We provide professional support in tomography.
With the speed provided by the double slice tomography in our hospital, dynamic tomography scans are
performed with and without contrast as well as whole body tomography.
CT (computed tomography) is an X-ray device that can obtain a cross-sectional image from the body. With
CT imaging, many tissues such as lung, liver, kidney, bone, brain, soft tissue
and blood vessels can be displayed clearly. Patients are exposed to a
small amount of radiation during the CT procedure.
IT; It is one of the best methods for examining the chest and abdominal organs. It is the
preferred method in the diagnosis of many diseases including lung, sinuses,
liver and pancreatic diseases. With CT imaging, the guidance of minimally
invasive procedures such as biopsy for diagnosis or treatment can be provided. CT
is a diagnostic method frequently used in bone imaging. It is also used in
the diagnosis of hand, foot, shoulder and other skeletal system structures and
spine bone pathologies. CT is used in the diagnosis of brain, liver,
spleen, kidney and other internal organ injuries by taking advantage of its
ability to perform rapid scanning and provide detailed images in patients with
trauma. CT is also one of the methods used in the diagnosis of vascular
pathologies that may result in stroke, gangrene or renal failure.
Controlled X-rays are passed through the
body. Different tissues absorb X rays at different rates. The data
obtained through the detector are evaluated in computer environment and images
are formed. Multi-detector CT is a newer technique. In this
technique, data is collected faster. The most important advantage of this
system is that many anatomical structures, including small vessels such as
coronary vessels, can be viewed in a short time by rapidly collecting
data. This speed provides a great advantage especially for children and the
elderly, trauma patients and other patients where time is of vital importance.
Contrast material in CT can be administered intravenously (intravenously), orally (orally) or rectally
(rectally), depending on the evaluation to be made. While two or rarely
all three of these methods can be applied together, some patients may not be
given contrast material at all. Before intravenous contrast material is
given, the patient is informed to determine the risk of contrast material
If there is a reaction to the previously used
contrast material, if the person is taking regular medication against any
allergen, or if there is an asthma disease, premedication with antiallergic
drugs may be required. Despite allergies, the first recommended use is
nonionic contrast material. This type of contrast media has a density
characteristic similar to physiological blood. Since the excretion of the
contrast agent used is from the kidneys, the use of contrast agent may be
inconvenient in patients with severe kidney disease.
In this case, your doctor
decides on the use of contrast material or alternative imaging methods are used
after risk assessment is made and solutions are provided to accelerate the
excretion of the contrast agent.
During the intravenous administration of the
contrast agent, a temporary feeling of warmth and a metallic taste in the mouth
may occur. In some cases, there may be a short-term itching sensation. If
itching is prolonged or if there is a rash, these complaints can be eliminated
with medication. Rarely, there may be a sudden swelling of the throat and
difficulty in breathing. You should report this complaint to the
technician who took the shot. These complaints occur very rarely after the
use of nonionic contrast material.
– Whole Abdominal CT Preparation: From the bottles
prepared by a radiology technician in which 40 ml of ionic contrast material is
mixed in 1.5 liters of water, 2 glasses are drunk every 5 minutes. The
last 2 glasses will be drunk by the technician before shooting.
– Upper Abdominal CT Preparation: From the bottles prepared by the radiology
technician in which 30 ml of ionic contrast material is mixed into 1 liter of
water, 2 glasses are drunk every 5 minutes. The last 2 glasses will be
drunk by the technician before shooting.
– Lower Abdominal (Pelvic) CT preparation: The whole abdomen is like CT
preparation. Pelvis CT preparation is started 1.5 hours ago.
– Contrasted water given contains iodine, but it does not cause a significant
side effect since it will not be absorbed in the intestines.
– If contrast material is to be given through the breech, the application is
done in the CT room before the procedure..
