Importance of a CT machine in the medical field

Specific Purpose:  To inform my audience about the importance of a CT scan.

Central Idea: To have my classmates understand the importance and uses of a CT scan. Have the class leave today with more knowledge of how the benefits will outweigh the risks when it comes to computed tomography imaging.

Introduction: 

My name is Christopher Garrity and I am looking to pursue a career in the medical field. I have been working at St. Francis hospital in Roslyn, New York for roughly nine months. I currently work for the radiology department where I am a CT technologist assistant. Through this speech I am here to inform you about the importance of a CT machine and some of its uses. Through this presentation we will cover a small history of the machine origin, different scans which can be performed, as well as the importance of contrast administered by a CT technologist which yields more precise results. On a standard day working for radiology, myself and a CT technologist will be working to complete these scans in a timely fashion. While every scan we complete holds an importance to one of our patients, there are emergencies which occur and take precedence over the others and I would like to give an example with a story. This includes a code which is announced over the loudspeaker called “Neuro RRT” followed by the location of the patient. This code is determined by an employee at the hospital who has suspicion that a patient is suffering from a stroke. When this occurs, myself and the technologist will work diligently to complete whatever scan is on the table and have the room cleared and prepared for the patient which will be rushed down to our department. When this code is called a team of employees who make up our stroke response team will all come to our office very quickly, to assess the patient and speak with the radiologist as well as a neurologist to determine a plan of which steps to take to ensure the patients wellbeing.

Body:

I.         A background and history of CT scanning. 

                  A.   Invented in 1972 by British engineer Godfrey Hounsfield and Allan Cormack.

B.   Both individuals received the Nobel peace prize for their contributions to medicine.

C. CT scan is abbreviated for Computed Tomography Imaging.

D. CT is a combination of many x-ray images taken from different angles to produce cross sectional images.

                 

      II.       Different scans performed.

A.    Head

1. Can rule out skull fractures, internal bleeding, brain tumors, stroke, aneurysm.

B.     Abdomen and Pelvis.

1.      Can rule out issues such as colon cancer, diverticulitis, appendicitis or an abscess in the abdomen.

C.     Angiography

1.      Uses IV contrast which highlights your vessels.

2.      Used to examine your vessels throughout the body.

3.      Can detect a thrombus such as a PE.

4.      Used to detect aneurysms.

D.    Spine

1.      Detect herniated discs.

2.      Compare the spine before and after surgery

3.      Can detect tumors in the vertebral column.

III.       The uses of IV and Oral contrast

A.    Intravenous contrast

1.      Administered through an IV

2.      Labs must come back with normal kidney function to administer this contrast

3.      Two types of contrast we use are Visipaque and Omnipaque.

4.      The iodine in this contrast will highlight the vessels to look for any obstructions or thrombus.

B.     PO (Oral contrast)

1.      Two drinks will be administered two hours before the exam.

2.      Used to highlight areas of the GI tract in the Abdomen and Pelvis.

3.      Oral contrast takes at least 90 minutes to fully pass through the GI tract.

4.      Can be used for any issues which stem for abdominal pain such as diverticulitis and appendicitis.

       Conclusion:

            As a result, we have reviewed many of the main points when referring to CT scans used in the healthcare field. These scans have become very crucial when diagnosing patients with a variety of different diseases and have improved healthcare tremendously within the past 50 years. As technology continues to grow, we see more and more examples of how machines such as computed tomography helps to increase longevity.

Life In Ancient Greece

As we know, Ancient Greek life was very different then life today. The world was not modernized and industrialized the way it is now. In Ancient Greece, individuals worked hard every day to feed themselves and to obtain goods that are necessary for every day survival. Another important part of life during this time was theatre. Theatre was one of the only forms of entertainment for people and it was also a place where many gathered to socialize. Here is an excerpt on ancient Greek life.
"Men if they were not training in military, or discussing politics they went to the Theatre for entertainment. To watch dramas that they could relate to, including tragedies and comedies. These often involved current politics and gods in some form. It is thought that women were not allowed to watch theatre or perform at the theatre, although male actors did play women roles.
Lives of Women in Ancient Greece were closely tied to domestic work, spinning, weaving and other domestic duties. They were not involved in public life or in politics. The live were normally quite confined to the house although one public duty was acting as a priestess at a temple.
Children in ancient Greece usually occupied their time playing with toys and games." (Ancient Greek)

Spohocles Life

"Born in 495 B.C. about a mile northwest of Athens, Sophocles was to become one of the great playwrights of the golden age. The son of a wealthy merchant, he would enjoy all the comforts of a thriving Greek empire. He studied all of the arts. By the age of sixteen, he was already known for his beauty and grace and was chosen to lead a choir of boys at a celebration of the victory of Salamis. Twelve years later, his studies complete, he was ready to compete in the City Dionysia--a festival held every year at the Theatre of Dionysus in which new plays were presented.
In his first competition, Sophocles took first prize--defeating none other than Aeschylus himself. More than 120 plays were to follow. He would go on to win eighteen first prizes, and he would never fail to take at least second......Of Sophocles' more than 120 plays, only seven have survived in their entirety. Of these, Oedipus the King is generally considered his greatest work. This tragedy of fate explores the depths of modern psycho-analysis as Oedipus unwittingly kills his father and marries his mother in an attempt to avoid the very prophecy he ultimately fulfills." (Sophocles)

Oedipus Rex Summary

   Oedipus Rex is a greek tragedy written by Sophocles. To begin the play a plague has stricken the city of Thebes. Oedipus, the king of Thebes ordered his brother - in - law Creon to visit an oracle to find out how to help the city. The oracle stated that the plague will end when the murderer of King Laius is found and dismissed. To find out more about the murder oedipus sent out for the blind prophet Tiresias. Oedipus did not want to believe Tiresias that he was the one who had killed king Laius, so Oedipus accuses Creon and Tiresias of conspiring against his life, and charged Tiresias with insanity. Now angered before leaving the stage, Tiresias left Oedipus with one more riddle saying that the murderer of Laius will turn out to be both father and brother to his own children, and the son of his own wife. Soon after Tiresias leaves Oedipus' wife Jocasta helped explain the murder of King Laius to him to help solve the mistery. After hearing about his death, Oedipus believes that he could be the murderer of Laius. After calling upon a local shepherd he is informed that he was the son of Laius and that he was sent to be killed as a new born child. He had also come to realize that he also was the murderer of his father and the husband of his own mother! Realizing who he is and who his parents are Oedipus flees the scene while gouging his own eyes out. While bleeding he begs to be exiled and asks Creon to take care of his young children.
