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?!

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?

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.

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?

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.

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

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

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.

Ct scan with contrast found a 3mm nodule in my left lung, minimal dependent atelectasis, & an exaggerated cardiac silhouette. What does this mean?

Pulmonary nodule: Any nodule in the lung, no matter what size, needs to be investigated thoroughly. Comparison with previous chest xrays and CT scans would be the priority. If you smoked tobacco, then further tests such as a PET scan and a biopsy and bronchoscopy are indicated. Please see a pulmonologist soon. Best wishes. ...Read more

Is it likely to have a heart attack with NORMAL chest CT scan, chest ultrasound, numerous EKGs, and cardiac enzymes in the last year. 32/F/NS/ N Hist.

Modify risk factors: Normal ekg, echo, cardiac ct cardiac enzymes can be useful to rule out a heart attack. At age 32 however we are still capable of building plaque in our arteries. Plaque does not suddenly appear. It starts in young adolescent age. Modifying risk factors includes healthy diet full of lots of plant food. Small amts healthy fats, minimal animal foods, no processed foods and daily exercise&no smoking ...Read more

Not high: Even if you were 20 years older, the findings are not supportive of a cardiac issue. Need to know whether the pain is worsened by exercise, certain activities such as eating. Other than a chest cage issue (costochrondritis) one needs to consider a problem with the esophagus as well. ...Read more

What is coronary calcium score? I had a CT scan and my total coronary calcium score is 102. What does this figure mean, bad, good or otherwise.

CAD & CALCIUM: The presence of calcium means hardening (atherosclerosis) of heart artery. Inside the artery wall the fat, inflammation and calcium form plaque. The larger the score, greater the plaque burden and high risk of heart attack. 0-10 no plaque. 11-100 mild. 101-400 moderate and >400 severe plaque. 102 is mild- moderate. Lipitor (atorvastatin) & Plavix good. Sometimes higher number but no obstruction on angiogram. ...Read more

Is a coronary calcium ct scan a good test to see of there is plaque in the heart arteries? How accurate is it? My cta was inconclusive. Heart rate fas

Coronary Calcium: Coronary Calcium analysis is a method to detect calcified cholesterol in the coronary arteries. A score of zero is quite helpful and predictive in the correct age group. The difficulty is that in younger people, there may be noncalcified cholesterol plaques in the arteries which would not be detected on a coronary calcium screening test, so cardiac CTA or invasive angiography would be considered. ...Read more

Ct scan of coronary arteries done in ER says 70% block or artifact. Follow up nuclear stress test 100% normal cardiologists says. What to think now?

Heart...: Cardiac ct is anatomic imaging. Nuclear stress is more functional imaging. Without seeing your ct it is hard to say but if there was a calcified plaque in the coronary, a blooming artifact is possible. If nuclear stress was normal, that's great. You may still have coronary disease which is not hemodynamically significant. You are young for significant heart disease. Discuss with your doctor. ...Read more
