Image quality and radiation doses of volumetric 320-row computed tomography angiography with prospective electrocardiogram-gating in the assessment of coronary arteries in neonates and infants.

Background: Diagnostic imaging of coronary arteries is required in neonates and infants suspected of congenital or acquired coronary artery anomalies and in pre- and postoperative assessment of complex congenital heart diseases (CHD).

Aim: Our study aimed to evaluate the image quality of volumetric 320-row computed tomography angiography (CTA) with prospective electrocardiogram (ECG)-gating for coronary arteries in neonates and infants with heart diseases, analyze factors influencing image quality and assess a radiation dose related to the procedure.

Methods: The study included 110 CTA performed in neonates and infants with CHD.

Normal values of native T and T relaxation times on 3T cardiac MR in a healthy pediatric population aged 9-18 years.

Background: Native myocardial T and T relaxation times are diagnostic tools used in clinical practice for adult and pediatric populations. Use of a mapping technique requires accurate knowledge of normal ranges in healthy patients, which is lacking in pediatric populations.

Purpose: To establish normal values for native T and T mapping in healthy pediatric subjects of different ages and sex.

Cardiovascular magnetic resonance with parametric mapping in long-term ultra-marathon runners.

Purpose: There is a direct reverse dose-effect relationship between the amount of physical activity and cardiovascular risk. It is unknown whether this is true for extreme, persistent endurance training. The aim of the study was to assess structural changes of the heart in long-time ultra-marathon runners with special focus on myocardial fibrosis using parametric mapping.

Late diagnosis of total anomalous pulmonary venous drainage in a 5.5-month-old infant.

A 5.5-month-old girl was admitted with non-specific signs and symptoms like dyspnea at rest, tachypnea, fatigue, low body weight and cyanosis on exertion. Physical examination revealed a barrel-shaped chest; no pathological sounds over the heart or both lung areas were detected.

Nijmegen Breakage Syndrome Complicated With Primary Pulmonary Granulomas.

Nijmegen breakage syndrome (NBS) is a rare autosomal recessive disease characterized by microcephaly, growth retardation, severe immunodeficiency, and predisposition to lymphoid malignancy. In this report, we describe a case of a 9-year-old boy, previously diagnosed with NBS and symptoms of dyspnea, dry cough, and fever. Despite initial recognition of pneumonia, there was no response to broad spectrum antimicrobial treatment, negative results from microbiological tests, and unclear changes in lung imaging were observed.

Postnatal Evaluation of Congenital Chest Pathologies Using a Low-Dose Computed Tomography (CT) Protocol - a Pictorial Review.

Computed tomography with its excellent spatial and temporal resolution remains a valuable diagnostic modality in pediatrics. On the other hand an increasing attention has been placed on the radiation risks associated with CT imaging, especially in children. In recent years, many advances in CT hardware and software, for example, automatic exposure control tools and iterative reconstruction techniques, have allowed for a reduction of applied radiation doses while maintaining image quality.

Laparoscopic splenectomy for hereditary spherocytosis-preliminary report.

Splenectomy is considered standard surgical therapy in hereditary spherocytosis. The procedure is indicated in patients with severe anemia, recurrent hemolytic, and aplastic crises. The aim of the study was to assess treatment outcomes in patients with hereditary spherocytosis who underwent total or partial laparoscopic splenectomy.

Atypical imaging features of adrenal gland lesions in children - report of three cases and review of literature.

Background: The differential diagnosis of adrenal pathology depends on the child's age and imaging findings.

Case Report: Three children without clinical symptoms of neoplasm, with an adrenal lesion discovered on diagnostic ultrasound imaging. Laboratory tests for neoplasm were negative.

An unusual oesophageal foreign body in neonate - case report.

Background: Foreign bodies in the esophagus in children are usually swallowed accidentally during play. An oesophageal foreign body in neonate is rare and thus the diagnostic work-up may be difficult.

Case Report: We present a case of an 8-day-old baby with symptoms of oesophageal obstruction.

Abscess mimicking lung metastasis in a 10-year-old boy - case report.

Background: Malignant pulmonary tumours in children are very rare; the majority are metastases. Nonspecific radiographic findings of these abnormalities are challenging and may delay the final diagnosis and treatment.

Case Report: A 10-year-old boy was admitted to our hospital because of the clinical and radiographic symptoms and signs of pneumonia with abscess formation in the left lower lobe.
