MRI of the human eye using magnetization transfer contrast enhancement.
PURPOSE To determine the feasibility of using magnetization transfer contrast-enhanced magnetic resonance imaging (MRI) to track cataractous lens changes. METHODS A fast spin-echo sequence was modified to include a magnetization transfer contrast (MTC) preparation pulse train. This consisted of twenty 8.5-msec sinc pulses, 1200 Hz upfield from the water resonance and 1.2-Hz power. The MTC pre...

متن کاملResponsive paramagnetic chemical exchange saturation transfer MRI contrast agents
Molecular imaging research has shown great potential to assess the molecular compositions of tissues and provide critical information for clinical diagnoses [1]. These noninvasive assessments of molecular compositions may provide earlier diagnoses of pathologies, may predict therapeutic effects before the therapy is initiated and may provide earlier assessments of therapeutic effects soon after...
متن کاملMagnetization transfer contrast imaging of hepatic neoplasms.
A method of performing magnetization transfer contrast (MTC) using a pulse sequence based on a series of on-resonance binomial pulses preceding a conventional spin-echo sequence has been recently described. We investigated this technique in the evaluation of circumscribed hepatic neoplasms on a 0.5 T imager. Conventional spin-echo imaging was performed in 18 patients with hepatic neoplasms, 15 ...
