Detection of Hepatic Metastases Using Duplex/Color Doppler Sonography

Transcranial Doppler sonography in fulminant hepatic failure.

UNLABELLED The clinical course of patients with fulminant hepatic failure (FHF) is often worsened by the presence of cerebral edema and endocranial hypertension. In spite of the multiple studies using Transcranial Doppler Sonography (TCDS), few have shown the cerebral blood flow (CBF) pattern among patients with encephalopathy resulting from FHF. OBJECTIVE Our objective was to characterize th...

Microembolus Detection by Transcranial Doppler Sonography: Review of the Literature

Transcranial Doppler can detect microembolic signals which are characterized by unidirectional high intensity increase, short duration, random occurrence, and a "whistling" sound. Microembolic signals have been detected in a number of clinical settings: carotid artery stenosis, aortic arch plaques, atrial fibrillation, myocardial infarction, prosthetic heart valves, patent foramen ovale, valvul...

Color Doppler sonography in the detection of parathyroid adenomas.

BACKGROUND Various diagnostic modalities have been utilized to aid in the detection of abnormal parathyroid tissue; however, its localization is not always easy. The purpose of this study was to determine whether the evaluation of potential hemodynamic changes in thyroid arteries could aid in the detection of parathyroid adenomas. METHODS Twenty-eight patients with laboratory evidence of hype...

Doppler Sonography in the Detection of Significant Renal Artery Stenosis

Background Systemic hypertension is a major risk factor both for stroke and for myocardial infarction. The search for underlying treatable cause is a part of the management of a hypertensive patient. Renal vascular hypertension is the most common form of potentially curable hypertension and if untreated may terminate in renal failure. It has been estimated that 10% to 20% of new patients presen...
