CT Perfusion in Acute Stroke: Added Value or Waste of Time?

CT perfusion in acute stroke: added value or waste of time?

CT Perfusion in Acute Stroke: Added Value or Waste of Time? To the Editor: We read with interest the 2 recent articles by Zhu et al regarding the usefulness of computed tomography perfusion (CTP) studies for predicting outcomes in acute stroke patients. We are puzzled by the analysis of data from the same group of patients being interpreted in such diametrically opposite ways by the same author...

Dynamic CT perfusion imaging of acute stroke.

BACKGROUND AND PURPOSE Because cerebral perfusion imaging for acute stroke is unavailable in most hospitals, we investigated the feasibility of a method of perfusion scanning that can be performed rapidly during standard cranial CT. Our aim was to identify the scanning parameters best suited to indicate tissue at risk and to measure a perfusion limit to predict infarction. METHODS Seventy pat...

CT Perfusion in the Characterisation of Renal Lesions: An Added Value to Multiphasic CT

OBJECTIVE To prospectively evaluate if computed tomography perfusion (CTp) could be a useful tool in addition to multiphasic CT in renal lesion characterisation. MATERIALS AND METHODS Fifty-eight patients that were scheduled for surgical resection of a renal mass with a suspicion of renal cell carcinoma (RCC) were enrolled. Forty-one out of 58 patients underwent total or partial nephrectomy a...

Value of perfusion CT-guided recanalization therapy in acute ischemic stroke patients.

CT perfusion imaging in the early diagnosis of acute stroke.

Early diagnosis of acute cerebral infarction is critical due to the time limit of thrombolytic treatment. Cerebral computed tomography (CT) perfusion imaging is a new technique, which appears to provide early diagnosis of major vessel occlusions in the brain. CT perfusion imaging also provides valuable information about the hemodynamic status of ischemic brain tissue. In this report, we present...
