Proton T1 relaxation time of normal and abnormal urine.
Relaxation times T1 of normal and abnormal urine samples were measured with a 0.02 tesla MRI device in a spectrometric mode. Protein containing urine from patients with glomerulonephritis showed a slight shortening of T1 relaxation time. Radiographic contrast medium, pH, osmolality or glucose in diabetes did not significantly change the T1 relaxation time of urine. Urine can be used as a T1 relaxation reference in MR imaging of the pelvis even if the patient has received radiographic contrast medium or has diabetes or proteinuria for any reason.
