Over the last decade, the attempt to produce MR images that provide bony detail comparable to CT has resulted in multiple different techniques including various VIBE sequences, UTE/ZTE sequences, and synthetic CT.

StarVIBE is a sequence primarily designed for free-breathing body and pediatric imaging, but it also offers several advantages for 3D bone imaging. While StarVIBE does not have the very short echo times (TEs) of ultra-short-TE and zero-TE sequences, its repetition time (TR) and TE are still relatively short compared to other pulse sequences. This characteristic of volume interpolated breath-hold examination (VIBE) makes it a suitable candidate for 3D bone imaging.

The StarVIBE sequence for bone imaging is isometric and provides high-resolution images that are reformattable.
The images also provide excellent cortical and trabecular detail in bony structures, as well as excellent visualization of soft tissue mineralization. The sequence also stands up well when dealing with metal artifact and is comparable to metal reduction sequences in its ability to reduce metal
artifact. Additionally, there is no loss of signal when relevant anatomy is distant from the isocenter, which is particularly useful when imaging joints such as the shoulder and the hip.

What are the T-score values used in DEXA, and how are they calculated? #BoneHealth #JointCare #HealthyBones #Osteoarthritis #BoneResearch #JointHealth #ImagingInnovation
#StrongBones #BoneWellness #CartilageCare #BoneImaging #BoneStrength www.linkedin.com/in/tanuj-pur...

$T-scores help clinicians to interpret the measurements of bone mineral density (BMD) made using DEXA (Dual-Energy X-ray Absorptiometry) scans and find out whether patients have osteoporosis or other bone health issues. T-score compares a patient’s BMD measurement to the average BMD of a group of healthy young adults of the same sex and ethnic background and is calculated using the following equation: T-score = (Patient's BMD - Mean BMD of Young Adult Reference Group) / (Standard Deviation of Young Adult Reference Group BMD) Why it matters: T-scores indicate the patient’s risk of suffering a fragility fracture and their bone health status. A lower T-score means weaker bones and a higher risk of fractures. T-score categories (as defined by the World Health Organisation) are normal: T-score ≥ -1.0: Osteopenia (low bone mass): T-score between -1.0 and -2.5; Osteoporosis: T-score ≤ -2.5; Severe Osteoporosis: T-score ≤ -2.5 with fractures.$
