Optimizing the Radiology Experience through Radiologist-Patient Interaction.

Objective The goal of this survey-based study is to explore patients' knowledge of and expectations for radiologists in the outpatient setting.  Materials and Methods A comprehensive survey was distributed to adult patients undergoing knee magnetic resonance imaging (MRI) over a one-year period from September 2015 through August 2016 at an urban, quaternary care academic medical center. Results The survey results demonstrate that only a subset of patients undergoing knee MRI at the institution during the survey period are aware of the role of the radiologist, which is a well-documented fact described in the literature.

Radiographic analysis of solitary bone lesions.

Solitary bone lesions are common diagnostic dilemmas. Conventional radiography is frequently the initial imaging study for evaluation. This article provides an organized approach to analyzing and categorizing these lesions based on radiographs, emphasizes the development of a reasonable and accurate differential diagnosis, and guides the referring physician if further imaging evaluation is warranted.

Radiofrequency ablation of solitary eosinophilic granuloma of bone.

Objective: This article about our initial clinical experience describes the novel application of radiofrequency ablation for the treatment of two cases of solitary eosinophilic granuloma of the bone.

Conclusion: Technical success was achieved in both cases with a prompt clinical response and no treatment-related complications. To our knowledge, this is the first description of the application of radiofrequency ablation for the treatment of solitary eosinophilic granuloma of the bone.

Pitfalls in MR image interpretation prompting referrals to an orthopedic oncology clinic.

Patients referred to the authors' hospital for evaluation on suspicion of a bone or soft-tissue malignancy frequently present to the Orthopaedic Oncology Clinic with magnetic resonance (MR) images that show typical features of nonmalignant or nonneoplastic entities. The purpose of this article is to review the benign entities that may be mistaken by the radiologist for a malignancy and thus lead to needless referral to an orthopedic oncologist. Normal hematopoietic marrow and marrow edema due to a stress reaction may mimic a neoplasm at MR imaging, but knowledge of the typical patterns and locations of these features allows an accurate radiologic interpretation.

Comparison of radiographic texture analysis from computed radiography and bone densitometry systems.

Osteoporosis is a disease that results in an increased risk of bone fracture due to a loss of bone mass and deterioration of bone structure. Bone mineral density (BMD) provides a measure of bone mass and is frequently measured by bone densitometry systems to diagnose osteoporosis. In addition, computerized radiographic texture analysis (RTA) is currently being investigated as a measure of bone structure and as an additional diagnostic predictor of osteoporosis.

Clinical utility of dual-energy vertebral assessment (DVA).

The current study was undertaken to evaluate the clinical utility of DVA, a system for imaging the lateral spine on the Lunar Prodigy densitometer. DVA images were obtained and bone density of the lumbar spine and proximal femur measured in 297 subjects (272 women), aged 64+/-13 years. The images were classified as: normal (N) if no fractures were detected and all vertebrae between T6 and L4 were visualized, fracture (F) if any vertebra had a fracture (defined as 25% or more reduction in the vertebral height) even if some of the other vertebrae could not be visualized, and un-interpretable (U) if at least one of the vertebra between T6 and L4 could not be classified and no fractures were detected in the visualized vertebrae.
