Computed Tomography01:10

Computed Tomography

7.8K
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...

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...

Assessment of the Abdomen II: Percussion

1.5K
Percussion is a fundamental technique used to assess the liver, spleen, and abdominal organs by tapping the abdomen and interpreting the resulting sounds. This method helps identify fluid, distention, and masses through variations in sound, such as the high-pitched tympany of air-filled areas and the dullness of solid masses. Understanding how to percuss these organs provides valuable information for healthcare professionals in diagnosing conditions early.

Development of the Lymphatic System01:15

Development of the Lymphatic System

1.8K
The development of lymphatic tissues and vessels in embryonic life begins around the fifth week. These structures originate from the mesoderm layer, with lymph sacs emerging from developing veins.
The first lymph sacs to form are the paired jugular lymph sacs located at the junction of the internal jugular and subclavian veins. From these sacs, lymphatic capillary plexuses extend to the thorax, upper limbs, neck, and head, eventually forming lymphatic vessels. Each jugular lymph sac maintains a...

Detailed Structure and Function of Lymph Nodes01:23

Detailed Structure and Function of Lymph Nodes

3.9K
Lymph nodes are bean-shaped structures that cluster along the lymphatic vessels in the inguinal, axillary, and cervical regions. Each node is divided into compartments by a capsule that extends trabeculae inward.
From a histological perspective, lymph nodes can be split into two main areas: the superficial cortex and the deep medulla. The outer cortex is populated by dendritic cells, macrophages, and B lymphocytes, which are densely packed into follicles. When these B-lymphocytes are presented...

Secondary Lymphoid Organs01:15

Secondary Lymphoid Organs

8.6K
Secondary organs, including lymph nodes, the spleen, and mucosa-associated lymphoid tissue (MALT), work harmoniously to protect us from disease and infection.
The spleen is a vital organ in the lymphatic system, nestled in the upper left side of the abdomen. It is composed of two primary regions: the red pulp and the white pulp, each having distinct functions. The red pulp performs a significant role in blood filtration. It efficiently purges the blood of old or damaged red blood cells and...

Summary

Pediatric abdominal lymph node sizes were evaluated using CT scans. Adult criteria for enlarged lymph nodes are generally applicable to children, but larger nodes are common in young adolescents, especially in the inguinal region.

Area of Science:

  • Pediatric Radiology
  • Medical Imaging
  • Anatomy

Background:

  • Lymph node enlargement is a common indicator of abnormality.
  • Establishing normal lymph node size in children is crucial for accurate diagnosis.

Purpose of the Study:

  • To determine the normal size and prevalence of abdominal lymph nodes in children using computed tomography (CT).
  • To establish reference intervals for abdominal lymph node dimensions in pediatric patients.

Main Methods:

  • Retrospective analysis of 152 children (ages 1-17) who underwent abdominal CT after trauma.
  • Measurement of lymph nodes in five stations (inguinal, iliac, para-aortic, hepatic, mesenteric).
  • Correlation of lymph node size with age and application of adult criteria (Lugano, RECIST).

Main Results:

  • High prevalence of detectable lymph nodes in inguinal, iliac, para-aortic, and mesenteric regions.
  • Significant, small to medium correlations between lymph node size and age.
  • 19% of children met enlarged lymph node criteria based on adult guidelines.

Conclusions:

  • Provides normative data for pediatric abdominal lymph node size.
  • Adult guidelines are mostly suitable, but larger inguinal lymph nodes are common in young adolescents.
