El ultrasonido. Un nuevo enfoque de diagnóstico para el paciente con ictericia
JAMA
|July 18, 1977
Resumen
La ecografía diferencia eficazmente la ictericia quirúrgica de la ictericia médica cuando los datos clínicos no están claros. Esta técnica de imagen identifica con precisión la obstrucción extrahepática y la colestasis intrahepática en pacientes con ictericia.
Área de la Ciencia:
- Imágenes médicas de imágenes médicas.
- Hepatología Hepatología.
- Medicina de diagnóstico La medicina de diagnóstico es la medicina de diagnóstico.
Sus antecedentes:
- Diagnosticar la causa de la ictericia puede ser un desafío.
- La historia clínica, los exámenes físicos y las pruebas de laboratorio a menudo no son concluyentes.
- Diferenciar la obstrucción extrahepática (ictericia quirúrgica) de la colestasis intrahepática (ictericia médica) requiere métodos confiables.
Objetivo del estudio:
- Evaluar la precisión diagnóstica del ultrasonido para diferenciar las causas de la ictericia.
- Para evaluar la utilidad del ultrasonido en los casos en que los métodos convencionales no son concluyentes.
Principales métodos:
- Evaluación prospectiva de 40 pacientes con ictericia durante 14 meses.
- Utilizó el ultrasonido como la principal herramienta de diagnóstico.
- Los resultados se compararon con los hallazgos patológicos.
Principales resultados:
- La ecografía diagnosticó correctamente la obstrucción extrahepática en 23 de los 24 pacientes.
- La ecografía diagnosticó correctamente la colestasis intrahepática en 15 de los 16 pacientes.
- Se observó una baja tasa de errores de diagnóstico (un falso positivo, un falso negativo).
Conclusiones:
- El ultrasonido es una modalidad de imagen altamente precisa para diferenciar la ictericia quirúrgica de la ictericia médica.
- Proporciona información de diagnóstico valiosa cuando los datos clínicos y de laboratorio son equívocos.
- El ultrasonido puede ayudar significativamente en el manejo de pacientes con ictericia.

Assessing 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.

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.

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...

Imaging Studies for Cardiovascular System II:Types of Echocardiography
Echocardiography plays a role in assessing cardiac health and detecting heart conditions, with various types providing critical insights for diagnosis and treatment.
Types of Echocardiography
Transthoracic Echocardiography (TTE)
TTE is the most common type of echocardiogram which involves placing a transducer on the patient's chest, emitting sound waves to create heart images. TTE is invaluable for evaluating the heart's size, structure, and motion, making it particularly useful for diagnosing...
