IR - MIDTERM (Clinical Application & Angiography) Flashcards
It refers to the practical use of IR techniques and procedures to diagnose, treat, or manage various medical conditions
Clinical Application
This involves using techniques like nerve blocks or vertebroplasty to manage pain, particularly in conditions like chronic back pain or cancer-related pain
Pain Management
Clinical applications in IR encompass a wide range of procedures which includes but are not limited to (6):
- Vascular Interventions
- Oncology
- Biliary Interventions
- Pain Management
- Urological Procedures
- Gastrointestinal Interventions
Which typical imaging modalities are involved in IR (4):
- X-rays
- CT Scans
- Ultrasound
- MRI
This encompass angioplasty, stent placement, and embolization to treat conditions like arterial blockages, aneurysms, or bleeding.
Vascular Interventions
This entails biliary stenting for obstructed bile ducts or drainage of bile in conditions like cholangiocarcinoma.
Biliary Interventions
This covers tumor ablation (e.g., radiofrequency ablation or
microwave ablation), biopsy, and palliative treatments for cancers.
Oncology
This integrates the likes of nephrostomy tube placement,
drainage of renal abscesses, or prostate artery embolization
Urological Procedures
This is the placement of feeding tubes (e.g., PEG tube), drainage of abscesses, or variceal embolization for portal hypertension.
Gastrointestinal Interventions
A medical imaging technique used to visualize the inside or lumen of blood vessels and organs of the body, particularly in the arteries, veins, and heart chambers
Angiography
Angiography is also known as ______
Arteriography
This is a type of angiography involving the injection of a contrast dye into the blood vessels commonly used to assess coronary arteries, peripheral arteries, and brain blood vessels
X-ray Angiography (Conventional Angiography)
This is similar to CTA but uses magnetic resonance imaging to generate detailed images of blood vessels for vascular conditions in the brain and other parts of the body.
MR Angiography (MRA)
A non-invasive method using a CT scan and a contrast dye to obtain detailed 3D images of blood vessels. It is often used to look at arteries in the brain, heart, or limbs.
CT Angiography (CTA)
A more advanced form of X-ray angiography that uses digital technology to subtract background images, providing clearer images of blood vessels.
Digital Subtraction Angiography
DSA is considered as the ______procedure in IR
Gold Standard
A diagnostic test that uses an X
ray to produce an image that can help the doctor find blockages or other abnormalities in the blood vessels of the head and neck that may lead to a stroke or bleeding in the brain.
Cerebral Angiography
Cerebral Angiography can help in diagnosing (7):
- Aneurysm
- Atherosclerosis
- Arteriovenous Malformation
- Vasculitis
- Brain Tumors
- Blood Clots
- Tears in the Lining of an Artery
What risk may occur if a catheter loosens plaque inside a blood vessel during cerebral angiography ?
Stroke
Blood clots may form around the catheter _____
Tip
It is an x-ray of the blood vessels that supply the lungs
Pulmonary Angiography
This pertains to blood clot in the blood vessels of the lungs
Pulmonary Embolism
It is an angiogram that looks at the blood vessels of the belly to check blood flow to the organs of the ____ such as the liver and the spleen
Abdominal Angiography
What is the term for spasms of the blood vessels ?
Vasospasm
