What will a CT scan of chest show vs a chest x-ray?

CT is more sensitive. Regarding the lungs, ct is more sensitive in detection of pulmonary nodules and masses. If done with contrast, ct can also detect vascular issues like aortic dissection and aneurysm . Enlarged lymph nodes are also easier to detect on ct. In general, somethings that are easily seen on ct are difficult or impossible to see on chest x-ray.
Ct. Detects lessions, lymph nodes not seen on cxr , better detail of lung tissue, better resolution. Cxr have a big role , ct is not appropriate for everything, and you get more radiation with ct.

Would a CT scan of the chest, chest X-ray or an echo show any signs of aneurysm?

Usuallly. A ct of the chest is a really accurate way to see an aneurysm. Not always 100% accurate but pretty good. I have always been a sceptic of the belief that if you can't see it on the film, it isn't there. Books don't bleed, patients do. Read more...
CAT Scan. A cat scan chest will show an aneurysm in the thoracic aorta. To identify an aneurysm in the thoracoabdominal and abdominal aorta as well as in the visceral arteries, continuation of the cat scan to the abdomen and pelvis is advised. Read more...
YES. Assuming we're talking about an aortic aneurysm, all three can be useful in the detection of aortic aneurysm. Ct and echo would be the most sensitive. Read more...

Would a double contrast chest CT scan and a chest X-ray rule out fibrosis?

Not the best test. A high resolution CT chest would be the best study to evaluate fibrotic lung disease. Read more...

My mom was diagnosed with bilateral nodules in the lungs by a chest X-ray and CT scan. The doctor told her that her system is good and there is no sign or symptom of any disease. But I'm worried. What should I do?

Soooo... Nodule is not a diagnosis. It is a description of a finding on a study. Really need to know what kind of nodule. There are several types of nodules that are completely benign. He would not have told you all was well unless i really was. Doctors are generally very conservative. If her doc said not to worry why do you continue to worry? Maybe you should talk to them again.

Talk to the Dr. May be you can let the doctor know of your concerns. Lung nodules are nonspecific, particularly if they are small. There can be certain characteristics on ct that may indicate that the nodules are benign, eg, from old infections. Read more...
CT is better. If the ct either found nothing in the lungs (meaning the chest xray findings were overlapping structures or outside the lungs) or what was found was clearly benign on the ct scan, then there is nothing to worry about. This assumes a high quality ct scan read by a competent radiologist. Read more...

Had an adnominal/pelvis ct scan, a chest X-ray, and a lumbar spine X-ray all within a year. Does this significantly increase my cancer risk??

No. The radiation exposure form these studies is not likely to measurably increase your risk of cancer. For good health - Have a diet rich in fresh vegetables, fruits, whole grains, milk and milk products, nuts, beans, legumes, lentils and small amounts of lean meats. Avoid saturated fats. Exercise at least 150 minutes/week and increase the intensity of exercise gradually. Do not use tobacco, alcohol, weed or street drugs in any form. Practice safe sex. Read more...

I have some right superior mediastrinal widening in chest x ray. Dr asking for CT san. I m worried about radiation from ct. Should I get CT scan?

Yes. You need to know what the widening is. Most time it is a vessel . Sometimes lymph nodes. The amount of radiation from one ct is minimal as long as the number of these studies is kept to a minimal amount. Of course that would depend on what they find. Read more...

What is better CT scan or mir to further diagnose right superior mediastinum widening in the chest x ray?

CT scan. Mediastinum is best seen with a contrast enhanced ct scan. Mri is improving and could be used instead but i prefer ct scan. Right mediastinal widening could be due to a congenital anomaly such as right sided aortic arch. Have you reviewed this finding with your doctor? Read more...
