Computed tomography (CT) is a diagnostic imaging technique that uses x-rays to obtain detailed images of the inside of the body. It is also known as computed axial tomography (CAT) because it provides cross-sectional, or "axial," images of the body.

The CT scan process involves the patient being placed on a table that slides into a ring-shaped scanner. During the scan, the machine shines x-ray beams through the body from different angles. Detectors on the other side of the scanner measure the amount of radiation passing through the body, and a computer processes this information to create detailed images of the body's internal structures.

CT scans are used to diagnose and evaluate a variety of medical conditions, including:

Bone injuries and diseases: Detects fractures, bone tumors, arthritis and other bone-related problems.

Lung disorders: Identifies lung diseases such as pneumonia, lung cancer or pulmonary embolisms.

Heart problems: Helps evaluate the presence of heart disease, aneurysms and arterial blockages.

Abdominal disorders: It allows you to visualize organs such as the liver, kidneys, pancreas, spleen and detect problems such as tumors, cysts or stones.

Trauma and internal injuries: Helps evaluate internal damage after an accident or injury.

Brain problems: Detects brain tumors, hemorrhages, injuries and other neurological conditions.

Surgical planning: Used to plan and guide precise surgical interventions.

CT scans provide detailed cross-sectional images, allowing doctors to obtain three-dimensional information about the body's internal structures. Although radiation exposure is an aspect to consider, CT is a valuable tool in the diagnosis and monitoring of various medical conditions.

Computed tomography (CT) scans or computed axial tomography (CAT) scans are usually performed in specialized medical facilities, such as:

Velmar Hospital: Many hospitals, including Velmar Hospital, have CT scan equipment to care for patients in emergency situations and to carry out scheduled examinations.

Radiological clinics and Baja MRI Ensenada: Establishments specialized in diagnostic imaging services, such as radiological clinics and Baja MRI, offer CT services.

Diagnostic Imaging Centers and Baja MRI Ensenada: Some medical centers or clinics, including Velmar Hospital and Baja MRI in Ensenada, are dedicated to performing diagnostic imaging tests, and CT scanning may be one of the available options.

Medical offices: Specialized medical offices, such as Baja MRI, have CT machines in their own facilities to perform specific evaluations related to their field of specialization.

When a CT scan is scheduled, the patient is usually referred by a doctor who determines the need for the test. The patient presents to the appropriate facility, where the procedure is performed under the supervision of Baja MRI staff. It is important to follow staff instructions to properly prepare for the exam, such as refraining from eating or drinking in certain cases and following other specific instructions.

During a computed tomography (CT) scan, the patient is generally expected to remain awake and alert. It is important to follow the instructions of the Baja MRI staff to ensure a successful procedure and obtain high-quality images. Although CT itself does not cause pain, it is essential that the patient remain still and follow the staff's instructions.

In some cases, especially when performing studies of certain parts of the body or in pediatric patients, a mild sedative may be given to help the patient relax and remain still during the test. However, this generally does not involve deep sleep, and it is expected that the patient will be able to respond to the instructions of the Baja MRI staff.

In very specific situations, such as longer neurological studies, imaging procedures may be performed while the patient is under general anesthesia. However, this is less common and is decided on a case-by-case basis.

In summary, in most cases, the patient is expected to remain awake and follow instructions during a CT scan. If you have concerns about comfort or anxiety during the procedure, it is advisable to discuss this with the Baja MRI staff prior to the exam.

After a computed tomography (CT) scan, you can usually resume your normal activities without any special restrictions. However, here are some general considerations that might be helpful:

Hydration: Drink water after the exam, especially if contrast dye was administered. This can help flush the contrast out of your system and reduce any dry mouth sensations.

Food: You can eat normally after the CT scan, unless you have been told otherwise before the exam. Some specific tests may require you to abstain from eating or drinking for a set period of time before the procedure.

Normal activities: In most cases, you can resume your normal activities immediately. CT itself does not usually cause significant side effects that require restrictions after the exam.

Medication: If you take medication regularly, continue taking your medication as directed by your doctor.

Medical follow-up: Depending on the CT results, your doctor may schedule a follow-up appointment to discuss the findings and develop a treatment plan if necessary.

Possible side effects: You may experience some mild side effects, such as hot or cold sensations if contrast dye was used. These side effects are usually temporary and will go away quickly.

Communicating with your doctor: If you experience any unusual symptoms after CT or if you have questions or concerns, it is important to contact your doctor.

Remember to follow the specific instructions provided by the medical or Baja MRI staff who performed the CT scan. If you have any concerns or questions about the test results, do not hesitate to contact your doctor for more information and guidance.

In most cases, during a computed tomography (CT) scan, you will be asked to remove your clothing and change into a hospital gown. This is done to avoid interference of clothing with the images and ensure the quality of the results. Additionally, metallic objects such as buckles, buttons, jewelry, and piercings can affect the quality of the images, so you will be asked to remove these items as well.

You may be provided with a gown to cover you and maintain your privacy during the procedure. It is important to follow the instructions of the Baja MRI staff to ensure that the procedure is performed efficiently and that the images are as clear and accurate as possible.

If the specific area being examined requires the administration of contrast dye, you may also be asked to remove any objects that may interfere with that specific area. In some cases, you may be asked to remove certain items, such as earrings or dentures, depending on the part of the body being examined.

