Hadlock in ultrasound refers to the Hadlock Formula, a set of equations used to estimate fetal weight (EFW) based on ultrasound measurements of head circumference (HC), abdominal circumference (AC), and femur length (FL). Developed by Dr. Frank Hadlock, it is the most commonly used method for EFW estimation in the second and third trimesters. The […]

A viability ultrasound, also known as a second-trimester ultrasound, is conducted between weeks 18 and 22 of pregnancy. Its primary purpose is to assess fetal viability, growth, and overall well-being. During this exam, trained professionals utilize advanced ultrasound technology to evaluate fetal anatomy, measure key parameters such as gestational age and estimated fetal weight, and

Echogenic intracardiac focus, a bright spot visualized on fetal echocardiography, represents abnormal calcification or fibrosis within the myocardium. It can indicate cardiac abnormalities such as Down syndrome, congenital heart defects, or cardiomyopathy. Early detection and evaluation of echogenic intracardiac foci are crucial for appropriate management and counseling. Unveiling the Spectrum of Cardiac Mass Lesions The

Sonography is a branch of radiology that uses ultrasound technology to create images of internal organs and tissues. It is often used for prenatal exams, to evaluate blood flow, and to assess heart function. Unlike ultrasound, which is a broader term referring to the use of sound waves for medical diagnostics, sonography specifically focuses on

Optical frequency domain imaging (OFDI) is a non-invasive imaging technique that utilizes near-infrared light to capture cross-sectional images of biological tissues. It employs techniques like OCT, OCTA, and SLO to achieve high-resolution and real-time imaging, making it valuable in fields such as ophthalmology and dermatology. OFDI systems comprise a light source, optical probe, and detector,

Ultrasound picture sizes vary depending on the imaging system and settings used. Typically, they range from 3.5 x 4.0 cm (1.4 x 1.6 inches) to 10 x 12 cm (4 x 4.7 inches). Smaller images are suitable for capturing specific anatomical regions, while larger ones provide a wider field of view. The resolution of ultrasound

To obtain an ultrasound, effectively communicate your symptoms and concerns to your healthcare provider. Clearly explain the reason for your request, such as abdominal pain or pregnancy. Discuss any relevant medical history and provide a clear explanation of your symptoms. Remember to ask specific questions and express your concerns openly to ensure a thorough understanding

During an ultrasound, the transducer sends out high-frequency sound waves that bounce off the tissues and organs in the body, creating images. Red and blue colors are used to distinguish between different types of tissue. Red typically represents blood flow, while blue represents surrounding tissue and organs. By analyzing the color patterns, doctors can assess

Ultrasound imaging uses color to represent different blood flow patterns. Red represents blood flowing towards the transducer, blue indicates blood moving away, and green implies a turbulent flow. These colors help diagnose conditions like arterial stenosis (narrowing of arteries) and venous insufficiency (impaired blood flow in veins). Advanced imaging techniques like color Doppler and power

On ultrasound, hair follicles appear as small, oval structures located in the dermis. They are characterized by a high-density center (hair shaft) and a thin, surrounding membrane (epithelial sheath). Hair follicles provide insight into hair growth patterns and can aid in diagnosing hair-related conditions such as alopecia and hirsutism. Hair Follicles: The Foundation of Hair
