This article focuses on the pharmacokinetics of [18F]NaF in bones, and various semi-quantitative and quantitative methods for quantifying regional bone metabolism using [18F]NaF PET images. (wikipedia.org)

A bone density screening uses x-rays to measure the amount of calcium and other important minerals within a patient's bones. (acadianaimaging.com)
Due to high blood levels of Calcium from increased bone breakdown kidney stones may occur. (news-medical.net)

Assessing a key aspect of bone architecture, for which clinicians can now be reimbursed under Medicare, can significantly improve the ability to predict a patient's risk for bone fracture. (medscape.com)

After your procedure, we can quickly transmit images and our reports to your designated physicians. (acadianaimaging.com)
The type of imaging procedure that your doctor may suggest will depend on your health concern and the part of the body that is being examined. (cdc.gov)
Making certain the least possible amount of radiation needed to obtain a good quality image is used for your procedure. (cdc.gov)
If you are pregnant, the doctor may decide that it would be best to cancel the medical imaging procedure, to postpone it, or to modify it to reduce the amount of radiation. (cdc.gov)
Depending on your medical needs, and realizing that the risk is very small, the doctor may feel that it is best to proceed with using a medical imaging procedure as planned. (cdc.gov)

We present a case of chondrosarcoma of the hyoid bone with imaging, surgical, and pathologic correlation, and a review of the literature. (ajnr.org)

Imaging -- particularly CT -- is an effective tool for guiding percutaneous soft tissue and bone mass biopsies in children, according to a study published January 19 in the Annals of Surgical Oncology . (auntminnie.com)
These biopsies are sometimes done with a needle to take a sample of the bone. (news-medical.net)

The bones being examined absorb a low-dose X-ray that penetrates through soft tissue and bone. (independentimaging.com)

The search terms were ' bone ' AND 'superscan' OR 'superscan' in the PubMed database from 1980 to November 2020. (bvsalud.org)

It makes its calculations by sending a thin invisible beam of low dose X-rays with two energy peaks through the bones and soft tissue. (smdi.net)
Fat saturation is commonly used in MR imaging to suppress signal from adipose tissue. (medscape.com)

Most people's bones become thinner as they age. (acadianaimaging.com)

Positron emission tomography is a functional imaging technique that uses [18F]NaF radiotracer to visualise and quantify regional bone metabolism and blood flow. (wikipedia.org)
In this study, we used imaging technology to quantify the presence of collagen in bone samples in a non-destructive way to select the most suitable samples (or sample regions) to be submitted to radiocarbon dating analysis. (nature.com)

The T-score determines your fracture risk and compares the amount of bone measured in your body compared to the optimum bone mass for your gender. (independentimaging.com)

Rheumatoid arthritis (RA) is traditionally considered a synovial-centred disease, with pannus invasion causing bone erosion. (bmj.com)
Additionally, a person with rheumatoid arthritis is at risk of reduced bone density, as is a person of slight build and anyone who has health conditions that are generally associated with osteoporosis. (independentimaging.com)

therefore, checking the state of underlying bone for disease is important if such a fracture is suspected (see the first image below). (medscape.com)
When you know that the microarchitecture is normal, you're a lot less concerned that they actually have a bone disease of osteoporosis," Thacker said. (medscape.com)
Paget's disease of the bone is a rare condition affecting the elderly and it primarily involves a faulty bone metabolism. (news-medical.net)
In early stages of the disease more bone is broken down and the bone may appear as riddled with black holes on X rays. (news-medical.net)
Later in the disease process these black areas can take the shape of a 'V,' with denser, thicker bone following behind it. (news-medical.net)
Hearing loss may be the first to be detected in Paget's disease affecting the skull bones. (news-medical.net)

It is an effective way to diagnose bone-related health problems, such as osteoporosis, and to assess the risk of developing them. (independentimaging.com)
Your doctor will then diagnose your bone density using two scores. (independentimaging.com)
Imaging procedures are medical tests that allow doctors to see inside the body in order to diagnose, treat, and monitor health conditions. (cdc.gov)

Specialized DEXA technology has software that calculates and display bone density measurements on a computer monitor. (smdi.net)
A third set of images with a resolution of 165 microns was created by downscaling the microCT measurements. (tue.nl)
