Ct Angiography Risks
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 moreSee 1 more doctor answer
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
Both safe: Both also have risks such as radiation and contrast usage. Coronary arteriography has small bleeding risk at puncture site. Need to get the right test for your problem. Coronary arteriography is the gold standard. ...Read more
How many cardiac cta (computed tomography angiogram) procedures are performed annually in small hospitals?
CTA: Cardiac computed tomographic angiograpy is performed to try and diagnose cardiac anatomy and pathology. It doesn't diagnose everything but can provide very useful information that often yield a diagnosis if the study is ordered appropriately. ...Read more
Not usually: Not usually nuclear medicine affecting ct but the opposite. However ct scan with intravenous iodine contrast materials can affect thyroid scans and thyroid uptake. Renal GFR studies using glofil with i125 are also affected by iodine contrast of ct. ...Read moreSee 2 more doctor answers
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 moreSee 1 more doctor answer
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 moreSee 2 more doctor answers
Carotid artery disease, different results from duplex ultrasound vs. Ct angiogram (cta), is that possible?
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
No: Iv contrast is often not used when the ct is for the purpose of looking for renal stones and in people with a history of contrast allergy or renal disease. It is often helpful in assessing persons with nonspecific abdominal symptoms as it will better show areas of inflammation, infection, and tumor. ...Read moreSee 1 more doctor answer
What are advantages of MRT (Magnetic Resonance Tomography) scan over MRI (Magnetic Resonance Imaging) scan? Are these equally safe?
What are the differences of getting CT angiography vs. Mra for ascending thoracic aortic aneurysm?
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 moreSee 1 more doctor answer
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 moreSee 2 more doctor answers
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 moreSee 1 more doctor answer

I had a CT angiography done and i wanted to know how long does it take for the results to go to the office?
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
Had my CT angiography today and my sugar is a little high is that normal in diabetics from the contrast?
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 moreSee 1 more doctor answer
Left arm tingly, burning, i feel shaky nauseous had a CT angiography everything came out fine what can it be?
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 moreSee 1 more doctor answer
I've been drinking alkaline water even after my CT angiography today and i've been sweating a lot is that normal?
My grandmother is 84years old, she did CT angiography in heart,the result was tracheobronchial tree calcifications,what's meaning?
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. Listen to her genes as they sing you a song of long life. ...Read more
Had a stress test done dec 15th 10%false positive on it. At the hospital cardio doc said CT angiography now he says no. Can i get one without a docto. Referral because I have been left with the doubt?
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 moreSee 2 more doctor answers
Short of breath when i walk around have had numerous heart tests all come out good what can it be? Last heart test was a CT angiography it was good
Could be lungs: Look beyond your heart for shortness of breath. Consider pulmonary function tests as a screen for intrinsic lung disease. Visit with your primary care provider and check other laboratory tests. A pulmonologist (lung specialist physician) consult may also be helpful. Have you seen a cardiologist as well? ...Read more
No: Echocardiography is cheaper, has no radiation, and is accurate. I routinely follow patients with thoracic aortic aneurysms with annual echos. ...Read more
encompasses several medical imaging tests that visualize the anatomy and pathology of blood vessels. Standard angiography involves catheterizing a vessel and injecting contrast under X-ray visualization. Less invasive angiographic techniques include MR angiography ...Read more
