Renal volumetry with magnetic resonance imaging

Renal volumetry with magnetic resonance imaging

BACKGROUND No gold standard exists for renal volumetry in vivo. PURPOSE To devise and evaluate segmentation methods on magnetic resonance imaging (MRI) datasets. MATERIAL AND METHODS Five combinations of MRI pulse sequences and measuring methods were used to measure the renal volumes of five men aged 54-72 years scanned before autologous renal stem cell transplantation and three, six, and 1...

Magnetic resonance imaging of feline eye

The purpose of this study was to investigate magnetic resonance imaging (MRI) of the normal feline eyeand optic nerves using T1-weighted and T2-weighted images. A total of 6 healthy female domestic short haircats age 2-2.5 years and weighing 3.2 ± 0.4 kg were selected. Magnetic resonance imaging data werecollected using GEMSOW (Philips) at a magnetic field strength of 1.5 T. Dorsal, sagittal, a...

magnetic resonance imaging (mri)

basic physical principles of nuclear magnetic resonance imaging (n.m.r.i), a nonionizing medical imaging technique, are described. principles of nmri with other conventional imaging methods, ie, isotope scanning, ultrasonography and radiography have been compared. t1 and t2 and spin density (s.d.) factors and different image construction techniques based on their different combinations is discu...
