Pediatric lumbar puncture can be challenging or unsuccessful for several reasons. At the same time, the excellent sonographic window into the pediatric spine provides a distinct opportunity for ultrasound-guided lumbar puncture. Minimal cerebrospinal fluid and thecal displacement by subdural or epidural hematomas are common after failed clinical attempts. Ultrasound is useful for determining a safe infraconal level for subarachnoid access. Real-time guidance increases not only the success rate but also the safety of diagnostic lumbar puncture and injections for chemotherapy and myelography...

BACKGROUND: Diagnosing intestinal strangulation as a complication of small bowel obstruction (SBO) remains a considerable challenge in children. We evaluated the clinicoradiological parameters for predicting the presence of a strangulated intestine. METHODS: We reviewed the medical records of 69 pediatric patients who underwent operation for acute SBO. Regression analysis was used to identify the parameters for predicting strangulated SBO. RESULTS: Of the 69 patients with SBO, 27 patients had intestinal strangulation and were awarded one point each towards the overall clinical score: intractable continuous abdominal pain, tachycardia, white blood cell count >13,600/mm(3), and abdominal distention...

OBJECTIVES: Computed tomography (CT) has been widely used in the evaluation of children with suspected appendicitis, but concerns about ionizing radiation have increased interest in ultrasound for these patients. We sought to assess the effectiveness of an appendicitis electronic clinical decision support (E-CDS) system in increasing ultrasound and decreasing CT use in children evaluated in emergency departments (EDs) for suspected appendicitis. METHODS: This was a preintervention and postintervention analysis of an E-CDS implemented into an electronic health record system shared by an academic, tertiary-care children's hospital and a community hospital...

Pediatric Pneumonia is one of the principal causes of death by year on children under the age of five worldwide. The diagnosis is commonly made by clinical criteria with support from imaging tools like radiography. Lung ultrasound has been considered a low-cost and portable alternative for pneumonia imaging; however, interpretation is subjective and requires adequate training. In the present work, a pneumonia detection algorithm based on the measurement of the fundamental bandwidth downshift over depth of ultrasound radiofrequency (RF) signals is presented...

Non-parasitic splenic cysts (NPSC) are a rare condition that makes difficult to know their true incidence and represent 10% of all benign splenic cysts, they can be either congenital with the presence of epithelial lining that originate from invagination of the capsular mesothelial lining or post-traumatic with absence of epithelial lining. We present our management of a splenic congenital cyst in a pediatric patient. A 10-year-old female patient presented to the clinic complaining with a 3-week abdominal pain at the left upper quadrant...

Image-guided biopsy techniques are widely used in clinical practice. Commonly used methods employ either ultrasound (US) or computed tomography (CT) for image guidance. In certain patients, US or CT guidance may be suboptimal, or even impossible, because of artifacts, suboptimal lesion visualization, or both. We recently began performing magnetic resonance (MR)-guided biopsy of focal liver lesions in select pediatric patients with lesions that are not well visualized by US or CT. This report describes our experience performing MR-guided biopsy of focal liver lesions, with case examples to illustrate innovative techniques and novel aspects of these procedures...

BACKGROUND: Pharmacologic prophylaxis for venous thromboembolism (VTE) is a widely accepted practice in adult trauma patients to prevent associated morbidity and mortality. However, VTE prophylaxis has not been standardized in injured pediatric patients. Our institution identified factors potentially associated with a high risk of VTE in critically injured children that led to prospective implementation of VTE prophylaxis guidelines. We hypothesize the guidelines are accurate in predicting children at risk for VTE...

REVIEW
Nicolaj Grønbæk Laugesen, Christian Pallson Nolsoe, Jacob Rosenberg
In pediatrics ultrasound has long been viewed more favorably than imaging that exposes patients to radiation and iodinated contrast or requires sedation. It is child-friendly and diagnostic capabilities have been improved with the advent of contrast-enhanced ultrasound (CEUS). The application of CEUS is indeed promising. However, no ultrasound contrast agent manufactured today is registered for pediatric use in Europe. The contrast agent SonoVue(®) has recently been approved by the FDA under the name of Lumason(®) to be used in hepatic investigations in adults and children...

Conjoined twins are a rare, but serious, complication of monozygotic twins. Early prenatal diagnosis of conjoined twins is increasingly made with transvaginal ultrasound and color Doppler studies. Most prenatally diagnosed conjoined twins are terminated due to the high perinatal mortality, but advancement in pediatric surgery has allowed for successful postnatal separation in a small number of cases, and some parents may consider this option over termination of pregnancy. It is important to get a detailed prenatal ultrasound for the site and extent of fusion for an accurate categorization...

Renal lymphangiomatosis is a rare, benign malformation, characterized by developmental malformation of the perirenal, peripelvic, and intrarenal lymphatics. Radiologist knowledge of the unique radiological features of this entity helps patient's safety in terms of management. We study the case of a 27-month-old boy presented to the emergency department with upper respiratory tract infection. He had a high blood pressure and had been diagnosed earlier with autosomal recessive polycystic kidney disease based on renal ultrasound findings...

BACKGROUND: Minimizing the ionizing radiation dose to children is fundamental to pediatric radiology. The most widely accepted imaging examination for evaluating craniosynostosis is computed tomography (CT) of the head, an examination that involves ionizing radiation. OBJECTIVE: To determine if sonography of the cranial sutures is an adequate screening examination for the diagnosis of craniosynostosis in patients with abnormal skull shape. MATERIALS AND METHODS: A retrospective review of all cranial suture ultrasound (US) examinations performed during the course of a 3-year period (July 2012 - September 2015) was undertaken...

BACKGROUND: While ultrasound (US), given its lack of ionizing radiation is currently the recommended initial imaging study of choice for the diagnosis of appendicitis in pediatric and young adult patients, it does have significant shortcomings. US is time intensive, operator dependent, and results in frequent inconclusive studies, thus necessitating further imaging, and admission for observation or repeat clinical visits. A rapid focused Magnetic Resonance Imaging (MRI) for appendicitis has been shown to have definitive sensitivity and specificity, similar to Computed tomography (CT) but without radiation and offers a potential alternative to US...
