| 1 | Estimation of intra-operator variability in perfusion parameter measurements using DCE-US显示文摘AIM:To investigate intra-operator variability of semiquantitative perfusion parameters using dynamic contrast-enhanced ultrasonography(DCE-US),following bolus injections of SonoVue.METHODS:The in vitro experiments were conducted using three in-house sets up based on pumping a fluid through a phantom placed in a water tank.In the in vivo experiments,B16F10 melanoma cells were xenografted to five nude mice.Both in vitro and in vivo,images were acquired following bolus injections of the ultrasound contrast agent SonoVue(Bracco,Milan,Italy) and using a Toshiba Aplio ultrasound scanner connected to a 2.9-5.8 MHz linear transducer(PZT,PLT 604AT probe)(Toshiba,Japan) allowing harmonic imaging('Vascular Recognition Imaging') involving linear raw data.A mathematical model based on the dye-dilution theory was developed by the Gustave Roussy Institute,Villejuif,France and used to evaluate seven perfusion parameters from time-intensity curves.Intra-operator variability analyses were based on determining perfusion parameter coefficients of variation(CV).RESULTS:In vitro,different volumes of SonoVue were tested with the three phantoms:intra-operator variability was found to range from 2.33% to 23.72%.In vivo,experiments were performed on tumor tissues and perfusion parameters exhibited values ranging from 1.48% to 29.97%.In addition,the area under the curve(AUC) and the area under the wash-out(AUWO) were two of the parameters of great interest since throughout in vitro and in vivo experiments their variability was lower than 15.79%.CONCLUSION:AUC and AUWO appear to be the most reliable parameters for assessing tumor perfusion using DCE-US as they exhibited the lowest CV values. | Marianne Gauthier Ingrid Leguerney Jessie Thalmensi Mohamed Chebil Sarah Parisot Pierre Peronneau Alain Roche Nathalie Lassau | 2011 | World Journal of Radiology2011，3，3： | 6 |
| 2 | Superselective embolisation of bilateral superior vesical arteries for management of intractable hematuria in context of metastatic bladder cancer显示文摘Hematuria due to locally advanced or metastatic bladder cancer is a common condition and is often a management problem.Percutaneous embolisation is a mini-invasive option to handle this situation.We report a case of a patient with a metastatic bladder cancer and who presented with an abundant hematuria and severe anemia.After failure of endoscopic resections and“flush”of radiotherapy haemostatic and refusal of cystectomy by the patient,he was treated by superselective embolisation of bilateral superior bladder arteries with excellent immediate results.The technique is safe and effective in the short term.The longterm effectiveness requires further investigation. | Ahmed Saadi Abderrazak Bouzouita Mohamed Hedi Rebai Mohamed Cherif Walid Kerkeni Haroun Ayed Amine Derouiche Hatem Rajhi Riadh Ben Slama Najla Mnif Mohamed Chebil | 2017 | Asian Journal of Urology2017，4，2： | 2 |
