“…Anechoic analysis is performed by scanning the phantom and freezing (choosing) the image, making measurement, and recording anechoic visualization composed by measuring diameter of each anechoic circle vertically and horizontally of the phantom. In order to find out the percentage of axial and lateral accuracy of measurement results, comparisons can be made between distance from those results and actual distances as stated in the phantom CIRS 054GS book manual [11].…”

The use of polymer as conductor in medical ultrasonography is very crucial to establish patient diagnosis and to prevent administration of improper treatment. Rapid development in science and technology encourages people to create more innovations that are readily usable. However, these innovations sometimes put health and environmental aspects aside that in turn become disadvantageous to health and may lead to environmental pollution. This research proposes the use of carrageenan biopolymer as a safe alternative for people’s health and the environment. It aims to prove differences in resulting phantom CIRS images taken with the help of carrageenan gel and standard gel based on Carbomer 940 as acoustic coupling agents (ACA) for ultrasonography (USG). It is an experimental research that uses true experiment technique with posttest only control group design. Results from T-test analysis show significance value of p>0.05, meaning there is no significant difference between the use of carrageenan gel and ACA gel (Carbomer 940). This result proves that carrageenan gel can be used as an acoustic coupling agent for ultrasonography. Results from imaging tests also reveal that there is no difference between the use of carrageenan gel and that of a manufacturer gel based on Carbomer 940 available in Indonesia, in terms of visualization of phantom CIRS images.

“…Additionally, contrast-enhanced US (CEUS) refers to the application of US contrast agents in medical US. CEUS can provide anatomic information with gray-scale US and physiologic information through the SDUS, CDUS, and PDUS techniques, making it indispensable in the assessment of vascular pathology [15][16][17][18][19][20][21]. The presence of a microbubble US contrast agent in the vasculature enhances the backscattering of US waves, resulting in a marked amplification of flow signals and providing information on the microvasculature [12,21,22].…”

Clinical applications of Doppler ultrasonography for thyroid disease: consensus statement by the Korean Society of Thyroid Radiology

et al. 2020

Doppler ultrasonography (US) is widely used for the differential diagnosis of thyroid nodules, metastatic cervical lymph nodes in patients with thyroid cancer, and diffuse parenchymal disease, as well as for guidance in various US-guided procedures, including biopsy and ablation. However, controversies remain regarding the appropriate use and interpretation of Doppler US. Therefore, the Korean Society of Thyroid Radiology organized a taskforce to develop a consensus statement on the clinical use of Doppler US for thyroid disease. The review and recommendations in this article are based on a comprehensive analysis of the current literature and the consensus of experts.

“…A higher mechanical index (MI) applied also results in earlier disruption of microbubbles. A higher dose of 4.8 ml of the UCA should be used for achieving optimal enhancement of testicular parenchyma [9,22].…”

“…A rare consequence of penetrating testicular trauma is a pseudoaneurysm which appears as an anechoic region on B-mode imaging. On CDUS and spectral Doppler US interrogation, oscillating spectral Doppler ("ying yang" appearance on CDUS) is typical of a pseudoaneurysm [23] and can also be seen on CEUS [22].…”

The role of contrast-enhanced ultrasound (CEUS) in the evaluation of scrotal trauma: a review

Testicular trauma is common, usually trivial and rarely requires hospital attendance, but if it does, then imaging becomes essential as scrotal assessment may be difficult due to pain and/or scrotal disruption. Ultrasound (US) assumes a crucial role as other cross-sectional modalities have a limited use in the acute presentation. Despite the acceptable accuracy of conventional US techniques, there are limitations which hinder a thorough evaluation, critically the assessment of tissue viability, crucial for clinical management and prognosis. Contrast-enhanced ultrasound (CEUS) has been shown to offer improved flow visualisation and tissue perfusion compared with conventional Doppler techniques. CEUS can accurately and confidently demonstrate the viability of testicular parenchyma, delineate fracture lines and haematomas and guide treatment for testis-sparing surgery or orchidectomy. The purpose of this review is to present the literature, familiarise physicians with the principles of CEUS and findings of scrotal trauma and illustrate the main abnormalities through characteristic and educative cases.
