The ultrasound equipment must be sufficiently high-quality to give a correct image-processing result, which can then provide invaluable information, mainly at the superficial level. It must be able to provide both color and Doppler imaging, technologies that developed alongside the development of ultrasound. Doppler measurements which trace the ...
Ultrasound-guided hip joint injection is a joint injection in the hip, assisted by medical ultrasound. Hip and groin pain often presents a diagnostic and therapeutic challenge. The differential diagnosis is extensive, comprising intra-articular and extra-articular pathology and referred pain from lumbar spine, knee and elsewhere in the pelvis.
A saphena varix, or saphenous varix, is a dilation of the great saphenous vein at its junction with the femoral vein in the groin. It is a common surgical problem, and patients may present with groin swelling.
Diagnosis may involve testing urine samples or an ultrasound. Treatment can include antibiotics, medications to address pain and swelling, or surgical removal of the epididymis. [18] Epididymal cysts is a mass that forms in the epididymis. [10] These cysts differ from spermatoceles as they contain clear fluid, rather than seminal fluid.
The risk of deep vein thrombosis can be estimated by Wells score.. Lower limbs venous ultrasonography is also indicated in cases of suspected pulmonary embolism where a CT pulmonary angiogram is negative but a high clinical suspicion of pulmonary embolism remains. [1]
The catheter is then advanced, also under ultrasound guidance, to the level of the groin or knee crease. Dilute local anesthesia is injected around and along the vein (perivascular infiltration) using ultrasound imaging to place the local anesthetic solution around the vein, mostly in a sub-facial location.
An inguinal hernia or groin hernia is a hernia (protrusion) of abdominal cavity contents through the inguinal canal. Symptoms, which may include pain or discomfort especially with or following coughing, exercise, or bowel movements , are absent in about a third of patients.
Ultrasound is defined by the American National Standards Institute as "sound at frequencies greater than 20 kHz". In air at atmospheric pressure, ultrasonic waves have wavelengths of 1.9 cm or less. Ultrasound can be generated at very high frequencies; ultrasound is used for sonochemistry at frequencies up to multiple hundreds of kilohertz.
