The time it takes to receive CT scan results can vary depending on the urgency of the situation. In some cases, results may be available immediately after the scan is completed. In others, it may take a few hours or even a few days. It's best to check with the relevant healthcare providers performing the investigation for a more accurate estimate of when results will be available.

You may bring someone to accompany you into the scanner room, and eveColonoscopy is the preferred method of identifying colon cancer. CT scans, on the other hand, may offer your healthcare professional crucial additional information about the spread of cancer to neighbouring or distant structures, which will be useful in identifying the best possible mode of treatment. n hold your hand during the scan. The companion will need to complete an MRI safety questionnaire to ensure that it is safe for them to be in the room.

Before undergoing certain types of CT scans, it is advised to fast for several hours. Particularly when the area being examined involves the digestive system in order to improve the clarity of generated images. Occasionally, following the administration of contrast, patients may develop allergic reactions. The severity of these allergic reactions may vary from person to person, where some may develop mild itchiness, and some may require emergency care with resuscitation. However, following an emergency with a patient's life at risk, immediate results of these tests may urgently be needed, in such instances, completion of fasting may not be required.

Wearing relaxed, easily removable clothing is advised because you could be requested to change into a gown for your CT scan. To reduce interference with the quality of the generated images, necklaces, earrings, and other jewellery must be removed before the exam.

A concussion is a temporary disruption of brain function that occurs after a minor trauma and typically does not require imaging for diagnosis. However, in some cases, severe traumatic brain injuries can resemble concussion symptoms and may require brain imaging (CT scan of the brain) to identify the presence of potential intracranial bleeding

CT scans are commonly used to visualise hard structures (e.g. bones) and detect the presence of bleeding, whereas MRI scans are used to visualise internal organs and structures containing soft tissues (e.g. muscles, ligaments etc.). In certain instances, these imaging methods may be used together to obtain a more complete and accurate picture of the patient's illness. This helps medical professionals better understand a patient's condition and determine how best to treat them.

Although CT scans of the heart aren't usually meant to show the lungs or other nearby structures, they may sometimes uncover coexisting problems in these neighbouring organs. Lung nodules are the most frequent incidental finding on cardiac CT scans, which may suggest the possibility of lung cancer.

CT scans and X-rays are medical imaging techniques that use ionizing radiation to visualize internal body structures. CT scans offer higher resolution and differentiate between tissues, while X-rays provide a quick overview of bones and organs. X-rays are simpler and quicker to perform, often available in healthcare settings, while CT scans require more time and expertise. The choice between these techniques depends on the clinical situation, balancing detailed information with radiation exposure and convenience.

MRI scans are regarded as a valuable tool for medical professionals due to its capability to provide detailed information about the internal structures and organs within the human body. Primarily, these scans are performed to visualise soft tissue structures such as muscles, tendons, ligaments and internal organs. In addition, with the help of different imaging protocols, MRI scans are capable of performing a comprehensive assessment of diseases such as cancers, brain disorders, spinal abnormalities, heart diseases, and blood vessels. They are also helpful in identifying inflammation and infection within any internal organ or soft tissue structure, making it a highly valuable non-invasive investigation.
