The improvement of conventional imaging techniques has led to an increased detection rate of different adrenal tumors. Since those tumors can belong to a variety of entities the therapeutic consequences also show considerable variation. In order to definitely determine the type of tumor, invasive procedures like CT guided biopsies are often required, which could be avoided by a tumor specific imaging method. The presently available scintigraphic procedures are either time consuming and lead to high radiation exposure or are technically demanding. The steroidogenic enzymes CYP11B1 (11ß-hydroxylase)and CYP11B2 (aldosterone synthase)are expressed exclusively in the adrenal cortex and therefore represent suitable targets for a specific imaging technique. In our project we evaluate 123I-Iodometomidate which binds to both CYP11B enzymes as radiotracer for adrenal scintigraphy.

The purpose of this study is to find out if your adrenal glands are normal or abnormal. This can be determined by whether or not your adrenal gland concentrates more of a labeled building ...
Context. Nuclear imaging plays a central role in management of chromaffin-tissue derived tumors because tumor cells exhibit peptide receptors and proteins involved in metabolism that can b...
The underlying goal of this study is to assess [123I]MNI-420 SPECT imaging as a tool to detect A2aR density in the brain of PD and HD research participants to be compared with similarly ag...
PET (positron emission tomography) scans combined with a radioactive tracer will be used to identify and analyze tumors. Currently, the most common tracer used to analyze neuroblastoma tum...
The management of adrenal crisis is often problematic and the time to adequate treatment is frequently delayed.The aim of the study is to evaluate the management of adrenal emergencies req...
Testicular adrenal rest tumors (TART) can cause infertility in congenital adrenal hyperplasia (CAH) males.
Distinguishing adrenal incidentalomas (5% of all abdominal CT scans) from metastasis is a frequent diagnostic challenge in primary malignancies with a propensity for adrenal spread, such as lung cance...
We describe the case of a 4.8-year-old boy who presented with adrenal crisis. The advent of symptoms of adrenal insufficiency in the patient was at around 2 years of age. Congenital causes of adrena...
We report a case of congenital adrenal hyperplasia in a 29 year old patient, who presented with testicular pain, bilateral testicular masses, and oligospermia. Ultrasonography confirmed, in both testi...
Neoplasm derived from displaced cells (rest cells) of the primordial ADRENAL GLANDS, generally in patients with CONGENITAL ADRENAL HYPERPLASIA. Adrenal rest tumors have been identified in TESTES; LIVER; and other tissues. They are dependent on ADRENOCORTICOTROPIN for growth and adrenal steroid secretion.
Conditions in which the production of adrenal CORTICOSTEROIDS falls below the requirement of the body. Adrenal insufficiency can be caused by defects in the ADRENAL GLANDS, the PITUITARY GLAND, or the HYPOTHALAMUS.
The inner portion of the adrenal gland. Derived from ECTODERM, adrenal medulla consists mainly of CHROMAFFIN CELLS that produces and stores a number of NEUROTRANSMITTERS, mainly adrenaline (EPINEPHRINE) and NOREPINEPHRINE. The activity of the adrenal medulla is regulated by the SYMPATHETIC NERVOUS SYSTEM.
A pair of glands located at the cranial pole of each of the two KIDNEYS. Each adrenal gland is composed of two distinct endocrine tissues with separate embryonic origins, the ADRENAL CORTEX producing STEROIDS and the ADRENAL MEDULLA producing NEUROTRANSMITTERS.
A sterol usually substituted with radioactive iodine. It is an adrenal cortex scanning agent with demonstrated high adrenal concentration and superior adrenal imaging.
