Lung (Definition)

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

Radiation from CT: This issue should be discussed with your pulmonary doctor and radiologist. There is some risk associated with the radiation from multiple ct scans. However, that risk is likely small compared to the risk of a nodule identified in the lung, and may not outway the risks of ct, in the long run. There should be a plan with a reasoned approach that minimizes the risk of ct that you can agree with. ...Read more

My two year monitor for lung nodule be over in fall 2014. Will i need monitor after that with CT scan of chest. I am concerned about the radiation.

My two year monitor for lung nodule be over in fall 2014. Will i need monitor after that with CT scan of chest. I am concerned about the radiation.

Many factors...: Need to be looked at. Age, smoking, family and previous cancer history. Also characteristics of the mass. Radiation does have a risk. If your doctor agrees and you are low risk, then perhaps plain cxr is adequate yearly if there is no change and features are low risk. Discuss it in detail with your doctor, but don't ignore it. Stable nodules can and do change. ...Read more

Had CT scan 6 years ago. 2 mm and 2.5 mm nodules found. Recently found 11 mm nodule in lung. Could one of these have grown in the past 6 years?

Maybe so: It is possible that this is one of the nodules that were previously present however it is not certain given that time interval. Talk to your doctor and follow up as directed. As always, if you feel like you need a second opinion, you should get one! ...Read more

Had a full body CT scan. Doctor found a 5mm nodule 3 mm nodule and 2 mm nodule on my lungs. I'm 25 don't smoke. Colonoscopyendoscopy normal. What now?

Had a full body CT scan. Doctor found a 5mm nodule 3 mm nodule and 2 mm nodule on my lungs. I'm 25 don't smoke. Colonoscopyendoscopy normal. What now?

Nothing: Full body ct scanning as a screening test is not recommended for just these reasons. Three tiny nodules in the lungs were found and now there ensues a workup for them. Colonoscopy and endoscopy to look for a cause for the nodules? If so that is an over-reaction. Chances that the tiny nodules are cancer in a 25 year old nonsmoker are very low. At that size they can be observed with follow up scan. ...Read more

Saw a 3 mm nodule during a CT scan at the base of my left lung. What could it be?

From nothing: To an early something. The anxiety you are experiencing is given as a main reason to not do screening ct's in smokers. 3 mm is too small to worry about. If it were me, i'd re-ct in 6 months to a year to check change in size. You can google the nlst - national lung screening trial. Do you smoke? Time to stop if yes. Good luck. ...Read more

I had a CT scan and it showed a nodule on upper right lung that is 9 mm. Is that big as I am now scared?

I had a CT scan and it showed a nodule on upper right lung that is 9 mm. Is that big as I am now scared?

See a lung doctor: any lump or mass need to be checked regardless of the size 9 mm is not a large mass but it still need to be checked and biopsy if possible if you are a smoker i will take it more seriously you still have a lot of reason for the lump to be benign but still need to be checked good luck ...Read more

I had a CT scan which showed a 3-4 mm nodule in the lower left lung. I was a smoker for 40 years. Does that have anything to do with it?

I had a CT scan which showed a 3-4 mm nodule in the lower left lung. I was a smoker for 40 years. Does that have anything to do with it?

Can't Tell Yet: Is the nodule uncalcified? Is this the first time it has been identified? Any prior ct scans? If this is a new finding with no prior scans there will probably be a suggestion to rescan you in 6 months to check for growth. If no change then another scan 12 months after the repeat. Most such nodules are incidental and are sequelae of prior infections. Important to followup though. ...Read more

What's a difference between lung nodule and intrapulmonary nodule? What's smallest size in mm that can be detected on CT scan?

What's a difference between lung nodule and intrapulmonary nodule? What's smallest size in mm that can be detected on CT scan?

No difference: They are two terms for the same thing. The smallest size detectable depends on the type of CT scanner and the technical parameters of the scan. A high resolution, thin section scan could potentially detect lesions 1mm or so in size. ...Read more

Will i need a new CT scan to check cause & to treat a 2mm granuloma and 8 mm slightly lobulated well defined nodule? It was seen in lung CT 4 months

Lung nodule: New lung masses found on imaging should be followed or biopsied. Many small lesions less than 1 cm in size are observed. If it is enlarging or is associated with symptoms such as cough, or coughing blood would be worrisome. Prior ct scans that show the mass previously would be reassuring. Risk factors for lung cancer such as smoking would raise suspicions. Speak with your md, yes to repeat ct. ...Read more

In oct i had a CT scan of my stomach and they seen several nodules that were 5 mm my ins co denied the CT referal on my lungs I have shortness?

Ask your doc: The doctor who referred you for the original ct scan should be able to communicate with the insurance company to follow up on the "nodules." if you did not have a referral originally, ask your doctor about the findings and they should assist you anyway. ...Read more

Ct scan from 1 month ago showed my lung nodule grew 1 mm. Will a pet w/ CT tell me if its cancer?

PET scan: Tumors generally have a higher metabolic rate and a pet ct make use of this. Tumor usually lights up on a pet scan. If the tumor nodule is very small it will likely be missed on a pet scan. ...Read more

My husband had a CT scan of his chest 3 times, all the times it showed something but this time it showed an existing nodule in the right lung and a new nodule measuring 4 mm in the right upper lobe. The left lower has hazy markings. My husband is a former

Need evaluation: He would need further evaluation. The fact that he is a former smoker, still gives him significant risk for lung cancer. I dont know the size of the 1st nodule- if possible, a core biopsy should be done to rule out malignancy. A pet scan also needs to be done if not been done in the past- although however, negative finding on the 2nd nodule will not rule out cancer completely due to its size. ...Read more

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 more

2 nodules found in my lungs. 7 and 8mm. smoker for 35 years. Why wait 3 months to see if they grow for 2nd CT scan as opposed to doing biopsy now?

Risk: Inserting a needle or going through your airway to get these small spots can cause more harm including death. This protocol of rescanning can decide if it is indeed cancer. Small growths like these could be noncancerous. Good luck ...Read more

Computed Tomography (Definition)

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

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
