Breaking barriers: The impact of telemedicine on improving soft tissue and bone tumor management in Armenia.

Purpose: Musculoskeletal sarcomas are a rare group of malignant neoplasms, accounting for approximately 12 % of all malignant neoplasms among children. Childhood cancer outcomes vary between developed and developing countries due to financial and educational inequalities. Telemedicine programs have a huge impact on the quality of cancer care, helping to optimize resources for better cancer care in a resource-limited setting.

Lung ultrasound in children and adolescents with long-term effects of COVID-19: Initial results.

Introduction: Chronic health effects following acute COVID-19 are increasingly observed as the pandemic continues and are grouped under long COVID. Although the acute course of the COVID disease is often milder, long COVID also affects children and adolescents. As the symptoms present in Long-COVID often seem to be non-specific and not limited to organ systems, clarification of the causes and the creation of a meaningful, efficient and targeted diagnostic algorithm is urgently needed.

Whole-body diffusion magnetic resonance imaging with simultaneous multi-slice excitation in children and adolescents.

Background: Whole-body magnetic resonance imaging (WB-MRI) is an increasingly used guideline-based imaging modality for oncological and non-oncological pathologies during childhood and adolescence. While diffusion-weighted imaging (DWI), a part of WB-MRI, enhances image interpretation and improves sensitivity, it also requires the longest acquisition time during a typical WB-MRI scan protocol. Interleaved short tau inversion recovery (STIR) DWI with simultaneous multi-slice (SMS) acquisition is an effective way to speed up examinations.

Differences in Cerebellar Volume as a Diagnostic and Prognostic Biomarker in Children and Adolescents With Epilepsy of Unknown Etiology.

Introduction And Objective: Epilepsy is one of the most common brain diseases during childhood and adolescence. Atrophy in different brain areas is possible during epilepsy. This study aimed to verify whether cerebellar volume differences could be detected by volume analysis using magnetic resonance imaging (MRI) in children with epilepsy.

[Tuberous sclerosis complex].

Clinical Background: Tuberous sclerosis complex (TSC) is a phakomatosis and is a tumor predisposition syndrome. As a genetic multisystem disease, patients present with a broad range of changes in the brain, heart, skin, kidneys, and lungs.

Objectives: Which imaging modalities are required to monitor TSC patients according to current international recommendations?

Materials And Methods: Common findings in TSC are cortical tubers, subependymal nodules, and giant cell astrocytomas in the central nervous system (CNS), rhabdomyomas in the heart, and cysts and angiomyolipomas in the kidneys.

A novel free-breathing abdominal RAVE T/T hybrid MRI sequence in patients with cystic fibrosis: Preliminary results.

Objectives: Patients with cystic fibrosis (CF) increasingly require imaging for the diagnosis of abdominal complications. We prospectively evaluated the image quality and signal-to-noise ratio (SNR) of a modern radial volumetric encoding (RAVE) T/T hybrid sequence for abdominal magnetic resonance imaging (MRI). RAVET/T is a three-dimensional radial sequence with fat saturation and blood flow suppression that acquires T- and T-weighted contrasts in one scan in an identical slice position during free-breathing.

Ultrasound elastography in children - nice to have for scientific studies or arrived in clinical routine?

Ultrasound elastography (USE) is a modality that in addition to fundamental B-mode, Doppler, and contrast-enhanced sonography is suitable to make qualitative and quantitative statements about the stiffness of tissues. Introduced more than 20 years ago in adults, USE becomes now a diagnostic tool also in children. The aim of this paper is to describe current available techniques for USE in children.

Preliminary results of abdominal simultaneous multi-slice accelerated diffusion-weighted imaging with motion-correction in patients with cystic fibrosis and impaired compliance.

Objectives: The aim of this prospective study was to compare scan time, image quality, signal-to-noise Ratio (SNR), and apparent diffusion coefficient (ADC) values of simultaneous multi-slice accelerated diffusion-weighted imaging with motion-correction (DWI SMS Moco) to standard diffusion-weighted imaging (sDWI) in free-breathing abdominal magnetic resonance imaging (MRI) in pediatric and young adult patients with cystic fibrosis (CF).

Material And Methods: 16 patients (7 male and 9 female, 12-41 years old) with CF were examined prospectively in a single-center from November 2020 to March 2021 on a 1.5 Tesla clinical MR scanner.

Evaluation of the post-processing algorithms SimGrid and S-Enhance for paediatric intensive care patients and neonates.

Background: Post-processing software can be used in digital radiography to achieve higher image quality, especially in cases of scattered radiation. SimGrid is a grid-like software based on a Convolutional Neuronal Network that estimates the distribution and degree of scattered radiation in radiographs and thus improves image quality by simulating an anti-scatter grid. S-Enhance is an algorithm programmed to improve contrast visibility of foreign material.

Case Report: Report of 2 Different Cases of Ovarian Teratoma Evaluated by Dynamic Contrast-Enhanced Ultrasound.

Ovarian masses are not easily differentiated on transabdominal ultrasound in children. A useful supplement in various pediatric applications is dynamic contrast-enhanced ultrasound (dynCEUS). It can be performed quickly and easily.

[Top ten pediatric radiological emergencies].

Pediatric emergencies encompass a wide range of different findings. These include injuries to the child's body due to high-energy trauma or abuse, unclear limitations of consciousness and primarily unspecific abdominal or thoracic pain as well as swallowing or inhalation of foreign bodies. Detailed knowledge of the various imaging methods and the correct application are important.

Safety of gadobutrol: results of a non-interventional study of 3710 patients, including 404 children.

Background: The safety of gadolinium-based contrast agents is a hot topic in radiology.

Purpose: To evaluate the safety profile of gadobutrol during routine use.

Material And Methods: Prospective, non-interventional study in 80 centers in Germany.

Safety of gadobutrol in more than 1,000 pediatric patients: subanalysis of the GARDIAN study, a global multicenter prospective non-interventional study.

Background: Gadobutrol is a gadolinium-based contrast agent, uniquely formulated at 1.0 mmol/ml. Although there is extensive safety evidence on the use of gadobutrol in adults, few studies have addressed the safety and tolerability of gadobutrol in pediatric patients.

Bridging bronchus--a rare cause of recurrent wheezy bronchitis.

Background: Wheezing is a common symptom in infants and toddlers. Usually it occurs due to viral infection of the lower airways and no further diagnostic procedures are necessary. However in rare cases, other reasons such as anatomical malformation have to be considered.

Pharmacokinetics and safety of gadobutrol-enhanced magnetic resonance imaging in pediatric patients.

Objectives: This clinical study investigated the pharmacokinetics and safety of gadobutrol, a magnetic resonance (MR) imaging extracellular contrast agent, in pediatric patients aged 2 to 17 years.

Materials And Methods: In this open-label, multicenter study, patients scheduled for routine contrast-enhanced MR imaging of the brain, spine, liver or kidney, or MR angiography received a single intravenous injection of gadobutrol (0.1 mmol/kg/0.

Inner border--a specific and significant colposcopic sign for moderate or severe dysplasia (cervical intraepithelial neoplasia 2 or 3).

Objective: Investigation of the correlation between the colposcopic sign inner border and cervical intraepithelial neoplasia (CIN) 2 or 3 and its association with specific human papillomavirus (HPV) types and the age of the patient.

Study Design: Colpophotographs or cervicograms were taken from 947 women referred due to an abnormal cervical finding. Occurrence of the colposcopic sign inner border was evaluated retrospectively by 2 independent colposcopists.
