Re-evaluation of Internal Reference for Bone Scintigraphy in Renal Impairment:

Key Points

• This research investigates the effectiveness of the lumbar vertebrae/background ratio in assessing bone metastases in patients with renal impairment.
• Developed and validated the lumbar vertebrae/background ratio as a reference for bone scintigraphy
• Created a corrected score that factors in body composition and renal function
• The lumbar vertebrae/background ratio provided a more accurate assessment of bone metastases compared to the lumbar/kidney ratio
• Corrected score significantly improved evaluation metrics for patients with renal impairment
