tissue level myocardial perfusion is one of the most important prognostic factors after successful recanalisation of the occluded coronary artery in patients suffering acute st elevation myocardial infarction (stemi). the primary objective of the present study was to examine the relationship between videodensitometric myocardial perfusion parameters as assessed on coronary angiograms directly f...

objective(s) the aim of this study was to investigate the overall effect of cardiac vasoactive factors during coronary occlusion and reperfusion on peripheral vascular tone, using a sequential isolated rabbit heart-ear perfusion model. materials and methods isolated ears were perfused with the effluent of isolated hearts subjected to ischemia (30 min) and reperfusion (180 min, n=6). the compara...

BACKGROUND: There are insufficient data covering retinal and choroidal microcirculation in eyes with lattice degeneration.
 AIM: To investigate circulation degeneration using optical coherence tomography-angiography (OCTA).
 MATERIALS AND METHODS: The study included 10 patients 12 healthy individuals. All subjects underwent OCTA examination of the macula. Additionally, four patients, ...

fixed myocardial defects in both stress and rest images, could be artifactual as a result of soft tissue attenuation. to increase specificity and identify the false positive results, we used gated technique to evaluate the wall motion and wall thickening as an index to differentiate real ischemic lesions from artifactual defects. 93 patients were studied. in 46 patients (48.8%) fixed perfusion ...

tc-99m-mibi is an isonrtrile derivative used for evaluation of myocardial perfusion in recent years. in this preliminary report, 7 patients with coronary artery disease are evaluated with tc-99m-mlbl stress planar and sped studies. good correlation with coronary angiography is observed in these cases.in view of inherent technical problems present with thallium 201, tc-99m-mibi is a good alterna...

testicular scintigraphy has been well validated in the evaluation of patients with suspected testicular torsion and provides an accurate evaluation of testicular perfusion at the lime of imaging. however, the presence of normal or increased perfusion to the testis does not definitively exclude the necessity for surgical intervention. a case of intermittent testicular torsion, with a review of t...

Abstract Introduction The optimum conditions for normothermic machine perfusion (NMP) in kidney transplantation have yet to be determined. Traditionally, kidneys are perfused with a red blood cell (RBC) based solution at 37°C. NMP subnormothermic temperature without RBCs could reduce the harmful effects of haemolysis but still preserve function. This study examines effect acellular (SNAP) human...

We simultaneously assessed the blood flow index (BFI) in three respiratory muscles during hyperpnea and high-intensity constant-load cycling sustained at comparable levels of work breathing neural drive patients with COPD. demonstrated that exercise impairs muscle perfusion, as intercostal, scalene, abdominal BFI increased but not cycling. Insufficient adjustment perfusion was associated greate...

  Bilateral diffuse intense breast uptake was noted in a 40 year old female who was evaluated with Tc-99m sestamibi (MIBI) myocardial perfusion scan for possible ischemia. She was breast feeding her 1.5 year old child. The intense uptake in the breasts was superimposed on the apical and anteroapical regions of the myocardium and caused interpretation problem. We recom...

The aim of this work is to analyze quantitative data magnetic resonance ASL-perfusion the liver at admission and follow up patients with viral cirrhosis. study included 34 cirrhosis: 23 (67.6 %) men 11 (32.4 women. All subjects underwent abdominal ultrasound Dopplerography vessels, shear wave elastography, Arterial spin Labeling (ASL) — Perfusion by imaging. Post-processing images was carried o...
