  2. Contrast CT - Wikipedia

    en.wikipedia.org/wiki/Contrast_CT

    A small bolus of radio-opaque contrast media is injected into a patient via a peripheral intravenous cannula. Depending on the vessel being imaged, the volume of contrast is tracked using a region of interest (abbreviated "R.O.I.") at a certain level and then followed by the CT scanner once it reaches this level. Images are acquired at a rate ...

  3. CT pulmonary angiogram - Wikipedia

    en.wikipedia.org/wiki/CT_pulmonary_angiogram

    An intravenous cannula is required for the administration of iodinated contrast. The typical dose is 30-40 g of iodine (corresponding to 20–30 cc of 370 mg/ml iodine solution). [10] However, for patients at high risk of contrast-induced nephropathy, it is possible to reduce the required amount of contrast using dual energy CT.

  4. Computed tomography angiography - Wikipedia

    en.wikipedia.org/wiki/Computed_tomography...

    A reaction may occur whenever iodine contrast is injected. These reactions range in severity and it is difficult to predict if they will occur. With the current practice of using low-osmolar contrast these adverse reactions only occur in ~0.1% of cases. [4] The severity of the reaction can be broken down into three groups:

  5. Port (medicine) - Wikipedia

    en.wikipedia.org/wiki/Port_(medicine)

    In those with contrast allergy, or allergy to food or medications, the procedure can still be carried out with prednisolone coverage. Other relative contraindications include coagulopathy (abnormal coagulation) or platelet count less than 50x10 9 /L. However, if the port is needed urgently, platelet transfusion may be given while the procedure ...

  6. Iodinated contrast - Wikipedia

    en.wikipedia.org/wiki/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.

  7. Emergency ultrasound - Wikipedia

    en.wikipedia.org/wiki/Emergency_ultrasound

    A portable ultrasound machine used in the prehospital setting. Emergency ultrasound is used to quickly diagnose a limited set of injuries or pathologic conditions, [4] specifically those where conventional diagnostic methods would either take too long or would introduce greater risk to a person (either by transporting the person away from the most closely monitored setting, or exposing them to ...

  8. Radiocontrast agent - Wikipedia

    en.wikipedia.org/wiki/Radiocontrast_agent

    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.

  9. WHO Surgical Safety Checklist - Wikipedia

    en.wikipedia.org/wiki/WHO_Surgical_Safety_Checklist

    The Global Initiative for Emergency and Essential Surgical Care [7] and the Guidelines for Essential Trauma Care [8] focused on access and quality. In 2005, WHO Patient Safety began issuing Global Patient Safety Challenges, which bring together teams of specialists in order to put together clinical guidelines and tools for research that address ...
