Intravenous Pyelogram Ivp
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

An ivp allows the radiologist to view and assess the anatomy and function of the kidneys, ureters and the bladder. ...Read moreSee 1 more doctor answer
Many things: In general areas of abnormal growth such as a tumor or fluid cyst, or areas of swelling such as inflammation or infection. The intravenous contrast solution and swallowed barium help the radiologist identify and separate nearby structures and organs, and help to better visualize possible abnormalities. ...Read more
Needs evaluation: Rarely contrast dye can knock loose some intravascular deposits which can lodge in narrow vessels and change the function of the part supplied. This has been reported rarely with the ophthalmic vascular supply. Have you ophthalmologist see this immediately to determine the cause. ...Read moreSee 1 more doctor answer
Possible : The IV contrast provides imaging of blood flow into kidneys and will detect blockages, aneurysms, asymmetric flow, mass, structural problems. Lab draw and renal panel provide functional information on how your kidneys are performing as filters. Your doc will want to follow up with you after all the studies are complete to give you results. The IV contrast itself can be damaging to your kidney. ...Read moreSee 1 more doctor answer

Radionuclide angiography is a nujclear scan (muga scan) used to assess pumping function of the heart. Catheterization is an invasive procedure and muga scan is non-invasive procedure with minimal risk. ...Read more
depends: Acute appendicitis can be diagnosed with good accuracy by history, physical exam, ultrasound, and non-contrast ct scan of abd/pelvis. Now is some cases, where exam, history and other imaging is not diagnostic and observation of the patient with a surgeon is not possible, more sophisticated imaging, contrasted ct can help. Be well. ...Read more
