Gray Scale Ultrasound, Color Doppler Ultrasound, and Contrast-Enhanced Ultrasound in Renal Parenchymal Diseases
Ultrasound (US), which may be combination of gray scale and spectral Doppler US, color and power Doppler US, with or without microbubble contrast agents, is usually the first imaging modality to be used in renal parenchymal diseases. The most typical appearance of diffuse renal parenchymal diseases on gray scale US is an increased renal cortical echogenicity and increased or reduced corticomedullary differentiation. Spectral Doppler analysis of intrarenal flows may reveal an increase in intrarenal resistive index value greater than 0.70 in native kidneys, and greater than 0.8 in renal transplants. Gray scale US and spectra...

The Evolving Role of Shear Wave Elastography in the Diagnosis and Treatment of Prostate Cancer
To forego misdiagnosis and biopsy-related complications, we explore a novel technique that embraces tissue elasticity to circumvent the current limitations in the accurate, non-invasive detection of prostate cancer. A MEDLINE® database search of literature pertinent to prostate elastography published in the last five years was guided using the following terms: tissue elasticity, ultrasound elastography, strain elastography, magnetic resonance elastography, and shear wave elastography. Ultrasound shear wave elastography (SWE) utilizes the propagation of induced shear waves to provide a quantitative measurement of elasticit...

Translabial Ultrasound in Midurethral Sling (Mesh) Visualization and Erosion Detection in Women With Stress Urinary Incontinence: A Retrospective Pilot Study
Sling erosion is a significant complication of midurethral sling (mesh) placement for stress urinary incontinence, a common pelvic floor disorder. The goal of this retrospective case-control pilot study was to evaluate the performance of translabial ultrasound (TLUS) and magnetic resonance imaging in diagnosing mesh erosion. Therefore, women who underwent surgery in the setting of prior failed midurethral sling for stress urinary incontinence were identified from the hospital database. The case subcohort comprised all women with intraoperatively documented erosion, and the control subcohort comprised an equal number of ran...

Usability of Transthoracic Shear Wave Elastography in Differentiation of Subpleural Solid Masses
In this study, the effectiveness of transthoracic ultrasound elastography in the benign and malign distinction of subpleural/pleural solid lesions was investigated.Between July 2015 and December 2016, 33 consecutive patients with subpleural solid lesions detected via computed tomography (CT) of the thorax were identified and prospectively included in this study. The average for each lesion's shear wave velocity (SWV) value was detected, and benign and malignant lesions' SWV values are statistically compared. The CT and pathology results were used as a reference to compare these values. A receiver operating characteristic a...

Effectiveness of Bedside Lung Ultrasound for Clinical Follow-Up of Primary Spontaneous Pneumothorax Patients Treated With Tube Thoracostomy
In this study, we investigated the efficiency of bedside ultrasound and compared it with x-ray imaging for the clinical follow-up of PSP patients treated with TT.
This is a prospective observational study. After ethical committee approval and written informed consent were obtained, patients who were treated with TT because of PSP were screened. In the follow-up of these patients, a bedside lung ultrasound (BLUS) was performed before every chest x-ray by an emergency physician experienced in performing BLUSs. The performance of BLUSs in detecting free air in the pleural cavity was compared statistically with that of x-rays...

Pulmonary Ultrasound: A New Era in Critical Care Medicine
Pulmonary ultrasonography is a complementary study that is easy to perform at the patient bedside with no need to transfer the patient to special areas. The technique provides information with high sensitivity and specificity for different pathologies. Pulmonary ultrasonography is a very important diagnostic tool in the assessment of lung, pleural, and chest wall diseases. Pulmonary ultrasound provides low-cost analysis, easy real-time reproduction, and safety, all of which have made it a beneficial tool in the diagnostic arsenal available to medical personnel. The purpose of this review was to describe the usefulness of p...

Quantitative Assessment of Palatine Tonsils in Healthy Children and Adolescents With Shear-Wave Elastography
In conclusion, this preliminary work can be used as a reference for the diagnosis of PT diseases. Future comprehensive studies are necessary to establish the role of elastography in the diagnosis of pathologic tissue differentiation confirmed by clinical, laboratory, or pathology analyses.

Experience of Using Shear Wave Elastography Imaging in Evaluation of Undescended Testes in Children: Feasibility, Reproducibility, and Clinical Potential
We aimed to determine the difference in tissue stiffness, which might reflect histologic damage, by comparing the potential of the shear wave elastography (SWE) values of operated undescended testes (OUT) with those of undescended testes (UT) and normal testes. A total of 120 patients (235 testes) were enrolled in the current study. Quantitative SWE values were measured by manually drawing contours of the entire testis structure with a free region of interest. A group of 66 OUT were classified as group A. Operation age and the period passed over the operation time and SWE values were compared among the testes assigned to g...

Ultrasound Elastography Applications in Pediatrics
Ultrasound is one of the most important imaging modalities in pediatric imaging because of its accessibility, portability, lack of ionizing radiation, and ability to generally perform examinations without need for sedation. Ultrasound elastography can measure the stiffness of various tissues. This review article aims to discuss how ultrasound elastography has performed in evaluating multiple pathologies in the pediatric population. The best studied pediatric applications are in liver diseases such as fibrosis, biliary atresia, and hepatic vascular congestion. Measuring muscle stiffness in cerebral palsy is the most promisi...

Carotid Ultrasound Examinations: Indications Correlated With Abnormal Findings
Our purpose was to evaluate the clinical indications for carotid duplex ultrasonography and determine for each indication how often carotid artery disease was identified.
We retrospectively reviewed the consecutive reports for 3191 carotid ultrasound examinations. We tracked 14 indications to determine how often examinations were requested for each indication and correlated each indication with the finding of carotid artery disease.
We found 26.5% of all examinations were abnormal; 17.5% of patients showed internal carotid artery disease; 10.9%, a moderate stenosis; 5.2%, a severe stenosis; and 1.4%, a total occlusion. F...

Experience of Using Shear Wave Elastography Imaging in Superficial Venous Insufficiency of the Lower Extremity
We investigated the effectiveness of shear wave elastography (SWE) in patients with lower extremity superficial venous insufficiency (VI). A total of 138 symptomatic patients, 51 asymptomatic volunteers, and a total of 359 lower extremities (257 symptomatic, 102 asymptomatic) were examined. All participants underwent Doppler ultrasound (US) evaluation to determine VI and SWE measurements performed by manually drawing vein wall and perivenous tissue with free region of interest at the great saphenous vein (GSV) and small saphenous vein (SSV). The GSV, SSV diameter, VI, and volume flow of reflux were compared with the SWE va...

A Narrative Review on Contrast-Enhanced Ultrasound in Aortic Endograft Endoleak Surveillance
Endovascular repair of abdominal aortic aneurysms have been performed successfully since 1991. However, 20% to 50% of these patients may develop an endoleak or continued aneurysmal sac expansion or perfusion despite stent graft coverage. Current recommendations suggest lifelong surveillance with computed tomographic angiography (CTA) at least 1 month after intervention and yearly after that. In select patients with a stable aneurysm sac on computed tomography performed 1 year after treatment, future screening could be performed with ultrasonography. However, color Doppler ultrasound can fail to detect as many as 31% of end...
