The purpose of this pilot study was to determine if two-dimensional perfusion angiography can be used to quantify tumor perfusion during mapping prior to Yttrium-90 (Y-90) transarterial radio-embolization (TARE) treatment and whether perfusion metrics correlate with tumor response and prognosis.

The use of CTP along with MRA, CTA, and angiography presents unique pearls and pitfalls in the community hospital setting. We hypothesize that this pictorial review and analysis will reveal trends and issues unique to the community setting that have not been exposed in prior research with implications relevant to practice.

Coronary computed tomography with myocardial perfusion imaging (CCTA-MPI) provides data on coronary anatomy and perfusion and may be useful in the assessment of ischemic coronary artery disease (CAD). Management of angiographically intermediate coronary lesions is challenging, and coronary fractional flow reserve (FFR) evaluation is recommended to assess whether these lesions are functionally significant. Our aim was to evaluate the diagnostic accuracy of CCTA-MPI in patients with stable CAD and at least 1 angiographically intermediate coronary lesion submitted to FFR. In this single-center prospective study, patients with...

The incidence of skin flap necrosis after mastectomies is as high as 11-24%. Laser-assisted indocyanine green (ICG) angiography seems to be a promising technique to assess skin flap perfusion. The aim of this systematic review is to assess the current methodology of ICG and its objective outcome measures ability to predict mastectomy skin flap necrosis.

ConclusionThe vessel-specific MCP myocardial perfusion territory assignment technique more accurately quantifies LCA and RCA perfusion territories as compared with the current standard AHA 17-segment model. Therefore, it can potentially provide a more comprehensive and patient-specific evaluation of coronary artery disease.Key Points• The minimum cost path (MCP) technique accurately determines left and right coronary artery perfusion territories, as compared with the American Heart Association 17-segment (AHA) model.• The minimum cost path (MCP) technique could be applied to cardiac computed-tomography angiograph...

CONCLUSION: Especially those renal transplant candidates with a cardiac history carry a high risk for a cardiovascular event post-transplantation. Uniformity in cardiac screening of renal transplant candidates and better pre-operative preparation might lower this post-operative risk. Besides, post-transplant anaemia should be prevented.

AbstractAimTo evaluate the effect of acute anaerobic exercise on macular perfusion measured by swept-source optical coherence tomography angiography (SS-OCTA) in young football players.Materials and methodsFootball players with ages between 18 and 20  years were included into the study. After a detailed ophthalmological examination, physiological parameters including height (cm), body weight (kg), body fat percentage (%), systemic blood pressure (BP) (mmHg), hematocrit values (%), oxygen saturation pO2 (%) and heart rate (bpm) were recorded. Intraocular pressure (IOP) (mmHg) and SS-OCTA using DRI OCT Triton (Topcon, T...
