Visualization of spinal cord motion associated with the cardiac pulse by tagged magnetic resonance imaging with particle image velocimetry software.
The purpose of this study was to evaluate whether or not tagged magnetic resonance (MR) imaging with particle image velocimetry (PIV) software could reveal spinal cord motion clearly. ⋯ Tagged MR imaging combined with PIV software, referred to as tagged MR image velocimetry, revealed spinal cord motion associated with the cardiac pulse, especially in the cervical spine.

ReviewPulmonary parenchymal involvement of low-grade lymphoproliferative disorders.
Lymphoid tissue is a normal component of the lung. The various lymphoproliferative diseases affect the lung parenchyma. ⋯ The examples include follicular bronchiolitis, lymphocytic interstitial pneumonia, plasma cell granuloma, Castleman disease, lymphomatoid granulomatosis, and mucosa-associated lymphoid tissue lymphoma. Pathologic correlation is helpful for understanding imaging findings and their pathophysiology.

Comparative StudyMultidetector computed tomography of pediatric lateral condylar fractures.
The objective of this study was to compare lateral condylar fracture characterization using radiographs and multidetector computed tomography (MDCT) of the elbow and to evaluate outcomes in a group of children managed based on MDCT findings. ⋯ Multidetector computed tomography is a highly reproducible means of characterizing pediatric lateral condylar fractures and frequently demonstrates disruption of the epiphyseal and articular cartilage in patients with fracture displacement greater than 2 mm. The findings of MDCT may lead to altered treatment in patients with fracture displacement near the surgical threshold of 2 mm.

Case Reports Comparative StudyComprehensive multidetector computed tomography assessment of severe cardiac contusion in a pediatric patient: correlation with echocardiography.
Multidetector computed tomography (MDCT) cardiac findings in an unconscious teenager after blunt chest trauma are presented. Multidetector computed tomography enabled accurate comprehensive evaluation of the coronary arteries, myocardial perfusion, and left ventricular function. This case illustrates the full capabilities of MDCT in the evaluation of cardiac contusion in a noncooperative pediatric patient.

Pathologic subgroups of nonspecific interstitial pneumonia: differential diagnosis from other idiopathic interstitial pneumonias on high-resolution computed tomography.
To determine whether the subtypes of nonspecific interstitial pneumonia (NSIP) could be differentiated from other idiopathic interstitial pneumonias (IIPs) on the basis of findings on high-resolution computed tomography (CT). ⋯ In most patients, NSIP can be distinguished from other IIPs based on the findings on high-resolution CT. Only a small percentage of patients with predominantly fibrotic NSIP (group 3 NSIP) show overlap with the high-resolution CT findings of UIP.