Remember that the Baja MRI staff is trained to ensure your comfort and privacy during the procedure. If you have any concerns or questions about the process, please do not hesitate to contact us before the exam.

A brain computed tomography (CT or CAT scan) is a medical imaging study that provides detailed images of the internal structure of the brain. This test can show various brain characteristics and conditions. Some of the aspects that can be seen on a brain CT or CT scan include:

General anatomy of the brain: CT or CAT scan provides detailed images of the brain anatomy, allowing you to see the main structures such as the brain lobes, the cerebellum and the brain stem.

Brain tumors: CT or CAT scan is effective in identifying the presence and location of brain tumors, whether benign or malignant.

Hemorrhages: It can detect intracranial hemorrhages, such as subarachnoid hemorrhages or intraparenchymal hemorrhages, which are accumulations of blood in different areas of the brain.

Cerebrovascular accidents (CVA): It allows you to identify signs of ischemic or hemorrhagic strokes by visualizing affected areas of the brain.

Traumatic injuries: CT or CT is useful to evaluate brain injuries caused by trauma, such as contusions, hematomas or skull fractures.

Infections: May show signs of brain infections, such as abscesses or meningitis.

Hydrocephalus: Abnormal accumulation of cerebrospinal fluid in the brain can be visualized on a CT or CT scan.

Malformations and anomalies: It can detect congenital brain malformations or abnormalities in brain structure.

Vascular problems: Vascular anomalies, such as aneurysms or arteriovenous malformations, may be identified.

Assess degenerative changes: It can provide information about degenerative changes in the brain associated with diseases such as Alzheimer's disease.

It is important to note that the interpretation of images from a brain CT or CT scan should be performed by a radiologist or neuroradiologist, and the final result will be discussed with your doctor to obtain an accurate diagnosis and develop an appropriate treatment plan, if necessary. .

The frequency with which a computed tomography (CT or CAT) scan may be performed depends on each patient's specific medical need and the risks associated with radiation exposure. The radiation used in CT can have cumulative effects on the body over time, so healthcare professionals try to limit unnecessary exposure.

In general, the principle of using medical imaging tests, such as CT or CT, is followed only when they are medically necessary for diagnosis or treatment monitoring. The decision to perform a CT or CAT scan is based on the doctor's assessment of the risks and benefits, taking into account the available clinical information.

In cases of chronic diseases or long-term follow-up, healthcare professionals may choose to use other imaging modalities, such as magnetic resonance imaging (MRI) or ultrasound, that do not involve ionizing radiation, as long as they provide the necessary medical information.

If a patient requires multiple CT scans in a short period of time, the medical team will carefully evaluate the need for each exam and take steps to minimize radiation exposure whenever possible.

It is important for patients to discuss with their doctors the risks and benefits of any medical imaging procedure, including CT or CT, and to provide information about any previous examinations they have had at the same or different medical centers. Open collaboration between the patient and the medical team ensures informed and conscious decision-making.

For a contrast-enhanced computed tomography (CT) scan, a radiopaque contrast medium is used to highlight certain structures or fluids in the body, making them more visible in the images. The contrast medium most commonly used in CT scans is iodide, in the form of sodium iodide or meglumine iodide.

Contrast dye is usually given through a vein (intravenous) by injection. Prior to contrast administration, Baja MRI or medical staff will ask you if you are allergic to iodine or radiopaque contrast media and will perform the necessary evaluations to ensure it is safe for you to receive contrast.

This contrast medium can improve the visibility of certain structures and make it easier to detect abnormalities, such as tumors, blood vessels, and injured tissues. After the contrast injection, you may feel a warm or metallic sensation in your mouth, but this is normal and usually temporary.

It is important to tell medical staff if you have a history of allergies, kidney problems, or other health problems, as it could affect the decision to use contrast dye or require additional precautions.

Remember to follow the specific preparation instructions provided by the medical or Baja MRI staff before the procedure, and do not hesitate to ask questions if you have any concerns or questions about contrast administration.

In some cases, patients may be instructed to refrain from drinking water before a computed tomography (CT) or computed axial tomography (CAT) scan in order to obtain clearer, more detailed images of certain areas of the body. The main reason behind this recommendation is to minimize the presence of fluid in the area being examined and improve the quality of the images. Below are some reasons why this instruction may be given:

Artifact reduction: Artifacts on CT images can occur due to the presence of fluid, especially when examining abdominal or pelvic areas. Drinking water before the exam could increase the amount of fluid in the stomach or intestines, creating artifacts and making the images difficult to interpret.

Improved visualization: By minimizing the presence of fluid, internal organs and structures can be more clearly visualized on CT, helping to obtain sharper and more precise images.

It is important to follow specific instructions provided by the medical or Baja MRI staff prior to the procedure. In some cases, temporary fasting may be required before CT, which includes abstaining from food or drink for a specific period of time. This is done to ensure optimal conditions during the exam and obtain quality results.

If you have questions or concerns about CT preparation instructions, I recommend contacting the medical or Baja MRI staff who will be performing the exam. They will be able to provide you with detailed information and ensure that you follow the necessary instructions to obtain the best possible results.
