Lessons Learned From the Use of Human-Centered Design Approaches to Improve Nutrition in Nigeria.

Improving children's diets from 6 to 24 months can support children's survival, growth, and development, but progress toward this goal has stalled globally. Human-centered design offers a new approach to resolving program challenges, especially when integrated with social and behavior change (SBC) theory and rigorous evaluation. Two human-centered design processes were conducted.

Understanding reasons for image rejection by radiologists and radiographers.

Introduction: A core element of a radiographer's role is the decision on whether a radiograph is sufficient for diagnosis, or a repeat examination is needed. Studies illustrate the disagreement on the diagnostic value of radiographs between radiographers and radiologists, which may influence repeat examinations. This study investigates if parameters contributing to image quality are possible determinants to explain the difference between professions.

Benign Osseous Tumors and Tumor-Like Conditions.

We will provide an imaging-focused discussion of 3 benign bone tumors that do not fit in the categories of cartilaginous tumors or osteoid tumors. We have chosen giant cell tumor of bone, unicameral bone cyst, and fibrous dysplasia. All 3 of these entities are common enough that one does not have to be a musculoskeletal radiologist in a cancer hospital to encounter them occasionally, but none of them should be seen frequently.

Osteoid Tumors of Bone.

We present a review of several bone (osteoid)-forming tumors including enostosis, osteoid osteoma, osteoblastoma, and osteosarcoma. These entities were chosen because they are reasonably common-neither seen every day nor rare. When applicable, recent information about the lesions is included.

Chondroid Tumors of Bone.

Recent scholarship on enchondroma, chondrosarcoma, and chondroblastoma is presented. The focus of this article is on the imaging appearance of these tumors and the means by which they can be distinguished from one another by both clinical and imaging criteria.
