Abstract Funding Acknowledgements Type of funding sources: None. Introduction We sought to measure systemic transit time (STT) on MRI dynamic sequences images in patients based the recirculation time. In a subset patients, using same images, when abdominal aorta and at least part one kidney was available, we used 2-compartment filtration model approximate renal cortical plasma perfusion (RCPF)....

Kidney transplants have been evaluated using a radionuclide technique to determine perfusion index (PI), mean transit time (MTT), and the parameters in renogram curve (Tmax, T1/2, and T2/3). The values for Tmax, T1/2, and T2/3 were also determined in normal volunteers. The results indicated that the Tmax value was less than 2 minutes, one week after transplantation. The other data were within n...

Planet transit events present as attractive targets for the ultra-high-resolution capabilities afforded by optical interferometers. Herein is presented an evaluation of the possibility of detection of such events through measurement of high-precision closure phases with the MIRC instrument on the CHARA Array. Recovery of the transit position angle upon the sky appears readily achievable with th...

Kepler has revolutionized the study of transiting planets with its unprecedented photometric precision on more than 150,000 target stars. Most of the transiting planet candidates detected by Kepler have been observed as long-cadence targets with 30 minute integration times, and the upcoming Transiting Exoplanet Survey Satellite (TESS) will record full frame images with a similar integration tim...

1. The effect of infusion of isotonic saline on the circulation in the renal cortex in the dog was investigated by an external counting technique involving measurement of the transit times for 'Krypton and l 311-labelled albumin after rapid injection into the renal artery. 2. During saline infusion superficial renal cortical blood flow and overall cortical blood flow rose by 23 and 15%, respect...

background functional constipation (fc) and constipation-predominant irritable bowl syndrome (cibs)are two main subtypes of constipation that can be distinguished by the rome ii criteria. measuring colonic transit time (ctt) is an easy and cost effective way to evaluate constipation. this study was conducted to compare the ctt in patients with fc and cibs. materials and methods those patients w...
