Dynamic contrast medium-enhanced computed tomography (CT), T2-weighted fat-suppressed spin-echo (T2FS) magnetic resonance (MR) imaging, and breath-hold T1-weighted fast low-angle shot (FLASH) MR imaging before and after dynamic gadopentetate dimeglum

The purpose of this work was to develop a multiple-breath-hold (BH) imaging method for coronary arteries in which a segment of k-space is acquired in each BH. The goal was to increase the resolution, or the signal-to-noise ratio (SNR) and coverage, o

New magnetic resonance (MR) imaging techniques possess features desirable for imaging the pancreas. Computed tomography (CT) and endoscopic retrograde cholangiopancreatography (ERCP) were prospectively compared with breath-hold fast low-angle shot (F

Tunneling spectroscopy is a rapidly developing method for obtaining vibrational spectra of monolayers of materials incorporated in tunneling junctions. To date, tunneling spectroscopy has been restricted to observing spectra of junctions that have be

A series of solenoidal NMR probes were built to measure T1 and T2 relaxation times in vivo in the mouse, over the frequency range of 5 to 60 MHz, using inversion-recovery and spin-echo pulse sequences. KHT tumors growing in the legs of C3H mice were

The technology of tunneling spectroscopy has been developed to allow the observation of in situ electron beam induced chemistry at liquid helium temperatures. In order to demonstrate the technique, we report the irradiation of a monolayer of cyanoace
