Improved non-local self-similarity measures for effective speckle noise reduction in ultrasound images

Background and objectiveIn the observed medical ultrasound image, there is always some speckle noise which suppress the details of images and impairs the value of ultrasonography in diagnosis. This work present a novel despeckling method which effectively exploit non-local self-similarity for restoration of corrupted ultrasound images. The proposed approach consist of three stages. First, an improved optimized Bayesian non-local means (OBNLM) filter in which pixel patch is represented by a new vector form is used to get an preliminary estimation of noise-free image. Then, a new index called redundancy index of each pixel patch is calculated for determining which areas in image have low redundancy. Finally, another new vector form is used to represent pixel patch in areas with low redundancy obtained in second stage to recalculate filtered output, and the recalculated output is superimposed on preliminary estimation to generate final result of proposed method. MethodsThe performance of proposed approach is evaluated on simulated and real ultrasound images. The experiments conducted on various test image illustrate that our proposed algorithm outperforms the various classic denoising algorithms included block matching 3-D (BM3D) and optimized Bayesian non-local means filter. ResultsThe objective evaluations and subjective visual inspection of denoised simulated and real ultrasound images demonstrate that the proposed algorithm can achieve superior performance than previously developed methods for speckle noise suppression. ConclusionsThe combined use of two new representations improve denoising and edge preserving capability of proposed filter apparently. The success of proposed algorithm would help in building the lay foundation for inventing the despeckling algorithms that can make fuller use of information in images.

Potential value of three-dimensional ultrasonography in diagnosis of diabetic nephropathy in Chinese diabetic population with kidney injury

BackgroundTo explore the potential value of three-dimensional ultrasonography (3DUS) and contrast-enhanced ultrasound (CEUS) in the diagnosis of diabetic nephropathy (DN) in Chinese diabetic patients with kidney injury.MethodsPatients with type 2 diabetes mellitus and kidney injury in our hospital were enrolled, and the clinical characteristics as well as the laboratory data of patients were collected; 3DUS and CEUS were used to evaluate the morphological structure and blood perfusion of kidneys. Eligible patients were categorized into two groups based on renal biopsy results: DN group and non-diabetic renal diseases (NDRD) group. Correlation analysis and logistic regression analysis were applied to identify the risk factors of DN development.ResultsA total of 115 patients aged from 24 to 78 years old were recruited in the experiment, of which 64 patients (55.65%) and 51 patients (44.35%) were in the DN group and NDRD group, respectively. After correction to CKD stage, BMI and right kidney volume index were retained to identify patients with DN. The ROC of the logistic regression model had an AUC of 0.703 (95% CI: 0.591–0.815) and it was higher than both indicators.Conclusion3DUS has potential value in the diagnosis of diabetic nephropathy in Chinese diabetic population with kidney injury and may act as an auxiliary diagnosis for DN. More prospective and well-designed studies with larger samples are needed to verify the result.

Added Value of Ultrasonography in Diagnosis of Rotator Cuff Injury

Abstract Background: Shoulder pain is one of the commonest musculoskeletal complaints presented to orthopedics and rheumatologists. Shoulder is a joint commonly affected by degenerative changes, overuse and traumatic lesions. Aim of Study: The purpose of this study is to evaluate the role of dynamic high resolution ultrasonography in the detec-tion of rotator cuff muscle injury, to find out the value added by dynamic ultrasonography to the static examination of such cases and to evaluate the value added by dynamic ultrasonogra-phoy to the management of the disease. This is compared to MRI which we considered as a standard to our cases. Material and Methods: This prospective study included 35 patients who were referred to the Radiology Department with clinically suspected rotator cuff injury. After detailed clinical examination, US examination of the involved shoulder was performed together with an examination of the contralat-eral normal shoulder, followed by MRI of the symptomatic shoulder in all 35 patients. The MRI findings were considered as final. Sensitivity and specificity for ultrasound in rotator cuff injuries was calculated with correlation with MRI. Results: In the present study, the majority of patients were in age group 18-57 years. A total of 35 patients were diagnosed as having rotator cuff muscle abnormality on US and MRI. In the diagnosis of rotator cuff muscle tear, the strength of agreement between US and MRI was good. Conclusion: Ultrasound of the shoulder show promising results in diagnosis of rotator cuff muscle injury and acromi-oclavicular join pathology. A wide viability, cost effectiveness and better tolerability of US make it amodality of first choice for evaluation in rotator cuff muscle pathology.

