?

Parenchymal density: is a very nonspecific term, unfortunately. It could mean anything from scar to mass to pneumonia to collapse of a small lung segment. Without the images to review, it is difficult to determine. Likewise, there are both acute and chronic causes of cystic changes. The nonspecific report verbiage needs to be interpreted in conjunction with the images themselves and your clinical picture. ...Read more

Computed Tomography (Definition)

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

Had pneumonia three times in 10 months. Had recent CT scan which showed density on LLL of lung. What could be the cause of the repetitious pneumonia?

Had pneumonia three times in 10 months. Had recent CT scan which showed density on LLL of lung.  What could be the cause of the repetitious pneumonia?

Airway blockage: Seems likely that you have some structural issue of the airway that is preventing clearing of secretions and causing recurrent pneumonia. Could be something you aspirated, something causing compression like a lymph node, or some other type of abnormality. See a pulmonologist and or thoracic surgeon because three pneumonia a in 10 months is abnormal and worrisome. ...Read more

CT findings: None of these findings are specific. There may be more description provided by the ct that was not included in your post which may be further explaining the findings. It may be helpful to discuss these findings with the physician who ordered the ct or with the radiologist who read it. ...Read more

I have trouble swallowing but not all the time. Sometimes I really have a hard time swallowling and other x no problem. I had CT scan show small calcific densities in right lobe of thyroid gland. Could this be the cause even though I don't kno what the ct

Need evaluation: There are many possible causes for your current symptoms. Although the ct showed "small calcified densities in the thyroid", it still might not be the cause for your difficulty swallowing. The next step would be a thyroid u/s to see if these "densities" are in a nodule and to see how many nodules & how big they are. Get the ct result, sit down with your doc and discuss the next step of evaluation. ...Read more

Is it normal to have CT scan say stable increased lobulated density in anterior superior mediastinum may represent residual disease vs thymic tissue?

Is it normal to have CT scan say stable increased lobulated density in anterior superior mediastinum may represent residual disease vs thymic tissue?

Mediastinum: Of course it depends on many factors. It's normal to see thymic tissue until early 20s is seen in fewer than 50% of people over 40. This density can be possibly be anything including normal, reaction to infection, thymic cysts, or hyperplasia from systemic disease. Fortunately it is stable, but a conversation with your doc and radiologist would be the best thing moving forward. ...Read more

Ct Scan (Definition)

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
