PURPOSE To evaluate the impact of emerging conductor technology on RF coils. Performance and resulting image quality of thin or alternate conductors (eg, aluminum instead of copper) and thicknesses (9-600 μm) are compared in terms of SNR. METHODS Ei

Breast cancer is the most frequently diagnosed cancer in women. High field studies have shown the diagnostic value of breast MRI, but the examination costs greatly exceed those of competing conventional mammography. Low field MRI offers typical MRI c

Although MRI offers highly diagnostic medical imagery, patient access to this modality worldwide is very limited when compared with X-ray or ultrasound. One reason for this is the expense and complexity of the equipment used to generate the switched

Purpose TRASE (Transmit Array Spatial Encoding) MRI uses RF transmit phase gradients instead of B 0 field gradients for k-space traversal and high-resolution MR image formation. Transmit coil performance is a key determinant of TRASE image quality. T

Both 0.2 T and 9.4 T MRI systems were used to image a mouse model of glioma. RF coils were designed for both fields. A spin-echo, multi-echo pulse sequence was used to determine T(2) relaxation times of both brain and tumor tissues. Contrast-to-noise

A highly selective, high-power, multifrequency band-pass filter is presented. The construction of the filter is based on multifrequency tuned resonators used in magnetic resonance experiments. High values of the radio-frequency resonators' quality fa

The aim of this study was to find an optimum design for a volume RF coil for large rodent MRI/MRS at 4.7T and 7T. Three double-frequency birdcage-type coils were made and compared with single-frequency coils. The most efficient design was a birdcage

To perform multinuclear magnetic resonance spectroscopy and imaging, a coil with a high signal-to-noise ratio and spatially uniform B1 field that covers the same volume of interest at several frequencies is preferred. The design of a surface coil tha
