What this trial studies

This study aims to explore the tissue potassium loss in patients diagnosed with primary hyperaldosteronism using advanced 39K-MR Imaging at 7 Tesla. Patients will undergo non-invasive imaging to assess tissue sodium and potassium content before and after treatment, which may include adrenal surgery or medication. The study will also evaluate blood pressure, body water distribution, serum electrolytes, and monocyte function to understand the effects of treatment on electrolyte balance.

Who should consider this trial

Good fit: Ideal candidates for this study are individuals diagnosed with primary hyperaldosteronism according to endocrinological guidelines.

Not a fit: Patients with chronic kidney disease stage 3b or below, acute kidney injury, severe congestive heart failure, liver cirrhosis, pregnancy, or contraindications for MRI may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved treatment strategies for patients with primary hyperaldosteronism by addressing potassium deficiencies.

How similar studies have performed: While the approach of using advanced MRI techniques is innovative, previous studies have indicated potential for success in understanding electrolyte disturbances in similar conditions.
