the information in bone microstructures as a possible solution for ultrasound bone tissue characterization.