Ultrasonography in Detection of Renal Calculi in Children; a Systematic Review and Meta-analysis.

Although numerous studies have been done to evaluate the diagnostic value of ultrasonography in diagnosis of renal calculi in children, there is still no consensus. Therefore, in the present systematic review and meta-analysis, we aimed to evaluate the diagnostic accuracy of ultrasonography in identifying renal stones in children. A comprehensive search of the electronic databases including Medline, Embase, Scopus and Web of Science was conducted up to July 2019. Diagnostic accuracy studies in children were included. Data was summarized and pooled. Area under the curve (AUC), sensitivity, specificity, diagnostic score and diagnostic odds ratio were reported with 95% confidence interval (95% CI). Data from 7 articles were included. Pooled analysis showed that the area under the curve of ultrasonography in diagnosis of pediatric renal calculi was 0.94 (95% CI: 0.92 to 0.96). The sensitivity and specificity of this diagnostic modality were 0.80 (95% CI: 0.70 to 0.87) and 1.00 (95% CI: 0.84 to 1.00), respectively. Diagnostic score and diagnostic odds ratio of ultrasonography in detection of renal calculi were 110.32 (95% CI: 2.88 to 19.76) and 82362.41 (95% CI: 17.80 to 3.8 × 108), respectively. Overall, the low level of evidence indicates that sensitivity and specificity of ultrasonography in detecting renal calculi in children are 80% and 100%, respectively. However, due to the serious limitations of the included studies, well-designed prospective diagnostic accuracy studies are recommended for future studies.

The incremental value of ultrasound in detection of subclinical peripheral enthesitis in patients with spondyloarthritis

IntroductionInflammatory enthesitis is a hallmark in Spondyloarthritis (SpA). It is detected by clinical examination but lacks sensitivity and reliability. Ultrasonography (US) is more accurate in detecting enthesitis. Aim of the workTo evaluate the value of US in diagnosis of enthesopathy in SpA and assess its relation compared to clinical assessment. Patients and methodsThirty-one SpA patients were subjected to history-taking, clinical examination, laboratory investigations, clinical and US assessment of the same entheseal points. ResultsThe patients mean age was 41.2 ± 2.4 years (28–68 years); 23 males and 8 females. The mean disease duration was 10.4 ± 3.3 years (2 months to 20 years). 12 cases had psoriatic arthritis (PsA), 12 ankylosing spondylitis (AS) and 7 had reactive arthritis (ReA). Most commonly affected entheses in lower limbs were Achilles tendons (right; 70% and left; 80%), while in the upper limbs were supraspinatus tendons (right; 65% and left; 35%). A significant difference was found between clinical and US examination of enthesitis as 19% of examined entheses were abnormal clinically, while 57% with US. Significant agreement was found between clinical and ultrasound examination in detection of enthesitis at supraspinatus with maximum odd ratios for calcifications 72 and erosions 16. Sensitivity of US was 91.9%, while specificity was 83.7%. ConclusionUltrasonography is superior to clinical examination in detection of enthesitis in SpA patients with good sensitivity and specificity. Enthesitis is common in upper limbs as it is in lower limbs; pathological findings and predictive values of calcifications and erosions were high at entheses of upper limbs especially supraspinatus.

Clinical Value of Ultrasonography in Diagnosis of Pulmonary Embolism in Critically Ill Patients.

Pulmonary embolism (PE) is a clinical emergency that will increase the mortality if complicated with unstable hemodynamics. Because of its nonspecific clinical symptoms, it's a great challenge to make a PE diagnosis. The golden standard to diagnose PE is computed tomography of pulmonary artery (CTPA), but a diagnosis of PE also composed of evaluation of PE risk factors, possibilities, and risk stratification. Ultrasonography may detect right ventricle strain related to hemodynamic change, intravascular thrombosis, thrombosis in right heart or pulmonary arteries, pulmonary infarction, and local pleural effusion. Combination of ultrasound and traditional PE possibility evaluation score may further improve the pretest probability of CTPA. A comprehensive ultrasonography may sometimes rule out PE and may disclose other causes for the clinical situations. A heart-lung-vessel-integrated multiorgan ultrasonography can help with the diagnosis of PE and so should be a necessary weapon for the physicians.

