Abstract

Purpose

Contrast-enhanced ultrasound (CEUS) is the application of ultrasound contrast agents (UCAs) to traditional medical sonography. The development of UCAs allowed to overcome some of the limitations of conventional B-mode and Doppler ultrasound techniques and enabled the display of the parenchymal microvasculature. Purpose of this paper is to delineate the elements of a solid and science-based technique in the execution of urinary bladder CEUS.

Methods

We describe the technical execution of urinary bladder CEUS and the use of perfusion softwares to perform contrast enhancement quantitative analysis with generation of time–intensity curves from regions of interest.

Results

During CEUS, normal bladder wall shows a wash-in time of 13 s, a time to peak (TTP) >40 s, a signal intensity (SI) <45 % and a wash-out time >80 s; Low-grade urothelial cell carcinoma (UCC) shows a wash-in time of 13 s, a time to peak TTP >28 s, a SI <45 % and a wash-out time of 40 s; High-grade UCC shows a wash-in time of 13 s, a TTP >28 s, a SI >50 % and a wash-out time of 58 s.

Conclusions

CEUS is a useful tool for an accurate characterization of bladder UCC although it has some drawbacks. To avoid misunderstandings, a widely accepted classification and a standardized terminology about the most significant parameters of this application should be adopted in the immediate future.

Riassunto

Obiettivi

l'ecografia con mezzo di contrasto (CEUS) è l'ecografia medica tradizionale con l'utilizzo di mezzi di contrasto ecografici (MDCe). Lo sviluppo di MDCe ha consentito di superare alcune delle limitazioni dell'ecografia B-mode e Doppler convenzionali ed ha consentito la visualizzazione del microcircolo parenchimale. Scopo di questo lavoro è quello di delineare gli elementi di una tecnica solida e basata sull'evidenza scientifica per l'esecuzione della CEUS della vescica urinaria.

Materiali e Metodi

Descriviamo l'esecuzione tecnica della CEUS della vescica urinaria e l'utilizzo di software di perfusione per l’esecuzione dell'analisi quantitativa dell’enhancement contrastografico con la generazione di curve intensità tempo (TIC) delle regioni di interesse (ROI).

Risultati

Durante la CEUS, la parete della vescica normale mostra un tempo di wash-in di 13 sec., un tempo di picco (TTP) >40sec., una intensità di segnale (SI) <45% e un tempo di wash-out >80 sec.; il carcinoma uroteliale (CU) di basso grado mostra un tempo di wash-in di 13 sec., un tempo di picco (TTP) >28sec., un’intensità di segnale (SI) <45% e un tempo wash-out di 40 sec.; il CU di alto grado mostra un tempo di wash-in di 13 sec., un tempo di picco (TTP) >28sec., un’intensità di segnale (SI) >50% e un tempo di wash-out di 58 sec.

Conclusioni

La CEUS è uno strumento utile per una caratterizzazione accurata del CU della vescica anche se possiede alcuni svantaggi. Al fine di evitare incomprensioni, dovrebbero essere adottate in futuro, una classificazione largamente accettata e una terminologia standardizzata sui parametri più significativi di questa applicazione.
