Measurement of regional myocardial blood flow with multiple colored microspheres.
TL;DR: Measurement of RMBF with CM yields values very similar to those of RM, which is less expensive and avoids all the disadvantages related to radioactivity, thus offering an alternative method for as many as five R MBF measurements in a single experiment.
Journal ArticleDOI
Current Status of Developments and Applications of Micro-CT
TL;DR: Although radiation exposure is becoming a concern with the drive for increased spatial and temporal resolution, gated scans and limited scan-data-set reconstruction algorithms show great potential for keeping radiation exposure to a minimum.
Journal ArticleDOI
Blood flow distributions by microsphere deposition methods
TL;DR: The art and science of the use of deposition markers for the estimation of blood flow distributions throughout the body and within organs is reviewed andStrengths and weaknesses of the various methods are compared.

V/Q distribution and correlation to atelectasis in anesthetized paralyzed humans.
Leif Tokics,Göran Hedenstierna,Leif Svensson,Bo Brismar,Torsten Cederlund,H Lundquist,Å. Strandberg +6 more
TL;DR: Shunt during anesthesia is due to atelectasis in dependent lung regions corresponding to the atelectatic area, with considerable V/Q mismatch, with ventilation mainly of ventral lung regions and perfusion of dorsal regions.
Journal ArticleDOI
Gravity is an important but secondary determinant of regional pulmonary blood flow in upright primates.
TL;DR: The distribution of pulmonary blood flow in baboons was explored because their anatomy, serial distribution of vascular resistances, and hemodynamic responses to hypoxia are similar to those of humans and because of anatomic similarities, the same may be true for humans.