Ultrasonic diagnostics of Hirschsprung’s disease in adults

Aim. To study the possibilities of hydrosonography for the differential diagnosis of Hirschsprung’s disease. Methods. The results of the examination of five patients with histologically confirmed diagnosis of Hirschsprung’s disease, 19 patients with slow transit constipation and 10 healthy volunteers are presented. Rectal ultrasonography was performed after retrograde colon filling with saline. Rectal lumen width, thickness and structure of the rectal mucosa and muscular layer were evaluated. The place of transition of rectal ampoule into the anal canal was thoroughly examined to determine rectal anal inhibitory reflex. Results. The following ultrasonic signs of Hirschsprung’s disease were identified: rectal wall thickening up to 6±0,7 mm due to muscular layer hypertrophy, hyperechoic mucosa, rectal lumen widening up to 60±5 mm. A high predictive value of ultrasonography for diagnosis of rectal anal inhibitory reflex absence in Hirschsprung’s disease (sensitivity 100%, specificity 96.7%, accuracy 97.1%). Advantages of the examination are obviousness and technical simplicity. With no introduction of a balloon, electrodes or ultrasonic detector into the rectal lumen, the results of examination can hardly be biased or miscomprehended. Conclusion. Hydrosonography might be used in diagnosis of Hirschsprung’s disease, this method facilitates the differential diagnosis of Hirschsprung’s disease and other forms of chronic constipation and contributes to the correct choice of treatment strategy.

Clinical value of prenatal ultrasonography in diagnosis of fetal abnormalities in fertilization-embryo transfer during early trimester

Objective To evaluate the value of prenatal ultrasonography in diagnosis of in vitro fertilization-embryo transfer(IVF-ET) fetal abnormalities during early trimester.Methods A total of 685 IVF-ET pregnant women received Doppler color ultrasound in our hospital during 11-13+6 weeks of pregnancy from January 2010 to December 2010;the number of fetal,polyembryony chorion,and gestational age were examined;and the abnormal structures were screened.Based on findings of sonographic markers,chorionic villi sampling was done for some fetals.Amniocentesis or selective reduction was done when triplet or one of the twins found with lethal abnormality.All the cases were followed up for pregnancy process and clinical results.Results Among the 685 IVF-ET pregnant women,440 had singleton pregnancy(64.23%),244 had twin pregnancy(35.62%),and only one had triplet pregnancy(0.15%).Seven fetal abnormalities were detected in singleton pregnancies during early trimester,and five cases were clinically confirmed.Six fetal abnormalities were detected in twin pregnancies during early trimester,and three cases were clinically confirmed.Excluding the triplet pregnancy,the total incidence rate of abnormal fetal was 0.86%(8/928),with two cases confirmed by chromosomal abnormality screening and two cases receiving selective reduction operation.Conclusion Standardized prenatal ultrasonography during early trimester(11-13+6 weeks) can improve the accurate screening rate of fetal abnormalities for IVF-ET pregnancy,and can help to deal with multiple pregnancy and abnormal fetals.

Value of ultrasonography in diagnosis of pediatric vocal fold paralysis

Objectives To investigate the appearance of the pediatric larynx on ultrasound images and the diagnostic potential of ultrasound in cases of pediatric vocal fold paralysis. Methods First, we confirmed the ultrasonographic features of the laryngeal landmarks in 2 pediatric cadaveric larynxes. Secondly, 45 children were enrolled in a clinical study (13 patients with vocal fold paralysis and 32 normal children). Quantitative analysis of vocal fold mobility was carried out by measuring the maximum glottic angle (MGA) and vocal fold-arytenoid angle (VAA). Results All the paralyzed vocal folds showed abnormal mobility, and were flaccid during breathing and phonation. The rima glottis appeared as a hyperechoic air-column band in ultrasound images during phonation. The mean value of the MGA was 61.47 ± 9.00 in the normal larynx and 42.25 ± 10.41 in the paralyzed larynx. In the affected side of the paralyzed larynx, the VAA in maximum abduction was smaller than that in the normal larynx or in the unaffected side. The median difference of the VAA between maximum abduction and maximum adduction was less than that in the normal larynx. The kappa value was 0.96. Conclusion MGA and VAA are quantitative indicators of vocal fold immobility. Ultrasound is a reliable method of diagnosis of pediatric VFP. To diagnose VFP from an ultrasound image, the criteria are: (1) abnormal mobility (this was the most important and direct evidence), (2) hyperechoic air-column band of the glottic rima during phonation, (3) flaccid vocal fold and (4) asymmetry of the glottal structures.
