Keeping Bones Strong and Healthy in Children and Adolescents

keeping bones strong and healthy in children

In this article we give a brief overview of some of the factors that affect bone health in children and adolescents. The period of life from birth to adolescence is vital in terms of building a healthy skeleton. It is also important in terms of developing habits that aid in keeping bones strong and healthy. These habits can help maintain robust bone health through the individual’s adult and older years.

Advantages of DXA Scan and Best BMD Testing Technology

BMD testing guidelines

The importance of DXA is underscored by the fact that BMD is a strong independent predictor of an individual’s risk of sustaining fragility fractures. A clear relationship has been established in postmenopausal females between BMD results and the risk of osteoporotic fractures. For every standard deviation drop in DXA-calculated bone density (equivalent to a 10-12 percent bone loss in the spine), the individual’s fracture risk increases by up to 2.5 times. What are the advantages of DXA scan and how does it compare to other modalities used to measure bone density?

Types of Radiation: Why Are X-Rays Used in Medical Imaging?

Radiation is the transmission of energy through space. There is typically a source of the radiation, a radiation beam, and some material which absorbs the radiation. In diagnostic radiography, the X-ray device is the source of radiation and it emits a radiation beam that is absorbed by the patient. What are the different types of radiation? And why are X-rays preferred for use in medical imaging?

Good Nutrition for Healthy Bones in Adults

good nutrition for healthy bones

A diet that is considered appropriate for optimal bone health is also recommended for overall good health and the prevention of chronic diseases. Thus, healthcare providers have an opportunity, at every patient encounter, to provide counseling with regards to good nutrition for healthy bones. This nutritional counseling is vital to prevent many common “lifestyle” diseases such as obesity, hypertension, and diabetes. Therefore, healthcare professionals should not miss this excellent opportunity to reinforce the importance of a healthy balanced diet in terms of both overall health and bone health.

DXA Scan Errors: Do You Know These Common Sources?

DXA scan errors patient positioning

Bone density testing is an important tool in the management of osteoporosis. Several different radiological modalities are available to measure bone density. Although each one has its own advantages and disadvantages, DXA is the most widely used. However, there are certain DXA scan errors that DXA operators and general radiographers should be aware of.

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.
