Aims: A focal lesion in the region of the adrenal gland in a newborn often requires further assessment. Ultrasound (US) is the initial imaging method of choice in young children as it does not use radiation or require sedation and it has excellent spatial resolution. In this case series, we present contrast-enhanced ultrasound (CEUS) as a problem-solving tool in the evaluation of neonatal adrenal lesions.Material and methods: The imaging and medical records of five patients with adrenal lesions were retrospectively reviewed. All patients underwent US as an initial examination and all had US follow-up. Additionally, two patients had MRI examinations. CEUS was performed in all patients as a follow up examination. The enhancement characteristics of the adrenal masses on CEUS were analyzed with the use of VueBox software. In addition, qualitative analysis of the cine loops for the presence of vascularization within the lesions was performed by consensus between two radiologists.Results: The presence of an adrenal hematoma was correctly detected and characterized by CEUS in all five cases using VueBox perfusion analysis. Adrenal hematomas had no internal perfusion and flat time intensity curves.Conclusion: The quantitative and qualitative CEUS assessment of the mass can distinguish hemorrhage from a malignant lesion. Based on our findings, CEUS could serve as an alternative diagnostic tool to magnetic resonance imaging in the diagnosis of slowly resolving NAH lesions.

“…Renal CEUS was recognised as a problem-solving method in the evaluation of renal focal lesions and a promising method in microvascular renal perfusion evaluation, like in acute pyelonephritis 8 or other causes of renal perfusion disorders (in the settings of renal artery stenosis, renal infarction, including smaller and polar areas as well as cortical necrosis). 7 Most of the data regarding renal CEUS are based on studies of adults. There are only a few reports of using UCA in renal tumour or inflammation pathology in children.…”

Objective: Focal renal infections in children have to be diagnosed early in order to enable an appropriate antibiotic treatment. The purpose of this paper was to investigate the efficacy and clinical utility of intravenous renal contrast-enhanced ultrasound (CEUS) as an alternative imaging method for the diagnosis and follow-up of focal renal infections in children. Methods: Fourteen children aged from 6 months to 17 years (mean 6.5 years) in whom focal renal infection was suspected were included in this retrospective study. All data were obtained from medical and imaging records of the patients. Results: CEUS was performed for the diagnosis in all fourteen children and then also for follow-up in seven children with renal abscess. In three children enhancement pattern was concordant with focal nephritis and in four children CEUS excluded focal renal infection and the diagnosis of pseudolesion was confirmed. Conclusions: Renal CEUS was proven to be an efficient and self-sufficient imaging in diagnosis and further follow-up of focal renal infections in children. CEUS patterns of focal renal infections are described as well as relevant CEUS enhancement patterns important for differential diagnosis. Renal abscess follow-up algorithm with CEUS is suggested. Advances in knowledge: All clinically relevant imaging data was obtained by CEUS and no other imaging was necessary for the diagnosis and follow-up.

“…There are several methods for measuring kidney volumes, such as computed tomography (CT), magnetic resonance imaging (MRI), and ultrasonography (US) [ 13 ]. Even though CT and MRI provide greater accuracy than US, they have limitations for clinical use in children due to sedation and exposure to radioactivity [ 14 , 15 , 16 ]. Therefore, US is the most appropriate method for children’s studies since it is relatively reliable and noninvasive [ 16 , 17 ].…”

In this study, we aimed to develop a new automated method for kidney volume measurement in children using ultrasonography (US) with image pre-processing and hybrid learning and to formulate an equation to calculate the expected kidney volume. The volumes of 282 kidneys (141 subjects, <19 years old) with normal function and structure were measured using US. The volumes of 58 kidneys in 29 subjects who underwent US and computed tomography (CT) were determined by image segmentation and compared to those calculated by the conventional ellipsoidal method and CT using intraclass correlation coefficients (ICCs). An expected kidney volume equation was developed using multivariate regression analysis. Manual image segmentation was automated using hybrid learning to calculate the kidney volume. The ICCs for volume determined by image segmentation and ellipsoidal method were significantly different, while that for volume calculated by hybrid learning was significantly higher than that for ellipsoidal method. Volume determined by image segmentation was significantly correlated with weight, body surface area, and height. Expected kidney volume was calculated as (2.22 × weight (kg) + 0.252 × height (cm) + 5.138). This method will be valuable in establishing an age-matched normal kidney growth chart through the accumulation and analysis of large-scale data.
