Anal agenesis with recto-bulbar fistula
Pediatric Radiology - Tập 16 - Trang 222-224 - 1986
Four cases of anal agenesis with rectobulbar fistula, a rare type of anorectal anomaly, are described along with the preferred mode of radiological investigation to demonstrate the fistula.
MR imaging differentiation of benign and malignant peripheral nerve sheath tumors: use of the target sign
Pediatric Radiology - Tập 27 - Trang 124-129 - 1997
T2-weighted MR imaging of soft tissue tumors of neural origin may show round lesions with a central hypointensity and a hyperintense rim resembling a target. We define the “target sign” as a mass consisting of a solitary target, or a multicompartmental mass in which the largest component consists of multiple targets. The objective of this study was to determine whether the target sign can differen......
High-pitch CT, decreasing need for sedation and its potential side effects: some practical considerations and future directions

Intestinal blood-flow velocity in uncomplicated preterm infants during the early neonatal period
Pediatric Radiology - Tập 29 Số 6 - Trang 472-477 - 1999
Background. Intestinal blood-flow changes after birth. Objective. To elucidate the factors influencing intestinal blood-flow velocity in preterm infants during the early neonatal period. Materials and methods. We measured blood-flow velocity in the superior mesenteric artery by pulsed Doppler US in 44 uncomplicated infants with a gestational age of less than 34 weeks and from 1 to 6 days of age. R......
Inflammatory pseudotumor of the lung manifesting as a posterior mediastinal mass
Pediatric Radiology - Tập 22 - Trang 467-468 - 1992
A case of inflammatory pseudotumor of the lung in a 6-year-old boy is presented. The respiratory illness presented as a mycoplasma pneumonia and there had been a similar episode of mycoplasma pneumonia one and a half years previously. Computed tomography revealed a large, calcified right posterior mediastinal mass and exploratory thoracotomy revealed a large posterior mediastinal mass that had an ......
Placental magnetic resonance imaging Part I: the normal placenta
Pediatric Radiology - Tập 50 - Trang 264-274 - 2020
Mounting evidence suggests that the placenta is involved in nearly all abnormalities of pregnancy and fetal development. Traditional imaging evaluation of the placenta by ultrasound has more recently been complemented by MRI for complex cases requiring additional information, such as in the diagnosis of the placenta accreta spectrum (placenta accreta, increta and percreta). MRI can often help deli......
Pulmonary aspergillosis and pseudosequestration of the lung in chronic granulomatous disease
Pediatric Radiology - Tập 25 - Trang 201-203 - 1995
We present a case of chronic granulomatous disease with an angiographically proven pseudo-sequestration of the lung. The patient was a 15-year-old boy who was admitted to the hospital with symptoms of fever, cough, hemoptysis and a subcutaneous abscess.Aspergillus fumigatus was isolated from the sputum and the abscess. During treatment, angiography demonstrated on anomalous blood supply to the rig......
Pediatric CT radiation exposure: where we were, and where we are now
Pediatric Radiology - Tập 49 - Trang 469-478 - 2019
Since the turn of the last millennium, the pediatric radiology community has blazed a patient-quality and safety trail in helping to effectively address the public and the news media’s concerns about the implications of ionizing radiation from CT scanners in children. As such, this article (1) reviews the potential deleterious effects of ionizing radiation, (2) discusses why limiting radiation exp......
Low-field 0.55 T MRI evaluation of the fetusAbstract
Fetal magnetic resonance imaging (MRI) is an important adjunct modality for the evaluation of fetal abnormalities. Recently, low-field MRI systems at 0.55 Tesla have become available which can produce images on par with 1.5 Tesla systems but with lower power deposition, acoustic noise, and artifact. In this article, we describe a technical innovation using... ...
