ct scan centre in Delhi

 It is a commonly used diagnostic intervention to visualize the hard tissues of the body. It is a radiological imaging technique performed by radiologists that provides a combination of a series of X-ray images of the body.which are further processed by computer-aided devices to create cross-sectional images of bones and soft tissues in the body. It is a very comprehensive assessment that helps healthcare professionals make an accurate diagnosis of the disease.

It is mostly used by doctors for cancer screening, staging and follow-up. CT scans are also popular for use as an aid during biopsy and surgical procedures.

Types of CT Scan

High-resolution CT scan): This scan has high resolution and a high level of imaging accuracy. It is mostly used to diagnose lung diseases.

Helical or spiral CT scan): This type of scan is recommended to diagnose heart and cardiovascular diseases. In this type of scan, the X-ray beam sweeps across the organ from different angles and provides detailed images. Calcium deposits within the coronary arteries can be assessed with this scan.

Ultrafast CT scan (electron beam CT scan): This type of CT scan creates images that move quickly, helping to visualize a "film". It helps to study the chambers and valves of the heart. This scan is also used to check the condition of the heart. This is the most commonly used scanning method.

Computed tomographic angiography scan (commonly called a CTA scan): Angiography, also known as arteriography, provides detailed pictures of the blood vessels.

Combined positron emission tomography and CT (PET/CT scan): This is a combination of CT and positron emission tomography techniques and is usually called PET/CT. This combined technology provides detailed anatomy and also determines cell function and metabolism which is a very important tool for cancer diagnosis and treatment. This pairing technique is also used to screen for conditions such as epilepsy.

Points to remember before you are considering a CT scan

Exposure to Radiation - A CT scan is similar to an X-ray in that the patient is exposed to harmful ionizing radiation. But the amount of radiation is much higher than basic X-ray exposure because CT takes many detailed pictures to provide a clear picture. Various studies have shown that the very low doses of ionizing radiation used in CT scans lead to long-term effects, and that exposure to higher doses can significantly increase the potential risk of cancer).These potential disadvantages of CT scanning are overlooked because there are factors that may be beneficial in early disease detection. Therefore, radiologists use the best doses of radiation to obtain the detailed reports required for the study. Technological advances are also helping to develop new CT scan machines that require less radiation.

Pregnant and Breastfeeding Women - The ionizing radiation used by CT scanning has not been proven to be harmful to the unborn fetus, but CT scanning is not recommended for pregnant patients. Therefore, the radiologist confirms whether the female patient is pregnant or not before the test to do.For women who are breastfeeding, barium used for irradiation is not expected to enter the bloodstream and is unlikely to become part of the breast milk. Although it has been noted that less than 1% of solutions based on iodine can enter breast milk. This is unlikely to have any adverse effects on the baby, but radiologists still advise mothers to avoid breastfeeding for 24 to 48 hours after a CT test.

Considerations in Children

The adverse effects of CT scanning on children are evaluated and various guidelines are prescribed. These guidelines include:

In children a CT scan is only done when there is no other option

Ultrasound and MRI techniques are preferred

The radiation level is adjusted based on the child's weight

The size of the scanning area is small

Scan resolution is also used if high resolution images are not required
