Authors: Henry Suarez RDMS, RVT; Richard Garay R.T. (S), RDMS, RVT Reflux Today we have a case to evaluate for the presence of “ venous reflux”.“Venous reflux” is a common abnormality due to valvular incompetence leading to the conditionknown as venous insufficiency. Venous insufficiency is caused by the backwards flow of blood in the veins… Read More Venous Insufficiency Case/Protocol
Transducer I use a 6 MHz (dropping the frequency between 4-5 if necessary) Curvilinear abdominal transducer and the 9 MHz linear transducer to get higher res doppler, gray scale and bflow images. If the patient is obese you may use a sector transducer. I like to begin the exam examining the native kidneys. Now a… Read More Renal Transplant Duplex Protocol
Protocol image sequence (Right side only repeat images on left testis for complete protocol). Transverse Begin in transverse what’s know colloquially as the “twins” view. This view is great for determining quickly symmetry, position and echotexture. With color doppler you can determine whether there is testicular torsion. In cases of undescended testis you can show… Read More Testicular/Scrotal Doppler Protocol
Here is the protocol for the complete renal ultrasound. BLADDER Sagittal With a full bladder begin at midline and take right and left lateral images in sagittal. Measure the bladder wall per protocols or indication. A normal adult bladder can hold about 470 ml of urine or about 2 cups. TRANSVERSE Turning your transducer counter… Read More Renal Ultrasound Complete Protocol
Proximal Aorta The aorta is the largest artery that carries oxygenated blood from the heart to the viscera and extremities. Here I share with you the protocol for scanning aortic duplex ultrasounds. Start in the epigastric region at the proximal abdominal aorta and take sagittal grayscale, color Doppler and spectral Doppler and measure the diameter… Read More Aorta Duplex/Doppler Protocol
Here is a quick video explaining the protocol. Liver Protocol basics. The liver is the largest internal organ, the right lobe is 5-6 times larger than the left. Normally measures about 15 cm at mid clavicular line in adults, there is much variation in pediatric populations by age and size.… Read More Liver Anatomy and Protocol
Veins are blood vessels that carry deoxygenated blood toward the heart (with the exception of the pulmonary and portal veins which carry oxygen rich blood to the left atrium and liver respectively). … Read More Lower Extremity Venous Duplex Protocol
