Dynamic quantitative nonenhanced magnetic resonance angiography of the abdominal aorta and lower extremities using cine fast interrupted steady-state in combination with arterial spin labeling: a feasibility study

Cine fast interrupted steady-state in combination with arterial spin labeling is a recently described nonenhanced magnetic resonance angiography (MRA) technique that relies on bolus tracking for time-resolved ...

Purpose: To map and measure the depths of corneal neovascularization (NV) using 3-dimensional optical coherence tomography angiography (OCTA) at 2 different wavelengths. Methods: Corneal NV of varying severity, distribution, and underlying etiology was examined. Average NV depth and vessel density were measured using 840-nm spectral-domain OCTA and 1050-nm swept-source OCTA. The OCTA results were compared with clinical slit-lamp estimation of NV depth. Results: Twelve eyes with corneal NV from 12 patients were imaged with OCTA. Clinically “superficial,” “midstromal,” and “deep” c...

AbstractObjectivesCoronary CT angiography (cCTA) has been used to non-invasively assess both the anatomical and hemodynamic significance of coronary stenosis. The current study investigated a new CFD-based method of evaluating pressure-flow curves across a stenosis to further enhance the diagnostic value of cCTA imaging.MethodsFifty-eight patients who underwent both cCTA imaging and invasive coronary angiography (ICA) with fractional flow reserve (FFR) within 2  weeks were enrolled. The pressure-flow curve–derived parameters, viscous friction (VF) and expansion loss (EL), were compared with conventional cCTA par...

In this study, we attempted to discuss the key techniques for overlapping low-profile visualized intraluminal support (LVIS) stent-assisted coil embolization, which is used for treating BBAs in our center. Clinical characteristics, endovascular treatment details, outcomes, and follow-up results of 13 patients with BBA treated at our center were retrospectively evaluated in this study. Overlapping LVIS stent-assisted coil embolization was successfully performed in all 13 patients of ruptured BBAs located in the ICAs. Recurrence of aneurysm was observed in 4 cases (30.8%) during the angiographic follow-up; in 2 of these case...

Authors: Stević M, Vlajković M, Veličković F, Stanojević G, Nestorović M, Petrović F Abstract A 69 year old patient was admitted to hospital with massive gastrointestinal hemorrhage. The clinical presentation of the patient, except for bleeding, was dominated by the presence of neurofibromatosis type 1 - Von Recklinghausen disease. The patient was referred to multislice computed tomography (CT) angiography, magnetic resonance imaging (MRI), esophagogastroduodenoscopy and colonoscopy, which were performed without successful detection of the bleeding site. The MRI examination showed the existence of a tumor lo...

Authors: Štalc M, Jerman N, Trampuš M, Dolenc Novak M, Gužič Salobir B Abstract OBJECTIVE: To investigate the impact of myocardial perfusion scintigraphy results on the decision for invasive coronary angiography in elderly patients (≥75 years) with suspected coronary artery disease hospitalized in a single tertiary medical center. SUBJECTS AND METHODS: In the retrospective study, data of 276 (136 elderly) consecutive hospitalized patients referred to myocardial perfusion imaging were analyzed. The clinical characteristics, myocardial perfusion scintigraphy results, invasive coronary angiograp...

In the United Kingdom, coronary angiography is rarely performed of donation after brain death donors. Currently up to 30% of potential donor hearts are not utilised due to potential but unconfirmed coronary disease. For Donation After Circulatory death donors, coronary angiography is prohibited, as are all antemortem interventions. We believe that ex situ coronary CT angiography (CTA) will be logistically more feasible than in situ donor coronary angiography or ex situ coronary angiography allowing greater yield of donor hearts.

There is an unmet need for a noninvasive biomarker for cardiac allograft vasculopathy (CAV), that could obviate the need to perform surveillance coronary angiograms in HT recipients. Donor-derived cell free DNA (ddcf-DNA) has shown a good ability to rule out cellular rejection, but its performance as a biomarker for CAV has not been tested.We sought to evaluate the performance of ddcf-DNA as a biomarker of CAV in a cohort of patients undergoing routine coronariography.

Cardiac allograft vasculopathy (CAV) is a major cause of morbidity and mortality post heart transplant (HT). Coronary calcium has a sensitivity of 91% for the presence of>50% angiographic stenosis among the general population. Given the different pathophysiology of CAV and atherosclerosis, it is unclear whether visually estimated coronary artery calcification (VECAC) on CT attenuation correction (CTAC) scans can be used to detect CAV post HT and whether there is an association with long-term outcomes in patients with CAV.
