ReviewMagnetic resonance imaging features of the discrete epiphyseal radiolucency: a problem-solving approach to differential diagnosis.
Discrete radiolucencies in the epiphysis of the long bones may be a major radiographic finding in many arthropathies and synovial-based processes, and also in various osteolytic tumors and tumor-like lesions. In addition, a number of miscellaneous bone disorders, particularly infection and avascular necrosis, may present as discrete epiphyseal radiolucencies. Magnetic resonance imaging is frequently used in the diagnostic workup of these lesions. Our purpose was to review and illustrate, in a problem-solving approach, the potential contributions of magnetic resonance imaging in the characterization of discrete epiphyseal radiolucent lesions.

ReviewMagnetic resonance of acute appendicitis: pearls and pitfalls.
Acute appendicitis is the most common surgical abdominal emergency. Although the clinical diagnosis can be made accurately in typical cases, imaging plays an important role in improving diagnostic accuracy of this condition, especially when the clinical diagnosis is uncertain. Magnetic resonance imaging is an emerging promising technique for the diagnosis of acute appendicitis, especially in patients with nondiagnostic ultrasound and in patients where radiation is a clinical concern. In the following review, the role of magnetic resonance in the diagnosis of appendicitis will be discussed.

ReviewMagnetic resonance imaging of pelvis and hips in infants, children, and adolescents: a pictorial review.
Due to its superior tissue resolution, magnetic resonance imaging has become the modality of choice for assessing pathologies of soft tissues, joints, cartilage, and bone marrow. This is also true in the pediatric population. This article reviews magnetic resonance imaging appearances and techniques for a variety of congenital abnormalities and acquired conditions including posttraumatic, infectious, inflammatory, ischemic, metabolic, benign, and malignant processes.

Sixty-four multi-detector row computed tomography in multitrauma patient imaging: early experience.
Sixty-four multi-detector row computed tomography (64-MDCT) offers the possibility of increasing the application of CT in multitrauma imaging. 64-MDCT affords significant increases in imaging speed while allowing for subisotropic voxel slice thicknesses. We have recently installed two 64-MDCT scanners in our Level I trauma center. Our routine protocols using these new scanners are detailed. ⋯ With the opportunity to image from head to toe in seconds with submillimeter slice thicknesses, radiologists must be constantly vigilant in their efforts to limit radiation. Novel techniques such as automated dose modulation currently offer means of reducing radiation doses. Though several technical challenges are faced, 64-MDCT represents an evolution in multitrauma imaging.
