Engineered molecular diagnostic strategies for hepatocellular carcinoma: Integrating flexible photonic barcodes, liquid biopsies, and AI‐enhanced sensing platforms

FlexMat, EarlyView.
Abstract Early diagnosis of hepatocellular carcinoma (HCC) remains challenging because conventional serum biomarkers, especially alpha‐fetoprotein (AFP), show limited sensitivity for early‐stage disease. Recent progress in engineered molecular diagnostics provides new opportunities to improve HCC detection through integrated material, molecular, and ...

Continuous-Wave Doppler Ultrasound

, 2011
Early noninvasive vascular diagnostic procedures relied heavily on continuous-wave (CW) Doppler ultrasound techniques. Development of CW Doppler instrumentation began in the mid 1950's in Japan with the work of physicist Shigeo Satomura.

Vascular Testing to Overcome Anatomical Contraindication: Fibula Free Flap in Bilateral Peronea Arteria Magna

Head &Neck, EarlyView.
ABSTRACT Background Peronea arteria magna (PAM) is an established contraindication for fibula free flap due to concern for vascular compromise of the lower leg. Methods This is a case of a 74‐year‐old male with a history of multiply recurrent oral cavity cancer who had undergone prior free flap reconstruction who presented with a new oral cavity ...

Superior Labial Artery Mucosal Flap (SLAM) for Reconstruction of Major Lower Lip Mucosal Defects

Head &Neck, EarlyView.
ABSTRACT Background The superior labial artery mucosal (SLAM) flap is a versatile, pedicled axial flap ideally suited for mucosal lining in lower lip reconstruction. Methods This article details the surgical anatomy and technique of the SLAM flap, highlighting its role as a standalone liner or mucosal adjunct to microvascular free tissue transfer in ...

Strain and Shear Wave Elastography in Thyroid Nodules: Tissue Stiffness as a Complementary Risk Marker for Differentiating Benign, Indeterminate, and Malignant Cytology

Head &Neck, EarlyView.
ABSTRACT Objective To evaluate the diagnostic performance of shear wave elastography (SWE) and strain elastography (SE) as complementary techniques to conventional B‐mode ultrasound for differentiating benign, indeterminate, and malignant thyroid nodules. Methods This prospective cross‐sectional study included 208 thyroid nodules evaluated using B‐mode

Using a combination of superb microvascular imaging and other auxiliary ultrasound techniques to increase the accuracy of gray-scale ultrasound for breast masses

BMC Cancer
Background Breast ultrasound is highly sensitive, but its specificity is not as high for detecting malignant lesions. Auxiliary modalities like elastography, Color and Power Doppler ultrasound are used as adjuncts to yield both a high sensitivity and ...

Duplex Doppler ultrasound study of the temporomandibular joint

, 2012
Introduction: The anatomy and physiology of the temporomandibular joint can be studied clinically and by diagnostic imaging. Magnetic resonance imaging (MRI), radiography (X-ray) and computed tomography (CT) have thus for many years contributed to the ...
