A study comparing SPECT with CT and MRI after closed head injury.
After closed head injury nineteen patients had single photon emission tomography (SPECT) using the lipophilic tracer 99m-Technetium hexamethyl-propylene-amineoxime (HMPAO) to compare the defectsExpand

Non-invasive assessment of diffuse liver disease by in vivo measurement of proton nuclear magnetic resonance relaxation times at 0.08 T.
44 patients with a range of parenchymal liver diseases diagnosed by biopsy or laboratory investigations underwent proton nuclear magnetic resonance (NMR) relaxometry of the liver at 0.08 T. T1 mapsExpand

Magnetic resonance imaging of urinary calculi
Accurate prediction of the response of an individual patient to lithotripsy remains impossible. Certain factors such as the chemical composition, size, and position of the calculus are known to beExpand

Proton NMR relaxation times in the normal human liver at 0.08 T.
The spin-lattice (T1) and spin-spin (T2) relaxation times of liver in 42 normal volunteers (21 male and 21 female) were measured using a calibrated 0.08 T resistive imager capable of accurate andExpand

In Vitro Magnetic Resonance Scanning of Urinary Calculi
Clinical experience with ESWL has shown that the size and composition of urinary calculi affect success. Knowing the composition of a stone before treatment is therefore desirable. We have examinedExpand
