Study Notes
Radiologic Modalities
- Radiology modalities are used to identify medical conditions like bone fractures, cancers, and cardiovascular disease.
- Radiology modalities offer a wide range of images for radiologists to examine.
Ultrasound
- Ultrasound uses soundwaves to create images of the body's organs, tissues, and structures.
- Ultrasound gel is made of water and propylene glycol.
- Ultrasound is also called ultrasonography or sonography.
- Ultrasound uses sound waves instead of radiation, making it safe for its user.
- Ultrasound is non-invasive.
X-Ray
- X-rays are used to create images of internal structures, such as bones and organs.
- X-rays help diagnose fractures, infections, and diseases like pneumonia.
- X-ray scanners are used to inspect luggage and cargo for security threats.
- X-ray telescopes are used to observe celestial objects and phenomena, such as black holes, neutron stars, and supernovae.
- X-ray fluoroscopy provides real-time imaging, useful for surgeries and procedures.
- X-ray equipment is available in most hospitals, clinics, and dental offices.
- X-rays are a fast and accurate diagnostic tool, especially in emergency situations.
- X-rays can be used to inspect materials and products without causing damage.
Mammography
- Mammography uses low-dose X-rays to examine the breast.
- Mammography's primary use is in breast health and cancer screening.
- Mammography is used to detect early signs of breast cancer in asymptomatic women.
- Diagnostic mammograms help evaluate breast tissue and guide further investigation.
- Mammograms can monitor changes in breast conditions like cysts or calcifications over time.
- Mammograms can identify small tumors that may not be felt during a physical breast exam.
Magnetic Resonance Imaging (MRI)
- MRI uses strong magnetic fields and radio waves to create detailed images of internal structures.
- MRI is commonly used to examine the brain and spinal cord for conditions such as tumors, stroke, and multiple sclerosis.
- MRI helps assess injuries to muscles, ligaments, and joints, including tears and fractures.
- MRI can evaluate heart structures, function, and blood flow, useful in diagnosing heart diseases.
- MRI provides detailed images of soft tissues.
- MRI can be used for various conditions and body parts.
- MRI allows for the assessment of physiological processes.
Computed Tomography (CT)
- CT scans use X-rays to create detailed 3D images of internal structures.
- CT scans help guide surgeons during procedures such as biopsies or planning surgeries.
- CT scans detect internal bleeding, brain injuries, and other conditions after trauma.
- CT scans help identify the cause of abdominal pain.
- CT scans locate tumors, assess their size, and stage cancers.
- CT scans monitor how cancer responds to treatment.
- CT scans provide detailed 3D images of the body.
- CT scans are a very accurate tool for detecting abnormalities.
Fluoroscopy
- Fluoroscopy uses continuous X-rays to create real-time, moving images of internal structures.
- Fluoroscopy is used to guide a variety of procedures, such as catheter insertion, stent placement, or biopsy.
- Fluoroscopy can visualize blood vessels and conditions like blockages or aneurysms.
- Fluoroscopy assists in fracture repair, spinal surgeries, and joint replacement procedures.
- Fluoroscopy provides quick and efficient results.
- Fluoroscopy can be used in various medical fields, including cardiology, gastroenterology, orthopedics, and urology.
