Ultrasonography

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...

Detailed Structure and Function of Lymph Nodes

Detailed Structure and Function of Lymph Nodes

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...

Imaging Studies II: Ultrasonography

IntroductionUltrasonography, or renal ultrasound, is a noninvasive medical imaging technique that uses high-frequency sound waves to visualize the kidneys, ureters, bladder, and surrounding tissues.Indications for Urinary System UltrasonographyUrinary system ultrasonography is indicated in various clinical scenarios, such as:Kidney Stones (Urolithiasis): To detect and monitor the size and presence of kidney or urinary tract stones.Hydronephrosis: To assess the dilation of the renal pelvis and...

Development of the Lymphatic System

Development of the Lymphatic System

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...

Area of Science:

Veterinary Medicine
Diagnostic Imaging
Oncology

Background:

Lymph node evaluation is crucial for cancer staging in small animals.
Ultrasound is a versatile imaging modality for assessing lymph nodes.

Purpose of the Study:

To review the application of ultrasound in detecting, evaluating, and sampling lymph nodes in small animals.
To highlight key ultrasound parameters for lymph node assessment.

Main Methods:

Discussion of ultrasound parameters: size, margins, echogenicity, echopattern, acoustic transmission, vascularity.
Focus on diagnostically significant metrics: short/long axis ratio, vascular distribution patterns, resistive and pulsatility indices.

Main Results:

Ultrasound enables comprehensive evaluation of normal and abnormal lymph nodes.
Specific parameters significantly aid in differentiating benign from malignant lymph nodes.
Ultrasound guides accurate biopsy sampling for definitive diagnosis.

Conclusions:

Ultrasound is an indispensable tool for lymph node assessment in small animal oncology.
Optimizing the use of ultrasound parameters improves diagnostic accuracy and patient management.
This review provides a framework for utilizing ultrasound in small animal lymph node staging.
