Will CT scan shows thickening in kidney?

Will CT scan shows thickening in kidney?

Ct is also good at showing the site of blockage of urine flow, when present. ...Read more

Would MRI scan show 
kidney disease?

"Disease": "Disease, " yes; but not necessarily what type of disease. "Dense"/scarred parenchyma may still need to be biopsied to determine the actual tissue disease. On the other hand, an MRI may be a better test to assess rensl masses (eg renal cell carcinoma vs benign neoplasms). ...Read more

Is orbital CT scan and CT scan sinus the same?

Is orbital CT scan and CT scan sinus the same?

Not quite: The CT of the sinuses focuses in on the sinuses (though the radiation goes through the entire skull) and generally covers the entire set of sinuses (sphenoid, maxillary, frontal, ethmoid). The orbital CT will cover the eye sockets (and those pictures are zoomed in). While the sinuses lies behind the eyes (& so they overlap), the focus & coverage of these scans are slightly different. ...Read more

Lung tumor CT scan with or without contrast?

Lung tumor CT scan with or without contrast?

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
