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

What's safer: coronary angiogram or CT angiogram?

What's safer: coronary angiogram or CT angiogram?

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

Could duplex ultrasound replace arteriography in screening for mesenteric ischemia?

Could duplex ultrasound replace arteriography in screening for mesenteric ischemia?

No screening: There is nothing called screening for mesenteric stenosis. If you have no symptoms then you no need to screen for occlusion. If you have chronic symptoms then duplex ultrasound is a good starting test but has a lot of limitations. In cases of acute ischemia then ct scan is best to start with. ...Read more

Does angiogram show heart coronary arteries blockage?

Does angiogram show heart coronary arteries blockage?

Yes: Yes, a coronary angiogram is the most widely used test to look for blockages in the arteries of the heart and to decide the best treatment option (medication only vs stent vs bypass surgery). ...Read more

Carotid mra vs carotid doppler ultrasound better predictor?

Carotid mra vs carotid doppler ultrasound better predictor?

Doppler Ultrasound: Ultrasound has proven to be cost-effective and quite accurate in determining the degree of narrowing in the carotid artery. Many vascular surgeons, including myself, solely rely on it to decide whether someone needs an operation. Mra is not so good and over-estimates the actual degree of narrowing. I would not rely on its findings to decide on operating. As mentioned a cta is much better. ...Read more

Is coronary CT angiogram more reliable than invasive coronary angiogram?

Is coronary CT angiogram more reliable than invasive coronary angiogram?

No : Each of these tests has its advantages and disadvantages. But coronary angiogram (cardiac cath) is still the most reliable way to look at coronary arteries. ...Read more

Can angio cardiac CT detect angina?

Can angio cardiac CT detect angina?

No: Angina is a clinical symptom. The angiogram r cardiac ct are both imaging studies. We can look at imaging studies and suggest that there is narrowing of the coronary arteries which may cause angina. ...Read more

Carotid artery disease, different results from duplex ultrasound vs. Ct angiogram (cta), is that possible?

Carotid artery disease, different results from duplex ultrasound vs. Ct angiogram (cta), is that possible?

Results: Because these are two different imaging modalities, it is possible to get divergent results. Generally however these two studies show congruent data. ...Read more

Coronary Angiography report concluded;"atherosclerotic coronary artery disease showing moderate proximal LAD mixed stenotic lesion 50%"what it means?

Coronary Angiography report concluded;"atherosclerotic coronary artery disease showing moderate proximal LAD mixed stenotic lesion 50%"what it means?

Test Result: I find it is best to discuss any test result with the physician who did the test or ordered the test. They can interpret it knowing all the clinical history involved and tell you exactly what is going on. ...Read more

Does coronary CT scan w/calcium score rule out coronary artery disease/atherosclerosis?

Does coronary CT scan w/calcium score rule out coronary artery disease/atherosclerosis?

Coronary CT: Calcium score CT doesn't rule out atherosclerosis or chance of heart attack. With that said the more calcium the more volume of plaque both calcified and noncalcified. The test can help when the need for drug therapy isn't clear. ...Read more

Carotid doppler showed 50% bilateral blockage, mr angiogram was negative. Which is more accurate?

Carotid doppler showed 50% bilateral blockage, mr angiogram was negative. Which is more accurate?

Debatable: Few vascular surgeons make decisions on carotid artery stenosis based on mr, as carotid doppler (ultrasound) has been proven to be very reliable when a good technologist performs the study. From what you're describing, your carotid arteries are likely without disease as the reporting standards for ultrasound haven't quite been set. In my lab you'd likely be found to have no disease at all. ...Read more

What is mesenteric ischemia?

What is mesenteric ischemia?

Intestinal angina.: Mesenteric ischemia occurs when the blood supply to the intestine is insufficient to maintain it's normal function. When acute, it may lead to infarction of the intestine, which is life-threatening. When chronic, it may cause a nagging intense pain after eating, analogous to angina. ...Read more

Carotid artery disease, what to believe, if different results from duplex ultrasound vs. Ct angiogram (cta)?

CTA better: Although cta is more accurate but it also depends on image quality done by radiology . If there is two conflicting studies of the carotid artery , then you should get the gold standard conventional arteriography if clinically indicated. ...Read more

Does an echo detect coronary artery disease?

Does an echo detect coronary artery disease?

May be: Echocardiograms are very good at seeing the function of the heart muscle. If coronary artery disease has damaged the heart, the weekend part of the heart will be visible on an echocardiogram. However, significant blockage can occur without damage. A resting echocardiogram will not be able to see this. A stress echocardiogram, however, may be effective in detecting this type of disease. ...Read more

What causes mesenteric arterial thrombosis?

What causes mesenteric arterial thrombosis?

3 major factors: Condition of the artery (caliber, plaque, injury, inflammation...) viscosity of the blood (hydration, tobacco, blood element derangement...) and the force of the blood flow (stasis, poor heart functions...) are the main factors leading to mesentary arterial thrombosis. It can happen in association to an embolic event. ...Read more
