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

Angiography (Definition)

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

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

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

Nuclear stress test and cardiac coronary CT angiogram, which do you recommend?

Nuclear stress test and cardiac coronary CT angiogram, which do you recommend?

Depends on situation: Nuclear stress test involves looking at perfusion of heart for defective areas representing coronary artery disease looking for areas of permanent damage versus areas that are reversible possible related to area of coronary narrowing. Coronary ct angiogram looks at anatomy of coronary arteries looking for areas of narrowing and blockage.Answer depends on information physician needs and insurance. ...Read more

Best non invasive test to check coronary arteries? Ct angio, stress echo and cardiac MRI MRA? Any better non invasive testing to check coronary art?

Best non invasive test to check coronary arteries? Ct angio, stress echo and cardiac MRI MRA? Any better non invasive testing to check coronary art?

Tests: Each of the tests listed has specific strengths and weaknesses. The choice of study depends on the specific information desired by the ordering physician and the capabilities of the performing laboratory. CT angio in many cases will produce the best images of the arteries of the three, MRA has its specific indications and stress echo doesn't show the vessels but shows the effects of serious ischem ...Read more

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

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

Is it safe to smoke after a myocardial perfusion scan thallium scan cardiac nuclear imaging?

Is it safe to smoke after a myocardial perfusion scan thallium scan cardiac nuclear imaging?

Well...: Since you had a cardiac nuclear scan, I assume your doctors were looking for coronary artery disease. You seem to be a smoker, which makes artery disease worse. So smoking is not a good thing for you, and you should try to stop. Having said that, you are probably not in any more immediate risk for heart problem for smoking after the nuclear exam. Long term risks are greater with smoking. ...Read more

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

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

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

Spect images demonstrate inferior and apical reversibility from my nuclear stress test. Is a cardiac catherization must be done?

Spect images demonstrate inferior and apical reversibility from my nuclear stress test. Is a cardiac catherization must be done?

Not enough data...: Inferior ; apical reversibility means there is some ischemia in those regions. Without seeing the images it is difficult to tell how much. If there is very mild ischemia, some cardiologists may decide to do medical management (only medicines). If there is any significant amount of ischemia, cardiac catheterization is usually done. Again, it depends on the clinical scenario..Not enough data. ...Read more

Could computed tomography angiography show heart problems?

Could computed tomography angiography show heart problems?

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

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

What blood tests will detect coronary heart disease/ heart artery build up? Any tests? Would the d dimer test show?

What blood tests will detect coronary heart disease/ heart artery build up? Any tests? Would the d dimer test show?

No lab tests: Coronary artery disease is mainly diagnosed by assessing one's. Cardiovascular risk as well as sorting out various symptoms. Lab tests to help here would be a full lipid panel as well as a CRP which is a marker of inflammation. These do not detect plaque but do help i risk analysis. D-dimmer is used for venous disease ie blood clots in legs or lungs. ...Read more
