Key result
Advanced MRI links primary aldosteronism to muscle potassium depletion and sodium accumulation that reverse post-treatment.
Why the study?
Current clinical diagnostics assess only extracellular potassium concentrations, whereas noninvasive imaging of tissue potassium distribution could provide novel pathophysiologic insights in primary aldosteronism.
Does combined 7-T 39K and 23Na MRI detect alterations in skeletal muscle K+ and Na+ distribution in participants with primary aldosteronism?
Comparison
Participants with primary aldosteronism before and after standard therapy vs matched controls
Design
Prospective pre-post and cross-sectional case-control study
Follow-up
Approximately 4 months

May enable noninvasive monitoring of treatment efficacy beyond serum electrolytes in primary aldosteronism; extends prior extracellular-focused work to skeletal muscle.
Does combined 7-T 39K and 23Na MRI detect alterations in skeletal muscle K+ and Na+ distribution in participants with primary aldosteronism?
Combined 7-T 39K and 23Na MRI can noninvasively detect aldosterone-mediated tissue electrolyte shifts and their reversal following treatment in patients with primary aldosteronism.
Kopp et al. (2026) studied this question. 7-T 39K MRI showed that primary aldosteronism causes muscle K+ depletion (72.7 vs 79.1 mmol/L, P=0.02) and Na+ increase, reversed after treatment.
