Pleural Effusion And Ct Scan Lung Cancer
Cancer is a group of diseases that is characterized by uncontrolled cell growth leading to invasion of surrounding tissues that spread to other parts of the body. Cancer can begin anywhere in the body and is usually related to one or more genetic mutations that allow normal cells to become malignant by interfering with internal cellular control mechanisms, such as programmed cell death or by preventing ...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
See details: Please ask this question to the doctor who ordered the tests. That doctor is the only one who can put this result in context for you. The reading, unfortunately, suggests the underlying cause is a malignancy. However, there are other possible causes. That is why your own doctor will be the best one to provide an answer. ...Read moreSee 2 more doctor answers
What does "nodularity of visceral pleura" mean on CT scan? Was diagnosis with pleurisy and pleural effusion with atelectasis.
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
Ct angiogram shows non calcified opacity on middle lobe 4mm. Appearance of benign intrapulmonary lymph node on lung with no pleural abnormalites.
Opacity: The question to your doctor should be - is this an incidental pulmonary nodule or something more concerning. If the ct angio was done for something completely unrelated, and it was a true incidental finding, some guidelines say that under a certain size (4mm) for low risk patients (no smoking, etc), then no follow up is needed. Otherwise a biopsy or interval imaging followup is appropriate. ...Read more
Xray results showed perihilarbronchial wall thickening w/ perihliar densities w/out evidence of pleural effusion, focal consolidation or pneumothorax?
Ct chest adrenal nodule 1.9 CM right. Lungs demonstrate babisalar dependent atelectasis small subpleural bullae noted right up lobe trace pericardial?
Adrenal eval: Hi. The adrenal nodule needs to be evaluated. What were the Hounsfield units on the non-contrast scan of the nodule? Your endocrinologist will determine: 1) if it's producing any hormones, and 2) if it's growing. If high Hounsfield units, it needs sooner evaluation. Any hirsutism, amenorrhea, diabetes, serious high blood pressure, sweating, headache, palpitations, etc? Good luck! ...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
Is it possible that CT scan shows no pleural masses while I have lung cancer and massive effusion?
Unusual but yes.: CT scans have limited resolution. They do NOT see everything. Usually large pleural effusions come from significant disease, but not always cancer. The only way to tell is to have the pleural effusion drained & sent for cytology & other testing (culture). The lab techs can spin down the fluid, isolate cells or bacteria that may be causing it. Talk to a pulmonologist or your primary doc. Good luck! ...Read moreSee 1 more doctor answer
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
Not necessary: Are you referring as small lymph nodes or small nodules on the lung? There are other conditions beside cancer that can be presented with small nodes - including infections, inflammation, autoimmune process, etc. So, a good history, examination, blood work and serial imaging would be necessary to be done. Discuss with your md in detail. ...Read moreSee 2 more doctor answers
Would lung cancer cause enlarged hilar and mediasternal nodes, GGO on Chest CT and impaired gas exchange. Other lung function tests are normal?
Possibly: There are many different forms of lung cancer however the most common types usually appear as a solitary nodule or mass on CT. GGO can be seen with lymphatic involvement as is suggested by the enlarged lymph nodes described. This can be from infection, cancer or autoimmune diseases such as sarcoidosis and even heart failure. A biopsy of an enlarged lymph node may be required. ...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 more
Hist chest pain and hemopsys. normal CXR CT shows calcified hilar node. Ca of 10.8 now 9.7 Dr Doesnt think Squamus lung cancer no smoker Bronchoscopy?
See below: Is this your PCP or pulmonologist saying this? There are many causes of enlarged hilar lymph nodes. Also, if it is calcified, that is usually just a sign of old granulomatous disease, like histoplasmosis. And at 31, that would be unusual to have lung cancer - not unheard of - but unusual. ...Read moreSee 1 more doctor answer
Several posibilities: Often this may be due to infections like histoplasmosis (which is quite frequent in the mid-west), but the best thing to do is to have this thoroughly evaluated by a pulmonary (lung) expert. It may require bronchoscopy after appropriate imaging studies, and possibly other procedures, but the importance of establishing a firm diagnosis cannot be over-estimated. Good luck. ...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
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
