CT is an advanced imaging method that uses X-rays to create cross-sectional images of the body. It provides detailed information about tissues, organs, and bone structures.
During the scan, the patient remains still for a short period while images are obtained using X-rays that rotate around the body. The procedure is generally painless and takes only a few minutes.
For some types of CT scans, fasting or drinking a specific amount of fluid may be required. Your doctor will provide you with specific instructions. Metal jewelry should also be removed before the scan.
CT scans use a low dose of X-rays and are generally safe. For pregnant patients or individuals with certain health conditions, your doctor will assess the potential risks and recommend alternative imaging methods if necessary.
Contrast material helps make blood vessels, organs, or lesions appear more clearly. It can be administered orally or intravenously. Its use is generally safe, but caution is required in patients with kidney problems or allergies.
Movement can cause images to become blurry and may make it difficult to make an accurate diagnosis. Therefore, it is very important to remain still throughout the scan.
After the scan, the images are processed by a computer and reviewed by a radiologist. The results are usually provided to your doctor on the same day or within a few days.
While CT uses X-rays, MRI works with magnetic fields and radio waves. CT is faster for imaging bone structures and in emergency situations, whereas MRI is more effective for detailed imaging of soft tissues.
Magnetic Resonance Imaging (MRI) is an advanced imaging method that uses a powerful magnetic field and radio waves to create detailed images of the internal structures of the body. It is commonly used to examine the brain, spine, muscles, joints, and soft tissues.
During an MRI scan, the patient lies on a movable table that slides into the MRI machine and is asked to remain still throughout the scan. The machine uses a magnetic field and radio waves to create cross-sectional images. The procedure is generally painless.
Depending on the area being examined, an MRI scan usually takes between 15 and 45 minutes. In some detailed examinations, the procedure may take a little longer.
During an MRI scan, rhythmic and loud noises may occur due to changes in the magnetic field as the machine operates. These sounds are normal, and patients are usually provided with headphones or earplugs to reduce discomfort.
Most MRI scans do not require any special preparation. However, metal jewelry, watches, credit cards, and other items that may be affected by the magnetic field must be removed. In some cases, your doctor may ask you to fast before the scan.
Since MRI does not use X-rays, it is generally considered a safe imaging method. However, patients with pacemakers, metal implants, or certain prostheses must inform the medical staff before the scan.
In some MRI examinations, contrast material may be used to provide clearer images of blood vessels, tumors, or inflamed tissues. This material is usually administered intravenously and allows the images to be evaluated in greater detail.
MRI images are reviewed and reported by a radiologist after the scan. The results are usually provided to your doctor on the same day or within a few days.
Digital mammography is a modern imaging method that uses X-rays to produce images of breast tissue. It is considered one of the most effective screening methods for the early detection of breast cancer.
Tomosynthesis, also known as 3D mammography, is an advanced imaging technique. It captures multiple images of the breast tissue from different angles, allowing for a more detailed and layered examination.
While digital mammography produces two-dimensional images, tomosynthesis provides three-dimensional cross-sectional images of the breast tissue. This allows for a more detailed evaluation, particularly in individuals with dense breast tissue.
During a mammogram, the breast needs to be compressed briefly. This may cause mild discomfort, but the procedure is generally short and well tolerated.
A digital mammogram is usually completed within 10–15 minutes. When tomosynthesis is used, the procedure may take slightly longer, but it is still relatively quick.
On the day of the examination, it is recommended to avoid using deodorant, powder, or cream, as these products may affect the images. Metal jewelry should also be removed during the examination.
Generally, women over the age of 40 are recommended to undergo regular mammography screening. Depending on individual risk factors, your doctor may recommend starting screening at an earlier age or having it at different intervals.
After the examination, the images are evaluated by a radiologist. The results are usually prepared on the same day or within a short period and then provided to your doctor.
Ultrasonography is an imaging method that uses high-frequency sound waves to produce images of organs and tissues in the body. Since it does not involve radiation, it is considered safe and is widely used in the diagnosis of many conditions.
Color Doppler ultrasonography is a specialized ultrasound method used to evaluate blood flow within blood vessels. Blood flow is displayed in color on the screen, providing important information about vascular blockages or circulation problems.
Ultrasonography is used to examine many areas of the body, including the abdominal organs, thyroid gland, breasts, muscles, and soft tissues. It also plays an important role in pregnancy monitoring and certain interventional procedures.
Color Doppler is particularly used to evaluate vascular diseases, varicose veins, blood vessel blockages, blood clot formation, and blood flow to organs.
During the examination, a special gel is applied to the area being examined, and a device called a probe is moved over the skin to obtain images. The procedure is generally painless and is completed in a short time.
Depending on the area being examined, fasting or having a full bladder may be required in some cases. Your doctor or healthcare professional will provide you with information about the necessary preparation.
Since ultrasonography does not involve radiation, it is considered a safe imaging method. For this reason, it can also be used safely during pregnancy.
The images are usually evaluated immediately during the examination. The radiologist's report is prepared shortly afterward and provided to your doctor.
Digital X-ray is a modern imaging method that uses X-rays to produce images of the internal structures of the body. Compared to conventional X-rays, images are obtained digitally and can be evaluated more quickly.
Digital X-rays are commonly used to evaluate bone fractures, dislocations, lung diseases, joint problems, and certain conditions affecting internal organs.
During the examination, the patient stands or lies in a specific position depending on the area being examined. X-rays are used for a short period, and the images are immediately transferred to the digital system.
A digital X-ray examination is usually completed within a few minutes. Including the preparation process, the procedure is relatively quick.
Most X-ray examinations do not require any special preparation. However, depending on the area being examined, you may be asked to remove metal jewelry, watches, or similar items.
