VISUAL EXAMINATIONS USED IN RADIOLOGY-LESSON 135
VISUAL EXAMINATIONS USED IN RADIOLOGY: The radiopaque studies may create some side effects in some patients as the radiopaque substance contains iodine contrast materials. The side effects may be of some bland reactions for instance redness of the skin, queasiness, warmth or itchiness sensations, and sometimes may be serious reactions like spasm in the airway, hives, swelling of the larynx, vasodilation, and rapid heart rate etc., Management of this situation is immediate fixing of ventilation followed by injections of adrenaline and corticosteroids or any antihistamine injection.
When the patient is prone to allergic reactions some other studies like fluoroscopy, tomography, and MRI or magnetic resonance imaging are used. We will see about these procedures one by one.
Using this visual exam method three views such as sagittal or anteroposterior; coronal or frontal, and axial or cross-sectional images can be taken. No radioactive material is used as a medium in this study. The science of MRI scanning is the magnetic field of the nuclei of atoms like hydrogen in the water is used to create a magnetic field inside the body organs naturally by applying a large magnetic field from externally.
MRI is very useful in identifying tumors in the brain, spinal cord images, tumors in the chest and abdomen, and also in the visual examination of the heart and its valves.
In the next post we will study about ultrasound and MRI scans. Okay.
Come on.
