ACR Appropriateness Criteria® posttreatment follow-up of prostate cancer.

Although prostate cancer can be effectively treated, recurrent or residual disease after therapy is not uncommon and is usually detected by a rise in prostate-specific antigen. Patients with biochemical prostate-specific antigen relapse should undergo a prompt search for the presence of local recurrence or distant metastatic disease, each requiring different forms of therapy. Various imaging modalities and image-guided procedures may be used in the evaluation of these patients.

Nuclear medicine technologists and unauthorized self-injections.

An Office of Investigation (OI) investigation by the U.S. Nuclear Regulatory Commission (NRC) determined that, on three separate occasions over the past 10 years, technologists in one licensed nuclear medicine program were injected with radiopharmaceuticals without Authorized User knowledge or approval.

Radiation dose from DXA scanning to reproductive tissues of females.

The objective of this study was to use an anatomically arrayed whole-body phantom to measure radiation exposure to the ovaries and uterus during standard dual-energy Xray absorptiometry (DXA) scanning. DXA instrument manufacturers' published entrance skin exposure is about 3 mR (0.77 microC/kg), which is equivalent to the radiation exposure received during a transcontinental plane trip.

Modifiable determinants of bone status in young women.

The purpose of this study was to evaluate the contributions of exercise, fitness, body composition, and calcium intake during adolescence to peak bone mineral density and bone structural measurements in young women. University Hospital and 75 healthy, white females in the longitudinal Penn State Young Women's Health Study were included. Body composition, total body, and hip bone mineral density (BMD) were measured by dual-energy X-ray absorptiometry (DXA), exercise scores by sports-exercise questionnaire during ages 12-18 years, and estimated aerobic capacity by bike ergometry.

Adolescent Caucasian mothers have reduced adult hip bone density.

Objective: To determine the long-term effect of full term teen pregnancy on peak hip bone mineral density.

Design: Longitudinal observational study.

Setting: Academic clinical research center.
