Chest X Ray Pneumonia Vs Lung Cancer
Yes: Chest xray looks at the lung tissue superimposed on a the chest wall tissue including the ribs and all the muscles and thus can miss subtle findings. In addition, lung infection can be subtle, with presentation as a small focus of infection or a rather very faint infection area that can be very difficult to detect with xray alone. A ct study may be useful if necessary. ...Read moreSee 1 more doctor answer
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
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
Chest X-ray Hyperinflamed lung and perihilar bronchitis changes are seen.No acute pulmonary or pleural disease.25 year,non smoker,Please explain findi?
Might be normal: I obviously have to make some assumptions without seeing the films myself. First, I believe that "hyperinflated" was meant instead of hyperinflamed, as it is a more common term. It is used often when lungs appear over expanded.Although it sometimes suggests air trapping seen in asthma, or copd... It tends to be overused...and is often seen in normal people who are able to take a very Deep breath ...Read more
Sometimes: Sometimes 8-10 mm lung lesions can be detected. Detection depends on location of lesion whether it is central or peripheral. Central lesions near mediastinum are many times difficult to recognize on plain radiograph. Cross sectional imaging such as CT is much more sensitive for small hidden lesions than radiograph. ...Read moreSee 1 more doctor answer
Not easily: Cxr has been compared head to head with chest ct scan for screening in high risk patients for lung cancer. That study, national lung screening trial, found that in high risk patients, screening chest ct scan was more effective, and was found to save lives. Larger cancers might be seen on a cxr, but smaller cancers may be missed. ...Read moreSee 2 more doctor answers
Good but not perfect: A properly taken xray can reveal a great deal about many lung disorders, but not all. Present technology allows us to increase and decrease magnification, contrast and see more than we did years ago, but there are limits.Some disorders produce obvious changes on xray, while other do not. ...Read more
I have stage 2 emphysema and 4 lung nodules on a ct scan (3mm and smaller) shadow xray and CT scan. Shortness breath, chest pain, night sweats?
Mgt/workup: Your findings are of concern, and an exam documenting any lymphadenopathy is important. I would suggest seeing your PCP. Your symptoms may also be due to TB, cardiac disease, pulmonary embolism. A virtual online appt is available for follow up and to review your HRCT. healthtap.com/DosanjhMD Code: NCYHPZ ...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
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
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
31 m - Is a bronchoscopy / chest Ct scan with contrast and Vq scan good enough to rule out lung cancer or lung problems ?
Lung eval: That is a very through evaluation and should be sufficient . You could see masses, tumors, emphysema, frbrrosis, note if abnormal cells, tell if there are emboli. Adding pulmonary function testing (PFTs) would assess the function i.e. tell if you have asthma . f/u/ w/ doc ...Read moreSee 3 more doctor answers
It depends...: It depends on the area covered by the x-ray and on how enlarged the lymph nodes are. A chest x-ray would probably show significant lymph node enlargement that may be suspicious for lymphoma in the mediastinal area (inside the chest cavity) and possibly in the supraclavicular (above the collarbone), lower cervical (neck), and axillary (armpit) regions. Inguinal (groin) lymph nodes would not show. ...Read moreSee 2 more doctor answers
Can TB lympadentitis cause lung scarring without having pulmonary tb? Chest xray show only enlarged gland.
Highly unlikely: TB lymphadenopathy is initiated when macrophages carry the bacillus from a pulmonary alveolar focus to the lymph node which then enlarges, suppurates and ruptures into an adjacent blood vessel. So it is virtually impossible to have pulmonary nodes involved without having pulmonary infection first. ...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
A chest x-ray is the basic radiographic study for evaluation of the heart and lungs. It usually consists of 2 views: postero-anterior and lateral. The image is now usually acquired digitally with the sensor placed against the front of the chest for the pa view and on the left side of the chest for the lateral view. Pneumonia, heart enlargement, CHF and many other ...Read more
