ReviewUnderutilized ultrasound applications in the neonatal intensive care unit.
Bedside duplex/color Doppler sonography is used for a wide gamut of abnormalities encountered in the neonatal intensive care unit. This article emphasizes the use of bedside sonography for evaluation of infants with necrotizing enterocolitis, infants requiring line placement, and those in whom a diaphragmatic abnormality is suspected. Although the assessment of those infants requires excellent operator skills, learning to do so is a definite benefit to these babies who would otherwise be exposed to ionizing radiation.

Combat medical care provides unique challenges and opportunities for military medical teams. The austerity of the environment severely limits access to many diagnostic and therapeutic tools. ⋯ Furthermore, US guidance may assist in the performance of some procedures performed in battlefield medical care. This review will provide an overview of the history, current status, limitations and potential future of US utility for the battlefield.

Review Comparative StudyComparison of duplex and nonduplex transcranial Doppler ultrasonography.
Transcranial Doppler ultrasonography is essential in the management of children with sickle cell anemia and is a valuable adjunct to the evaluation of a variety of intracranial pathologies in children and adults, including vasoconstriction caused by subarachnoid hemorrhage, demonstration of major intracranial vessel stenoses or occlusion, determination of brain death, demonstration of the nidus of arteriovascular malformations, and assessment of cerebral hemodynamics after trauma, stroke, or migraine. There are 2 types of transcranial Doppler equipment currently available: nonduplex (nonimaging) and duplex (imaging). The purpose of this review is to compare and contrast the clinically relevant differences between these 2 types of equipment.
