Is it possible for a CT angiogram to cause a stroke?

No. No. Ct angiograms do not cause strokes. Ct angiograms of the head are used to diagnose stokes and ct angiograms of the head/neck and chest can help diagnose the cause of strokes. There is risk of radiation exposure and contrast toxicity (can impair kidney function).

I'm 21 with tachycardia issue, had an echo, ekgs, cardiac CT angiogram, bloods, chest ct, 24hr holter. Keep getting sweaty and tight in the chest and sometimes skipped beats eating dinner. Causes?

Brain ≈ Heart Rate. Without brain input, heart rate ~110 bpm. Heart, (like rest of our body) & heart rate constantly split second controlled from brain. Vagal acetylcholine release slows rate, sympathetic adrenaline/noradrenaline release increases rate. Fear/anger/stress (subconscious), high thyroid hormone, low heart output (for whatever reasons) & re-entry circuits are common reasons for rapid heart rate. Read more...

Can you explain how a CT angiogram differs from a regular ct?

Contrast & Thickness. Ct angiograms are ct scans with IV contrast. The most unique difference is the thickness of the "cuts". Ct angiogram cuts are typically 2.5mm or thinner. With this resolution 3d reconstructions can be created of the arteries. Read more...
Timing. Cta performed with thinner cuts and timing to catch the contrast in the arteries. Otherwise they are the same. The data is processed by a computer afterward to highlight the vessels with cta. Read more...

I was wondering is a CT angiogram of the chest the same as CT chest with contrast?

CT techniques. They are similar in many ways. However, the timing of the contrast for CT angiogram is different to allow for better visualization of the blood vessels in the chest. Read more...

I had a CT angiogram of chest with contrast and now my dr wants me to have one without contrast. I thought with contrast was always better?

Not necessarily. Ct angiogram is a study which uses contrast to enhance blood vessels and so the timing of imaging relative to imaging will vary depending on intended vascular structure. Non-contrast ct, especially high resolution would be used to evaluate the lungs. Repeat ct without contrast may be used as a follow up study as well, to avoid repeated use of contrast. Read more...
With and without. Calcium looks just like contrast on a ct scan. Doing a study with and without will let you see what was simply calcium and what could be blood flow ( contrast is in the blood stream so represents blood flow ). It can be very important to differentiate between the two. Read more...

36 year old f: ef was measured at 65% with a 2d-echo. 6 weeks later it was measured at 55% during a CT angiogram. Should this be reevaluated? Thank!

EF. No. They are both within normal limits. With different tests and interpretations there can be variablity. Read more...
EF. Techniques for measurement of ejection fraction often yield different values. Ef by echo is a calculation with geometric assumptions as is the ef from cta, both values you got are normal, you don't need more testing especially if you are doing well. Why did you have a cta at 36y/o? Read more...
