Insights

This study introduces a new device to measure internal organ density, finding it correlates with pathologic changes like edema and fatty degeneration in autopsy samples. Organ density may help detect these common tissue abnormalities.

Area of Science:

  • Pathology
  • Medical Devices
  • Biophysics

Background:

  • Pathologic changes in internal organs, such as edema and fatty degeneration, can alter tissue properties.
  • Accurate and non-invasive methods for assessing these changes are crucial for diagnosis and prognosis.

Purpose of the Study:

  • To design and validate a novel device for measuring internal organ density.
  • To investigate the correlation between measured organ density and histologically confirmed pathologic changes in autopsy specimens.

Main Methods:

  • An integrated volume-density meter was used to measure the density of hearts, livers, lungs, and brains from 169 autopsy cases.
  • Organ samples were categorized into intact and pathologic groups, with pathologic changes classified into three stages (slight, intermediate, severe edema/fatty degeneration).

Main Results:

  • Significant differences in density were observed between intact and all subgroups of pathologic organs.
  • A close correlation was established between organ density measurements and the extent of pathologic changes, including edema and fatty degeneration.

Conclusions:

  • Measured organ density serves as a valuable external parameter for identifying and quantifying internal organ pathologies.
  • The developed device and methodology show potential for aiding in the assessment of tissue abnormalities like edema and fatty changes.

Assessment of the Abdomen III: Palpation

Palpation is a crucial tactile examination method for assessing abdominal organs and detecting conditions like tenderness, distention, masses, or fluid. It involves both light and deep palpation techniques, each serving specific diagnostic purposes. Light palpation helps identify tenderness and other surface-level indicators, while deep palpation locates and assess abdominal masses and organ boundaries. A skilled professional can gather valuable insights through palpation, including evaluating...
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...
Density00:56

Density

Density is an important characteristic of substances, crucial in determining whether an object sinks or floats in a fluid. Its SI unit is kg/m3, and its cgs unit is g/cm3. The density of an object helps in identifying its composition, and also reveals information about the phase of the matter and its substructure. The densities of liquids and solids are roughly comparable, consistent with the fact that their atoms are in close contact. However, gases have much lower densities than liquids and...
Gross Anatomy of the Liver01:17

Gross Anatomy of the Liver

The liver, the largest gland within the human body, is a firm and reddish-brown organ. This wedge-shaped structure weighs approximately 1.5 kg and occupies a significant portion of the right hypochondriac and epigastric regions. It extends more to the right of the body's midline than to the left.
Located under the diaphragm, the liver is almost entirely ensconced within the rib cage, providing it with substantial protection. Except for the superior most bare area, the liver's surface is covered...
Veins as Blood Reservoirs01:10

Veins as Blood Reservoirs

Veins, while chiefly responsible for circulating blood back to the heart, also function as storage vessels for blood. They house approximately 64 percent of the body's total blood volume, a feat made possible by their high capacitance—the inherent ability to expand and accommodate large volumes of blood, even under low pressure. The large diameter and thin walls of veins augment their distensibility, significantly more so than arteries, due to their classification as capacitance vessels. When...
