The portal vein should be hepatopedal and nonpulsatile.
The hepatic veins should be hepatopedal and pulsatile.
The hepatic artery should be pulsatile with a high resistance waveform.
The splenic vein has a waveform most similar to normal hepatic veins.
Ascites is rare.
It is secondary to acute portal vein thrombosis.
The caudate lobe can be spared.
Intrahepatic collaterals most commonly extend from the hepatic veins to the portal venous system.
Regardless of their size cavernous hemangiomas appear as a uniformly echogenic homogeneous hepatic mass.
All patients with suspected hepatic hemangioma based on characteristic ultrasound appearance should have a confirmatory CT or MRI scan.
There is an association between thrombocytopenia and cavernous hemangioma.
A well-recognized sonographic appearance of hemangioma is that of an echogenic center surrounded by a hypoechoic rim.
Corpus luteum cyst
Ovarian tumor of low malignant potential
Ovarian cystic teratoma
It refers to obstruction of the common hepatic duct by an impacted cystic duct stone.
It is a clinical syndrome of painless jaundice in an elderly patient.
Ultrasound of the liver shows pneumobilia.
It is associated with primary sclerosing cholangitis.
Ill-defined hyperechoic nodule
Nodule with honeycomb pattern of cystic change and thin hypoechoic rim
Hypoechoic nodule with microcalcifications
Oval nodule with peripheral eggshell calcification
Renal artery stenosis is the underlying cause of hypertension in almost 50% of adult women.
Measurement of the peak systolic velocity in the main renal artery is considered the most accurate parameter for the sonographic diagnosis of hemodynamically significant renal artery stenosis.
A parvus tardus appearance of the arterial waveform in the intrarenal arterial branches of the kidney is an indication of ipsilateral renal vein thrombosis.
For accurate measurements of the peak systolic velocity in the main renal arteries the Doppler angle should be kept above 60 degrees.
