Imaging Studies for Cardiovascular System III: X-Ray01:20

Imaging Studies for Cardiovascular System III: X-Ray

695
The most common cardiovascular diagnostic test is an X-ray. It produces images of the heart, blood vessels, and adjacent structures.
Definition and Purpose
An X-ray, or radiograph, is a non-invasive method that uses ionizing radiation to take images of internal structures. It is mainly used in cardiac imaging to examine the heart, lungs, and major blood vessels, aiming to identify abnormalities in the heart's size, shape, and position, such as heart failure, congenital defects, and vascular...

X-ray Imaging

7.7K
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...

Imaging Studies for Cardiovascular System VI: Calcium -Scoring CT

971
Calcium-Scoring CT ScanA calcium-scoring CT scan, also known as coronary artery calcium (CAC) scan, detects calcium deposits in the coronary arteries. This test assesses the risk of coronary artery disease (CAD), which can lead to cardiovascular events such as angina, heart failure, and sudden cardiac arrest.A calcium-scoring CT scan is generally recommended for individuals at intermediate risk of CAD without symptoms. It includes:Men aged 40-75 and women aged 50-75: Especially those with a...

Bones of the Upper Limb: Radius01:09

Bones of the Upper Limb: Radius

9.0K
The radius is longer of the two bones that make up the human antebrachium or forearm. At the proximal end, the radius articulates with the capitulum of the humerus and the radial notch of the ulna to form the elbow joint. At the distal end, the radius articulates with the ulna via the ulnar notch, forming the distal radioulnar joint. Distally, the radius also attaches to the carpal wrist bones (scaphoid and lunate) to form the radiocarpal joint.
The radius has a nail-shaped head, and a...

Peripheral Arterial Disease II: Clinical Manifestations and Diagnostic Evaluation

762
Clinical manifestationsPeripheral Arterial Disease (PAD) manifests through a range of symptoms, from the characteristic intermittent claudication to atypical presentations and severe complications in advanced stages. Intermittent claudication, a hallmark symptom of PAD, presents as exercise-induced muscle pain that typically resolves within minutes of rest. This pain is reproducible and stems from inadequate blood flow, leading to the accumulation of lactic acid produced during anaerobic...

Ultrasonography01:17

Ultrasonography

6.5K
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...

Summary

Pseudoerosions on wrist radiographs are common and often mistaken for true erosions in rheumatoid arthritis. Understanding their typical locations, such as ligament insertions, is crucial for accurate diagnosis.

Area of Science:

  • Radiology
  • Orthopedic Imaging
  • Rheumatology

Background:

  • Rheumatoid arthritis (RA) diagnosis relies on detecting bone erosions.
  • Plain radiography is a primary imaging modality for RA.
  • Distinguishing true erosions from pseudoerosions is critical for accurate RA assessment.

Purpose of the Study:

  • To meticulously analyze pseudoerosions of the wrist and hand on plain radiographs.
  • To correlate radiographic findings with anatomical structures.
  • To improve the diagnostic accuracy of plain radiography in RA.

Main Methods:

  • Utilized 28 cadaver wrists for imaging.
  • Compared plain radiography, tomosynthesis, and computed tomography.
  • Radiologists scored 20 specific sites for cortical bone abnormalities.
  • Performed anatomical correlation studies on serial sections.

Main Results:

  • Pseudoerosions were identified in 7.3% of images on plain radiographs.
  • Common sites included specific portions of the capitate, hamate, and metacarpals.
  • Computed tomography confirmed these were not true erosions.
  • Anatomical correlation suggested ligament insertions and cortical bone variations as causes.

Conclusions:

  • Pseudoerosions are frequently observed on wrist radiographs.
  • Knowledge of common pseudoerosion locations is essential for RA diagnosis.
  • Accurate interpretation of plain radiographs requires understanding these anatomical variants.
