Fasting For Lung Ct Scan
Follow established : Depends on smoking, infection, enviornment history & size of nodule. At ~1.2 cm, ct or pet-ct may be indicated in 3 mos. With hi suspicion and no prior nodule, could biopsy now. Else consider that if repeat scans in 9-12 then 24 mos are all stable, then could stop scans. ...Read more
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
More info: If the ct appearance is non diagnostic, and there are no old studies for comparison, further evaluation may depend on location and size. If the module is bigger than approximately 1 cm, pet/ ct may be helpful in further characterization. Some nodules are amenable to end a bronchial ultrasound guided evaluation. Biopsy may be needed to obtain an exact diagnosis. ...Read moreSee 1 more doctor answer

Many things: The general categories are Infection, Cancer, Non-cancer tumors, collapsed lung, blood, fluid, and more. The radiologist should be able to narrow down the potential causes from the appearance. Ask for a detailed radiology report. If this doesn't satisfy you, speak with your primary care doctor. ...Read more
Infection, Cancer, +: Infection, hemorrhage, tumors (benign and malignant (cancerous)) fluid and even fibrosis can have a similar appearance. If it is mostly calcified, it is likely benign, old infection called a granuloma. Comparison to older scans can help determine if it has grown. The concern is whether or not it is cancer. Recommend seeing a primary care provider, perhaps a pulmonologist consult and pet/ct. ...Read more
Need to know more: About the findings on a ct. I am not familiar with the term "lung polyps". Pulmonary nodules are quite common, and depending on appearance, density and stability (if an older scan is available), can be accurately classified as benign. Unfortunately, although most are benign, for many patients, we cannot tell for sure on 1 scan, so further workup is necessary. Please discuss this with your doc. ...Read more
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 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
