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
Authors: Henry Suarez RDMS, RVT; Richard Garay R.T. (S), RDMS, RVT Hemodialysis Hemodialysis is a medical procedure that uses a dialysis machine to filter wastes and water from your blood in cases of renal failure. In order to use a hemodialysis machine the patient needs access to their blood supply. This is achieved with a hemodialysis… Read More Hemodialysis Vascular Access
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
Continuing with the series, here’s the videos for RVT. Stay tuned for other specialties coming in the following weeks!
Welcome to a primer on Upper and Lower Extremity duplex sonography.… Read More Arterial Sonography of the Upper and Lower Extremities
Transcranial Doppler is used to identify and interrogate the intracerebral arterial system. Normally the skull is impenetrable to Ultrasound waves, but using certain windows allows adequate penetration to monitor cerebrovascular hemodynamics.… Read More Transcranial Doppler
The brain is fed oxygenated blood by paired vessels that arises from the aortic arch.… Read More Carotid Duplex
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
The renal veins are paired blood vessels that return blood back to the IVC. The left renal vein is the longer one and courses between the superior mesenteric artery and aorta. It is important to visualize these vessels to rule out Renal Vein Thrombosis, or Nutcracker syndrome.… Read More Renal Artery Doppler
