Intrarenal Reflux in the Light of Contrast-Enhanced Voiding Urosonography.

Front Pediatr 2021 2;9:642077. Epub 2021 Mar 2.

University Hospital Split, Split, Croatia.

The aim of this study was to analyze the incidence of intrarenal reflux (IRR) among vesicoureteral refluxes (VURs), diagnosed by contrast-enhanced voiding urosonography (ceVUS), to define VURs which are positive to IRR and their locations in the kidney. Seventy patients with VURs, including 103 uretero-renal units (URUs) with VURs of grades II-V (37 URUs were excluded because of renal anomalies or absence of VUR) were examined with ceVUS due to recurrent febrile UTI or first febrile UTI accompanied by abnormalities on renal ultrasonography. Patients were examined on GE Logiq S8 ultrasound machine, using second generation of ultrasound contrast agent. Read More

Contrast-enhanced voiding urosonography in the diagnosis of intrarenal reflux.

J Ultrasound 2021 Feb 26. Epub 2021 Feb 26.

Children's Hospital Zagreb, Ul. Vjekoslava Klaića 16, 10000, Zagreb, Croatia.

Purpose: Although contrast-enhanced urosonography (ceVUS) has shown capable diagnostic accuracy for the diagnosis of vesicoureteral reflux (VUR) in children, the ability of ceVUS to detect intrarenal reflux (IRR) is considered limited. The purpose of our study is to assess the ability of ceVUS to detect IRR as well as its association with age, gender, and the grade of VUR.

Methods: This study included 5153 children who were referred to our clinic for ceVUS. Read More

In vivo feasibility of real-time MR-US fusion imaging lumbar facet joint injections.

J Ultrasound 2017 Mar 12;20(1):23-31. Epub 2017 Jan 12.

S.C. Diagnostica per Immagini, Radiologia, Ospedale Evangelico Internazionale, Corso Solferino 2A, 16100 Genoa, Italy.

Objectives: Traditionally, facet joint injections (FJI) are performed under fluoroscopic or computed tomography (CT) guidance, mainly due to the deep anatomical location and the presence of bony landmarks. Fusion imaging technology, which couples the ultrasound scan with the corresponding CT or magnetic resonance (MR) image obtained from the diagnostic examination and reformatted in real time according to the ultrasound scanning plane, allows to combine the panoramic view and the elevated anatomical detail of MR or CT with the ease of use of ultrasound without patient exposure to ionizing radiation.

Methods: Thirty eight patients (24 females; mean age ± SD: 64 ± 9 years) received MR fusion-assisted ultrasound-guided FJI of 1 ml of a mixture of local anaesthetic and corticosteroid using a ultrasound machine (Logiq E9, GE Healthcare) equipped with a GPS-enhanced fusion imaging technology which couples real-time B-mode images with those of the previous recent diagnostic MR examination.
