Abstract:

Introduction: Renal calculus is a solid mass of crystals that may block the urinary tract. Calcium and oxalate combine to create the majority of these crystals. These kidney stones pass via the urinary system to leave the body. Most stones may not certainly cause any symptoms or signs until they start moving toward the ureter. For detecting kidney stones twinkling artifact in Color Doppler Ultrasonography (CDU) is a useful sensitive instrument. The twinkling artifact's effect is highly dependent on machine settings and is probably created by phase (or clock) jitter. When illuminating specific

Abstract:

<strong>Background</strong>: The characterization of renal and ureteric calculi composition has been explored using various imaging techniques. The study aimed to assess the correlation of ultrasound twinkling artifacts with Dual Energy Computed Tomography (DECT) in this context.   <strong>Aims and Objectives: </strong>Establish the association between the composition of renal stones and the presence and grading of twinkling artifacts using color Doppler, in comparison with Dual Energy CT. Determine the sensitivity and specificity of ultrasound twinkling artifact vis-à-vis Dual Ene

Research goal: evaluation of the possibility of using an ultrasound twinkling artifact in the detection of breast calcifications as a diagnostic criterion for breast cancer.Material and methods. A targeted ultrasound study using color Doppler mapping was performed to determine the presence of a twinkling artifact in 112 patients who had calcifications detected during X-ray mammography.Results. According to the ultrasound examination, the twinkling artifact was registered only in 10 of the 112 women examined. A pronounced twinkling artifact was registered in 3 patients, the calcifications were

Abstract:

Aims: Ultrasound is a noninvasive method used for the diagnosis of urinary lithiasis. When the length of the stone is less than 5 mm, its detection may be difficult. The twinkling artifact (TwA) is an intense alternating color signal behind calcifications and stones in different organs. The aim of this paper was to evaluate the importance of the TwA in detecting kidney stones less than 5 mm in length. Material and methods: We examined 230 patients with lumbar pain or a history of kidney stones. We excluded patients with stones larger than 5 mm. 174 patients corresponded to the inclusion criter

Abstract:

Background: Nephrolithiasis, or kidney stones, is a prevalent condition that prompts numerous patient visits to emergency departments worldwide. The diagnosis of this condition and its complications, such as hydronephrosis, has traditionally relied on various imaging modalities, with ultrasound being a primary, non-invasive option. Recent advancements, including the utilization of the color Doppler twinkling artifact, have potentially enhanced the diagnostic capabilities of ultrasound for nephrolithiasis. Objective: This study aims to evaluate the effectiveness of B-mode sonography and the col

Abstract:

Imaging crystalline structures with Doppler ultrasound can produce a rapid color shift, termed the twinkling artifact, that can assist in diagnosing pathological mineralizations such as kidney stones, heterotopic ossification, gout, and breast microcalcifications. Twinkling is theorized to arise from scattering off surface crevice microbubbles, which are affected by the surface tension between the bubble and surrounding medium. In this study, we evaluated the effect of surface tension on twinkling in pure crystals. Cholesterol, calcium phosphate, and uric acid crystals were grown in vitro (n =

Abstract:

The twinkling artifact, or twinkling, appears when imaging kidney stones and other mineralizations with Doppler ultrasound and is caused by scattering off crevice microbubbles. Previous work found that twinkling on in vivo kidney stones increased or decreased with elevated oxygen or carbon dioxide, respectively. However, it is unclear whether these results are from biological adaptions to the changing respiratory gas and thus if in vitro mineralizations are similarly affected. Here, cholesterol, calcium phosphate, and uric acid crystals were grown in vitro and imaged in deionized water using a

Abstract:

The twinkling artifact, or rapid color shifts, are observed when imaging kidney stones and other mineralizations. The current theory is that scattering from bubbles in micron-sized crevices causes twinkling. Our objective is to investigate the effect of ultrasound frequency and crevice size and number on twinkling of silicon wafers. Ten or 100 randomly positioned cylindrical crevices with diameters of 1, 10, or 100 μm and depths of 10 μm were dry-etched on wafers. A research ultrasound system was used to image wafers at 5, 7.8, and 18.5 MHz; IQ data were post-processed to calculate twinkling o
