Incidental Findings on Brain Magnetic Resonance Imaging (MRI) in Pediatric Endocrine Patients.

Objective: To explore incidental findings on brain magnetic resonance imaging (MRI) studies of pediatric patients referred due to endocrine disorders.

Methods: A retrospective, observational study conducted in a tertiary referral center. The neuroimaging database of 17,445 brain MRI studies of 11,011 pediatric patients were searched for cases with endocrine referrals and without medical history of malignancy, genetic syndromes, and/or neurologic comorbidities.

Brain white matter abnormalities associated with copy number variants.

White matter (WM) signal abnormalities are demonstrated in various neurodevelopmental disorders on brain magnetic resonance imaging (MRI). The pattern of WM abnormalities can aid in the diagnostic process. This study aims to characterize the WM changes found in microdeletion/microduplication syndromes.

Mature teratoma splitting the brainstem in a newborn: case report.

Mature teratomas (MTs) of the posterior fossa are extremely rare. The authors present a case of a prenatal diagnosis of an MT splitting the brainstem. Representative images as well as the clinical and surgical course are presented.

Use of EOS Low-Dose Biplanar X-Ray for Shunt Series in Children with Hydrocephalus: A Preliminary Study.

Introduction: Shunt series (SS) are a common diagnostic tool used to verify shunt integrity. SS include X-ray films of the skull, chest, and abdomen and often are performed either when a shunted patient presents with suspected shunt malfunction or as a screening test to identify shunt disconnections or dislodgment. EOS low-dose biplanar X-rays are associated with significantly reduced radiation doses compared with ordinary X-rays and are used for various indications.

Radiologists' performance in the diagnosis of acute intestinal ischemia, using MDCT and specific CT findings, using a variety of CT protocols.

The aim of this study was to evaluate the performance of radiologists in the diagnosis of acute intestinal ischemia using specific multi-detector CT findings. The abdominal CT scans of 90 patients were retrospectively reviewed by three radiologists: an abdominal imaging specialist, an experienced general radiologist, and a senior resident. Forty-seven patients had surgically proven intestinal ischemia and comprised the case group, while 43 patients had no evidence of intestinal ischemia at surgery and comprised the control group.

Automatic segmentation and components classification of optic pathway gliomas in MRI.

We present a new method for the automatic segmentation and components classification of brain Optic Pathway Gliomas (OPGs) from multi-spectral MRI datasets. Our method accurately identifies the sharp OPG boundaries and consistently delineates the missing contours by effectively incorporating prior location, shape, and intensity information. It then classifies the segmented OPG volume into its three main components--solid, enhancing, and cyst--with a probabilistic tumor tissue model generated from training datasets that accounts for the datasets grey-level differences.
