Unlocking the Marvels of CT Scans: A Heartwarming Guide for Easy Understanding
- 1. COMPUTED TOMOGRAPHY CT SCAN Meow!~ BY: PURR NURSE
- 2. COMPUTED TOMOGRAPHY ↓ PROCESS OF COMPUTING ↓ TOMOS ↓ a cut or a slice ↓ GRAPHIA ↓ Process of “writing” Or “recording” - Medical Imaging Technique - Combines: Computer Processing with Xray Technology - To Create: Detailed Cross Sectional Images
- 3. • Detect: (1) Brain Contusion Bruising ↓ - Bruising to Brain Tissue - Caused: Direct Impact Force to the head COMPUTED TOMOGRAPHY (CT SCAN)
- 4. • Detect: (2) Brain Calcification ↓ CALCIUM ↓ TO MAKE Presence of Calcium in Brain Tissues COMPUTED TOMOGRAPHY (CT SCAN)
- 5. • Detect: (3) Cerebral Atrophy BRAIN LACK OF NOURISHMENT OR WASTING AWAY ↓ ↓ Brain Tissue Decrease in Size ↓ → 1. Age 2. Neurodegenerative Disease 3. Pathological Conditions affecting the brain COMPUTED TOMOGRAPHY (CT SCAN)
- 6. NEURODEGENERATIVE ↓ ↓ NERVE “DOWN FROM” OR “AWAY FROM” “TO GENERATE” OR “TO PRODUCE” ↓ ↓ - Occur: When nerve cells in the brain or peripheral nervous system lose function over time and ultimately die
- 7. PATHOLOGICAL CONDITIONS AFFECTING THE BRAIN PATHOLOGICAL ↓ ↓ PATHOS ↓ Suffering or Disease LOGOS ↓ Study or Science AFFECTING THE BRAIN ↓ Study of a Disease Affecting The Brain
- 8. Example of NEURODEGENERATIVE DISEASES and PATHOLOGICAL CONDITIONS AFFECTING THE BRAIN: NEURODEGENERATIVE DISEASES PATHOLOGICAL CONDITIONS AFFECTING THE BRAIN Alzheimer's disease Traumatic Brain Injury (TBI) Parkinson's disease Stroke Huntington's disease Brain Tumors Amyotrophic Lateral Sclerosis (ALS) Meningitis Multiple Sclerosis (MS) Brain Abscess Frontotemporal Dementia (FTD) Encephalitis Prion diseases Hydrocephalus Spinocerebellar Ataxias Cerebral Aneurysm
- 9. • Detect: (4) Hydrocephalus ↓ WATER ↓ HEAD ↓ Water on the Brain ↓ Cerebrospinal fluid (CSF) CEREBROSPINAL FLUID (CSF) - clear, colourless fluid that surrounds and bathes the central nervous system, including the brain and spinal cord. - While it is often described as "clear" and "water-like," CSF is not pure water. - It is a complex fluid composed of water, electrolytes, proteins, glucose, and other substances. COMPUTED TOMOGRAPHY (CT SCAN)
- 11. • Detect: (5) Inflammation or ENCEPHALITIS ↓ BRAIN ↓ INFLAMMATION ↓ INFLAMMATION IN THE BRAIN → COMPUTED TOMOGRAPHY (CT SCAN)
- 12. • Detect: (6) Space occupying lesions: Tumors Hematomas Edema Abscesses Vascular Anomalities COMPUTED TOMOGRAPHY (CT SCAN)
- 13. CT SCAN IMAGES: COMPUTED TOMOGRAPHY (CT SCAN) - Provide: (1) Cross sectional views of the brain (2) Distinguishing differences in tissues, densities of the skull, cortex, subcortical structures, and ventricles.
- 14. NURSING CONSIDERATIONS IN COMPUTED TOMOGRAPHY (CT SCAN) • Confirm: Patient is not allergic to iodine or shellfish. BEFORE CT SCAN: WE USE CONTRAST AGENT contains MISCONCEPTION ALLERGIC: SHELLFISH = IODINE NOT TRUE! PRESENCE OF IODINE NOT IODINE ITSELF Allergens: Protein
- 15. → As a nursing consideration, it is essential for healthcare providers to inquire about any known allergies, including shellfish allergies, before performing a CT scan with contrast. This information helps the medical team make informed decisions about the type of contrast agent to use or whether alternative imaging approaches are necessary to ensure patient safety. If there are concerns about allergies, healthcare providers may take additional precautions or conduct further testing as needed. NURSING CONSIDERATIONS IN COMPUTED TOMOGRAPHY (CT SCAN)
- 16. • A review of relaxation techniques for claustrophobia • If with contrast medium, tell the patient that it’s injected into an existing I.V. line or that a new line may be inserted • A period of Fasting (usually 4 hours) is required prior to the study • Evaluation of Renal Function- due to injected of dye; this needs to be excreted NURSING CONSIDERATIONS IN COMPUTED TOMOGRAPHY (CT SCAN)
- 17. • Feel Flushed or notice a metallic taste in his mouth when contrast medium is injected • Educating the patient about the need to lie quietly throughout the procedure NURSING CONSIDERATIONS IN COMPUTED TOMOGRAPHY (CT SCAN)
