Background: In the last decade, sodium magnetic resonance imaging was investigated for its potential as a functional cardiac imaging tool for ischemia. Later interest was developed in contrast enhancement for intracellular sodium. Little success was reported to suppress extracellular sodium resulting in the intracellular sodium MRI image acquisition using quantum filters or sodium transition st...
BACKGROUND AND PURPOSE The goal of this study was to determine the CT findings and clinical consequences of contrast enhancement and contrast extravasation on CT scans obtained after intra-arterial thrombolytic therapy for treatment of acute ischemic stroke. METHODS Sixty-two patients were treated with intra-arterial thrombolysis. All patients underwent nonenhanced CT scans immediately and 24...
Background: One of the artifacts found on CT scan is a metal artifact. Metal are caused by objects present in patients’ bodies. The file can cover organ that will be evaluated, and it inferred with pixel value (CT number) assessment tissue around metal. Purpose: To determine effect band pass median filter find optimal to reduce head scan. Method: A total 43 samples patients’s files from CT-scan...
BACKGROUND Optimizing scan parameters for double inversion recovery (DIR) sequences remains difficult. OBJECTIVE To evaluate a new method for optimizing DIR sequence scan parameters using T1 mapping and a newly developed analysis algorithm. METHODS Twelve healthy volunteers underwent T1 mapping and DIR magnetic resonance imaging. The following steps were used for image optimization includin...
OBJECTIVES The aim of this research was to evaluate the potential for myocardial contrast echocardiography (MCE) to provoke microscale bioeffects in a canine model. BACKGROUND Myocardial contrast echocardiography induces bioeffects in rat hearts, but translation of such results to larger animal models is uncertain. METHODS Dogs were anesthetized and prepared for open- (n = 22) or closed- (n...
