Whats safer: coronary angiogram or CT angiogram?

Whats safer: coronary angiogram or CT angiogram?

Ct vs cath: In simplest terms the ct angiogram would be safer than a coronary angiogram, however, they are usually used in different circumstances. The ct angiogram is useful as a screening tool to see if coronary disease is present. A cardiac catheterization is performed when a patient has an acute coronary syndrome or a myocardial infarction to evaluate coronary disease, or even treated. ...Read more

Computed Tomography (Definition)

Ct uses xrays taken an 360 degrees combined with a computer to see"inside" the body. The table moves as the xray tube and detectors spin around the patient 10 times a second or more! the image shows excellent soft tissue detail, enhanced with injection of intravenous contrast or oral contrast. This way the body is shown in slices, in any plane, usually axially, but ...Read more

Can computed tomography angiography show heart problems right?

Can computed tomography angiography show heart problems right?

It depends: On regular contrast-enhanced ct exams, cardiac abnormalities including masses or thrombus can be detected, but little information regarding the coronary arteries can be obtained. On a dedicated coronary ct exam with contrast (ekg gated), the coronary arteries can be evaluated for narrowing or blockages. This is usually not possible on regular ct exams due to motion. ...Read more

Is computed tomography angiogram cta a very common procedure?

Is computed tomography angiogram cta a very common procedure?

CT angiogram: It is being done much more often when it is necessary to visualize blood vessels (for example to see if there's a blockage). There is some radiation involved but it is considered much less "invasive" and has less complications than the regular type of "angiogram", where blood vessels are visualized by inserting thin tubes called catheters directly into them to inject a dye. ...Read more

Ct scan, mri, nuclear medicine imaging, ivp scan, how are they different?

Quite different: Ct involves xray type radiation with cross sectional imaging in transaxial, sagittal, and coronal projections. Nuclear medicine, internal irradiation either injected intravenously, inhaled, ingested, injected subcutaneously.Ivp uses injection of contrast material for visualization of kidneys and bladder with x-ray. Mr imaging uses no ionizing radiation magnetic fields to generate x-sectional images. ...Read more

Ct coronary angiogram takes pictures of what parts?

Arteries: A ct angiogram takes pictures of the coronary, or heart, arteries. It also gives information of the remaining cardiac structures. The main pumping chambers, or ventricles, the heart muscle walls and some information regarding the heart valves as well. If there are bypass grafts from previous surgeries, these can often be visualized as well. ...Read more

Is CT angiography good or bad?

A tool: Ct angiography is a useful tool when used where needed ( to diagnose a blood clot in the lung, for example). It can cause harm if there is a reaction to the contrast or if rather kidneys are fragile, so each time it is ordered the risks should be weighed against the information to be gained. ...Read more

Had a CT angiography done on the first and still no word of my results should I be worried?

Worried about what?: This is a subspecialty examination and it could be that the person who does such work was not available at the imaging site. If you haven't heard byt today though, i would suggest calling the radiology facility to get a copy of your report sent to your doctor. You should discuss your report with the doctor rather than interpreting it yourself. ...Read more

Ct angiography offered. Terrified of dieing from allergic reaction to the dye. 22 male.

Allergy: If you have not previously reacted to dye the chances of your doing so are not great, and since you are in a facility trained to deal with such reactions dying from dye is very unlikely. You might want to discuss this with the radiologist in charge. If still concerned see a psychiatrist or clinical psychologist and address your fears. Good luck. ...Read more

Medication?: Stress can cause higher blood sugars in patients with dm. However, if you were asked to fast for the test therefore cut back on your medication this could also cause higher blood sugars temporarily. If you're on metformin some centers will ask patients to wait a couple of days before restarting depending on the type of IV contrast used. ...Read more

Disc herniation?: These symptoms suggest that a nerve could be pinched in the cervical spine. A cta may not cover the suspected area. A MRI of the cervical spine would be useful. However, at your age and with those symptome, if confirmed, the most likely recommendation for a disc herniation would be to do nothing unless things worsen, i.e. Weakness and pain. ...Read more

Bronchial calcium: My 84 GM had CT angio and tracheobronchial calcifications noted. What's meaning? ANS: your GM is old and calcification increases with age. Assuming she has no other problems. If her coronary arteries were normal she will never die of CAD. Congratulate her & thank her 4 giving u good genes & showing u how to live right 4 ur genes.

Shift to BetterFocus: Neither stress tests (all methods) or angiograms identify arterial disease until very advanced. High quality ct ca scoring can detect calcium in heart arteries by mid 30's. Yet known for >8 decades that artery disease typically begins later childhood. Thus focus on driving factors: (a) lipoproteins (not cholesterol; wrong issue), (b) blood glucose by hba1c <5.0% (c) systolic BP <120 mmhg. ...Read more
