The Administration Of Contrast Media

made, are in the studies of medicine/treatment. And to be specific, the study of radiology.

Advances in both radiography and radiation treatment keep on advancing and get to be more sophisticated. Cases incorporate digital subtraction angiography (DSA) in which, apparently, there is the potential for more prominent inclusion by radiographers and by radiation therapists in image guided radiation treatment. Looking even to the moderately later past underscores the degree to which change is happening in the radiography and radiation treatment work environment. Case in point, ten years prior it was radiologists who embedded cannulas for CT patients (AIR 2014, 1). Presently radiographers and attendants attempt the assignment. In private radiology hones, Australian radiographers now consistently embed central lines and do feature joint, shoulder, arm, and tendon infusions under supervision.

The contrast dye that is used during cardiac catheterization can lead to many reactions that ranges from mild to serious. The mild symptoms include diaphoresis, pruritus, dyspnea and tachycardia. The more serious reactions include ventricular tachycardia, bronchospasm, laryngeal edema, and seizures (Siddiqi, 2014). A nurse can minimize these risks by pre-medicating the patient if the patient is known to have an allergy or a disease that could exacerbate such as asthma. The medications that can be used include prednisone and hydrocortisone. It is also recommended that the

One of another main reason for all the irregularities during the procedure occur mainly due to the confusion of communication between the radiographer and the surgeon because of a formal language is not being used in order to operate the fluoroscopy (Suhm et al., 2003 ).This creates a confusion and loss of crucial time which eventually leads to numerous position adjustments, while doing so the radiographer had to expose the patient several times before the desired position can be obtained which can prove to be serious threat depending upon the nature of patient as exposure to radiation differs depending upon the nature and status of a patient.

The contrast administration is determined either by the hospital protocol or the physician. It also depends on the type of test and/or the anatomy of the patient that is to be examined. The facility where I work at, perform two kinds of IV contrast studies and those studies are dependent on the need and/or condition of the patient. It is the job of the technologist to screen the patient to determine the type of contrast to be used.

Contrast is directly related to the illumination system and can be adjusted by changing the intensity of the light and the diaphragm. Chemical stains applied to the specimen can also enhance contrast elements (Alonzo p56)

Reactions from contrast dyes can be sensed as soon as one minute of injecting the dye and can go as long as several days before ever becoming known to the patient or the doctor 1. Hypersensitivity can also be mistaken as an allergic reaction in some patients. When a patient is hypersensitive they can show signs of allergic reactions that are not as severe as a normal allergic reaction. Contrast dyes are broken down into two categories, high-osmolar and low-osmolar. High-osmolar dye is an ionic dye with particles that dissociate in solution while the low-osmolar dyes are nonionic and do not dissociate in the solution2. In some cases the physician or radiologist may see that a contrast media is not necessary and can determine to go without it. If a contrast dye is needed to see the specified image clearly then a low-osmolar dose maybe given to the patient and it is recommended that all patients stay in the department 20-30 minutes after an injection to watch for acute or severe reactions 2. In some cases a medication can be given before the contrast media to help combat the reactions a patient may have experienced

Dynamic contrast. Dynamic contrast refers to a combination of different sensations in the same food. In the words of Witherly, foods with dynamic contrast have “an edible shell that goes crunch followed by something soft or creamy and full of taste-active compounds. This rule applies to a variety of our favorite food structures — the caramelized top of a creme brulee, a slice of pizza, or an Oreo cookie — the brain finds crunching through something like this very novel and thrilling.”

There are not any gasps in the knowledge base and the author seems to be well informed about communication in radiography, from first view the content of abstract is well organised with clear rationale aims to perform a qualitative study (Bassett,2004).

If you have thought about becoming a Radiologic Technologist, someone who performs imaging examinations, but do not know if it is the right choice for you. This paper will inform the reader as to how to become a Radiologic Technologist, their job description, ranging from the work settings to the kind of patients they deal with, some of the challenges and rewards, including their salary as well. At the end of this paper you should be able to make up your mind on becoming one or not.

Using of contrast agent in children is generally safe. For example, in the used of ultrasound contrast agents for IV applications in children, the total number of patients they had adverse effect is about 2%, and there is only 1 sever anaphylactic shock and 9 mild transit adverse effects. The most common target organ that may get effected by the contrast agents is the liver.

DSA is not only a diagnostic procedure, it also provides ways to treat the issue in real-time. It has a higher spatial and temporal resolution and permits the visualization of a large amount of collaterals, which can be difficulty in other modalities. The digital subtraction technique also reduce the dose of contrast demanded. However, DSA is time-consuming, is not widely available, once that it requires more professionals to do the procedure than in CTA or MRA and it has the same problems regarding the use of contrast and radiation exposure. Those aspects bring to discussion if the high quality of the image outweigh the drawbacks of the procedure (Al-Qaisi,

Ideally, before this procedure the patient would have been advised to fast in the period prior the scan, particularly if a contrast material was being used to avoid any adverse reactions. However as this was an emergency situation, previous fasting may not have been possible giving the circumstances. Contrast materials may be administered orally or via intravenously (IV) to provide a contrast throughout the scan. Having removed any metal jewelry the patient would be asked to lie flat on their back on the scanning table, which would then move through the scanner quickly to determine the best position to perform the scan. Once positioned correctly on the table the patient would be advised to stay still and try to hold their breath as the table moved through the scanner allowing the CT scan to be

Contrast is related to the illumination system and can be adjusted by changing the intensity of the light and the diaphragm/pinhole aperture. Chemical stains applied to the specimen can also enhance contrast.
