Clinical Study on a New Diagnostic Strategy for Osteoporosis and Sarcopenia in Chronic Kidney Disease Patients Based on MRI-FF

9. juni 2026 opdateret af: Dongliang Zhang, MD, Capital Medical University

A Clinical Study on Establishing a New Diagnostic Strategy for Osteoporosis and Sarcopenia in Patients With Chronic Kidney Disease Based on MRI-FFR

This is a single-center, observational cohort study aiming to validate the diagnostic value of MRI-FF in identifying osteoporosis and sarcopenia in patients with chronic kidney disease (CKD). A total of 868 participants, including 434 CKD patients and 434 non-CKD controls, will be enrolled at Beijing Jishuitan Hospital. All subjects will undergo MRI-FF scans of the lumbar spine and thigh to assess bone mineral density and muscle fat fraction. The primary objective is to evaluate the correlation between MRI-FF parameters and conventional diagnostic criteria for osteoporosis and sarcopenia, as well as to determine the optimal cut-off values for early detection. The study duration is from March 2026 to December 2028.

Studiebefolkning

The study population consists of two groups: 434 patients with chronic kidney disease (CKD) and 434 age- and sex-matched healthy controls without CKD. All participants are adults aged 18-80 years old who are able to complete the required MRI scans.

Beskrivelse

Inclusion Criteria:

  1. Age between 18 and 80 years old.
  2. Able to understand and sign the informed consent form.
  3. Able to complete MRI-FF scans of the lumbar spine and thigh.
  4. For CKD group: Confirmed diagnosis of chronic kidney disease (eGFR < 60 mL/min/1.73m² for ≥3 months).
  5. For control group: No history of chronic kidney disease and normal renal function.

Exclusion Criteria:

  1. Contraindications to MRI (e.g., pacemaker, metal implants, severe claustrophobia).
  2. History of primary bone metabolic disorders (e.g., osteoporosis, hyperparathyroidism) unrelated to CKD.
  3. Current use of anti-osteoporotic drugs (e.g., bisphosphonates, teriparatide).
  4. Severe lower limb deformity or amputation affecting thigh muscle assessment.
  5. Inability to cooperate with the scan due to cognitive impairment or severe illness.

Kohorter og interventioner

Gruppe / kohorte
Intervention / Behandling
Chronic Kidney Disease (CKD) Group
Patients with chronic kidney disease (CKD) who undergo MRI-FF scans of the lumbar spine and thigh to evaluate bone mineral density and muscle fat fraction.
MRI fat-fraction (MRI-FF) scan of the lumbar spine and thigh, performed once for all participants to assess bone mineral density and muscle fat fraction.
Non-CKD Control Group
Control participants without chronic kidney disease, undergoing the same MRI-FF scans as the CKD group for comparison.
MRI fat-fraction (MRI-FF) scan of the lumbar spine and thigh, performed once for all participants to assess bone mineral density and muscle fat fraction.

Resultatmål
Foranstaltningsbeskrivelse
Tidsramme
Correlation between MRI-FF-derived bone mineral density and DXA measurements
Tidsramme: At the time of the MRI-FF scan (baseline, one-time assessment)
The primary outcome is the correlation coefficient between MRI fat-fraction (MRI-FF) parameters and standard dual-energy X-ray absorptiometry (DXA) bone mineral density values in the lumbar spine of CKD patients and controls.
At the time of the MRI-FF scan (baseline, one-time assessment)
Diagnostic performance of MRI-FF for sarcopenia using muscle fat fraction
Tidsramme: At the time of the MRI-FF scan (baseline, one-time assessment)
The secondary outcome is the diagnostic accuracy (sensitivity, specificity, AUC) of MRI-FF-derived thigh muscle fat fraction in identifying sarcopenia, based on standard diagnostic criteria.
At the time of the MRI-FF scan (baseline, one-time assessment)
