Meckel’s Diverticulum Scintigraphy

CONTINUE READING...

A Meckel’s Diverticulum Scintigraphy is a nuclear medicine test that detects the abnormally-located gastric mucosa. Gastric mucosa is the mucous membrane layer of the stomach. Meckel’s diverticulum is an abnormality in the small intestine that is present at birth.

  o Barium studies.
  o Colonoscopy.
  o In vivo Radiolabeled RBC study.
• Please inform the Nuclear Medicine staff if you have had surgery on your bowel before.
• 4 days before the test STOP* the following medications:
  o Potassium.
  o Perchlorate.
  o Ethosuximide (Zarontin).
  o Aluminum-containing antacids.
  o Aspirin.
  o Laxatives.
  o Omeprazole (Losec or Prilosec).
  * Check with your referral doctor if you can stop taking these medications and use alternative ones.
• Do not stop other medications.
• Fasting is required for this procedure:
  o Adults: Full fast (no food and water) 4 hours before the procedure.

❰❰ RADIATION SAFETY

Are Nuclear Medicine procedures safe?2020-12-08T10:21:58+03:00

Nuclear medicine diagnostic procedures are safe except for pregnant ladies, unless it is requested by the physician for exceptional cases. However, the procedure better to be discussed with the doctor to know the desired benefits of the test and the alternative procedures, or you can ask the the nuclear medicine specialist about the procedure.

Should I wear a lead apron?2020-11-25T14:38:49+03:00

No, you shouldn’t because nuclear medicine scans use high-energy radioisotopes, the radiation passes directly from the other person without interacting with tissues. In contrast, wearing a lead apron slows down the radiation beam, which allows it to deposit its energy in the body and interact with tissues.

Are there risks from radiation?2020-12-08T12:45:27+03:00

The risks from diagnostic doses are usually small compared to other lifetime risks to which the patient is exposed to and the amount of radiation dose in most diagnostic procedures is less than an x-ray, CT scan, or fluoroscopy.

What is the expected damage from radiation?2020-12-08T10:32:23+03:00

When the body is exposed to radiation, tissue damage may occur, which in turn may damage DNA or chromosomes, increasing the risk of genetic mutations. When a fetus is exposed to radiation doses, it may cause abnormalities in an organ or irreparable damage and if the radiation dose is too high, it may cause the death of the fetus.

The radioactive dose used in diagnostic procedures in nuclear medicine is very low, unlike radiation treatments in which the amount of radioactive dose is high and this gives the desired effect on the tissues or organs when radiotherapy. That is why the patient must undergo a pregnancy test in the event of suspicion or if the pregnancy is uncertain before starting the therapeutic doses.

Does the patient become a danger to his family?2020-12-08T10:51:15+03:00

In diagnostic procedures the radioactivity is very low. However, the patient may be asked to maintain a distance of approximately one meter between him and his family members for a period of time given by the nuclear medicine specialist to protect them from exposure to radiation.

One the other hand, in therapeutic procedures, the patients may present some slight risk to their family members if they do not follow the INSTRUCTIONS ON RADIATION SAFETY given to them by the nuclear medicine specialist.
