Since its introduction, contrast‐enhanced ultrasound (CEUS) has gained an important role in the diagnosis and management of abdominal and pelvic diseases. Contrast‐enhanced ultrasound can improve lesion detection rates as well as success rates of interventional procedures when compared to conventional ultrasound alone. Additionally, CEUS enables the interventionalist to assess the dynamic enhancement of different tissues and lesions, without the adverse effects of contrast‐enhanced computed tomography, such as exposure to ionizing radiation and nephrotoxicity from iodinated contrast material. This review article describes the various applications and advantages of the use of CEUS to enhance performance of ultrasound‐guided interventions in the abdomen and pelvis. 相似文献

With the recent Food and Drug Administration approval of Lumason (sulfur hexafluoride lipid‐type A microsphere, Bracco Diagnostics Inc, Monroe Township, NJ) for contrast‐enhanced ultrasound (CEUS) to characterize focal liver lesions in both adult and pediatric patients, widespread use of CEUS is expected in the United States. This paper provides guidance in setting up a CEUS program, and reviews the practical details that will need to be instituted in a standard ultrasound department to provide both safe and efficient use of CEUS. A review of the indications, contraindications, adverse events, instructions for performing the exam, and image interpretation are discussed. 相似文献

Contrast‐Enhanced Transrectal Ultrasound for Follow‐up After Focal HIFU Ablation for Prostate Cancer
Andre L. de Castro Abreu Akbar N. Ashrafi Inderbir S. Gill Masakatsu Oishi Matthew W. Winter Daniel Park Vinay Duddalwar Mariana C. Stern Suzanne L. Palmer Manju Aron Mittul Gulati 《Journal of ultrasound in medicine》2019,38(3):811-819
The optimal strategy for imaging after focal therapy for prostate cancer is evolving. This series is an initial report on the use of contrast‐enhanced transrectal ultrasound (TRUS) in follow‐up of patients after high‐intensity focused ultrasound (HIFU) hemiablation for prostate cancer. In 7 patients who underwent HIFU hemiablation, contrast‐enhanced TRUS findings were as follows: (1) contrast‐enhanced TRUS clearly showed the HIFU ablation defect as a sharply marginated nonenhancing zone in all patients; (2) contrast‐enhanced TRUS identified suspicious foci of recurrent enhancement within the ablation zone in 2 patients, facilitating image‐guided prostate biopsy, which showed prostate cancer; and (3) contrast‐enhanced TRUS findings correlated with multiparametric magnetic resonance imaging and biopsy histologic findings. 相似文献

This case series describes a novel method for showing the preoperative anatomy of children with anorectal malformations using ultrasound contrast, which we have termed “contrast‐enhanced colosonography (ceCS).” Six patients with anorectal malformations without a perineal fistula were studied both by fluoroscopic distal colostography and ceCS, and their results were confirmed surgically. Contrast‐enhanced CS precisely showed the complex anatomic relationships in all cases. Compared to traditional fluoroscopic studies, ceCS has the benefit of no associated ionizing radiation and thus is safer for children. 相似文献

Objective. Glomerular capillary hemorrhage (GCH) has been reported and confirmed as a consequence of contrast‐enhanced diagnostic ultrasound (CEDUS) imaging of rat kidney. This study assessed renal tissue injury in the larger porcine model. Methods. The right kidneys of anesthetized pigs were imaged in 8 groups of 4 pigs. A Vingmed System Five ultrasound machine (General Electric Co, Cincinnati, OH) was used at 1.5 MHz in the B‐mode to intermittently scan the kidney at 4‐second intervals. An Acuson Sequoia 512 machine (Siemens Medical Solutions, Mountain View, CA) was used in the 1.5‐MHz Cadence contrast pulse sequencing mode with intermittent agent clearance bursts at 4‐second intervals. Kidneys were scanned transabdominally or after laparotomy through a saline standoff. The second machine's probe was placed in contact with the kidney for 1 group. A perflutren lipid microsphere contrast agent (Definity; Lantheus Medical Imaging, Inc, North Billerica, MA) was infused at 4 μL/kg/min (diluted 33:1 in saline) for 4 minutes during scanning. Results. Blood‐filled urinary tubules were evident on the kidney surface for all groups except the group with the probe in contact with the kidney. Glomerular capillary hemorrhage was found by histologic processing in 31.7% ± 9.8% (mean ± SD) of glomeruli in the center of the scan plane for 1.7‐MPa transabdominal scanning and 1.5% ± 2.9% of glomeruli in sham samples (P < .05). In addition, hematuria was detected after scanning, and tubular obstruction occurred in some nephrons. Conclusions. Renal tissue damage was induced by CEDUS in the porcine model. This result, together with previous studies in rats, support a hypothesis that GCH would occur in humans from similar CEDUS exposure. 相似文献
