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...

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...

Classification of Connective Tissues

Classification of Connective Tissues

The connective tissues have different properties and functions in the human body. They are broadly categorized into proper, supporting, or fluid connective tissues.
Connective Tissue Proper
Connective tissue proper is the most abundant class of connective tissues. As its name implies, it predominantly connects different tissues in the body. Depending on the cell types, ground substance, viscosity, and fiber types in the ECM, connective tissue proper is further categorized into loose and dense.

Classification of Epithelial Tissues: Overview

Classification of Epithelial Tissues: Overview

Epithelial tissues are classified according to the shape of the cells and the number of cell layers formed. Cell shapes can be squamous (flattened and thin), cuboidal (square-like, as wide as it is tall), or columnar (rectangular, taller than it is wide). Additionally, the nucleus shape helps identify the type of epithelial cells. Squamous cells have flattened disc-shaped nuclei, cuboidal cells have spherical nuclei, and columnar cells have elongated nuclei.
Based on the number of cell layers,...

Ultrasound I: Abdominal Ultrasonography

Ultrasound I: Abdominal Ultrasonography

Introduction:
Abdominal ultrasonography, commonly known as abdominal ultrasound, is a vital, non-invasive medical imaging technique widely used in healthcare.
Procedure:
This diagnostic tool allows the clinician to visually inspect internal structures within the abdomen, including vital organs such as the liver, gallbladder, pancreas, kidneys, and spleen.
The abdominal ultrasound process begins with applying a special gel to the patient's skin over the abdomen. This gel enhances the...

Summary

Ultrasonography can differentiate benign and malignant soft tissue tumors. This imaging technique accurately identifies soft tissue sarcomas and aggressive benign lesions, guiding appropriate patient management.

Area of Science:

Radiology
Oncology
Pathology

Background:

Malignant soft tissue tumors are rare compared to benign lesions.
Misdiagnosis of soft tissue sarcoma can delay or alter treatment.
Accurate differentiation is crucial for effective patient management.

Purpose of the Study:

To evaluate ultrasonography's ability to distinguish between benign and malignant soft tissue tumors.
To assess the diagnostic performance of B-mode and color Doppler sonography in soft tissue lesions.

Main Methods:

A prospective study of 224 histologically confirmed soft tissue tumors over 8 years.
Inclusion of 120 sarcomas and 27 aggressive benign lesions.
Computer-based analysis of echotexture (echogenicity, homogeneity, vascularization) using B-mode and color Doppler sonography.

Main Results:

A 6-category classification based on echotexture patterns (echogenicity, homogeneity, vascularization) was developed.
The classification achieved 94.4% sensitivity and 79.7% specificity for detecting soft tissue sarcomas and aggressive benign lesions.
Overall accuracy for differentiating tumor types was 89.7%.

Conclusions:

Ultrasonography aids in determining diagnostic and therapeutic pathways for soft tissue tumors.
Hypervascularized, homogenous hypoechoic/hyperechoic soft tissue sarcomas and predominantly homogenous hypoechoic aggressive benign tumors necessitate biopsy.
Homogenous hyperechoic lesions with low vascularization may allow for conservative management; biopsy is recommended for heavily inhomogeneous tumors to rule out sarcoma.
