White Spots On Lungs Ct Scan Solitary Pulmonary Nodule
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
I have white spots on my lungs. My doctor does not know what they are. I went and had a ct-scan today. Hoping to know the results friday.?
Wait for CT.: Your doctor probably has a pretty good idea what they are and what they are not likely to be. Ct will be very informative and perhaps definitive. ...Read more
What bloodwork would be used in diagnosing pancoast tumor? I am waiting to have CT scan due to apex lung nodule.
Usually none: A pancoast tumor (name of radiologist who described it), is a tumor involving a specific site in the lung, but it does not give the specific type. Usually they are adenocarcinoma or squamous cell carcinoma, but you need a biopsy to prove this. Do you smoke? You are young for a lung cancer, even though you have thallasemia. Do not worry until a biopsy and ct have been performed. ...Read moreSee 1 more doctor answer
Had a CT scan it showed a 7cm lung nodule it may be benign I'm going to have another CT scan in 6 months to see if it has grown I'm a little concerned?
Lung Nodules: are very common and fortunately most of the time are benign. Many people actually have these and are unaware. There are certain characteristics of nodules such as size and appearance that may sometimes be more worrisome. Also, a history of cigarette smoking may be a cause for concern. 6 months is a standard screening period for lung nodules. ...Read more
My dad has a lung nodule that has been stable for 5 years. This year the CT scan showed it grew 1mm. Can CT measurements be wrong?
Yes, it is not exact: Growing lung nodules can be cancer. But the growth has to be real which means increase of more than 2-3 mm before we can get concerned. The cross sections on ct are rarely at the same level so there is one or 2 mm variation between serially done ct scans. ...Read moreSee 1 more doctor answer
Had ct scan 1.5yr ago found 5 mm lung nodule repeated ct year ago the radioligist stated no folow necessary, no changes smok free since still concrn?
Can a stable over 4 yrs lung nodule at 5mm grow to 1.6 mm in 12 months or be effected by a dental injected sedative the day before CT scan ?
Lung Nodule: An injected dental sedative has no effect on a lung tumor. A stable nodule may be a tumor, or it could be a scar from a previous localized infection. Most malignant tumors will grow considerably in 4 years; doubling in size in 12 months, however, raises the question that it is either a tumor in a growth phase or a granuloma or other form of chronic infectious process that should be followed up. ...Read moreSee 1 more doctor answer
Ct scan showed very small lung nodule. I've had 3 chest x-rays prior and nothing showed on them. What happens now? How to determine if it's cancer?
Depends: If the nodule is very small, it would not be seen in a plain x-ray so the fact you had 3 prior negative ones does not mean much. You may have had it undetected for years. Depending on how big it is and your clinical situation, your doc may opt to follow up with another ct scan in 6-12 months, do a pet scan, or proceed with a biopsy. Good luck and if you are a smoker, quit today. ...Read moreSee 2 more doctor answers
Deoxygenated blood enters the lungs from the right side of the heart and travels to the lungs. When you inspire, oxygen flows into the lungs, transverses the capilliares and attaches to hemoglobin down a gradient. At the same time, co2 diffuses into the capilaries and is expelled with exhalation. Oxygen rich blood then flows to the left side of the heart and into the ...Read more
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
