Imaging of the J-pouch
Ileal pouches have drastically improved the quality of life in patients requiring total proctocolectomy. There are unique imaging characteristics of the pouch and its complications that radiologists should be familiar…
Multimodality Imaging of Small Bowel Crohn Disease
Computed tomography enterography, magnetic resonance enterography, and bowel ultrasound are complementary tools central to diagnosing and monitoring Crohn disease. These modalities can identify active inflammation, penetrating, and stricturing disease. Crohn…
Pulse-Echo Ultrasound for Quantitative Measurements of Two Uncorrelated Elastic Parameters
Abstract Objective This paper describes the relationship between elastic tissue properties and strain and presents an initial investigation of pulse-echo ultrasound to measure two uncorrelated elastic parameters in tissue-mimicking phantoms….
Ultrasound and Gold Nanoparticles Improve Tissue Repair for Muscle Injury Caused by Snake Venom
Abstract Objective To develop a treatment that enhances recovery from envenomation-induced lesions caused by Bothrops jararaca venom by using ultrasound in combination with gold nanoparticles (GNPs). Methods A total of…
Perioperative Detection of Cerebral Fat Emboli From Bone Using High-Frequency Doppler Ultrasound
Abstract Objective Fat embolism syndrome and cerebral fat emboli are rare yet serious conditions arising from systemic distribution of bone marrow emboli. Emboli are known to produce high-intensity transient signals…
Quantitative Ultrasound for Periodontal Soft Tissue Characterization
Abstract Objective Periodontal diseases are a spectrum of inflammatory diseases that affect 45.9% of adults aged ≥30 years in the United States Current standard of care in clinics for the…
Estimation of In Vivo Human Carotid Artery Elasticity Using Arterial Dispersion Ultrasound Vibrometry
Abstract Objective Arterial stiffening serves as an early indicator for a variety of cardiovascular diseases. Arterial Dispersion Ultrasound Vibrometry (ADUV) is a method that leverages acoustic radiation force to stimulate…
Ex VivoDemonstration of a Novel Dual-Frequency Ultrasound Method for Quantitative Measurements of Liver Fat Content
Abstract Objective The rise in metabolic dysfunction–associated steatotic liver disease prevalence, closely linked with metabolic syndromes and obesity, demands accurate, cost-effective diagnostic methods for early-stage fat quantification in the liver….
Attenuation Measuring Ultrasound Shearwave Elastography (AMUSE) as Noninvasive Imaging Biomarker for Liver Acute Cellular Rejection
Abstract Objective There are over 9000 liver transplants in the United States per year, with acute cellular rejection (ACR) being a prevalent early post-transplant complication (20%–40%) treated using corticosteroids. Ischemia-reperfusion…
Design of a Phantom Mimicking Rectal Lymph Nodes for Magnetomotive Ultrasound
Abstract Objective Durable and stable phantoms for verifying and validating the new magnetomotive ultrasound technique are lacking. Here we propose a phantom design to address this need. Methods A mixture…
