Regional myocardial blood flow was measured during control conditions with radioisotope-labeled microspheres, and the phasic reactive hyperemic response to a 20-s transient occlusion was then recorded. (jci.org)
During the dipyridamole infusion, the increases in phasic blood flow, the distributions of regional myocardial blood flow, and the relationships between thallium-201 localization and regional blood flow were comparable to values previously observed in exercising dogs with similar occlusions.

Renal artery involvement was based on computed tomography and/or angiography findings. (jrheum.org)

these reversed immediately upon balloon deflation. (thejns.org)

The diagnostic and prognostic information available from captopril renography and the increasing availability of magnetic resonance angiography (MRA) have reduced the use of renal arteriography as a diagnostic tool, except in evaluating kidneys with intrarenal branch-artery stenoses and those with complex vascular anatomy, including multiple accessory arteries.
