Active Acromegaly
All study subjects with acromegaly will be studied twice - once during the active stage of their disease (pre-treatment) and a second time: 3 months after treatment of acromegaly. Controls will be studied at one time point.
Healthy controls


Ages Eligible for Study:   18 Years to 75 Years
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   Yes
Sampling Method:   Non-Probability Sample
Study Population
Thirty-two study subjects will be studied: 1) patients with active acromegaly, and 2) healthy controls. Study subjects with acromegaly will be prescribed treatment for acromegaly by their healthcare providers, and this study will not interfere in anyway with clinical care and will not provide surgery, medications or other forms of clinical care.

Inclusion Criteria:

  • Ages 18 - 75 yr (both groups)
  • Study subjects with active acromegaly
  • Healthy controls

Exclusion Criteria:

  • Serum creatinine or alanine aminotransferase (ALT) > 2 times the upper limit of normal, metastatic cancer.
  • Controls will be receiving no medications and have no chronic diseases, including cancer, hypertension or diabetes mellitus.
  • Contraindications to MRI imaging (both groups) like those with certain metal implants, surgical clips or pacemakers.
  • Pregnant women
