Techniques to Reduce Bone Densitometry Radiation Dose

bone densitometry radiation dose

In this article we talk about bone densitometry radiation dose and the techniques that radiologic technologists can apply to reduce it. The two key principles in patient radiation protection are justification and optimization. Justification implies that any X-ray exposure is justified clinically. It means the examinations that will not affect the patient’s care are avoided. Once an examination is justified, optimization consists of activities that reduce bone densitometry radiation dose. This means delivery of the smallest possible dose to the patient.

Radiation Dose in Modern Diagnostic Radiology

radiation dose control

Over the past several decades, the use of ionizing radiation in medical imaging has increased dramatically. This has resulted in a substantial increase in the radiation dose humans are exposed to. In 1950, approximately 25 million radiographic and fluoroscopic exams were performed. This number skyrocketed to nearly 300 million by the mid-2000s. In the 1980s, only 15 percent of all artificial radiation exposure was on account of medical imaging; by the mid-2000s, this figure had risen to almost 50 percent.

Patient Radiation Dose Measurement in Fluoroscopy and CT Examinations

Fluoroscopy and patient radiation dose

Radiation dose represents the energy deposited per unit mass of tissue. It is typically measured in Gray (Joules/kg). This deposition of energy may cause damage the tissues, and therefore, patient radiation dose must be measured and monitored. Patients are exposed to some of the largest doses of radiation during fluoroscopically-guided procedures and computed tomography examinations. Radiologic technologists play a key role in limiting this dose, based on the ALARA principle, by using the correct imaging techniques.

Personal Radiation Monitoring Devices: Features and Safety Issues

personal radiation monitoring devices

National regulations determine whether healthcare providers who work in radiology departments require radiation monitoring. In some countries it is mandatory for all personnel exposed to radiation to wear dose-monitoring badges. If individual monitoring is not mandatory, it may be useful to monitor the workplace by placing a dosimeter at a point of interest such as the operator’s position during the image acquisition. In addition, special precautions may be necessary for pregnant workers. Are you monitoring your radiation exposure at work? Do you know the correct way to use your radiation monitoring device? Read about the features of personal radiation monitoring devices used by radiologic technologists.
