Quiz 2 - AP 2

Cardiovascular Interventional Radiography - Lecture 1

QuestionAnswer
A Radiographic examination of vascular structures within the body Angiography
Characteristics of Angiography include: 1. 2. 3. 1. Invasive Procedure 2. Labor intensive exam 3. Greater cost traditional radiologic exams
What was the year that the first radiograph was done that demonstrated blood vessels? 1896
What was used as contrast material when radiograph of blood vessels was first introduced A thick emulsion of chalk
Up until 1950's what was the approach called that injected contrast through a needle directly into the blood vessel or through a catheter that was passed into the body surgically exposing the blood vessel? The Direct Approach
In 1952, what approach was developed by Seldinger, a swedish Radiologist, whose technique allowed for indirect insertion of the catheter? The Seldinger approach
What did the Seldinger approach eliminate? Surgical risk
Early angiograms consisted of ______ images single
Device that allowed for many images to be taken to demonstrate the flow of contrast through the vessels? Serial filming devices
Examples of Serial Filming devices: 1. 2. 3. 4. 1. Rapid film changers 2. Cine film devices 3. Cassette changers 4. Digital serial filming
Development of Power or Mechanical injections allowed for? More rapid and precise control of contrast material rates and volumes
What type of injection involves placing catheter tip into orifice of specific artery? Section injection (less dilution, limits superimposition)
Types of procedures that determine the condition of the vascular system? Diagnostic procedures
An invasive procedure, which is a non-surgical method to correct a condition that has been previously diagnosed - can be vascular or non-vascular? Interventional procedures
System that allows visualization of the vascular structures - Records of flowing contrast medium in a series of images vs single film Rapid film changer system
The most significant imaging component which establishes the exposure rate or speed Program Selector
What are the 3 Programming phases on the Program Selector: Fastest, slower, slowest
What does the Fastest Programming phase in the program selector demonstrate? Demonstrates contrast filled arteries
What does the Slower Programming phase, in the program selector, demonstrate? Demonstrates contrast filled veins
What does the Slowest Programming phase in the program selector demonstrate? Used to demonstrate delayed filling of tumors
A mechanical device used to inject contrast into the circulatory system? Automatic Injector
Name of the Regulator that allows injection to be accelerated over a specific period of time - reduces catheter whip, termed linear rise Accelerator regulator
What sets the maximum pressures to be generated during the injection? Pressure limiting device
The delivery flow rate is also the? Injector flow rate
Guidewires harder to advance in the cardiovascular procedures? Straight guidewires vs. curved
Two methods used to introduce a catheter into the body 1. Direct Stick 2. Seldinger
Needle is placed in what Artery for the procedure (Angioplasty) Femoral Artery
What position is the patient placed for Angiography? Supine on the table
What technique is used to insert the catheter for and Angiography procedure? Seldinger
Patient may be required to rest in the supine position for how long observe for bleeding and hematoma? up to 12 hours
After an Angiography procedure, how long until the patient may resume normal activity? After 24 hours
The Circulatory system is composed of what two systems? Lymphatic and Cardiovascular
The Lymphatic system includes: Lymph, lymph vessels, lymph nodes
The Cardiovascular system includes: Heart and vessels
Pulmonary means? Lungs
Systemic means? Body
Cardio means? Heart
Vascular means? Vessels
The Lymphatic System is composed of an elaborate arrangement of ______ ______ closed vessels
The Lymphatic system serves as a what? A drainage system for tissue fluids and wastes
Functions of the Lymph System include: 1 2 3 4 1. removes impurities from the blood 2. produces anti-bodies 3. return collected fluid to the vascular system
What is lymph? A clear watery substance
Cardiovascular System Functions: 1 2 3 1. Transport oxygen, nutrients, hormones and chemicals for necessary body activity 2. Remove waste products through kidneys and lungs 3. Maintains body temperature, water and electrolyte balance
The vascular system is broken down into what two systems? Pulmonary and Systemic
Pertaining to the circulation of blood within the heart and Lungs? Pulmonary system
Pertaining to circulation within the blood vessels? Systemic system
Popular Radiology sets
