Issues to keep in mind about photothrography in CT scans

Contrast drugs are iodine-containing substances that are used to enhance the degree of contrast of the structure or body fluids during imaging examinations. In addition to the benefits of diagnosis, contrasting drug use may be accompanied by a number of undesirable side effects.

1. When does a comoclass scan require an injection of a edthrotoxic drug?

The majority of comoclass scans for the correct diagnosis of the disease require a photothrectar injection, namely:

  • Comoclass scan of the abdomen – the pelvis requires injections of photoretrosure to diagnose pathology in organs such as the liver-bile, pancreas, spleen, urinary system, uterus-ovaries and pathology of the digestive system.
  • Suspected cases of tumors.
  • The majority of cases of inflammation, anesthesis need to be injected with a photoculative agent, except for pneumonia that has been firmly diagnosed and does not need to be distinguished from other conditions.
  • Vascular diseases such as aneurysms, pseudo-aneurysms, vascular malformation, arterial dissection, arterial stenosis
  • Some special cases: Find the source of cultured vessels of the lungs isolated, assess the re-perfusent area of the lesion, diagnose the degree of wallification of the hematoma under the symosis of the semi-sysentary stage,…

Malformed cerebral blood vessels

2. Contrain specifying of photothrography in CT scans

2.1 Relative contrainttrainnities

  • People with liver failure, debilitation heart failure
  • People with renal failure level III, IV. If injections are required, the doctor should plan hemodialysis for the patient immediately after the injection of a phototholynthotoxic drug.
  • People with multiple myeloma, especially patients with oliguria. If a computer ctect of the scan is required, an infusion should be given to the patient.
  • People with a history of drug allergies, history of asthma, allergic muscles.
  • People with chronic diseases: Diabetes mellitus,yroidism, asthma, sickle cell.
  • Pregnant women: The use of ion-free photoatheses has not been adequately proven to be safe for pregnant women. It is not recommended to use photothritis for pregnant women unless the benefits outweigh the risk and need to be decided by a doctor.
  • Breastfeeding mothers: The photothrity resistance secreted into breast milk is very low. Harm to breastfeeding babies likely does not occur. It is recommended to stop for at least 24 hours after the new contrast scan to re-breastfeed the baby.

Pregnancy

Pregnant women should consult their doctor before taking the drug

2.2 Absolute contrainttraint

  • People with severe dehydration
  • People allergic to iodine

3. Things to keep in mind before, during and after a CT scan with a photocular injection

3.1 Pre-shoot

  • Customers will be checked by doctors for safety issues (check list) before injecting photothrical drugs such as: history of drug allergy, history of asthma, diarrhea, dehydration, diabetes and taking Metformin medication, kidney failure.
  • Renal function examination in which creatinine (eGFR) is required is evaluated before the use of photoretrosive drugs. In some cases such as on-call hemodialysis, emergency kidney injury, or requesting an emergency scan for life-threatening cases (e.g., suspected serious injury, aortic dissection threat) may consider conducting a CT scan with a creatinine.
  • Discontinuation of drugs at risk of poisoning the kidneys in use, pay special attention: nonsteroid anti-inflammatory drugs, diphth dies stop before 24 hours, metformin stops before 48 hours. Drugs that inhibit transfer yeast, receptor inhibition are not required to be strictly discontinued.
  • Guests are required to fast for at least 4 hours before receiving a photocular injection.
  • If the client has a history of drug allergies, asthma, he/she will be prevented from reacting before being taken to the imaging department for contrast injections.

Fasting

Patients need to fast for at least 4 hours before injecting photocsmokers

3.2 During the shoot

  • Guests are calm, breathe gently, are not nervous and are instructed to practice breathing.

3.3 After shooting

  • Guests are monitored at the shooting room or recovery room for at least 30 minutes to see if there is an abnormal reaction.
  • If there are no abnormalities, the client is instructed to return to the clinic.
  • If the patient is inpatient treatment, the doctor will have a follow-up regime in accordance with the patient's current condition.
  • If the patient is outpatient, there are no risk factors, then it is possible to go home. Drink plenty of water, monitor urine volume within 24 hours. If you see less urine than usual, go to the hospital to check your kidney function.
  • Return to the hospital when there are any abnormal signs.
  • Nutrition is the same as other normal days.

4. Why should CT scans be injected with photothrography at Share99 International Health Hub?

  • Before the CT scan, customers will be evaluated by leading medical experts for the medical process, history of themselves and their families and safety checks (check list of CLVT with photo-injections) to ensure the safety of customers before entering the CLVT room.
  • A team of good and professional doctors and technicians at Share99 Health System will help customers trust their expertise, peace of mind and comfort before, during and after the shoot.
  • Modern multi-range CLVT system, which accurately detects even small lesions, newly formed lesions.
