CTA is a CT scan to visualize the arterial and venous blood vessels of a specific part of the body. This can be used to study arteries feeding the brain to those delivering blood to the lungs, abdominal organs, and extremities. CTA is also used to study the coronary blood vessels of the heart. CTA scans always require IV contrast to enhance the blood vessels to make them undoubtedly distinguishable from surrounding anatomy.
The flow of contrast through the vessels helps reveal areas of narrowing stenosis and blockages occlusions. For more information on CT scans including contrast please visit the CT section.
If the exam is ordered without contrast, little or no preparation such as fasting may be required specific to your exam. If your exam does require preparation instructions you will be contacted 24 hours prior to your exam and given exam specific preparation instructions. If the test is ordered with IV contrast by your physician you will be required to receive a contrast injection into a vein in your arm. The technologist may ask if you have asthma or if you have allergies to Iodine and certain drugs.
The IV contrast material used at Unique Imaging for CT is nonionic iodine and is less likely to cause an allergic reaction than standard iodine contrast.
You will be asked not to consume food 4 hours prior your exam to avoid complications during the rare event of an anaphylactic contrast reaction. In addition, patients 60 years or older require a blood test for renal Kidney functions.
You may be asked to wear a gown during the exam or you may be allowed to wear your own clothing if it is loose-fitting and has no metal fasteners. The technologist will provide a secure locker to place all your belongings as no foreign objects are allowed in the CT suite for your own safety.

Your position on the table depends on the body part being scanned, but a majority of the time you will be asked to lie on your back, with your head on a cushion, with your feet pointing toward the scanner.
If you are to receive contrast, the technologist will then start an IV. Once it is in place, they will then take preliminary scans of the area in question. These are called scout images and are used to map the area for testing. During this, you will feel the table move, but you will not be touched.
The scanner will, with recorded messages, ask you to take a breath before each scan, and hold it for the duration of the scan normally seconds. For some patients, even this small amount of time is extremely difficult. This is understandable and we will not ask more than you are capable of.
Once the technologist completes the scout images, he or she will proceed with the primary exam. If contrast is to be given, it will then be administered through your IV with either a pressure injector or pushed by hand with a syringe, depending on the test.
In some patients, the actual injection can be associated with a sensation of warmth, heat or flushing. These feelings are transient and typically pass quickly after the injection. Images will then be obtained. The table will once again move, with the only difference being a slightly longer scan time. It is important that during this scanning you remain as still as possible so that the scanner may get the best possible images.
The format of each module will be 12 short-form questions, worth five marks each. These will be a mixture of computational and written questions with no question choice. Students tend to take up to two years to complete the CTA qualification, but this depends entirely on your preferred way of learning and study pathways chosen. You must register with CIOT as a student at least four months in advance of taking your first exam.
All study methods include online and printed materials. These differ depending on which study method you choose. The Study Manuals cover the syllabus for each course and are the key source of your learning material. The Question Banks are designed to test your understanding of the fundamental principles covered in each chapter in the corresponding Study Manual.
These detail the core areas of the syllabus which will be covered during the Classroom and Live Online courses, incorporating worked examples. The pre-revision question bank contains more challenging questions for you to consolidate your knowledge of the full syllabus for each paper.
The revision question bank contains exam standard questions and recent past papers all with answers updated to the relevant Finance Act , providing excellent final preparation for the exam.
The memory joggers contain short summaries of the key rules covered in each chapter of the study manuals and also include any useful proformas.

For children and for adults of reproductive age, radiologists administer low radiation dose CT scans with dose reduction measures. CT exams are generally painless, fast, and easy. Multidetector CT reduces the amount of time that the patient needs to lie still. Though the scan is painless, you may have some discomfort from remaining still for several minutes or from placement of an IV.
If you have a hard time staying still, are very nervous, anxious, or in pain, you may find a CT exam stressful. The technologist or nurse, under the direction of a doctor, may offer you some medication to help you tolerate the CT exam. If the exam uses iodinated contrast material, your doctor will screen you for chronic or acute kidney disease. The doctor may administer contrast material intravenously by vein , so you will feel a pin prick when the nurse inserts the needle into your vein.
You may feel warm or flushed as the contrast is injected. You also may have a metallic taste in your mouth. This will pass. You may feel a need to urinate. However, these are only side effects of the contrast injection, and they subside quickly. When you enter the CT scanner, you may see special light lines projected onto your body. These lines help ensure that you are in the correct position on the exam table. With modern CT scanners, you may hear slight buzzing, clicking and whirring sounds.
These occur as the CT scanner's internal parts, not usually visible to you, revolve around you during the imaging process. You will be alone in the exam room during the CT scan, unless there are special circumstances. For example, sometimes a parent wearing a lead shield may stay in the room with their child. However, the technologist will always be able to see, hear and speak with you through a built-in intercom system. After a CT exam, the technologist will remove your intravenous line.
They will cover the tiny hole made by the needle with a small dressing. You can return to your normal activities immediately. A radiologist , a doctor specially trained to supervise and interpret radiology exams, will analyze the images. The radiologist will send an official report to the doctor who ordered the exam. You may need a follow-up exam. If so, your doctor will explain why. Sometimes a follow-up exam further evaluates a potential issue with more views or a special imaging technique.
It may also see if there has been any change in an issue over time. Follow-up exams are often the best way to see if treatment is working or if a problem needs attention. Doctors take special care during x-ray exams to use the lowest radiation dose possible while producing the best images for evaluation.
National and international radiology protection organizations continually review and update the technique standards radiology professionals use. Modern x-ray systems minimize stray scatter radiation by using controlled x-ray beams and dose control methods. This ensures that the areas of your body not being imaged receive minimal radiation exposure.
Every effort will be made to reduce radiation while performing CT angiography, including tailoring the scan parameters specific to your body type. The scanning area will also be limited to the organ of interest to avoid unnecessary radiation to other body parts. A person who is very large may not fit into the opening of a conventional CT scanner. Or, they may be over the weight limit—usually pounds—for the moving table. It is not advised to administer iodinated contrast material in patients with impaired renal function or who previously exhibited a severe allergic reaction to contrast material.
