Study of Risk Factors and Image Findings of Isolated Abdominal Incidentally Detected Aortic Dissection

Journal of Clinical Ultrasound, Volume 53, Issue 3, Page 429-435, March/April 2025.
We detect the risk factors and image characteristics of incidentally detected IAAD. Independent risk factors of IAAD included fatty liver and smoking. In the ultrasound findings of IAAD, an intimal flap was frequently observed. In the CT scan, displacement of intimal calcifications was frequently observed. For suspected IAAD, the abdominal aorta should

Sonographic Anatomy and Imaging of the Extracranial Component of the Hypoglossal Nerve (CNXII)

Journal of Medical Radiation Sciences, EarlyView.
The hypoglossal nerve (HN) provides motor innervation to tongue muscles responsible for tongue movement, speech, mastication, swallowing, respiratory functions and management of oral secretions. The intracranial component of the HN can be demonstrated on magnetic resonance imaging and the extracranial component can be demonstrated with sonographic ...

Sonographic localisation of lymph nodes suspicious of metastatic breast cancer to surgical axillary levels

Journal of Medical Radiation Sciences, Volume 72, Issue 1, Page 119-138, March 2025.
Sonographic imaging is used to identify the presence, number and location of malignant lymph nodes. Axillary lymph nodes suspicious of harbouring breast cancer metastasis can be localised to three surgical axillary levels. This paper will unpack the axillary anatomy, muscular sonographic landmarks, surgical axillary lymph node levels and the ...

Evaluation of Hepatic Steatosis and Fibrosis in Steatotic Liver Disease Ultrasound‐Derived Fat Fraction (UDFF) and Auto pSWE by Using Deep Abdominal Transducer (DAX) and Liver Biopsy Correlation

Journal of Ultrasound in Medicine, EarlyView.
Objectives To evaluate the diagnostic performance of ultrasound‐derived fat fraction (UDFF) in detecting and grading hepatosteatosis using liver histology as the reference, and to assess the effectiveness of point shear wave elastography (pSWE), UDFF, and auto‐pSWE in diagnosing steatohepatitis and detecting fibrosis in metabolic dysfunction‐associated

Time‐resolved mapping of myocardial stiffness using 2D multifrequency spiral MR elastography with and without external vibration

Magnetic Resonance in Medicine, EarlyView.
Abstract Purpose There is a clinical need for stiffness mapping of the heart; however, current cardiac magnetic resonance elastography (cMRE) has limited spatiotemporal resolution. Therefore, we developed 2D spiral multifrequency MRE of the human heart and conducted a study to analyze the consistency and reproducibility of motion‐encoding and stiffness

Quantitative Muscle Ultrasound: A Non‐Invasive Biomarker for Monitoring Duchenne Muscular Dystrophy

Muscle &Nerve, EarlyView.
ABSTRACT Introduction/Aims Quantitative muscle ultrasound (QMUS) shows promise as a non‐invasive biomarker for monitoring functional status in Duchenne muscular dystrophy (DMD). We evaluated the correlation between QMUS in various muscles and functional capacity assessments.

Learning‐Based Rapid Phase‐Aberration Correction and Control for Robot‐Assisted MRI‐Guided Low‐/High‐Intensity Focused Ultrasound Treatments

Journal of Field Robotics, EarlyView.
ABSTRACT Magnetic resonance imaging (MRI)‐guided focused ultrasound (MRg‐FUS) is an effective and noninvasive procedure for treating diseases such as neurological disorders. Phase adjustment on ultrasound transducers can only achieve a limited focal‐spot steering range.

Lipid Microparticle‐Based Phantoms Modeling Hepatic Steatosis for the Validation of Quantitative Imaging Techniques

Small Methods, EarlyView.
This paper presents a novel method for creating ultrasound phantoms that accurately replicate fat vesicle sizes encountered in Metabolic Dysfunction‐Associated Steatotic Liver Disease (MASLD). This approach can improve the understanding of liver fat measurement by creating ultrasound phantoms that link different quantitative imaging techniques to ...

Acoustically Responsive Nanofibrous Scaffolds with 3D Hierarchy for Tympanic Membrane Regeneration

Small Structures, EarlyView.
This study investigates the influence of molecular, hierarchical, and acoustical stimulation on biofabricated tympanic membrane (TM) scaffolds within a custom‐built bioreactor mimicking the native tissue niche. It demonstrates that synergistically integrated bioactive agents, 3D hierarchical patterns, and sound waves promote the formation of an aligned

The Effects of COVID‐19 on Voice

World Journal of Otorhinolaryngology - Head and Neck Surgery, EarlyView.
ABSTRACT The COVID‐19 pandemic had profound effects on vocal health, impacting both infected individuals, professional voice users and essential workers. The objective of this paper was to explore the multifaceted nature of dysphonia associated with COVID‐19, arising from both direct and indirect consequences of the pandemic.
