Computed Tomography01:10

Computed Tomography

Tomography refers to imaging by sections. Computed tomography (CT) is a non-invasive imaging technique that uses computers to analyze several cross-sectional X-rays to reveal minute details about structures in the body.
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...
The Effect of Aging on Tissues01:19

The Effect of Aging on Tissues

Several body functions deteriorate with age. The external signs of aging are easily identifiable. For example, the skin becomes dry, less elastic, and thins out, forming wrinkles. The skin of the face begins to appear looser due to a decrease in the levels of elastic and collagen fibers in the connective tissue. Additionally, melanin production in the hair follicle decreases with age, resulting in gray hair. Moreover, the senses of sight and hearing decline, so glasses and hearing aids may...

Imaging Studies for Cardiovascular System V: CT

Cardiac computed tomography (CT) scanning is an advanced cardiac imaging technique that utilizes CT technology, with or without intravenous (IV) contrast, to produce accurate cross-sectional virtual slices of specific areas of the heart, coronary circulation, and major blood vessels such as the aorta, pulmonary veins, and arteries. The computer processes these slices to generate three-dimensional images. Multidetector CT (MDCT) is a rapid form of CT scanning that captures multiple slices...

Imaging Studies for Cardiovascular System VI: Calcium -Scoring CT

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...

Imaging Studies III: Computed Tomography

DefinitionComputed Tomography (CT) of the genitourinary (GU) tract is a non-invasive imaging modality that utilizes X-rays and computer processing to generate detailed cross-sectional images of the urinary system, encompassing the kidneys, ureters, bladder, and adjacent structures such as the adrenal glands.PurposeCT scans of the GU tract serve several diagnostic and therapeutic purposes, including:Diagnosis of Urinary Tract Diseases: Detects kidney stones, tumors, cysts, and congenital...

Summary

Elderly men exhibit reduced thigh muscle mass and increased non-muscle tissue compared to younger men. These anatomical differences, revealed by computed tomography (CT) scans, necessitate careful consideration when comparing leg strength.

Area of Science:

  • Gerontology
  • Anatomy
  • Biomedical Engineering

Background:

  • Age-related changes in body composition are significant.
  • Understanding thigh component alterations is crucial for assessing functional decline.

Purpose of the Study:

  • To quantitatively compare thigh muscle and non-muscle tissue components between young and elderly men using computed tomography (CT).
  • To investigate the impact of aging on lean muscle area and non-muscle tissue within thigh compartments.

Main Methods:

  • Computed tomography (CT) scans were employed to measure cross-sectional areas (CSA) of thigh components in young and elderly men.
  • Quantification included total limb, muscle plus bone, quadriceps, hamstring, bone, skin plus subcutaneous fat, and non-muscle tissue (NMT).
  • Geometric formulae and regression equations were used to calculate volumes and predict component volumes.

Main Results:

  • Elderly men showed significantly smaller total muscle plus bone CSA (13.0%), quadriceps CSA (26.4%), and hamstring CSA (17.9%).
  • Elderly men had significantly greater skin plus subcutaneous fat CSA (37.6%) and NMT within muscle compartments (quadriceps 59.4%, hamstring 127.3%).
  • Total thigh CSA did not differ significantly between age groups.

Conclusions:

  • Aging leads to a substantial decrease in lean muscle mass and an increase in non-muscle tissue within the thigh.
  • Direct comparisons of leg muscle strength between young and elderly individuals may be misleading without accounting for these compositional changes.
  • Accurate quantification of muscle size and CSA is essential for meaningful strength comparisons in aging populations.
