However, there are no absolute contraindications to iodinated contrast, so the benefits needs to be weighted against the risks. [14] As with CT scans in general, the radiation dose can potentially increase the risk of radiation-induced cancer. The injection of iodinated contrast agents may sometimes lead to its extravasation. [15]
Iodinated contrast. Contrast CT of a patient with brain metastases from breast cancer, before (left) and after (right) injection of iodinated contrast. Iodinated contrast is a form of water-soluble, intravenous radiocontrast agent containing iodine, which enhances the visibility of vascular structures and organs during radiographic procedures.
Iodinated contrast contains iodine.It is the main type of radiocontrast used for intravenous administration.Iodine has a particular advantage as a contrast agent for radiography because its innermost electron ("k-shell") binding energy is 33.2 keV, similar to the average energy of x-rays used in diagnostic radiography.
Pyelogram (or pyelography or urography) is a form of imaging of the renal pelvis and ureter. [1] Types include: Intravenous pyelogram – In which a contrast solution is introduced through a vein into the circulatory system. Retrograde pyelogram – Any pyelogram in which contrast medium is introduced from the lower urinary tract and flows ...
Computed tomography angiography (also called CT angiography or CTA) is a computed tomography technique used for angiography —the visualization of arteries and veins —throughout the human body. Using contrast injected into the blood vessels, images are created to look for blockages, aneurysms (dilations of walls), dissections (tearing of ...
A computed tomography scan (CT scan; formerly called computed axial tomography scan or CAT scan) is a medical imaging technique used to obtain detailed internal images of the body. [2] The personnel that perform CT scans are called radiographers or radiology technologists. [3][4]
Photon-counting computed tomography. Photon-counting computed tomography (PCCT) is a form of X-ray computed tomography (CT) in which X-rays are detected using a photon-counting detector (PCD) which registers the interactions of individual photons. By keeping track of the deposited energy in each interaction, the detector pixels of a PCD each ...
Diatrizoate. Diatrizoate, also known as amidotrizoate, Gastrografin, is a contrast agent used during X-ray imaging. [1] This includes visualizing veins, the urinary system, spleen, and joints, as well as computer tomography (CT scan). [1] It is given by mouth, injection into a vein, injection into the bladder, through a nasogastric tube, or ...
