Athletes can have pain derived from fractures or alternate pathology. Skeletal scintigraphy may detect abnormalities before anatomic imaging and provides a practical tool for whole-body imaging. However, study interpretation in children can be challenging. This pictorial essay describes a technique for pediatric skeletal scintigraphy and reviews findings commonly encountered in athletes. ⋯ Skeletal scintigraphy complements anatomic findings in pediatric athletes. Familiarity with imaging technique and study interpretation can improve diagnosis.

ReviewAssessment of lung inflammation with 18F-FDG PET during acute lung injury.
The purpose of this review is to describe the current experimental and clinical data regarding the fundamentals and applications of (18)F-FDG PET during acute lung injury (ALI) and acute respiratory distress syndrome (ARDS). ⋯ Lung inflammation is a key feature of ALI. During ALI, FDG PET can be used to monitor lung neutrophils, which are essential cells in the pathophysiologic mechanisms of ALI. Pulmonary FDG kinetics are altered during experimental and human ALI and are associated with regional lung dysfunction, histologic abnormalities, and prognosis. FDG PET may be a valuable noninvasive method for gaining comprehensive understanding of the mechanisms of ALI/ARDS and for evaluating therapeutic interventions.

The purposes of this review are to summarize the causes of recurrent pain after percutaneous vertebroplasty and to discuss the incidence, clinical symptoms, risk factors, image findings, treatment and prognosis, and prevention of such pain. ⋯ Percutaneous vertebroplasty is widely used to treat patients with symptomatic osteoporotic compression fractures. Although the procedure relieves the pain of the compression fracture, recurrent back pain after percutaneous vertebroplasty is common.

ReviewOptimizing detectability of renal pathology with MDCT: protocols, pearls, and pitfalls.
The purpose of this article is to review MDCT acquisition protocol parameters and interpretative practices for evaluating genitourinary lesions other than classic renal cell carcinoma, to optimize lesion detectability and accurately characterize pathologic abnormalities. ⋯ With the goal of refining interpretative performance, this pictorial essay shows the patterns of conspicuity unique to each genitourinary pathologic abnormality, presents experience-based recommendations to improve detection and characterization using multiphasic MDCT, and describes pitfalls to be avoided.
