What Is Lung Parenchyma
Would calcium coronary scoring results be affected by having multiple tiny nodular densities within lung parenchyma or scarring .How reliable the test?
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 chest w/contrast found multiple tiny nodular densities within lung parenchyma. How serious is it. I get sob when i bend over or do yoga exercise. ?
Possibly: These are unlikely to cause shortness of breath. Most commonly these nodules are evidence of a prior infection such as histoplasmosis, especially if you have resided in the ohio river valley, or less likely tuberculosis. These are known as granulomas. However, other causes are also possible. Your doctor that referred you for the scan should be able to determine if you need more tests. ...Read more
Took brain mri.multiple t2hypointense lesion in cerebral parenchyma.possibilty of granuloma or brain secondries..my mom hv lung cancer.is it secondary?
Probably neither: Difficult to know without seeing all the MRI sequences. It would be helpful to know if the lesions enhance after Gadolinium contrast and if they "bloom" on susceptibility weighted sequences and if they are calcified or invisible on CT scan. Metastatic disease would be very unlikely in a 30 year old without a known primary cancer. My best guess would be multiple cavernous malformations. ...Read more
Vitamin A: Take vitamin a to keep your lungs healthy. Two studies involving mice, "vitamin a deficiency injures lung and liver parenchyma and impairs function of rat type ii pneumocytes" and "retinoids have differing efficacies on alveolar regeneration in a dexamethasone-treated mouse, " show that cigarette smoke depleted the lungs of vitamin a and that the lungs' air sacks healed once given vitamin a. ...Read more
What does this mean(x-ray reading):slightly limited inspiration on lateral view compressing the basilar parenchyma ?
Incomplete breath: It means that the radiologist felt that you did not take a complete breath in (or the pictures were taken after you started exhaling) during the process of getting the X-ray. As a result, the part of the lungs near the bases (bottom) seem to show up more dense than the rest of the lung. Again, radiologist felt that this is due to incomplete breath during the X-ray procedure. ...Read moreSee 1 more doctor answer
Extranodal lymphoma: Lymphoma in the lungs may be in the lymph nodes (nodal) or in the lung parenchyma (lung tissue itself = extranodal = outside of lymph nodes). While theoretically any lymphoma may involve the lungs some more common ones might include - marginal zone lymphoma, primary mediastinal, effusion lymphoma, dlbcl... ...Read moreSee 1 more doctor answer
COPD: These are diseases of respiratory system in which air is trapped in the lungs. In majority if not all of them airways are involved. Asthma, COPD and emphysema are part of it. In emphysema lung parenchyma is also affected by loosing elasticity. Cause is usually unknown, could be smoke related, genetic or as part of other disease such as rheumatoid arthritis, or auto immune disease. Shahzeidi, md. ...Read more
An array: The lung can be a site of metastatic cells shed from their primary and contaii a surface glycoprotein allowing implantation in lung parenchyma. The primary lesions that arise in the tracheobronchial tree are squamous and associated with smoking. The adenocarcinomas which are now most frequent are possibly viral in origin and the small cell neuroendocrines are similar to carcinoid of bowel. ...Read more
Bad: Pneumothorax, hemothorax, chylothorax, hydropneumothorax and atelectasis all emcompass conditions where a lung is "collapsed." in atelectasis, the lung is not aerated because alveoli are not expanded. This is usually an issue internal to the airways. The rmainder are due to something outside the actual lung parenchyma - compressing the lung. All are bad, so talk to your doc. ...Read moreSee 1 more doctor answer
Depends on severity: Autopsy specimen of patients with advanced emphysema shows blackened lungs with punch out holes, like swiss cheese because of destruction of lung parenchyma and large holes formation because of collapse of lung alveoli and formation of blebs and bullous cavity. However, this is the end stage disease. ...Read moreSee 1 more doctor answer
