Ultra‐High Frequency Ultrasound Imaging and Quantification of Microvascular Flow in Xenograft Renal Cell Carcinoma in an Avian Chorioallantoic Membrane Model

Journal of Ultrasound in Medicine, EarlyView.
Patient‐derived xenograft (PDX) tumor models initiated in avian chorioallantoic membranes (CAM) are under investigation to evaluate the effectiveness of therapeutic options with the objective of personalizing treatments. CAM PDXs paired with ultra‐high frequency ultrasound (UHFUS) imaging could potentially constitute prospective high throughput assays ...

Pelvic Ultrasound for Predicting Endometrial Neoplasia in Premenopausal Abnormal Uterine Bleeding

Journal of Ultrasound in Medicine, EarlyView.
Objectives Although ultrasound is the first line imaging modality for abnormal uterine bleeding (AUB), there is a lack of consensus on its predictiveness for premenopausal endometrial pathology. This study aims to determine the predictiveness of pelvic ultrasound for endometrial neoplasia and cancer precursor lesions in premenopausal patients ...

Understanding the Concept of Self‐Performed Ultrasound: A Scoping Review

Journal of Ultrasound in Medicine, EarlyView.
Self‐performed ultrasound is an emerging technology that facilitates adept self‐scans in untrained hands. Inspired by self‐performed imaging in space for more prompt diagnosis and therapy, it has the potential to accurately monitor chronic conditions remotely. However, the lack of supervision and physical restraints can hinder its usability.

[Valve insufficiency. Evaluation using color Doppler].

Revista portuguesa de cardiologia : orgao oficial da Sociedade Portuguesa de Cardiologia = Portuguese journal of cardiology : an official journal of the Portuguese Society of Cardiology, 1990
Color Doppler is undoubtedly in the last years main breakthrough in the non invasive definition of regurgitant flows. The detection and quantification of the regurgitant streams, the study of their spatial distribution, the appraisal of their relationships, to anatomical structures, meant a new sight of the physiopathology of valvular insufficiencies ...

Clinical Significance of Intratumoral Blood Flow in Cervical Carcinoma Assessed by Color Doppler Ultrasound

, 2008
　　Background. Much evidence has suggested that vascular density reflects the clinical behavior of cancer. In this study, the intratumoral blood flow in cervical carcinomas was assessed by transvaginal color Doppler ultrasound, and its clinical ...

A Standardized Technique for Ultrasound–MRI Fusion Imaging of the Carotid Artery for Vascular Assessment

Journal of Ultrasound in Medicine, EarlyView.
Purpose To describe a reproducible ultrasound–magnetic resonance imaging (MRI) fusion imaging technique developed for quantitative assessment of carotid wall strain and plaque morphology. Methods MRI volumes (Oblique T2 Cube) were imported into the Sequoia ultrasound system equipped with an electromagnetic tracking module.

Transvaginal Strain Elastography Methodology in Deep Endometriosis

Journal of Ultrasound in Medicine, EarlyView.
Objectives Transvaginal strain elastography (SE) has emerged as a complementary technique to transvaginal ultrasound for deep endometriosis (DE) evaluation by exploiting tissue stiffness between lesions and surrounding structures. However, its clinical adoption remains limited by marked methodological heterogeneity across studies.

Efficacy of Ultrasound‐Guided Intercostal Nerve Block With Liposomal Bupivacaine for Treating Postherpetic Neuralgia in Adult Patients

The Kaohsiung Journal of Medical Sciences, EarlyView.
ABSTRACT The study aimed to investigate the efficacy of ultrasound‐guided intercostal nerve block (ICNB) with liposomal bupivacaine (LB) comparing ropivacaine‐dexamethasone (RD) for treating postherpetic neuralgia (PHN) in adult patients. A total of 108 patients were randomized 1:1 to receive ICNB with LB or ICNB with RD.
