Summary
Real-time B-mode sonography, a noninvasive diagnostic tool, is valuable in dermatology for assessing skin tumors and inflammatory conditions. Advanced ultrasound techniques offer detailed tumor characteristics and aid in patient monitoring during treatment.
Area of Science:
- Medical Imaging
- Dermatology
- Diagnostic Ultrasound
Background:
- Real-time B-mode sonography is a standard noninvasive diagnostic method across various medical fields.
- Ultrasound technology has been increasingly adopted in clinical dermatology over the past three decades.
- High-frequency ultrasound (20-50 MHz) is established for skin tumor and inflammation assessment, aiding preoperative planning and therapy monitoring.
Purpose of the Study:
- To review the established and emerging applications of ultrasound technology in clinical dermatology.
- To highlight the utility of both high-frequency and lower-frequency ultrasound probes in dermatological diagnostics.
- To discuss advanced ultrasound techniques and their role in evaluating skin conditions.
Main Methods:
- Review of real-time B-mode sonography applications in dermatology.
- Discussion of high-frequency (20-50 MHz) and lower-frequency (7.5-15 MHz) ultrasound systems.
- Inclusion of newer techniques: color Doppler sonography and ultrasound-guided fine needle aspiration cytology.
Main Results:
- High-frequency ultrasound provides detailed assessment of skin tumors and inflammatory processes, including size, extension, and relation to surrounding structures.
- Lower-frequency ultrasound (7.5-15 MHz), though less widely accepted, shows promise for evaluating peripheral lymph nodes and soft-tissue tumors.
- Ultrasound offers valuable information on tumor characteristics (solid, cyst, complex) and internal structure (echogenicity, homogeneity, calcifications, necroses), aiding in patient follow-up during chemotherapy or radiotherapy.
Conclusions:
- Ultrasound, particularly high-frequency systems, is a powerful noninvasive tool for dermatological diagnosis and monitoring.
- While not providing malignancy-specific information, ultrasound is crucial for characterizing lesions and guiding treatment.
- Advanced ultrasound techniques enhance diagnostic capabilities in dermatology, complementing conventional methods.

01:17Ultrasonography
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.

01:20Ultrasound 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...

01:19Assessing Blood pressure using a doppler ultrasound
To obtain accurate blood pressure measurements in clinical settings, especially when traditional methods are insufficient, healthcare professionals utilize the Doppler ultrasound technique. This method uses high-frequency sound waves to detect blood flow within the arteries, which is crucial for patients with conditions that complicate circulatory system assessment.
