Study Notes
X-Ray Tissue Appearance
- Bone appears white on a conventional x-ray.
Chest X-ray Use
- Pneumonia, lung cancer, heart failure, and fractured ribs are some reasons for a chest x-ray.
Ultrasound Imaging
- Muscles, tendons, organs, blood vessels, fetal development, and heart conditions can be visualized using ultrasound
Ultrasound "Echo"
- Echo in ultrasound refers to the reflection of sound waves from tissues.
Radiography Contrast Medium
- Contrast agents are used in radiographic examinations to improve the visibility of specific structures.
CT vs. Conventional X-ray
- CT scans produce 3D images, while conventional x-rays create 2D images.
Magnetic Resonance Imaging (MRI) Disadvantages
- Claustrophobia can be an issue during MRI scans.
- Patients with metal implants may not be able to undergo an MRI.
- Expensive compared to other imaging techniques.
Positron Emission Tomography (PET) Images
- PET produces images based on the distribution of a radioactive tracer.
Endoscopy Risks
- Bleeding is a major risk associated with endoscopy.
Fiberoptic Scope Characteristics
- Thin and flexible
- Contain a light source
- Allow for direct visualization
- Transmit images to a monitor
Endoscopy Advantage
- Endoscopy allows for direct visualization of internal organs and can be used for biopsy.
X-ray Rib Visibility
- Ribs appear white on a chest x-ray because they are dense.
Contrast Medium Monitoring
- Kidney function, allergic reactions, and contrast extravasation are adverse events that require monitoring when using contrast medium.
Soft Tissue X-ray Diagnosis
- Soft tissues, such as muscles and ligaments, are difficult to diagnose on an x-ray because they are radiolucent (appear darker than bone).
X-Ray vs. CT Scan Diagnosis
- CT scans provide more detailed information than conventional x-rays and can detect subtle abnormalities.
MRI Contraindication
- Patients with pacemakers should not get an MRI.
Positron Emission Tomography (PET) Statement
- PET can detect metabolic activity, such as cancer cells, making it useful for early disease detection.
PET Disease Detection
- PET scans can detect disease earlier because they visualize metabolic activity rather than just anatomical structures.
Endoscopy Uniqueness
- Endoscopy allows direct visualization of internal organs, making it unique compared to other imaging techniques.
Cystoscopy Examined Anatomy
- Cystoscopy examines the bladder and urethra.
Persistent Cough Endoscopy
- Bronchoscopy would be performed on a patient with a persistent cough.
