Lung Scarring Ct Scan
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
Either: I usually do them without so I don't expose the patient to the contrast, which can injure kidneys. However, if the tumor is close to the mediastinum, I usually do order it with contrast because it's often difficult to tell the various structures apart without it. It also helps to identify lymph nodes. ...Read more
Not likely: The natural exposure one might get just from where you live may exceed 3msv per year. Living in denver, you might be exposed to 6msv per year. Risk of developing cancer from a properly conducted ct scan is low. I believe the estimated average radiation exposure for a single chest ct is about 5-7msv. A low dose chest ct is about 2msv. ...Read more
Not sure: Ct with and without xray dye is a good test for some kidney problems. Not sure what you mean by thickening. Ct shows kidney stones, masses, kidney size/location ; can give a good idea of whether the kidneys are working well. Ct is also good at showing the site of blockage of urine flow, when present. ...Read more
What's difference between High HD Contrast CT scan vs Normal Chest CT with contrast evaluating interstitial lung markings?
Different chest CTs: High resolution chest CT usually with out intravenous contrast is used to define interstitial lung disease pattern, whether diffuse or localized process. CT of chest examination with contrast intravenously usually looking for tumors or metastases and acute infection in the lungs. ...Read more
Had a CT abdominal & pelvic scan found a 7 mm lung spot on the lower left lung. Radiologist wants a CT lung scan done ?
Dx of lung nodules. Ct scans of chest two years. Had chestxr CT scan of chest 2012 2013 CT scan of chest pulm wants another im afraid it causes cancer?
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 moreSee 1 more doctor answer
Had a CT abdominal & pelvic scan found a 7 mm lung spot on the lower left lung. Radiologist wants a CT lung scan done. Thoughts?
Get it done: The ct will show if you have other nodules or evidence of previous infection, such as histoplasmosis, that commonly cause nodules. After that your doctor can know if you need any further procedure or followup. Don't worry too much, these nodules are common and mostly benign. ...Read moreSee 2 more doctor answers

Mgt: There may be several possible conditions associated with these findings. Infections may cause cysts. I would suggest a TB test and uploading the scan to your virtual EMR. ...Read more
Sort of...: The pet scan non-specifically show very metabolically active (consuming lots of energy), and lung cancer and its metastasis fit that category. It is not specific. Benign conditions like sarcoid can also make pet studies glow very brightly as well. Slow growing lung cancer, broncheoalveolar may not be pt avid. ...Read moreSee 2 more doctor answers
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
