Cardiac Ct Scan (Overview)

Chest ct for calcium count is unfortunately not paid for by most insurance companies, but is underutilized and can be quite valuable in determining value of statins and identifying patients at risk for coronary events.

Do I need to worry about sca with a normal cardiac workup (ekg, echo, stress, chest xray and CT scan)? Blood work overall normal, scared/high anxiety?!

Do I need to worry about sca with a normal cardiac workup (ekg, echo, stress, chest xray and CT scan)? Blood work overall normal, scared/high anxiety?!

Probably not: A sudden cardiac arrest (sca) is a rare phenomenon. It almost always occurs in patients who have cardiac disease: either electrical, mechanical, or related to a heart attack. It sounds as though all of your testing has been normal. This should provide some relief from your anxiety. ...Read more

Can 265 slice cardiac CT scan with and without contrast miss a CAD? And how accurate are?

Can 265 slice cardiac CT scan with and without contrast miss a CAD? And how accurate are?

Generally very: Cardiac ct angiography is a very accurate test for coronary artery disease but it requires meticulous technique and highly skilled radiologists specialized in interpretation. Additionally, the patient's heart rate should be regular and relatively slow. It is considerably more challenging to do well than a routine ct scan. ...Read more

Can a cardiac ct scan show soft plaque in heart?

Can a cardiac ct scan show soft plaque in heart?

I don't believe it c: Cardiac CT scan mainly shows calcium deposits which are only present in a mature plaque. So a soft plaque is not visible in the coronary arteries (that is where they locate themselves, not in the heart itself). ...Read more

How slow does your heart rate have to be for a cardiac ct scan?

How slow does your heart rate have to be for a cardiac ct scan?

It depends on the: Scanner. If it is 64 slice scanner, HR should be 65 or less. The slower the heart rate, the better the pictures. Docs use beta blocker meds to decrease the heart rate. I give 25-100 mg as needed. If someone's HR is over 90 before going for scan (before the meds), it can be hard to get HR down. If it is a high speed scanner, HR could be faster.

How low does you heart rate need to be for a cardiac ct scan? Mine was 64-70 but still did the scan even tho they said they wanted it under 60.

How low does you heart rate need to be for a cardiac ct scan? Mine was 64-70 but still did the scan even tho they said they wanted it under 60.

The higher: The heart rate, the higher the chance for cardiac motion artifact that will decrease the accuracy of the scan. Even though 60 or below is the target, a heart rate slightly above 60 is probably fine. The chance of motion artifact starts to significantly increase beyond 70. ...Read more

Cardiac ct scan results dr said pictures weren't very good. Wants me to get a nuclear stress test. Would it be feasible to ask for another CT scan?

Cardiac ct scan results dr said pictures weren't very good. Wants me to get a nuclear stress test. Would it be feasible to ask for another CT scan?

Unadvised but possib: Getting another CT scan is 99% likely to give the same picture as the 1st, barring an obvious problem (like the machine broke down, which they would have informed you at the site). Another modality is more likely to provide information than repeating the same test. CT scans involve lots of radiation, & show calcium deposits & perhaps blood flow, but not if heart is affected. The Nuc stress will. ...Read more

Can the doctor or radiolegist find CAD during cardiac CT scan test?

Can the doctor or radiolegist find CAD during cardiac CT scan test?

See answer: 2 two types of “cardiac ct exams”. The coronary calcium score is done without iodine contrast and identifies coronary vascular calcifications – which correlate with coronary atherosclerotic disease. The cardiac cta is done with iodine contrast and identifies the coronary vessel lumen allowing more accurate vascular delineation. Your dr. Can advise which is most appropriate for you. ...Read more

Dear wants to check for plaque in heart. He's doing a cardiac ct scan with contrast. Is this a good test for this?

Dear wants to check for plaque in heart. He's doing a cardiac ct scan with contrast. Is this a good test for this?

Yes: The cardiac CT is a very accurate test for seeing any plaque (cholesterol buildup) in the heart. It is more sensitive than an angiogram at seeing early blockages. It is more sensitive than a nuclear stress test, stress echo, or treadmill stress test. Check out my website CardioGauge. Com for heart health education. Best wishes! ...Read more

What gives better heart info, an ekg, angiogram or a cardiac CT scan?

All important: All are important -- ekg provides electrical and rhythm information. Much can be learned from an ekg. Angiogram/cardiac ct provides anatomic information about coronary arteries and myocardium (muscle of the heart). ...Read more

I have to have a cardiac ct scan. The dr said I will get BB to slow heart rate? Will it be in a pill?

For short term: It is probably intravenous. CT of heart can be overstated on the importance of the results. About 90 % of middle aged people have some hardening of the arteries. This is not very predictive of heart attack nor a reason for stents/bipass. ...Read more

I want a cardiac CT scan but am scared of allergic reaction to the dye, I have mild asthma. Can I request Benadryl (diphenhydramine) or how can I get round this?

I want a cardiac CT scan but am scared of allergic reaction to the dye, I have mild asthma. Can I request Benadryl (diphenhydramine) or how can I get round this?

See answer: Talk to your dr. / radiologist about the appropriate pre- procedure allergic preparation. It usually involves pre-procedure oral steroids (if you are an asthmatic already on steroids this may be modified), possibly an oral antihistamine, and may be performed in a hospital center depending on the severity of your prior iodine sensitivity. ...Read more

Can dexilant cause chest pain? Had cardiac ct scan, wore a monitor, blood work, chest X-ray, abdominal MRI, and Hida scan. All good. No stress test.

Can dexilant cause chest pain? Had cardiac ct scan, wore a monitor, blood work, chest X-ray, abdominal MRI, and Hida scan. All good. No stress test.

Not usually, as....: Dexilant is usually Rx'd for Acid indigestion/GERD and can be used to Treat "heart burn" that may be caused by increased acid secretion conditions. That being said, it is important to continue to have Cardiac reasons ruled out for your chest pain and follow-up with the Dr. As if the Dexilant is not helping, it may be another reason for your chest issues, best wishes. ...Read more

Is it always a problem for an asthmatic to have beta blockers before a CT cardiac scan to slow heart rate? Thank you

Is it always a problem for an asthmatic to have beta blockers before a CT cardiac scan to slow heart rate? Thank you

Not always: It depends on how reactive or brochospastic your airways are. This is highly variable. Some people tolerate beta blockers well, especially the selective (beta 1) blockers. Other people are exquisitely sensitive. Also it depends on how long it's been since you've had an asthma attack. If you had one yesterday, even if you feel well now, you're not back to nl yet. If you've been well, you're prob ok. ...Read more

Is CT cardiac calcium scan accurate in diagnosing mild ectatic ascending aorta? Have fam. History of heart disease (father died at 46 with chf) and slight heart murmur. Should I have other tests done

Is CT cardiac calcium scan accurate in diagnosing mild ectatic ascending aorta? Have fam. History of heart disease (father died at 46 with chf) and slight heart murmur. Should I have other tests done

No: You need an aortic ultrasound to determine if it is too large. A calcium score of the abdominal aorta is useless. A vest x-ray with abdominal view can tell you if you have a mildly ecstatic aorta or not but that is not harmful. If your doc is concerned the best test would be a stress test of your heart. Talk to your doc. ...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

Ct Scan (Definition)

Ct scan uses data from a beam of xrays and reconstructs a cross sectional image of your body. It is a high dose of xrays and used only when the benefits outweigh the risk. Cancer risk is 1 in 500 in children. Also using iodinated contrast might cause transient renal failure in about 5% of patients. (contrast induced nepropathy) most do not explain this to the patient as ...Read more
