Ct scan, mri, nuclear medicine imaging, ivp scan, how are they different?

Ct scan, mri, nuclear medicine imaging, ivp scan, how are they different?

Quite different: Ct involves xray type radiation with cross sectional imaging in transaxial, sagittal, and coronal projections. Nuclear medicine, internal irradiation either injected intravenously, inhaled, ingested, injected subcutaneously.Ivp uses injection of contrast material for visualization of kidneys and bladder with x-ray. Mr imaging uses no ionizing radiation magnetic fields to generate x-sectional images. ...Read more

Will MRI scans show cancer?

Will MRI scans show cancer?

Depends: Mri is very good at showing abnormal tissue from normal tissues and can pick up various cancers very well. Some cancers, however, can be small and not well seen on mri. Some may be better seen on ct. Cancers involve in the stomach and colon are usually not well seen and may require endoscopy or colonscopy. Some breast cancers are also better seen on mammograms than mri. ...Read more
