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
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 moreSee 1 more doctor answer

My CT scan report reveals polyp retention in left maxillary sinus and bilateral sphenoid sinuses,polyp measures 3*1.8 cm.Is surgery necessary?
Usually: Sometimes a spinal cord tumor, especially with extrinsic compression, can result in false localizing clinical signs, which could result in imaging at wrong level, but if precise, the MRI will show lesion. However, you say that you have B-12 issues, and this can cause spinal cord problems in posterior columns, which are also seen on MRI. Do you feel Concierge visit might help? ...Read more
Not likely: Most intracranial vascular anomalies, including aneurysms, require IV contrast to be seen on ct head. However, ct without contrast is 90% sensitive for intracranial bleeding. The risks of IV contrast for ct include kidney injury and allergy to contrast dye. Good luck! ...Read more
CT Brain shows mass prepontine cistern CPA meningioma. Symptoms consistent with diagnosis. MRI contrast show no lesion. Symptoms persist! Now what?
Very strange: Not certain what to make of the disparity between the CT scan and the MRI. In some cases, a lesion is so small that it is missed by the artifact created by the thickness of the MRI slices. I would ask your doctor if an MRI of the brainstem with "thin slices" might be reasonable to confirm/refute the CT--with and without contrast. Take care and stay healthy! ...Read more
Radiology/neurology. Ct scan shows bone, MRI shows soft tissue, so therefore can't indentify disease of skull bones. Intercrainial means misdiagnosis?
maybe: A large pituitary tumor, or macroadenoma, may be large enough to be visible on ct, but a small pituuitary tumor, or microadenoma, will probably not be visible. An MRI (without and with contrast) of the pituitary is the preferred method to evaluate this structure. ...Read moreSee 1 more doctor answer

First ct scan diverticulitis thought he had fistula. Second Ct scan radiologist said no fistula bowel thickening maybe sigmoid abscess ct be wrong?
Not necessarily: The interpretation of the same ct scan can be changed according to the clinical picture. The clinical picture has support the ct scan and until it would the reading of the ct scan can change. So, it is a fluid situation , it is not rigid. Reading of the ct has to match the clinical condition of the person. I hope this helps. ...Read more
