There is some radiation involved but it is considered much less "invasive" and has less complications than the regular type of "angiogram", where blood vessels are visualized by inserting thin tubes called catheters directly into them to inject a dye. ...Read more

Do MRI scans usually require an injection of contrast?

Do MRI scans usually require an injection of contrast?

Depends on diagnosis: Usually MRI scans of the spine and joints (shoulder, knees, etc) do not need a contrast injection. Contrast is given for spine MRI scans to search for tumors and postoperative scarring. Mri scans of the brain, abdomen, pelvis can be performed with a contrast injection to help find a tumor, but these scans can also be performed without injection. Breast MRI should be performed with contrast. ...Read more

How is an intravenous pyelogram actually performed?

How is an intravenous pyelogram actually performed?

By injecting dye: When a contrast material is injected into a vein in the patient's arm, it travels through the blood stream and collects in the kidneys and urinary tract, turning these areas bright white on the x-ray images. An ivp allows the radiologist to view and assess the anatomy and function of the kidneys, ureters and the bladder. ...Read more

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

It is a CT myelogram: except that you are tilted feet up/head down so that gravity allows the contrast to get into the brain cisterns from the spinal thecal sac. The injection is the same. So, it is a CT myelogram with the addition of an extra manuever and an extra scan. ...Read more

Which procedure does a lung perfusion scan involve?

Which procedure does a lung perfusion scan involve?

Inject radioactive: A perfusion lung scan is done by injectecting a low-dose radioactive tracer into a vein and taking images showing where blood flow is going in the lungs. It is used to diagnose pulmonary embolism (blood clot to the lungs). The test is safe and generally free of any side effects. It is used less often now than ct angiogram, but is safer and involves less radiation exposure. ...Read more
