8. Specialties in Radiologic Technology Flashcards
(47 cards)
Ultrasound-based diagnostic imaging technique used for visualizing subcutaneous body structures including tendons, muscles, joints, vessels and organs for pathology or lesions.
Sonography
Ultrasound
Sonography
Diagnostic ultrasound range
2 to 18 MHz
Produce less resolution but penetrate deeper
Low frequency (1-6 MHz)
Produce high resolution but lower penetration
High frequency (7-18 MHz)
Diagnostic medical professionals who operate ultrasonic imaging devices to produce diagnostic images, scans, videos, or 3D volumes of anatomy and diagnostic data
Sonographers
Provides a live-action view of the interior body
Fluoroscopy
Device that electronically brightens and enhances the image and transmits it to the monitor
Image-intensifier
Enhances images of the body and has the ability of post-processing
Digital Imaging
Two types of Digital Imaging
- Computed Radiography
- Direct Digital Radiography
Produces 2-D and 3-D cross-sectional images of an object from flat x-ray images
Computed Tomography
- Operate CT-Scan machine
- Explain procedure to the patient
- Immobilize and observe the patient during procedure
- Monitor video display of area being scanned and improve image quality
- Review and evaluate CT-Scan images
- Use radiation safety measures and protection devices
CT-Scan Technologist
Is a medical imaging technique used in radiology to visualize detailed internal structures using nuclear
magnetic resonance property
Magnetic Resonance Imaging
-MRI, NMRI, or MRT
Uses a powerful magnetic field to align the magnetization of some atoms in the body, and radiofrequency fields to systematically alter the alignment of magnetization.
MRI machine
- Performs the prescribed examination
- Explain the procedure and positions the patient
- Should answer any questions from the patient
- Monitor the safety of the patient and be prepared to perform emergency procedures
- Assist the patient
- Prepare the equipment and proper settings for image acquisition
- Must follow hospital procedures for recording images with the patient’s record for doctors to evaluate
MRI Technologist
Provides information about both structure and function and treat disease with the use of radiopharmaceuticals.
Nuclear Medicine
- Prepare and administer radiopharmaceuticals
- Perform imaging procedures using radiation-detecting instruments
- Accomplish computer processing and image enhancement
- Analyze biologic specimens in the laboratory
- Provide images, data analysis, and patient information to the physician for diagnostic interpretation
- Obtain patient history, describe the procedure to the patient and answer any questions
- Monitors the patient’s physical condition during the procedure
Nuclear Medicine Technologist
Uses a radiopharmaceutical agent injected in the circulatory system to image the area of interest for the evaluation of anatomic and physiologic condition of an organ.
Positron Emission Tomography (PET)
Is a nuclear medicine tomographic imaging technique using gamma rays.
Single-photon emission computed tomography (SPECT)
It is very similar to conventional nuclear medicine planar imaging using a gamma camera. However, it
is able to provide true 3D information.
Single-photon emission computed tomography (SPECT)
This information is typically presented as cross-sectional slices through the patient, but can be freely reformatted or manipulated as required.
Single-photon emission computed tomography (SPECT)
Is a test like an X-ray that quickly and accurately measures the density of bone.
Bone Densitometry
It is used primarily to detect osteopenia or osteoporosis, diseases in which the bone’s mineral and density are low and the risk of fractures is increased.
Bone Densitometry
Medical use of ionizing radiation, generally as part of cancer treatment to control or kill malignant cells.
Radiation Therapy
