How should a DEXA scan be used to evaluate bisphosphonate therapy for osteoporosis? [PDF]

, 2005
If bone density is evaluated after initiating bisphosphonate drug therapy, it should be tested no earlier than 2 years (strength of recommendation [SOR]: B, based on case series of dual energy x-ray absorptiometry [DEXA] scanning precision and ...

A Pilot Study on the Accuracy of Large Language Models (ChatGPT, Google Bard, and Microsoft Copilot) for Selecting the Correct Modality for Musculoskeletal Clinical Cases According to the ACR's Appropriateness Criteria

iRADIOLOGY, EarlyView.
In this paper we demonstrate that AI models can determine the most appropriate imagining modality for a given musculoskeletal clinical scenario in up to 89% of cases, with some models outperforming others. ABSTRACT Background Large language models (LLMs) are becoming more commonly used in many aspects of radiology.

Bone mineral density assessment for research purpose using dual energy X-ray absorptiometry

Osteoporosis and Sarcopenia, 2018
Dual energy X-ray absorptiometry (DXA) has become the most common method for measuring bone mineral density (BMD) of small animals in metabolic bone disease research, and errors should be minimized in all procedures involved in research studies in order ...

Muscle Ultrasound Echo Intensity Detects Insulin Resistance Before Changes in HbA1c or Fasting Glucose, Independent of BMI

Journal of Ultrasound in Medicine, EarlyView.
Objectives To quantify the association between skeletal muscle echo intensity (MEI), measured by ultrasound, and clinical markers of insulin resistance and glycemic control, and evaluate MEI's diagnostic accuracy in identifying insulin resistance. Methods In this cross‐sectional study, 20 adults with obesity (mean body mass index [BMI] 34.4 ± 2.6 kg/m2,

Bicomponent Mapping of Cortical Bone Using a New Interleaved UTE Imaging Sequence

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose Ultrashort echo time (UTE) MRI enables direct imaging of cortical bone and quantification of its water compartments via bicomponent T2* modeling. However, conventional approaches require multiple separate dual‐echo scans due to limitations in gradient power. This approach is prone to inter‐scan inconsistencies such as motion and signal
