The additional value of imaging (excluding Doppler) for the diagnosis and follow-up of giant cell arteritis.

[The additional value of imaging (excluding Doppler) for the diagnosis and follow-up of giant cell arteritis]. Presse Med. 2019 Aug 27;: Authors: de Boysson H, Aouba A Abstract Since 2000, imaging is frequently used for the diagnosis and follow-up of giant cell arteritis (GCA). At diagnosis, the demonstration on imaging of an involvement of the temporal arteries is useful to guide the temporal artery biopsy, or, sometimes, to replace it. Large-vessel imaging is nowadays currently performed as some studies indicate that 30 to 80% of patients might demonstrate involvement of the aorta and its branches, often silently. Aorta CT angiography, positron emission tomography or magnetic resonance angiography show a high sensibility to detect large-vessel inflammation, and have become in current practice and recent studies a supplementary criteria to classify or diagnose GCA. Many studies indicate a different prognosis in patients with large-vessel inflammation, highlighting the need to diagnose such involvement. Large-vessel imaging is important in the patients' follow-up to analyze how large-vessel inflammation evolves under treatment and to detect morphologic changes (dilations, dissections, or stenoses) that are more frequent in these patients. Recent European recommendations analyze the different imaging procedures available for diagnosis and follow-up of patients with GCA. PMID: 31471096 [PubMed - as supplied by publisher]

This study clearly goes against what has been the common wisdom for the last 30, 40 years” and may lead to less testing and invasive treatment for such patients in the future, said Dr. Glenn Levine, a Baylor College of Medicine cardiologist with no role in the research. Some doctors still may quibble with the study, but it was very well done “and I think the results are extremely believable,” he said. About 17 million Americans have clogged arteries that crimp the heart’s blood supply, which can cause periodic chest pain. Cheap and generic aspirin, cholesterol-lowering drugs and blood pressure medic...

Study Design. Retrospective cohort study. Objective. Compare a novel two-step algorithm for indicating a computed tomography angiography (CTA) in the setting of a cervical spine fracture with established gold standard criteria. Summary of Background Data. As CTA permits the rapid detection of blunt cerebrovascular injuries (BCVI), screening criteria for its use have broadened. However, more recent work warns of the potential for the overdiagnosis of BCVI, which must be considered with the adoption of broad criteria. Methods. A novel two-step metric for indicating CTA screening was compared with the American Coll...

CONCLUSION: There was a good agreement for the size of the NVs in both methods. OCTA can be used as a simple and non-invasive method to visualize retinal neovascularizations. PMID: 31711250 [PubMed - in process]

ConclusionIn patients with single or double vessel disease, indices of RFR, with or without coronary angiographic guidance of the reference coronary territory, are better discriminators of flow-limiting stenoses than hMBF and CFR.

ConclusionModern imaging technology provides multiple methodologies highly successful at detecting the ASA. The ASA can then be preserved intraoperatively, contributing to low paraplegia rates. We strongly recommend routine application of this technology to arm the surgeon with precise information about the specific patient's spinal cord blood supply.

AbstractBackgroundMany patients undergo percutaneous coronary intervention (PCI) without the use of non-invasive stress testing prior to treatment. The aim of this study was to determine the potential added value of guiding revascularization by quantitative assessment of myocardial perfusion prior to intervention.Methods and ResultsThirty-three patients (10 females) with suspected or established CAD who had been referred for a clinical coronary angiography (CA) with possibility for PCI were included. Adenosine stress and rest13N-NH3 PET, cardiac magnetic resonance (CMR), and cardiopulmonary exercise test were performed 4 &...

Conclusion In our sample of patients with isolated syncope, the prevalence of pulmonary embolism was 2.2%. This value is not sufficiently low to negate the requirement for a formal work up in the ED, even in the absence of chest pain or dyspnea. However, the large confidence interval precludes any strong conclusion.

ConclusionsUse of 0.8  mg versus 0.4 mg of NTG in routine clinical CCTAs significantly increased coronary volume determined from FFRCT analysis but did not alter FFRCT or V/M. Further evaluation of repeat CCTAs in a more contemporaneous fashion using varied nitrate doses and disease severity is needed.Key Points•Fractional flow reserve from computed tomography (FFRCT)is a noninvasive method for evaluating the coronary arteries and relies on nitroglycerin (NTG)to induce coronary vasodilation,but the impact of different NTG dosages is unknown.•Retrospective analysis evaluated use of different NTG doses on...
