About isotope examination in general

 

In case of isotope examinations most frequently we administer the isotopically labeled active agent intravenously (maybe orally or by inhalation). Depending on the type of the examination we choose a substance which bounds to or is excreted by the organ in question. Depending on the physiological functions of this organ after the injection more or less time is needed for waiting before the imaging is performed. Although there are examinations in case of which taking the images can only be done after some days.

The time needed for imaging is not unified, there are shorter and longer examinations, so the accompanying parent or relative can stay together with a child or a miserable patient.


Preparations on the examination's day:

  • Examinations are performed based on referrals. Because of the radioactive (lytic) substances it is important that the patient should arrive on time, because in case of delay the examination cannot be performed.
  • For the registration patients should take the following with them: referral, identification card, health insurance card, previous findings and discharge papers.
  • In order to avoid any unnecessary radiation exposure the examined patients should not take their child with them into the laboratory.
  • Most of the examinations do not require any preparations (patients are allowed to eat and to take their medications as usual)
  • Examinations that require special preparations:
    • Isotope examination of the liver and biliary tract – it is performed on an empty stomach
    • For examination of bones- patients should take 1 liter of fluid with them
    • For examination of lungs- patients should nesessarily take the previous chest X-ray findings with them
    • In case of renal examination- it is important to drink an excessive amount of fluid


Examination risks

The diagnostic and therapeutic effects of radiation have been used in medical practice for decades. The examination is associated with low radiation load like the X-rays. The radiation load is identical with an average person’s half-one and a half year radiation load – deriving from cosmic radiation and natural background radiation. The radiation load during these examinations is 5-10% of the dose generally regarded as safe, that a physician or an assistant working with radioactive substances may get in a year. After the examination patients can go to community and they can use toilets and bathrooms without any substantive risk for others. If patients have any questions or problems concerning the examination they can turn trustingly to our nuclear medicine specialists.


Side effects:

The radioactive substance that patients get does not have any side effects. Allergic symptoms usually do not appear.


After the examination:

After the examination is over, patients can eat and drink as they usually do. On the day of the examination meeting pregnant women and children under the age of 16 should be avoided anyway.


Results, findings:

We send the results of the examination after 3 workdays to the therapist or to the patient. If it is needed the patient can discuss the findings with one of our nuclear medicine specialists.


For our female patients:

Performing an isotope examination is not recommended for pregnant and presumably pregnant women. We ask you to tell our colleagues if you are pregnant or breast-feeding before the examination. If the therapist knowing the fact still thinks that the examination is necessary performing it is not contraindicated.
