Ultrasonography01:17

Ultrasonography

Ultrasonography is an imaging technique that uses high-frequency sound waves to visualize the body's internal structures. It is a non-invasive and safe procedure that does not involve the use of ionizing radiation, making it widely used in various medical fields. Ultrasonography is used to study heart function, blood flow in the neck or extremities, certain conditions such as gallbladder disease, and fetal growth and development.
During an ultrasonography procedure, a handheld device called a...
X-ray Imaging01:24

X-ray Imaging

German physicist Wilhelm Röntgen (1845–1923) was experimenting with electrical current when he discovered that a mysterious and invisible "ray" would pass through his flesh but leave an outline of his bones on a screen coated with a metal compound. In 1895, Röntgen made the first durable record of the internal parts of a living human: an "X-ray" image (as it came to be called) of his wife’s hand. Scientists worldwide quickly began their own experiments with X-rays, and by 1900, X-ray was widely...
Blood and Nerve Supply to the Bones01:29

Blood and Nerve Supply to the Bones

Bones are dynamic organs that require a rich supply of oxygen and nutrients. Around 5% to 10% of the cardiac output supplies blood to the bones. A typical long bone has three main sources: the nutrient artery, the metaphyseal and epiphyseal arteries, and the periosteal arteries.
Nutrient Artery
The nutrient artery is the main blood vessel that enters the diaphysis via the nutrient foramen. While most long bones have only one nutrient foramen, large bones, such as the femur, may have two. This...

Imaging Studies I: CT and MRI

Introduction: MRI and CT scans are crucial advancements in medical imaging techniques, playing a vital role in diagnosing conditions related to the gastrointestinal (GI) system. Each scan serves distinct purposes, targets specific areas, and requires unique nursing duties.
Description of the Procedures
Computed Tomography (CT) scan:
Computed Tomography (CT) scans use X-ray technology to generate detailed images of bones, organs, and tissues. During the scan, the patient lies on a moving table...

Area of Science:

  • Orthopedics
  • Radiology
  • Pathology

Background:

  • Aseptic bone necroses encompass diverse conditions lacking infectious etiology.
  • These include osteochondroses and necroses linked to physical factors, drugs, or systemic disorders.
  • While occurring in any bone, certain locations and age groups are more commonly affected.

Purpose of the Study:

  • To review the diagnostic approaches for aseptic bone necroses.
  • To highlight the role of imaging in early detection and classification.
  • To emphasize the importance of radiologist-clinician collaboration.

Main Methods:

  • Review of typical locations, age, risk factors, and clinical data for diagnosis.
  • Evaluation of plain film radiography for characteristic changes.
  • Assessment of Magnetic Resonance Imaging (MRI) for early and definitive diagnosis.

Main Results:

  • Plain film interpretation combined with clinical data aids diagnosis.
  • MRI is crucial for detecting early-stage disease and subtle findings.
  • MRI-based classifications facilitate therapeutic planning.

Conclusions:

  • Accurate diagnosis relies on understanding typical presentations and risk factors.
  • Advanced imaging, particularly MRI, is essential for early and conclusive diagnosis.
  • Effective management necessitates close cooperation between radiologists and clinicians.
