Pharmacokinetics and pharmacodynamics (mode of action) As already described, the diet contains almost exclusively iodine in the form of its salts, i.e. in the form of iodide. In the gastrointestinal tract, this is absorbed and passes into the so-called extracellular fluid, i.e. the fluid that is present between the cells. Iodine, which is released by … Pharmacokinetics and pharmacodynamics (mode of action) | Iodide
Effect of excess iodine on the synthesis of thyroid hormones During normal functioning of the thyroid gland, a permanent excess of iodine (several hundred milligrams with an actual daily requirement of 200 micrograms) inhibits iodine absorption and thyroid hormone production. This effect is known as the Wolff-Chaikoff effect. In the past, this effect was used … Effect of excess iodine on the synthesis of thyroid hormones | Iodide

Diagnostics The notion of a cold node in the thyroid gland is derived from the findings of a scintigraphy. A scintigraphy is a method of nuclear medical imaging. It involves injecting the patient with radioactive but non-harmful substances that are stored in certain tissues, for example in the thyroid gland. Using a so-called gamma camera, … Diagnostics | Cold knot on the thyroid gland
Scintigraphy (also: scintigraphy) is an imaging procedure in medicine. With the help of the injection of low-level radioactive substances and a gamma camera, certain tissue structures can be made visible. What is scintigraphy? Scintigraphy uses an injection of low-level radioactive material and a gamma camera to make certain tissue structures visible. Scintigraphy is used primarily … Scintigraphy: Treatment, Effects & Risks
Diagnosis The patient is asked about his medical history (= anamnesis) at the beginning of the contact with the doctor.
