The nuclear medicine department performs in vitro tests (RIA-laboratory blood tests) and in-vivo (scintigraphy)
The department is equipped with system gamma-Camera Dual head of General Electric. The tests that are carried out, cover the entire range of static, dynamic and SPECT studies. Scintigraphy is widely used for the detection of small areas of tissue damage. A special radioactive drug is administered intravenously in most cases and sometimes, the patient drinks a radioactive solution. This drug differs depending on the organ for which they get tested.
Once inserted into the body, the radioisotope is directed to the organ that suffers where it emits gamma rays (similar to X-rays but shorter wavelength), which can be detected by a gamma-Camera. Then the gamma-Camera is placed behind the body, in the area of the under examination organ. This camera receives signals from the radioactive drug and then via computer, takes place the appropriate treatment in order to get the test result. For carrying out the examination, the patient may have to wait up to four hours. The duration of the process depends on the type of examination.
The tests carried out are:
- Myocardial scintigraphy (at stress and rest).
- Bone (simple, 3-phases and SPECT)
- Kidney (static and dynamic imaging) and renal function
- Thyroid, parathyroid, parotid
- Lung (perfusion and aeration)
- Cysteography, adrenal, liver - spleen
Blood tests by the RIA method
For the determination of hormones and other substances in the blood, the RIA method (Radio-Immuno-Assay) is considered the most accurate measuring method. With the use of radioisotopes, the department can provide laboratory blood results with absolute accuracy compare to the microbiological methods. It is required a special license and the machine to carry out such tests, and based on the curve of the standard solutions, the lab is able to give accurate results rather than the approximation results of the microbiological methods.
With this method therefore the hormonal tests and neoplasmatic markers such as: T3, T4, TSH, FT3, FT4, TG, Anti-TPO, Anti-TG, CEA, AFP, CA 15-3, CA 125, CA 19-9, CA 72-4, CA 50, PSA, free PSA, b-HCG, SHBG, D4-Androstendioni, DHEA, Prolactin PRL, 17-oH-PG, PTH (parathyroid hormone), Progesterone (PRG), serum testosterone, free testosterone etc, can be measured with pinpoint accuracy. The procedure requires no preparation and the results are given after some time, depending on the test.
