Time-course changes in active stiffness of the supraspinatus muscle after arthroscopic rotator cuff repair
ConclusionThe maximal voluntary isometric contraction 12 months postoperatively possibly increased because of improvement in the active stiffness of the anterior superficial region. Active stiffness of the anterior superficial region may improve 6 months rather than 3 months postoperatively because of the different stages of muscle force, structural r epair tendon strength, and remodeling.

The role of endoscopic ultrasound for portal hypertension in liver cirrhosis
AbstractChronic liver disease is still a major problem because disease progression will ultimately lead to liver cirrhosis. Portal hypertension is the hallmark in advanced liver disease management. By establishing portal vein access, endoscopic ultrasound (EUS) has been utilized in various clinical applications. In comparison to standard upper gastrointestinal endoscopy, EUS-Doppler has been shown to be a better modality for detecting esophageal and gastric varices along with peri-esophageal collateral veins, para-esophageal collateral veins, and perforating veins, and may be used to objectively predict the recurrence of b...

Standardization of normal values for cardiac chamber size in echocardiography
AbstractEchocardiography is used worldwide to evaluate cardiac size and function. To determine what values are abnormal, it is essential to establish normal reference values for echocardiography. The current guidelines for chamber quantification specify normative values for cardiac chambers and recommend that gender and body size be taken into account. However, these normative data were established using databases for which a variety of measurement methods were used and the majority of subjects consisted of Whites in Europe and the United States. However, several regional studies from other countries suggest that cardiac s...

How to standardize measurement of global longitudinal strain
AbstractGlobal longitudinal strain (GLS) is a robust and sensitive marker of left-ventricular systolic function, reflecting longitudinal shortening of the ventricle. A growing body of evidence indicates its superiority in identifying subclinical, early alterations in cardiac function compared to traditional markers, such as ejection fraction. Therefore, there is a growing demand to assess GLS in clinical settings, but limited availability on how to obtain GLS accurately and appropriately in the current literature. This review summarizes key aspects of GLS measurement, including image acquisition, post-processing, and train...

Artificial intelligence in the diagnosis of cirrhosis and portal hypertension
AbstractClinically significant portal hypertension is associated with an increased risk of developing gastroesophageal varices and hepatic decompensation. Hepatic venous pressure gradient measurement and esophagogastroduodenoscopy are the gold-standard methods for assessing clinically significant portal hypertension and gastroesophageal varices, respectively. However, invasiveness, cost, and feasibility limit their widespread use, especially if repeated and serial evaluations are required to assess the efficacy of pharmacotherapy. Artificial intelligence describes a range of techniques that allow machines to perform tasks ...

Effectiveness of pulsatility index of carotid Doppler ultrasonography to predict cardiovascular events
ConclusionThe results suggested that carotid PIs were independent predictive factors for further cardiovascular events. In particular, high ECA-PI levels may reflect severe arteriosclerosis. (Source: Journal of Medical Ultrasonics)

Use of aortic point-of-care ultrasound in conventional and emergent echocardiography
AbstractAortic aneurysms expand asymptomatically and rupture lethally. Acute aortic dissection is also a highly lethal cardiovascular emergency and requires prompt recognition. Although cardiovascular ultrasonography has a suboptimal accuracy rate for detecting aortic dissection, it is noninvasive, readily available, and easy to use. Recently, the concept of point-of-care ultrasound (POCUS) refers to the use of portable and/or implemented ultrasound at the patient ’s bedside for diagnostic and therapeutic purposes. Aortic POCUS could become an important tool for aortic aneurysm screening and primary diagnosis of acute ao...

Imaging diagnosis of autoimmune pancreatitis: computed tomography and magnetic resonance imaging
AbstractAutoimmune pancreatitis (AIP) is a pancreatic phenotype of IgG4-related systemic disease. Since its first description in the literature, characteristic imaging features have gradually become known to many clinicians encompassing various specialties in the past quarter century. CT and MRI have been the workhorses for imaging diagnosis of AIP. Typical features include sausage-like swelling of the focal or entire pancreas, duct-penetrating sign, a capsule-like rim of the affected lesions, and homogeneous delayed enhancement or enhanced duct sign after contrast administration, as well as characteristic combined finding...
