Welcome at Mega Scan radiology centers


* Preparation of computerized CT scan on the abdomen and pelvis
1 - abstain from foods that make up the gases the day before the examination such as: vegetables, fruit, soft water, dairy products and eggs.
2 - Allow to eat: pasta, rice, chicken or boiled meat.
3. Gastrografen is taken with 6 cups water as follows:
       The initial dose is 12 hours before the test.
       The second dose is 6 hours before the test.
       The third dose is 3 hours before the test.
4 - Fasting 6 hours before the examination.
5 - Attendance before the date of examination in half an hour.
6 - Bring the previous tests and radiation, if any.

The injected dose in the patient does not pose a risk to the patient's health under normal circumstances. However, there are precautions to be avoided, as in the case of pregnant women, where radioactive material may be a real danger to the fetus, especially in the first months of pregnancy. It should be noted that the patient is the same source of radiation, and this may continue for several hours after the end of the examination (sometimes for 24 hours), in these cases advised not to contact the patient for long periods during those hours, so as not to contact relatives without radiation unnecessarily.

Radiation exposure
During a CT scan, you're briefly exposed to ionizing radiation. The amount of radiation is greater than you would get during a plain X-ray because the CT scan gathers more detailed information. CT scans have not been shown to cause long-term harm, although there may be a very small potential to increase your risk of cancer.
CT scans have many benefits that outweigh this small potential risk. Doctors use the lowest dose of radiation possible to obtain the needed medical information. Also, newer, faster machines and techniques require less radiation than was previously used. Talk with your doctor about the benefits and risks of your CT scan.
Harm to unborn babies
Tell your doctor if you're pregnant. Although the radiation from a CT scan is unlikely to injure your baby, your doctor may recommend another type of exam, such as ultrasound or MRI, to avoid exposing your baby to radiation.
Reactions to contrast material
In certain cases, your doctor may recommend you receive a special dye called a contrast material through a vein in your arm before your CT scan. Although rare, the contrast material can cause medical problems or allergic reactions.
Most reactions are mild and result in a rash or itchiness. In rare instances, an allergic reaction can be serious, even life-threatening. Tell your doctor if you've ever had a reaction to contrast material.

Mammography is a specific type of breast imaging that uses low-dose x-rays to detect cancer early – before women experience symptoms – when it is most treatable.
Tell your doctor about any breast symptoms or problems, prior surgeries, hormone use, whether you have a family or personal history of breast cancer, and if there’s a possibility you are pregnant. If possible, obtain copies of your prior mammograms and make them available to your radiologist on the day of your exam. Leave jewelry at home and wear loose, comfortable clothing. You may be asked to wear a gown. Don’t wear deodorant, talcum powder or lotion under your arms or on your breasts as these may appear on the mammogram and interfere with correct diagnosis.
