GIS Software, Hardware, and Sources of GIS Data01:23

GIS Software, Hardware, and Sources of GIS Data

777
A Geographic Information System (GIS) combines specialized software and hardware to effectively manage, analyze, and present spatial and related data. GIS software includes critical functionalities such as a user interface for easy navigation, database management tools for handling spatial and attribute data, and data retrieval features for efficient access. Analytical tools transform raw data into insights, while display functions produce maps and reports in various formats for effective...

Fixation and Sectioning01:03

Fixation and Sectioning

7.5K
Two basic types of preparation are used to visualize specimens with a light microscope: wet mounts and fixed specimens.
The simplest type of preparation is the wet mount, in which the specimen is placed in a drop of liquid on the slide. A liquid specimen can be directly deposited on the slide using a dropper. Solid specimens, such as skin scraping, can be placed on the slide before adding a drop of liquid to prepare the wet mount. Sometimes the liquid is simply water, but stains are often added...

Carbon-dioxide Fixation01:28

Carbon-dioxide Fixation

688
Carbon dioxide fixation in prokaryotes enables the assimilation of inorganic carbon into organic molecules, supporting biosynthetic pathways, sustaining ecosystems, and contributing to the global carbon cycle. It also has industrial applications in carbon capture and bioproduct synthesis. Autotrophic organisms rely on this process to utilize CO₂ as a carbon source in diverse environments.The Calvin CycleThe Calvin cycle is the most widespread carbon fixation mechanism, primarily used by...

Spinal Cord01:26

Spinal Cord

1.7K
The spinal cord, a critical component of the central nervous system, extends from the base of the brainstem to the lumbar region of the vertebral column. It is essential for maintaining physical stability and facilitating communication between the brain and peripheral parts of the body.

The Spinal Cord01:54

The Spinal Cord

31.6K
The spinal cord is the body’s major nerve tract of the central nervous system, communicating afferent sensory information from the periphery to the brain and efferent motor information from the brain to the body. The human spinal cord extends from the hole at the base of the skull, or foramen magnum, to the level of the first or second lumbar vertebra.

Spinal Cord: Information Processing01:10

Spinal Cord: Information Processing

3.3K
The spinal cord is an integral hub for motor and sensory information that enables the brain to communicate with the peripheral nervous system (PNS). This communication consists of relaying sensory data and transmission of motor commands.
Sensory Information Processing
Sensory information processing begins at the sensory receptors located in the skin and other tissues, which detect somatic sensory stimuli such as touch, temperature, or pain. These receptors function as catalysts, initiating...

Area of Science:

  • Orthopedics
  • Radiology
  • Neurosurgery

Background:

  • Instrumented spinal surgeries utilize fixation hardware for stabilization.
  • Postoperative assessment of this hardware is crucial for patient outcomes.
  • Potential complications can arise from spinal instrumentation.

Purpose of the Study:

  • To discuss the radiologic assessment of spinal fixation hardware.
  • To highlight the role of imaging in detecting postsurgical complications.
  • To emphasize the importance of recognizing normal imaging findings for clinical management.

Main Methods:

  • Review of standard postoperative assessment using radiography.
  • Utilizing computed tomography (CT) and magnetic resonance imaging (MRI) for detailed evaluation.
  • Familiarity with normal imaging appearance of implanted hardware and osseous arthrodesis progression.

Main Results:

  • Radiography is the standard for initial postoperative assessment.
  • CT and MRI are valuable for detecting hardware complications like infection, pseudarthrosis, and malposition.
  • Normal imaging progression aids in identifying deviations and potential issues.

Conclusions:

  • Radiologic assessment is vital for evaluating spinal hardware post-surgery.
  • Advanced imaging techniques (CT, MRI) are essential for diagnosing complications.
  • Knowledge of normal imaging findings facilitates timely and effective clinical management of spinal hardware patients.
