  1. CT Angiography (CTA) Computed tomography angiography (CTA) uses an injection of contrast material into your blood vessels and CT scanning to help diagnose and evaluate blood vessel disease or related conditions, such as aneurysms or blockages. CTA is typically performed in a radiology department or an outpatient imaging center
  2. e blood vessels in the brain, neck, abdomen and chest. Most CTA exams last about 15
  3. CT coronary angiograms are used to diagnose a variety of heart conditions. A coronary CT angiogram is different from a standard coronary angiogram. In the traditional procedure (non- CT angiogram), a flexible tube (catheter) is threaded through your groin or arm to your heart or coronary arteries
  4. The type of CT scan your doctor orders will depend in large part on the area of the body they want to evaluate. Some kinds of CT scan procedures include the following. CT angiography: A doctor might order a CT angiography, or angiogram, if they want to assess a person's risk of heart disease. The scan can also help doctors detect damage to.
  5. CT angiography is performed with the patient lying on her side, donor side buttock up, in the same position that will be used during tissue harvesting for breast reconstruction. The image acquisition parameters are identical to those used at CT angiography of the inferior epigastric arteries and perforating vessels ( Table 2 )

Single-slice CT Machine Multi Slice CT Machines There are several different types of ct machines depending on the amount of slices. Multi-slice scanners come in 4, 6, 8, 16, 32, 40, and 64 slice configurations CT Angiography. Bringing out the information contained in images of CT angiography requires a review using different perspectives (MIP = maximum intensity projection), different reconstruction planes (MPR = multiplanar reconstruction) or a three-dimensional visualization (VRT = volume rendering technique) CT angiography is not suited to exclusion of small intracranial arteriovenous malformations; delineation of the nidus is another domain of digital subtraction angiography, which provides the highest spatial and temporal resolution as well as dynamic information (, 42). In extracranial malformations and hemangiomas, CT can demonstrate both the.

An Angiogram can be used to look at the arteries or veins nearly anywhere in the body, including the head, arms, legs, chest, back, or belly. But there are many different versions or types of angiograms that doctors order for many different reasons CT pulmonary angiogram (technique) The computed tomography pulmonary angiogram ( CTPA / CTPE) is a commonly performed diagnostic examination to exclude pulmonary emboli. Each radiology department will have a slightly different method for achieving the same outcome, i.e. adequate enhancement of the pulmonary trunk and its branches SUMMARY: Multidetector CT (MDCT) angiography is an imaging technique that can provide high-resolution and high-contrast images; however, published reports of MDCT angiography in the evaluation of spinal vascular malformations are limited. We present 2 cases in which MDCT angiography led to diagnosis of a type I (spinal dural arteriovenous fistula) in one and type IVA (perimedullary spinal cord. Less invasive techniques for vascular imaging, such as computed tomographic angiography (CTA), have been developed and have matured in conjunction with developments in catheter arteriography. In a few cases, such as imaging, the aorta and the pulmonary arteries, CTA has supplanted catheter angiography as the gold standard C, CT angiogram of the blood vessels in the brain. Other detailed cross sections can be taken of the brain, vessels of the brain, neck, shoulders, spine, discs, spinal cord, and vessels of the spine. A CT scan can help your doctor diagnose many conditions including: brain damage after a head injur
