OBJECTIVE: To conduct the preliminary positioning and qualitative research of high-frequency ultrasonic imaging at Ashi points (including tender points and trigger points) in neck-type cervical spondylosis and explore the relevant law so as to provide the evidence for the selection of acupuncture scheme. METHODS: Thirty patients in compliance with the diagnostic criteria of neck-type cervical spondylosis were selected. The trigger points, tender points and placebo points were positioned on any of the three available oriented lines...

Following an ischemic event post systolic shortening (PSS) may occur. We investigated the association between PSS in patients with ST-segment elevation myocardial infarction (STEMI) following primary percutaneous coronary intervention (pPCI) and occurrence of cardiovascular events at follow-up. A total of 373 patients admitted with STEMI and treated with pPCI were prospectively included in the study cohort. All patients were examined by echocardiography a median of 2 days after admission (interquartile range, 1-3 days)...

BACKGROUND: Congenital diaphragmatic hernia (CDH) is a structural birth defect associated with pulmonary hypoplasia and pulmonary arterial hypertension (PAH). We hypothesize that echocardiography provides a method to assess real-time right ventricle (RV) function, remodeling, and pulmonary artery (PA) flow. MATERIALS AND METHODS: Slit3 wild-type (WT) (n = 6) and knockout (KO) (n = 5) mice were analyzed at 2-3 months of age. Mice were anesthetized using isoflurane...

BACKGROUND: Left atrial (LA) dysfunction, expressed as impaired LA deformation using two-dimensional (2D) strain imaging, has been observed in association with rheumatic mitral stenosis (MS). However, the clinical role of speckle tracking echocardiography (STE)-derived LA strain has rarely been studied in MS. AIM: This study aimed to identify the determinants of New York Heart Association (NYHA) functional class in patients with mitral stenosis and to investigate the relationship between left atrial deformation as measured by two-dimensional STE-derived LA strain and heart failure symptoms...

INTRODUCTION: Intubation is a frequently performed procedure in emergency medicine that is associated with significant morbidity and mortality when unrecognized esophageal intubation occurs. However, it may be difficult to visualize the endotracheal tube (ETT) in some patients. This study assessed whether the addition of color Doppler was able to improve the ability to visualize the ETT location. METHODS: This study was performed in a cadaver lab using three different cadavers chosen to represent varying neck circumference...

The cerebral hypoperfusion caused by chronic progressive stenosis or occlusion of intracranial arteries in moyamoya disease can be treated by direct bypass or indirect revascularization procedures. The extent of collaterals from the external carotid artery (ECA) after indirect revascularization surgery is the key point of angiographic follow-up, and the invasiveness of angiography impelled us to investigate the role of ultrasonography in the evaluation of collaterals. We hypothesized that the collaterals shown on angiography might produce corresponding hemodynamic changes in color Doppler ultrasonography...

Background: Acute effects of positive airway pressure (PAP) [including continuous PAP (CPAP) and adaptive servo-ventilation, an advanced form of bi-level PAP] on functional mitral regurgitation (fMR) in patients with heart failure (HF) with left ventricular (LV) systolic dysfunction remain unclear. Thus, whether PAP therapy reduces fMR in such patients with HF was investigated. Methods and Results: Twenty patients with HF and LV systolic dysfunction defined as LV ejection fraction (LVEF) <50% (14 men; mean LVEF, 35...

AIM: To explore the ability of superb microvascular imaging (SMI) in differential diagnosis of focal liver lesions (FLLs) and to compare SMI morphology findings to those of color Doppler ultrasound and enhanced imaging. METHODS: Twenty-four patients with 31 FLLs were included in our study, with diagnoses of hemangioma (HE) (n = 17), hepatocellular carcinoma (HCC) (n = 5), metastatic lesions (n = 5), primary hepatic lymphoma (n = 1), focal nodular hyperplasia (FNH) (n = 2), and adenoma (n = 1)...

Ovarian cancer is the most frequent cause of death from all gynaecological malignancies because of its insidious onset, vague symptoms and late presentation. This cross-sectional study was carried out on purposively selected 43 patients with suspected ovarian tumor in the Department of Radiology and Imaging in collaboration with the Department of Gynaecology and Obstetrics and Department of Pathology, Mymensingh Medical College Hospital, Bangladesh from January 2015 to December 2016 to assess the diagnostic performance of color Doppler ultrasonography and CA-125 in a combination described as Novel Index in detection of ovarian tumor...

Purpose: The distinction between active inflammation and fibrosis of the bowel wall is essential for therapeutic decisions in stricturing Crohn's disease. We aimed to assess whether real-time elastography (RTE) with strain ratio measurement could be useful in differentiating fibrotic from inflamed bowel strictures and to evaluate the possible relationship between US techniques and the histology of the stenotic bowel wall. Materials and methods: Bowel ultrasonography (including RTE, color-Doppler and CEUS examination) was prospectively evaluated in 26 patients with symptomatic stricturing Crohn's disease, before surgery...

Aim: A case of asymptomatic aneurysm of spontaneous portosystemic venous fistula (SPVF) with the radiologic findings is described. Background: Although advances and more widespread use of ultrasound (US) and computed tomog -raphy angiography (CTA) have enabled more detection of SPVF in the liver, it is a rare entity. Case report: A 49-year-old male was referred to our hospital's nephrology outpatient clinic due to hypertension. Abdominal sonography examination detected a well-defined cystic lesion adjacent to the middle hepatic vein in the liver...

Background The objective of the study was to determine the long-term outcomes, including mitral restenosis and regurgitation, after successful percutaneous transvenous mitral commissurotomy (PTMC). Methods This cross-sectional prospective study was conducted at the cardiology department of Lady Reading Hospital, Peshawar, Pakistan, from January 2007 to December 2009. A total of 84 patients were followed up for a period of 96 months. Pre and post percutaneous transvenous mitral commissurotomy echocardiography was done on the mitral valve area (MVA) using two-dimensional (2D) and color doppler echocardiography...

Lymphangioma is a benign congenital malformation. The extremely rare and atypical localization of a lymphangioma in the chest wall was the real motive for the present case study. A 5-year-old boy was admitted to the Emergency Department of the 1st Department of Pediatric Surgery, Aristotle University of Thessaloniki, due to the presence of a mildly painful swelling in the left lateral chest wall, which was first noticed three months ago, after a blunt injury during sport. Physical examination revealed the presence of a palpable, spherical, painful, nut-sized subcutaneous lesion in the left lateral chest wall, respectively, with the anterior axillary line, at the height of the 6th to 7th intercostal space...

Ultrasound is widely used in the diagnosis and follow-up of chronic arthritis. We present an evaluation of a novel automatic ultrasound diagnostic tool based on image recognition technology. Methods used in developing the algorithm are described elsewhere. For the purpose of evaluation, we collected 140 ultrasound images of metacarpophalangeal and proximal interphalangeal joints from patients with chronic arthritis. They were classified, according to hypertrophy size, into four stages (0-3) by three independent human observers and the algorithm...
