The correlation between prenatal ultrasound and MRI in isolated periventricular pseudocysts: Analysis of 10 years' experience at the University Hospital of Angers
CONCLUSION: The finding of periventricular cysts in antenatal ultrasound should lead to a reference ultrasound, a key procedure for distinguishing between SEPC and FHC. In our study, no additional benefit from MRI and TFU was established for the evaluation of FHC. These findings should be considered as normal variants, thus limiting pre- and postnatal investigations. The visualization of SEPC, THC, or a parenchymal abnormality on the reference ultrasound should lead to an additional MRI being performed and a personalized follow-up of the child.PMID:37704521 | DOI:10.1016/j.arcped.2023.06.010

Translational strategies and systems biology insights for blood-brain barrier opening and delivery in brain tumors and Alzheimer's disease
Biomed Pharmacother. 2023 Sep 11;167:115450. doi: 10.1016/j.biopha.2023.115450. Online ahead of print.ABSTRACTThe blood-brain barrier (BBB) plays a critical role in determining the effectiveness of systemic treatments for brain diseases. Over the years, several innovative approaches in BBB opening and drug delivery have been developed and progressed into clinical testing phases, including focused ultrasound (FUS) with circulating microbubbles, mannitol-facilitated delivery of anti-neoplastic drugs, receptor-mediated transcytosis (RMT) by antibody-drug conjugates (ADCs), and viral vectors for gene therapy. We provided a com...

Comparison of ultrasound elastography, magnetic resonance elastography and finite element model to quantify nonlinear shear modulus
Phys Med Biol. 2023 Sep 13. doi: 10.1088/1361-6560/acf98c. Online ahead of print.ABSTRACTThe aim of this study is to validate the estimation of the nonlinear shear modulus (A) from the acoustoelasticity theory with two experimental methods, ultrasound (US) elastography and magnetic resonance elastography (MRE), and a finite element method.
Experiments were performed on agar (2%) - gelatin (8%) phantom considered as homogeneous, elastic and isotropic. Two specific setups were built to ensure a uniaxial stress step by step on the phantom, one for US and a nonmagnetic version for MRE. The stress was controlled identic...

Deep learning for fast denoising filtering in ultrasound localization microscopy
Phys Med Biol. 2023 Sep 13. doi: 10.1088/1361-6560/acf98f. Online ahead of print.ABSTRACTSuper-resolution ultrasound (SR-US) microvascular imaging has important implications in the diagnosis of tumor growth and metastasis. Addition of a denoising filter step in ultrasound localization microscopy (ULM) imaging has been shown to effectively reduce the error localizations of microbubbles (MBs) and improve the resolution of SR-US imaging. However, previous image-denoising methods (e.g., block-matching 3-D, BM3D), required long data acquisition and processing times，which made ULM only able to be processed offline. To overcome...

Magnetic Localization of Breast Lesions: A Large-Scale European Evaluation in a National Cancer Institute
CONCLUSIONS: Image-guided localization with magnetic seeds is an easy, safe, reliable, and effective method for localizing nonpalpable breast lesions. Both radiologists and surgeons agreed that the technology was intuitive to use and that it can be widely applied in preoperative localization in breast units.PMID:37704563 | DOI:10.1016/j.clbc.2023.08.004

Evaluation of the efficacy of ultrasound-guided radiofrequency ablation of papillary thyroid microcarcinoma after one year
CONCLUSION: Ultrasound-guided radiofrequency ablation is safe and effective for treating single-focus micropapillary thyroid carcinoma while retaining thyroid function, with few and minor complications, which can be used as an ideal surgical option.PMID:37704471 | DOI:10.1016/j.asjsur.2023.08.218

Nondeformed Ultrasound Image Production Method for Ultrasound-Guided Radiotherapy
Conclusion: The pixel displacement-based deformation correction method can solve the limitation imposed by image deformation on image alignment in US-guided radiotherapy. Compared with USdef, the alignment results of USrev with CT were better.PMID:37700675 | PMC:PMC10501062 | DOI:10.1177/15330338231194546

Intravascular Ultrasound in Detection of Bridging Stent Graft Instability During Fenestrated and Branched Endovascular Aneurysm Repair Procedures: A Multicentre Study on 274 Target Vessels
CONCLUSION: This study suggests that IVUS is a safe and potentially valuable adjunct imaging technology for intra-operative detection of TVV instability. Further long term investigations on larger cohorts are required to validate these promising results and to compare IVUS with alternative technologies in terms of efficiency, radiation exposure, procedural time, and costs.PMID:37704100 | DOI:10.1016/j.ejvs.2023.09.009

Synergetic Effect of Memecylon edule Mediated AuNPs and Ultrasound Therapy as a Promising Approach Against Proliferation of Pediatric Acute Leukemia Cell Lines
AbstractIn the present work, an easy one-pot environmentally friendly method is demonstrated where the extract ofMemecylon edule was utilized for the synthesis of gold nanoparticles (Au NPs) through the reduction of chloroauric acid (HAuCl4). The synthesized NPs were studied using various spectroscopic and microscopic techniques. UV-visible (UV-Vis) results indicated the formation of AuNPs with optical absorption peak found at 537 nm. Transmission electron microscopy (TEM) and X-ray diffraction (XRD) analysis confirmed the formation of AuNPs with size ranges from 25 to 30 nm. FTIR results confirmed the capping of AuNPs wit...

Continuous Tunneled Infraclavicular Nerve Catheter for Palliative Management of Critical Limb Ischemia: A Case Report
We describe the successful use of a continuous local anesthetic infusion via an infraclavicular nerve catheter to control severe refractory ischemic upper limb pain in a patient with metastatic lung cancer for whom surgical and pharmacological intervention was unsuccessful. As her opioid requirements increased due to worsening ischemic pain, she subsequently developed opioid toxicity, hence prompting the palliative use of a tunneled infraclavicular nerve catheter under ultrasound guidance to minimize opioid requirements. Her opioid requirements tailed down subsequently with the successful insertion of the infraclavicular n...

The exercise pressor reflex - a pressure-raising mechanism with a limited role in regulating leg perfusion during locomotion in young healthy men
J Physiol. 2023 Sep 12. doi: 10.1113/JP284870. Online ahead of print.ABSTRACTWe investigated the role of the exercise pressor reflex (EPR) in regulating the haemodynamic response to locomotor exercise. Eight healthy participants (23 ± 3 years, V ̇ O 2 max ${\dot V_{{{\mathrm{O}}_{\mathrm{2}}}{\mathrm{max}}}}$ : 49 ± 6 ml/kg/min) performed constant-load cycling exercise (∼36/43/52/98% V ̇ O 2 max ${\dot V_{{{\mathrm{O}}_{\mathrm{2}}}{\mathrm{max}}}}$ ; 4 min each) without (CTRL) and with (FENT) lumbar intrathecal fentanyl attenuating group III/IV locomotor muscle afferent feedback and, thus, the EPR. To avoid differ...
