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

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

Feel sitting on my croccyx since 14days, from cat scan &xray its fractured.when could I normally sit, drive & normally bent my back plz?

Tincture of time: Fractures in any part of the body take time to heal up. The same could be expected from a coccyx fracture. My best advice would be to get a donut cushion, and lumbar support which should definitely help with your symptoms. We are talking about at least 3-4 month before fx heals up completely. Consider tylenol (acetaminophen) for pain. Also, if post menopausal consider bone density scan to r/o osteoporosis. ...Read more

In december he had a chest xray for at that time, a single nodule observed. Cat scan now shows 2 benign nodules w/ 1 inflamed. What next?

Discuss with doctor: Discuss the situation with your doctor. What to do next depends on the actual images on the ct and the opinion of the radiologist (a doctor specializing in image interpretation). Your doctor may need to talk to the rad. Sometimes the ct can clearly determine if the nodule is benign, but sometimes followup ct's are required. If there is an old ct to compare with, that would be extremely helpful. ...Read more

I was having cough for three weeks so advised chest X-ray , which showed cyst in diaphragm. Further i got cat scan but it was clean. What should I do.

I was having cough for three weeks so advised chest X-ray , which showed cyst in diaphragm. Further i got cat scan but it was clean. What should I do.

What does Doc say?: Please discuss this with your physician. There may have been a lucent area near your diaphragm, sometimes called a lung cyst, bleb or bulla. Without the x-ray it is hard to know. If definitely benign or stable when compared to an old x-ray, further workup may not be necessary. However, if there are any symptoms or concerns, chest ct is more sensitive, specific and accurate than chest x-ray. ...Read more
