Ct Lung Nodules Appearance Of Granulomas
On feb 2012 after CT lung scan a 2mm lung nodule was found. Do i need to retest? Can a 2mm lung nodule disappear and if yes how long does it takes?
Need a followup: 2mm is really below any diagnostic resolution of ct. In your age, it most likely represents a bening finding, rather than a lung cancer. You should have had a follow up scan 3-6 months to assure either resolution of the nodule or to determine if it got larger. These can easily disappear if inflammatory. ...Read moreSee 1 more doctor answer

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
Severe chest pain, calcium screening showed chronic pulmonary hypertension& lung nodules. Had CT of chest 3mm & 8mm noncalcified granulomas.helpplease?
Lung nodules: many causes of lung granulomas. Histoplasmosis a fungus in the dirt is probably most common cause. Being around construction sites or bird handling are frequent causes especially around Ohio river. Connective tissue causes like sarcoidosis and wegeners can also cause. Working in dusty areas or around talc is known cause. With pulmonary hypertension you need to see a pulmonologist for definitive dx ...Read moreSee 1 more doctor answer
Yes: There are differences in techniques between the ct scan with a pet scan and a general ct scan. Additionally, radiologists may measure a nodule slightly differently. Please look at a ruler and realize just how small 1 mm is. Radiologists routinely are measuring things less than 1 cm or about 3/8 of an inch. ...Read moreSee 2 more doctor answers

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
(36 and smoker)What could 3 noncalcified lung nodules sizes 6mm- 4mm left lower lobe be? Found on ct, what would be next step to identify cause?
Many possibilities.: Noncalcified lung nodules are worrisome, especially if you are a smoker (as you have), & more so if you are a "heavy" smoker (based on number of packs per day, & no of yrs that you've smoked). A nodule could be scar tissue, or the effects of an infection or radiation; however, most worrisome, of course, is lung cancer. To identify cause, next step is usually bronchoscopy (scope to look) & biopsy. ...Read more

2mm sublpureal lung nodule in periphery base.28/f 10yr smoker, quit 4 years ago. Found by accident on ct. Petrified its cancer. What are the chances?
Probably not cancer: Congratulations on stopping smoking! at your age, your risk of lung cancer will be low if you stay off cigarettes. A 2mm sub pleural nodule is likely benign. You should have another ct scan within 4 to 6 months to assure that it isn't growing. If it is not, you can safely put it out of your mind forever or just do one more ct scan one year later. If growing, have it removed to rule out cancer. ...Read moreSee 1 more doctor answer

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
