Which type of CT scan required for detecting metastatic clear cell renal cancer in chest/abdomen, is it plain or contrast ?

Which type of CT scan required for detecting metastatic clear cell renal cancer in chest/abdomen, is it plain or contrast ?

This sounds like: Radiology calling. It should be the radiologist deciding, but the contrast tends to identify vessels, and some tumors "flush" with contrast. The contrast is iodine based.

Inflammatory?: You need to know if is inflammatory and a sedimentary rate, RA factor, and nuclear scan can rule this out. If not inflammatory, the pain pattern suggests sacroiliac joint (sij) dysfunction, which cannot be seen on ct and MRI scans nor any other imaging study, as reported in the medical literature.

What types of brain tumors won't show up on a CT scan?

What types of brain tumors won't show up on a CT scan?

Small low grade mass: Some small low grade tumors that have not incited vasogenic edema could be missed on ct scanning. The addition of IV contrast would improve visualization of some tumors, but ct has limits in resolution when compared to mri. These are not the tumors that cause profound symptoms, frequently these small tumors are found incidentally when patients have scans for other reasons. ...Read more

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
